When do you meet castiel

Jack wounds Michael, but then has his grace stolen by Lucifer. So Dean agrees to be Michael's vessel and kills Lucifer, at the cost of losing control of his body. At the beginning of season 14, Castiel is committed to finding Dean, who was possessed by Michael and disappeared after defeating Lucifer.

He resorts to a demon, Kipling , who lures him into an ambush and uses Castiel as a bargaining chip to meet Sam and get his support to become King of Hell. Together, however, Sam and Castiel defeat Kipling and his henchmen. Dean is found, in full possession of his conscience and with no sign of Michael. Jack, however, begins to decline in health, having lost his grace earlier, and then dies. The Winchesters seek Lily Sunder to help resurrect Jack, and Castiel goes to heaven to find his spirit and bring him back to his body.

Heaven, then, falls under attack from the Shadow, who wants to take Jack to the Empty. In order to stop him, however, Castiel convinces the Shadow to take him in exchange for Jack; the Shadow agrees, but says that he will not take Castiel's life until much later, when the angel will have forgotten their conversation and experienced a moment of happiness. Jack is resurrected and, with the help of Sunder's magic, he defeats Michael and consumes his grace, thus regaining his powers; during the battle, however, he had to burn out what was left of his human spirit, getting in a state similar to that of soulless humans, amoral and without emotions.

In that state, he kills Mary Winchester , causing Dean to turn against Castiel, as the angel had hidden from him what'd happened to Jack. In the end, Chuck reappears and tries to manipulate the Winchesters and Castiel to kill Jack in a showdown at a cemetery, but the trio refuses, causing Chuck to personally smite Jack and Team Free Will to then attack him.

Furious, Chuck opens up all closed doors of hell and lifts undead corpses from their resting ground, thereby causing the second apocalypse. The Winchesters and Castiel try to stand their ground against the zombies awakened by Chuck. They receive unexpected help from Belphegor , a heretofore unknown demon who, to Castiel's chagrin, is possessing Jack's dead body. To stop the ghosts from leaving the tear that Chuck opened on the surface of Earth, which leads to hell, and neutralize those who already made their departure, Rowena joins the group to perform a Book of the Damned spell, while Castiel and Belphegor descend to hell in search for Lilith's Crook , an instrument manufactured by the white-eyed demon that can suck in demons and ghosts who try to escape hell in disobedience.

Castiel, who is suspicious of the demon, initially refuses to escort him back to hell, but is forced to do so by Dean, who still resents the angel and doesn't want him around. Castiel discovers Belphegor wanted his company so that he could read the Enochian incantation that can open the Crook's box, and that his plan all along was to use the object to absorb the spirits of hell into himself, become more powerful, and take over hell's throne.

Castiel throws himself at Belphegor while he plays the instrument, smiting him so badly that Jack's corpse is burned to a crisp and the Crook is destroyed. Castiel manages to return to the surface of the Earth, and he tells Dean he couldn't let Belphegor fulfill the plan to suck in all of hell's souls, enraging Dean - against his friend.

Since the Crook is gone, Rowena decides to cast a spell so that she can herself absorb the spirits inside her own body, dying in the process. The death of their witch ally further intensifies Dean's anger at Castiel, and in an argument at the bunker he throws in the angel's face that everything that goes wrong in the group's endeavors has been Castiel's fault.

Tired of weathering the storm of his friend's moods, Castiel says that he is dead in Dean's eyes and so it is best that he move on without the Winchesters. Later, he ignores Sam, who tries to contact him via phone messages.

Castiel subsequently returned to the brothers to help them defeat God by grooming a resurrected Jack to become stronger. After the plan fails and they are chased by Billie, Castiel sacrifices him by confessing his love for his close friend and allows himself to be happy.

This activates his deal with the Shadow who drags him and Billie into the Empty. He is later resurrected again by Jack after he becomes the new God , as Bobby Singer tells Dean that Castiel helped Jack to reshape Heaven for the better.

Castiel's legacy has seemed to have become legendary among angels and demons alike, as many recognize him as the only angel who defied God's rules and cooperated with humans due to his own decision, which he is either loathed or respected for. He is also the only angel to have been killed, and been resurrected multiple times.

He is the only known angel who has repeatedly been resurrected by God so he could help Sam and Dean Winchester. As an angel , experiencing Castiel's true form will result in blindness, deafness, or even death, as the appearance of his natural visage is so overwhelming that it is capable of burning human or demon eyes from their sockets as seen in Lazarus Rising , as he said to Dean, " My true form.

It can be overwhelming to humans and so can my real voice. Although his true form has never been seen, it is known that he has two feathered wings. When Castiel becomes a seraph, he describes himself to Samuel Campbell as a "multidimensional wavelength of celestial intent" [6] and his true form is " approximately the size of your Chrysler Building " [14] in height. As he was promoted to a seraph, it stands to reason his true form has changed to one of a seraph's.

