Castiel is later found wandering naked in the woods near the water with no memory Outside of who he is by [[Daphne Allen]], who claims that God led her to him. She takes him homeLucifer, he takes on the name [[Emmanuel Allen]], and they marry. He discovers he has a gift for healing.  While searching for a way to help Sam, whose psychosis is killing him, Dean hears about Emmanuel from another hunter, and is shocked to discover it is Castiel. Castiel eventually regains his memories, and is horrified at what he did. He tries to heal Sam, but unable to do so, he chooses to take Sam's madness into his own mind.  After becoming catatonic for a time, Castiel awakes crazed but cognizant when the [[Word of God]] is uncovered, and he helps Sam and Dean identify the tablet. He later aids Dean in killing Leviathan leader [[Dick Roman]], and in the ensuing explosion is pulled into Purgatory with Dean, where Castiel disappears. A year later, when Dean escapes Purgatory, Castiel is not with him, and Dean tells Sam that Castiel "didn't make it," having "let go" in Purgatory when things "got hairy" not long before Dean escaped. Its revealed that in being in Purgatory restored Castiel's sanity and that while he helped Dean escape, he remained out of his own free will as he chose to stay in Purgatory as his penance for his sins. However, angels led by [[Naomi]] rescued him and Castiel was rescued, in a somewhat weakened state and under orders only angel that he is unaware of shown to aid the Winchesters and report into Naomi periodically. Although he eventually managed to escape Naomi's controlhave been resurrected after having been killed, he was subsequently manipulated by exiled angel [[Metatron]] into completing a ritual that banished all angels from Heaven, the same ritual concluding with Metatron taking Castiel's [[grace]] and leaving him a human. After some time forced to make a life for himself as a human, made more complicated by Dean's decision to reject Castiel to take Heaven's attention away from Sam, who was still healing from damage he sustained during the [[trials]], Castiel was able to regain his angelic status by stealing the [[grace]] from the angel [[Theo]]. Despite Metatron's attempts to paint Castiel as the villain of the piece, he is eventually able to prove to the other angels that Metatron sees them as nothing has been resurrected more than fools to be manipulated and tricked, [[Gadreel]]'s sacrifice allowing Castiel to trap Metatron in Heaven's prison. Although his stolen grace would eventually kill him, Castiel's life was saved when Crowley killed the angel [[Adina]] to transfer her grace to Castiel. After curing Dean of his transformation into a demon, Castiel briefly reunites with his former vessel [[Claire Novak]] while working to resolve the conflict in Heaven. However, he is left on the run from Heaven once again when he extracts Metatron from Heaven to question him about a cure for the [[Mark of Cain]]. Even after taking Metatron's grace to question him about a possible cure, Metatron reveals that he actually doesn't know of a cure, but agrees to show Castiel to the location where he left the fragments of Castiel's original Grace in return for his life. Although Metatron escapes with the Demon Tablet, Castiel is able to recover his grace and restore some of his power.

Angels as Castiel are absolutely unaffected by [[salt]] shotgun shots, every single kind of [[devil's traps]] and even than if [[Dean]] stabbed him into the chest and hit his heart with [[Ruby's knife]]. [[Sam]] self said "A demon who's immune to salt rounds and devil's traps... and Ruby's knife? Dean, Lilith is scared of that thing!".Castiel manifests on Earth through possession of a vessel -- in his case [[Jimmy Novak]]. On one occasion, Castiel describes his true angelic form as a "multidimensional wavelength of celestial intent" ;<ref name="six03">[[6.03 The Third Man]]</ref>; on another, he says that his true form is the size of the [http://en.wikipedia.org/wiki/Chrysler_Building Chrysler Building] in New York, which is 1047 feet (319 m) in height.<ref name="six07">[[6.07 Family Matters]]</ref>

He communicates with his vessel Jimmy through the electronics in his home<ref name="four20">[[4.20 The Rapture]]</ref>, and appears to use an analogous method to communicate with Dean and Sam in [[Heaven]].<ref name="five16">[[5.16 Dark Side of the Moon]]</ref> Castiel can also speak to his vessel unaided; he converses with Jimmy to obtain his consent to serve as a vessel.<ref name="four20">[[4.20 The Rapture]]</ref> Castiel, using his vessel, can easily overpower and kill demons, sometimes even groups of them, by touch.

After [[Angel Banishing Sigil|banishingHell Ghosts]] himself and a group of other angels, Castiel loses more of his powers and appears almost mortal at the end of season five.