It is presumed to be very tremendous and terrifying, as the mere image of it was enough to cause Crowley to flee in fear of being smited.

In addition, Castiel has been referred to as being attractive on more than one occasion, both in his human vessel and his true angelic form. One female demon , while talking with Crowley, once instantly said Castiel was, as she said in her words, hot, as she also said, " I mean, human Castiel? But, feathered Castiel? Though he has since regained the remnants of his grace and been restored to full power, his wings are broken.

For humans, they see him as the appearance of his vessel, Jimmy Novak , who is a handsome man of average height in his thirties. He sports a pair of dress shoes, a black suit, a buttoned white-striped dress shirt, and loosened blue necktie accentuated by a beige trench coat. Although he has a very dire demeanor, his outward appearance radiates a natural calm and serenity which makes conversation easy and direct. Since his third resurrection, his appearance has changed.

He lost his trench coat upon his third death and when he became amnesic, he wore different clothes. Upon regaining his memories, Dean gave him back his trench coat, but he still wore Emmanuel's clothes until he became insane. While insane he wore his trench coat and hospital scrubs. While in Purgatory he retained the same outfit, albeit extremely dirty and torn off. Castiel also grew a beard and his hair became messier. After returning from the monster realm, Castiel returned to his original appearance.

He kept this until he lost his grace and became human. While he initially kept his usual clothes, they became dirty and he was unable to clean them and get food and water so he abandoned the trench coat and suit and took to wearing more casual human clothes, though he did wear a suit when he pretended to be an FBI agent.

After becoming an angel again, Castiel donned a new suit and trench coat, albeit not as accented as his previous trench, nor as long. He at first didn't wear a tie like before, but after a suggestion from Claire Novak that he looked better in a tie, Castiel donned the blue striped tie from his FBI suit and continued to wear it in the next seasons.

As of Season 13, Castiel returns to his classic attire of seasons with a new black suit, and trench coat. His tie is once again a single shade of blue. In , Castiel possessed a female vessel and dressed as a woman from that era.

Notably, he wore a coat very similar to the trench coat he wore in his first appearance. It is safe to say that, like most angels, Castiel does prefer to retain his vessel's original appearance and clothing. He does not seem to have a high fashion sense, preferring neatness over beauty. Like most angels , Castiel expresses little to no emotion, which creates flaws and complexities in his persona.

Despite this, he does not display the blank apathy or mocking superiority that seem to characterize angels such as Uriel or Lucifer. Basically, it's kind of impossible to tell whether any angel is going to be Castiel's ally or not.

Supposedly, an angel's true form and true voice are so awesome to behold and behear that ordinary humans would get vaporized or some such nonsense from doing so. Supernatural has held fast to this arbitrary rule, never once showing Castiel's true form to the audience.

At this point, fans have started to wonder if it's just because of laziness. Supernatural has shown all kinds of impossible sights over the years. While the effects tend to be pretty low-budget, you have to wonder if they don't show the angels' true form because they never actually imagined it, instead choosing to just vaguely describe it.

Ah, well, maybe someday we'll see Castiel unleashed. What, exactly, would you say to the girl whose father you were currently wearing like a shirt? There's no way Castiel's relationship with Claire Novak could ever be described as healthy, given that her deceased father's body has become Castiel's permanent vessel.

Castiel has never proven to be adept at social situations. You'd probably become a rebel, too, if your dad had been replaced with an angel that didn't know you. Can you really blame Claire for acting out, or the relationship for becoming uncomfortable? The whole dynamic admittedly makes sense-- and attempted to set up Claire for the failed Wayward Sisters spinoff-- but honestly we'd rather we didn't have to cringe at it anymore.

One of Castiel's core personality traits is his willingness to believe in the goodness of others, especially when they present as an ally of God. This has led him to allying with some unsavory characters, though some were to be expected: teaming up with angels like Metatron or Uriel makes sense for a trusting angel, at least until he learned of their ulterior motives.

There are some alliances that Castiel just should never have made. In later seasons, Castiel even began tolerating certain demons, making alliances and uneasy truces with some powerful figures in the underworld. Crowley and Meg were chief among these-- though Castiel ended up betraying Crowley in their first team-up. Frankly, it's getting kind of old how Castiel keeps getting in bed with the bad guys.

Season six of Supernatural did not exactly showcase Castiel on his best behavior. Specifically, his overarching storyline focused on him fighting a civil war in heaven against the archangel Raphael, and he did more than a few unsavory things to achieve his goals. One of the worst came in the 17th episode of the season.

In that episode, Balthazar changes history so that the Titanic never sank, and this angers the Fates, who begin destroying all the victims' descendants that weren't alive in the original timeline. The Fates then threaten the Winchesters, and Castiel goes back in time and causes the Titanic to sink again, saving the brothers and erasing the 50, descendants.

You wouldn't really think a literal angel would sacrifice thousands of souls to save two, but you'd be wrong. You might think, given that Castiel is an angel and therefore one of the most powerful beings in creation, that he wouldn't need much help in his adventures on Earth. Well, you'd be wrong, as Castiel's life has been saved a wide range of friends-- not to mention some foes.

Obviously, the Winchester brothers and other humans have helped Cas out in a pinch from time to time, but some unsavory characters have done the same.

Demons like Meg and Crowley have saved Castiel's life, meaning that the angel owes his life to his sworn enemies. A constant refrain you'll hear from critics and fans when watching a show that has gone on for many seasons: the first seasons were the best ones.

While there's no irrefutable proof that any season of Supernatural is the best, the first few seasons have their share of fans saying the show jumped the shark later on. Why does this affect Castiel? As the angels are about to take her, an injured Ruby appears with Alastair. The demons and angels confront each other and a fight ensues. During the confrontation Castiel faces off with Alastair, landing several blows and trying to cast the demon back into the Pit.

It proves ineffective and Alastair pins Castiel to the ground, strangles him and starts a demonic chant. Castiel is saved from Alastair's grip when Dean hits the demon across the back with a tire iron and distracts him from Castiel. During the fight Anna steals her grace from Uriel and becomes an angel again. During her transformation, Alastair disappears and his host is destroyed. Uriel and Castiel leave, and it is discovered that Sam had planned all along to bring the demons and angels together to get them to fight each other.

Castiel, pretending to be Bobby Singer , tells Sam by phone about a scenario described in a version of Revelations:. This is one of the 66 Seals which will be broken if two reapers are killed under a solstice moon. Castiel needs Sam and Dean to prevent the killing because the demons responsible are holed up in a refuge covered in Enochian sigils that prevent angels from entering. The boys are successful in preventing the seal from being broken, and in the process Castiel captures Alastair.

After talking with a reaper, Dean asks Castiel why, if death is part of the natural order, he was rescued from Hell. Castiel replies "You're different. In the first scene, Castiel finds an angel from his garrison dead. Castiel and Uriel then appear in the Winchesters' hotel, explaining to Dean that the torturing skills he learned in Hell are required to break Alastair so that they can identify which demon is killing angels.

Dean refuses to accompany them, but Uriel and Castiel transport him to the place where Alastair is kept in spite of this protest. Once there, Dean insists on speaking to Cas alone. Uriel departs. Castiel then explains that he has been placed under Uriel's authority because his superiors feel he is too emotionally involved with the Winchesters.

They believe that this is impairing his judgment. Castiel tells Dean that the angels need, rather than want, him to do this. Dean is convinced, and enters the room where Alastair is held. Castiel waits outside, listening. Anna arrives and attempts to convince Castiel that forcing Dean into torturing again is morally wrong, and that it could not truly be God's orders.

Castiel is clearly uncertain. Anna approaches him, explaining that she felt doubt before she left Heaven. She tries to persuade him that together they could find an answer.

Castiel backs away from her, insisting that they have nothing in common because she fell. He tells her to leave, and she does. Meanwhile, Alastair is freed from the devil's trap and attacks Dean. Castiel enters the room and fights him, but Alastair manages to trap him. Alastair then begins to chant a demonic spell to send Castiel back to Heaven, but Sam interrupts him using his demonic powers, saving Castiel.

Alastair is killed by Sam after insisting that no demon is responsible for the deaths of the angels. Later, Castiel confronts Sam at the hospital where Dean is being treated.

Sam assures Castiel that Alastair was not lying. Uriel and Castiel meet at a playground to talk about how "something is wrong" in Heaven. Castiel then calls Anna and tells her that he is considering disobedience; however, he does not believe it is "good. She tells him to make his own decisions. Castiel returns to the warehouse where Alastair was kept and finds out that a leaky pipe enabled Alastair to escape from the devils trap.

Uriel arrives while Castiel is examining the trap. Castiel declares that he built the old Enochian trap, and insists that a demon could not have defeated it. He demands to know the truth. Uriel admits that he was responsible for the deaths of the 7 angels, and that he wishes Lucifer to rise and humanity to be destroyed. He has been converting other members of the garrison to this viewpoint, and killing those that disagreed. Uriel attempts to recruit Castiel, but fails, and Castiel attacks him.

Uriel fights back, bringing Castiel to his knees. Anna arrives clandestinely and stabs Uriel from behind, saving Castiel. Castiel visits Dean in the hospital and confirms that Dean's actions in Hell resulted in the breaking of the first seal. When Dean asks why he was not left in Hell, Castiel responds that "the righteous man who begins it is the only one who can end it. Sam and Dean have encountered Chuck Shurley , a man who has written detailed accounts of the Winchesters' lives.

Everything Chuck writes seems to come true. When Chuck predicts that Sam will encounter Lilith , Dean, afraid for Sam, angrily insists on an explanation of the writings. He threatens Chuck with violence, but Castiel arrives to stop Dean and reveals that Chuck Shurley is a Prophet of the lord. His books will one day be known as the Winchester Gospels. As a prophet, Chuck must not be harmed. Dean returns to his motel to find that Sam has burned the protective hex bags Dean made.

He is seeking the confrontation with Lilith that Chuck foresaw. Frustrated, Dean threatens to leave Sam to his fate, but changes his mind and instead storms out into the parking lot. Desperate, Dean starts to pray and Castiel appears, pleased by the sign of faith. Dean asks for help in preventing what Chuck has predicted, but Castiel refuses to interfere directly, saying that what a prophet has seen will come to pass. However, Castiel explains that Chuck is watched over by an archangel that will annihilate any threat to the prophet, including a demon like Lilith.

Dean thanks him and uses the information by putting Chuck in the same room with Lilith as she and Sam are about to fight. This causes the archangel to appear, and Lilith flees.

Castiel appears in a dream to Dean, and asks him to meet him in the real world because there is something he needs to tell him. When Dean and Sam arrive at the address provided by Castiel, they find signs of a violent confrontation.

They encounter Castiel's vessel, Jimmy Novak, and determine that Castiel has been taken back to Heaven by force. Castiel's vessel Jimmy Novak remembers little, but describes being possessed by Castiel as being "chained to a comet". Jimmy is anxious to return to his family. Sam and Dean try to prevent him from leaving, but Jimmy escapes. He returns home, but demons soon intrude, trying to capture the "empty vessel. Jimmy goes to meet the demons and is shot as a captive Sam and Dean watch.

Suddenly Castiel returns, possessing Jimmy's daughter Claire Novak. She, like Jimmy, is an angelic vessel, having inherited the something "is in his blood" that made Jimmy a vessel. After defeating the demons, Castiel agrees to Jimmy's dying plea that Castiel use him as a vessel instead of his daughter. As Castiel leaves, Dean asks him what it was he wanted to tell them, but Castiel rebuffs him, saying that he learned his lesson in Heaven.

He doesn't serve man After discovering that Sam has been drinking demon blood , Dean and Bobby imprison him in Bobby's panic room. Dean calls on Castiel, demanding to know if Sam is capable of killing Lilith.

Castiel says yes, but that consuming the amount of demon blood required would make him inhuman. Castiel reiterates that the angels believe Dean can be the one to stop the apocalypse, rather than Sam, and asks if Dean will accept that role.

Dean agrees for Sam's sake, and swears fealty and obedience to God and the angels at Castiel's insistence. Later Castiel comes secretly into Bobby's house and uses his powers to release Sam's bonds and open the door to Bobby's Panic Room. Sam escapes, and Castiel leaves. Anna visits Castiel at a waterfront, and confronts him over his actions, but he says he is acting on orders.

He tells her that she should not have come to see him, and she is taken captive by other angels. Castiel and Zachariah hold Dean captive in the Green Room , waiting as the apocalypse approaches. Dean pleads with Castiel to let him see Sam, but Castiel refuses, saying that it is not advisable. The doors of the room are removed to prevent Dean's escape. Later, after Zachariah reveals the angels' real plan, Castiel returns and apologizses to Dean for deceiving him.

Dean is angry, and argues with Castiel, trying to convince him to help stop the apocalypse. Cas initially refuses, arguing that they would all be hunted. They argue, and Cas leaves. He then returns abruptly, forces Dean against a wall, and signals for silence. Cutting his forearm, Cas draws a sigil on the wall in blood. Zachariah arrives to stop him, but Castiel places a bloody hand on the sigil and Zachariah is sent away. Castiel says he will take Dean to Sam to stop him from killing Lilith - because her death IS the final seal.

An archangel arrives, and Castiel says he will hold it off and sends Dean directly to the Convent. Castiel and Chuck wait for the archangel as the house continues to shake. Early in the episode, the Winchesters visit Chuck Shurley to discover what happened to Castiel when the archangel attacked at the end of 4.

Chuck reveals that Castiel was killed, that he exploded "like a water balloon of chunky soup. After luring the Winchesters to their father's storage unit, Zachariah reveals that Dean is the archangel Michael 's vessel. Dean refuses to act as a vessel, so Zachariah tries to coerce Dean's agreement by torturing both Dean and Sam. Suddenly, Castiel appears. He attacks the two angels Zachariah brought with him, killing both with an angel blade. He then orders Zachariah to heal Sam and Dean, then leave.

Zachariah complies. Castiel informs the brothers that Lucifer is preparing to take a vessel and that they must be on their guard. He touches Sam and Dean, burning Enochian sigils into their ribs that will hide them from all angels, including Lucifer. When asked what brought him back to life, Cas does not answer, and vanishes.

Castiel calls Sam to find out where the boys are; he cannot locate them because the Enochian sigils he etched into their ribs hide them from all angels, including himself. He meets them at the hospital where Bobby is being treated.

He reveals that he is cut off from Heaven following to rebellion, and has lost some of his powers, including the ability to heal. This means that he cannot help Bobby. He then says that in order to defeat Lucifer he plans to find God. He asks Dean for his amulet , which Cas says will burn hot in God 's presence. Dean mocks Castiel's plan, and Cas responds angrily, detailing what he has done for the Winchesters and what he has lost as a result. Dean relents and gives him the amulet, with orders not to lose it.

Castiel visits Dean in a hotel room to ask for help. He wants Dean to help him find Raphael , the archangel who killed Castiel. Cas hopes to trap and interrogate Raphael, forcing him to divulge the location of God. Castiel also says that he is asking because Dean is "the only one who'll help me". Dean agrees to go along, but only if they drive.

Cas and Dean arrive in the Maine town where Raphael was sighted and go to the local sheriff for information. Cas wants to tell the sheriff about Raphael, but Dean persuades him that the truth is not a good idea in this situation. He gives Castiel an FBI badge and straightens his tie. After an awkward and amusing conversation with the sheriff, they discover that Raphael's vessel has been taken to a local hospital.

Cas decides to trap Raphael using a very dangerous ritual involving holy oil obtained from Jerusalem. He admits to Dean that even though Dean, as Michael's vessel, will not be harmed, Castiel may not survive. Dean considers this, and asks Castiel what he would like to do on his last night on Earth. Dean throws out a few suggestions, and discovers from Cas' reactions that the angel is a virgin.

In response, Dean takes Cas to a brothel. At a table in the bar area, Castiel looks terribly uncomfortable. Dean orders him to relax, to no effect. A girl comes over and Dean introduces her to Castiel. She leads the nervous angel to a back room, leaving behind a bemused Dean. A few moments later, a scream from the back sends Dean in search of Cas, who is being yelled at by the frightened sex worker.

It seems that Cas tried to comfort the girl by telling her it wasn't her fault that her father ran away; it was because he hated his job at the post office. Dean laughs, and the two of them run as a pair of bouncers appear. The next morning, Dean and Castiel place Raphael's vessel in a circle of holy oil in his room at the hospital.

Castiel chants in Enochian to summon Raphael, then lights the oil. Raphael does not manifest, and hours later Dean and Castiel return to their base in an empty house. Raphael, occupying his vessel, is inside when they enter. He threatens to take Dean to Michael, but Dean lights a hidden circle of holy oil, trapping the archangel. Castiel and Raphael argue, with Raphael insisting that God is dead. Castiel refuses to believe him, and he and Dean leave Raphael trapped in the circle of fire.

Later, Castiel says he believes God is out there, and that he will keep searching. Castiel phones Dean, eager to meet up and search for the Colt , but Dean begs that he wait until morning. Castiel agrees and continues standing, rather forlornly, on the side of a highway. Dean wakes in the morning to find that Zachariah has zapped him five years into the future, into In appears that in , Lucifer's minions re-released the Croatoan demon virus. In this post-apocalyptic world, most humans have been reduced to murderous zombies.

Dean goes in search of Bobby, and finds a photo showing that Castiel is at Camp Chitaqua. Future Castiel informs Dean that sometime after the Croatoan virus was released, the angels left, and so did most of his angelic powers, so that Cas is now effectively human.

He can however detect that Dean from is different from Future Dean. He is embittered at his situation and has immersed himself in "women and decadence". When Dean first encounters him, he is organizing an orgy, and when Dean asks if he is stoned, he says "Generally - yeah. Future Castiel is presumably killed during the attack Dean leads on Lucifer. When Zachariah brings Dean back to the present, he once again asks him to be Michael's vessel.

When Dean refuses, Zachariah is about to take him prisoner and torture him again, but Castiel intervenes, transporting Dean to safety at the roadside where Cas has been waiting. Dean comments on his good timing, and Castiel smiles, saying "we had an appointment". Dean tells him not to ever change and later calls Sam to bring him back.

Sam and Dean ask Castiel for help when they discover that Jesse Turner is a cambion , the son of Julia Wright and a demon. Castiel insists that Jesse must be killed as he is incredibly powerful, even capable of "killing the Host of Heaven with one word. However, when he attempts to kill the boy, Jesse turns Castiel into a small action figure.

Castiel is restored when Jesse leaves and goes into hiding. When the Trickster traps Sam and Dean in an unending series of TV shows, Castiel tries to rescue them but is banished. When he reappears, Castiel is bloodied and bruised, and says he thinks it may be something more powerful than the Trickster - who appears and again banishes him. Finally, after the Trickster is revealed to be Gabriel , Dean gets him to bring Castiel back. Castiel discovers the crossroads demon Crowley making a deal with a banker.

He follows the demon to the house Crowley is occupying, and informs Dean of its location by phone , then reveals that the house is protected from angels by Enochian symbols.

Sam and Dean recruit Ellen and Jo to help with the mission, and the four of them breach the house. Sam and Dean find Crowley and are shocked when he willingly hands over the Colt and the location of Lucifer. The team regroups at Bobby's, and Castiel does shots with Ellen and Jo after the latest 5 he declares that he's "starting to feel something".

The hunters prepare to take on Lucifer in Carthage, Missouri, and Bobby insists on taking a photo of them all so he has something to remember them by. The others laugh off Bobby's comment, but Castiel observes that "Tomorrow we hunt the Devil.

This is our last night on earth. When the team arrives in Missouri, Castiel sees reapers everywhere. He follows one, trying to find out why they are there and is captured by Lucifer, who imprisons Cas in a ring of flaming holy oil. Lucifer describes Castiel as a "peculiar thing," and questions him about his arrival and who he has brought with him.

He tries to convince Castiel to join him, because Castiel will be Heaven's target if Lucifer is defeated, but Castiel refuses. Lucifer leaves to finish his ritual, leaving Meg to watch over Castiel. Castiel manages to loosen the fittings on an overhead pipe and uses it to knock Meg into the flaming circle.

Castiel tries to cast her out of her host, but finds that without Heaven's support he is unable to do so. Meg mocks him as powerless, and Castiel throws her onto the holy fire, walking over her to escape. He arrives in time to save Sam and Dean from Lucifer. Anna comes to Dean in a dream, telling him that she has been held prisoner in heaven after being turned in by Castiel, but has escaped.

She wants Dean to meet her, but instead of Dean, Castiel arrives. He does not believe she could have escaped on her own, having himself experienced "Heaven's persuasion". He accuses her of working for Heaven against the Winchesters. Anna denies this, but insists that Sam must die so that Lucifer cannot take him as a vessel.

She fails to convince Castiel, who refers to Sam as his friend. He informs her that, despite their shared experiences, if she attempts to harm Sam, he will kill her. Later, after informing Sam and Dean of the situation, Castiel performs a ritual to determine Anna's location. He discovers that Anna has gone back in time to kill Sam and Dean's parents. Sam and Dean insist that he bring them along, but Castiel protests that time travel is extremely difficult, even with Heaven's support.

Because he is outcast, he tells them that "taking this trip, with passengers no less However, he gives in to their continued insistence and packs a satchel containing holy oil and his angel blade, then gives it to Sam.

Cas touches the brothers' foreheads, and suddenly they arrive in the year Sam and Dean find Castiel slumped against a car, bleeding and breathing heavily. He insists that he is better than he expected to be, but then coughs up blood and passes out. Dean books Castiel into the honeymoon suite at a hotel to regain his strength while they fight Anna.

Sam is concerned about Cas, but Dean describes him as "tough for a little nerdy dude with wings". After Sam and Dean are returned to their time by Michael, Castiel appears in their hotel room. He does not immediately realize where he is, but when informed that he has made it back, he admits to being very surprised. He passes out, and the brothers drag him over to a bed to rest. Sam and Dean investigate cases of people who abruptly kill themselves in odd ways near Valentine's Day.

While examining the remains of the victims post-autopsy Sam notices an inscribed angel sigil on two of the hearts. Dean phones Castiel for angelic assistance. Cas appears directly in front of Dean while they are still on the phone. He recognizes the sigils as a mark of union placed on the victims by a Cupid , a lower angel called a Cherub. Castiel, Sam, and Dean go to a couple-filled restaurant, suspecting that Cupid will be drawn to the love-filled environment.

While there, Cas asks to eat Dean's untouched hamburger, but before he can take a bite he senses the Cupid has arrived. Castiel traps Cupid in the back room of the restaurant and forces him to show himself. Cupid manifests as a naked man and goes around giving Dean, Castiel and Sam enthusiastic hugs, lifting them up off the floor.

Castiel informs them that this is the Cupid's way of shaking hands, and that no one likes it. The three interrogate the cherub about the strange deaths, and he begins to cry. Castiel tries to comfort him, earning another intense hug. The cherub then asks Cas to read his mind so that they will understand that he was not involved in the deaths. Cas agrees and makes eye contact with the other angel. After a moment he turns away, announcing that Cupid is telling the truth. Later, Sam fights a demon and takes its briefcase.

At their motel, Sam and Dean open the case and release a brilliant light. Castiel appears behind them, holding a paper bag of hamburgers, and explains that the brothers released a soul. As he eats the hamburgers, Castiel announces that Famine is in town and is causing the strange, starved behavior among the victims. Even Cas has been affected through his vessel, Jimmy, who craves red meat.

Once strengthened by consuming souls, Famine will be able to march across the lands with authority. Sam is incapacitated by his craving for demon blood, so Castiel and Dean search for Famine.

Cas continues to eat, saying that the hamburgers make him very happy. They locate Famine, but Castiel is distracted by a tray of raw ground beef and Dean is captured.

Sam arrives after killing two demons and drinking their blood. Castiel tries to reassure Dean that Sam will be okay when the blood is out of his system, but Dean leaves. Sam and Dean are killed, and Dean wakes up inside his Impala. Young Sam is there, and Dean realizes he's reliving a happy memory. When Dean remembers that he and Sam were shot, the memory disappears, and Dean hears Castiel's voice coming from the Impala's radio.

Castiel tells Dean that he is dead and is in Heaven. He urges a confused Dean that he must follow the asphalt road in front of him if he is to find Sam. The connection between Castiel and the radio, made possible by a spell, fades, and Dean is on his own again. Dean and Sam are reunited in a Thanksgiving memory of Sam's that takes place in an old girlfriend's house.

Suddenly a bright light streams through the windows and shakes the ground, forcing Sam and Dean to hide behind furniture in the living room. When the light has passed, a TV turns on. Castiel's face appears on screen, and though the message is grainy and full of static, they can communicate. Castiel warns them "Don't go into the light," revealing that the light is actually Zachariah searching for them. Zachariah's goal is to send Sam and Dean back to Earth and convince them to say 'yes' to Lucifer and Michael.

Castiel sends them on a mission to find an angel named Joshua , who resides in the center of Heaven, in Heaven's Garden. Joshua, according to Castiel, is rumored to be the angel that God speaks to, and their only chance of finding God on Earth.

To find him, the brothers must follow the Road, the axis mundi, for it will lead them to Heaven's Garden. The Road weaves through Sam and Dean's memories, and they become lost and are eventually captured by Zachariah.

Joshua interrupts Zachariah with a message for Sam and Dean. He informs them that though God was the one who saved them from Lucifer and resurrected Castiel, God will not intervene to destroy Lucifer and stop the Apocalypse.

Even after Castiel tore down his wall , Sam still believes that they can reach him. Despite Dean thinking Castiel won't listen, Sam calls Castiel, and tells him they can help. Although Castiel doesn't answer right away, he comes to Sam's call and asks for help. Sam sets out with the others to help Castiel. The last moment they have together is when Castiel tells Sam where to find the blood cocktail meant to open Purgatory.

Later, Castiel is overcome by the Leviathans, and Sam watches Castiel disappear into the water. Castiel attempts to right his wrong by attempting to fix Sam's mental state, but fails.

Castiel deeply regrets what he did to Sam, and he states that he can't fix it. Then the idea hits Castiel to switch places with Sam's mental state. Castiel takes on Sam's insanity, and begins to see Lucifer.

Now sane, Sam is shocked to see Castiel alive, and becomes worried about how he's acting. Sam is a bit shocked that Dean wants to leave Castiel in the mental institution. Sam promises to help find a cure for what Castiel took on.

Castiel tells Sam that he doesn't need to fix anything and that taking on Sam's pain gave him purpose. Castiel also mentions that he doesn't see Lucifer anymore since it was Sam's own hallucination. Sam is sad to hear Castiel doesn't think that he's broken. Sam inquired about what happened to Castiel in Purgatory , but got no answer from Dean. Sam is excited to see Castiel's return and he has regained his sanity. Sam is less suspicious of Castiel than Dean. When Castiel brings himself and Sam into the mind of Fred Jones, Castiel can relate to Sam, as he too, has been running from his problems, and makes a decision to return to Heaven, but is shot down by Naomi.

In Clip Show , when Castiel's relationship with Dean is strained due to Dean's anger over Castiel's lack of trust in him, Sam comforts Castiel, trying to convince him that Dean just needs time. He also gives Dean his approval of Ezekiel helping, saying Ezekiel is a good soldier and indicating they are friends. Afterwards, Castiel is excited by the idea of Sam and Dean being his guides to being human, but Dean is forced to ask him to leave to save Sam who "Ezekiel" threatens to leave and let Sam die if Castiel doesn't go.

However, this time, Dean partially explains why to Castiel who continues investigating on his own. After learning from Malachi that Ezekiel is dead, Castiel escapes and calls Dean to warn him that the angel who helped Sam isn't really Ezekiel.

Unfortunately, his warning comes too late. In " Road Trip ", after the angel possessing Sam kills Kevin and takes off, Castiel comes to aid Dean with saving him. While Dean is originally going to kill Sam to kill the angel, Castiel presents the solution of going to Crowley for help to get him to do what he did with Samandriel to bring out Sam and get him to expel the angel.

After finding "Sam", Castiel knocks him out and watches as Crowley tortures the angel to get information, admitting to Dean that its not easy for him to watch. He is also able to confirm that the angel did in fact heal most of the damage to Sam's body from the Trials.

Castiel is furious to learn that the angel is actually Gadreel , the angel that allowed evil into the Garden of Eden and thus started all of the chaos on Earth. Dean eventually asks Castiel to possess Sam to help him force Gadreel out, but Castiel can't do that as he needs Sam's permission.

While waiting to see if it will work, Castiel reassures Dean. Finally, with Crowley's help, Sam expels Gadreel and Castiel heals the wounds he got from the torture, promising to finish Gadreel's healing of him though it will take time.

When Dean leaves, Castiel stays with Sam. In " First Born ," Castiel stays with Sam in the bunker, trying to enjoy human things such as a sandwich but having a hard time as an angel. He also pushes him to make up with Dean. Castiel has nearly finished healing Sam and when he goes to give him his next treatment, he discovers that Sam still has some of Gadreel's grace inside him. Castiel discovers that they can use the residual grace to track Gadreel from the Men of Letters files and painfully starts extracting the grace from Sam.

Castiel soon discovers that losing the grace is causing Sam to start to revert to the state he was in before Gadreel possessed him, but Sam insists they keep going as he wants to make up for his past which Castiel reluctantly agrees to. Eventually Sam's condition deteriorates badly and Castiel chooses to finish healing him completely, destroying the rest of the grace rather than sacrifice Sam even though they might not have enough grace for the spell. Castiel explains that being human has taught him that he was wrong in the past about doing whatever it takes to achieve what he wants and that he empathizes with Sam as he is the only one who has screwed up more times than Sam has.

With this, Castiel officially loses any remaining disgust he holds towards Sam and his nature. After the spell fails, an appreciative Sam gives a stunned Castiel a hug and he returns it. Following the defeat of Metatron, Castiel begins gathering rogue angels.

Sam eventually calls to tell him that Dean is a demon, much to Castiel's discomfort. After Crowley provides Castiel with extra grace, Castiel rushes to the bunker to rescue Sam from a murderous Dean Winchester. The two keep this mission a secret, and go as far as to recruit the help of Bobby Singer, Charlie, and Rowena.

Castiel goes to Heaven to meet Bobby and retrieve Metatron, who is believed to know a cure for the Mark. Upon his return, Castiel delivers a letter from Bobby to Sam. When Rowena and Charlie are asked to help, Castiel is tasked with guarding the witch to ensure Charlie is comfortable. Afterwards Sam is later happy to see Castiel regain his own grace and both agree on not telling Dean how they did it. Sam even defends Cass' possession of Claire's father , since that helped saved the world.

Sam and Castiel are united in benching Dean from the case, due to his uncontrollable nature with the mark. During the case, Sam informs Castiel of the long thought extinct Grigori who kidnapped Claire's mother and kills her later.

They work together in fighting him but watch Claire kill Tamiel instead. They soon succeed in removing the Mark of Dean but at the cost of freeing The Darkness. Some time after The Darkness was released, Sam is reunited with a sick Castiel and helps the angel search for his "crappy" car. When the spell cast upon Castiel takes over, Sam is the one to point a gun at Rowena's head to make her undo the spell. When Sam ends up trapped inside a cage with Lucifer in " The Devil in the Details ", both Castiel and Dean rush to help him fend off the archangel.

All three seemingly escape unchanged. Sam offers the use of his soul to power a spell that can remove the warding's on the submarine, but Sam soon discovers that "Castiel" is in fact Lucifer. Lucifer takes Sam upon his offer and proceeds to penetrate his chest, causing Sam immense pain.

Before Lucifer can do any serious damage, Castiel uses every ounce of his strength to regain control of his vessel and save Sam. Although Castiel is forced to surrender control back to Lucifer so the archangel can rescue Dean, Castiel was able to keep Sam out of harm's way. However, the revelation that Castiel said "yes" convinces Sam that Castiel wants to be a vessel, and thus does not wish to be saved.

Dean persistently argues that this is not the case, and Sam, hoping his own beliefs are untrue, has assisted in every attempt made to rescue Castiel.

Sam and Castiel are reunited after a botched fight against Amara ends with Lucifer expelled from his vessel in Alpha and Omega. When Dean prepares to confront Amara in their latest plan, Castiel promises Dean that he will watch out for Sam and make sure he doesn't do anything stupid. Sam and Castiel later gather at a bar with Crowley, Rowena and God. When Dean's mission appears successful, Castiel follows Sam back to the bunker, but is suddenly banished by a blonde woman.

Castiel returns to the bunker only to find Dean and a resurrected Mary Winchester. The three decide to rescue Sam from the blonde woman. The confrontation leads to a success and Sam is brought back home in " Mamma Mia ". Knowing Lucifer is still on the loose, Castiel leaves the bunker alone to deal with the archangel, whose freedom he blames on himself. The four manage to prevent Lucifer's plan to murder a dozen human who are attending a concert he hosted under the guise of his vessel, Vince Vincente.

Lucifer escapes capture, however, the four continue hunting down the archangel as he takes on various vessels, until he reaches President Jefferson Rooney. As soon as Castiel senses it, he quickly informs Sam and Dean that Lucifer has now conceived a child.

The gang make a plan to confront Lucifer's mistress and convince her to abort the child. Ketch offers them a weapon to expel Lucifer from the President; with Rowena in tow, the gang are successful in freeing the President from possession.