As an angel, Castiel has the ability to [[resurrection|resurrect the dead]], though the strength of this ability has varied over time. By leading an incursion of angels into [[Hell]], Castiel was able to retrieve Dean's [[soul]] and then resurrect him on Earth.<ref name="four01" /> Though he lost this power along with the majority of his other abilities, Castiel regained it following his second resurrection and was able to bring [[Bobby Singer]] back simply by touching two fingers to his forehead.<ref name="five22" /> When [[Crowley]] threatened to kill the Winchesters, Castiel simply told him that he would resurrect them again if Crowley did so.<ref name="six20" /> After losing and regaining his [[grace]], Castiel's ability to resurrect the dead was severely impeded.

With Heaven failing After his second resurrection by [[God]], with enhanced abilities, he sees his decisions and support of freewill to have been affirmed. Castiel begins to show pride, while remaining somewhat naive with regard to consequences.

He intends to be an involved god, a better and loving god who will not abandon the world. He renounces his dedication to free will, though Castiel states saying that Dean has never listened when angels need a firm hand.

Castiel's superiors begin to question his loyalty and promote [[Uriel]] to oversee him. Castiel eventually rebels against and is ostracized from heaven, leaving him deprived of most of his angelic abilities, forcing him to interact more with humans than he had previously. He is often confused by the finer details of human interaction and is blind to social norms. He allies himself with Dean, and despite his despondency over the absence of his maker and their desperate situation, Castiel continues to fight against the Apocalypse.  After his second resurrection by [[God]], with enhanced abilities, he sees his decisions and support of freewill to have been affirmed. Castiel begins to show pride, while remaining somewhat naive with regard to consequences. Crowley is able manipulate this budding sense of pride to get Castiel to start the angelic civil war. Castiel becomes dedicated to his own decisions, and tends to pass over other opinions, even Dean's, in the absence of another clear course.

He is quick to smite those he feels used to be hypocritical and unjust, and rewards those who have faith. However, Castiel is being influenced by entities inside him - including leviathans - and his actions become erratic and violent. He realizes he is not strong enough to contain the power, and at a prompt either hide from Sam, he goes to the brothers for help. He is apologetic and humbled; after the souls are out of him he wants to find a way to redeem himself before the brothers. He eventually takes Sam's madness on himself, freeing Sam.  In episode [[5.14 My Bloody Valentine]], Castiel shows or nullify his deep affection towards raw meat, eating it in the room and unable powers to get to [[famine]], one of the four horsemen. Here, we realize that Castiel's vessel, [[Jimmy Novak]] is desiring the food which he cannot gain access to with the angel possessing him. Castiel's insanity after taking on Sam's memories of [[Hell]] seems to free him of some of his guilt, though it leaves his mind scattered. He was unwilling to fight due to his belief that he is a "jinx," though Dean convinces him to help kill [[Dick Roman]]. He also expresses some fondness for [[Meg]] despite the previous animosity that existed between them. However, after getting trapped in [[Purgatory]], Castiel seemed to have regained his sanity, though he admitted there is no way to know for sure. However, his experiences have changed his personality somewhat and he is no longer as aloof as he usually is and has displayed a fondness for human things he took for granted such as watching television, which he never understood beforevarying degrees.

While Castiel continues to press for information on the Darkness, Metatron taunts Castiel for being used by everyone he trusts, and that he was never the same even after getting his grace back. While Castiel beats Metatron bloodbloody, Metatron begs Castiel to kill him, but Castiel refuses, countering that Metatron isn't as happy being human as he'd claimed. Metatron admits that he's miserable, and Castiel admits that he's been manipulated but that he won't be any more. Finally, Metatron tells Castiel what he knows about the Darkness: that she's God's sister whom God sacrificed to make the world.

As the [[zombie]]s swarm them, Castiel fights them off with his [[angel blade]] and [[smiting]]. However, as the Winchesters and Castiel start to get overwhelmed, Castiel grabs [[Jack]]'s corpse and leads them into a nearby crypt for safety where they discuss options. As the zombies are just corpses possessed by the [[Hell Ghostsghosts]], Castiel suggests salting and burning their bodies to get rid of them, but that idea is shot down. The three are joined by the [[demon]] [[Belphegor]] who possesses Jack's corpse, much to Castiel's disgust and ignores Castiel's orders to get out of Jack. Belphegor insists that he can help them as he wants [[Hell]] returned to normal and Castiel reluctantly gives the demon some of his blood for a [[spell ]] to eject the souls [[soul]]s from the corpses they are possessing.

After escaping the cemetery, the group finds the aftermath of an attack by the escaped ghost of [[Constance Welch]] and Belphegor suggests a spell to create a mile-wide barrier to contain the escaped ghosts until they can find a solution to deal with them. Castiel realizes that the town of Harlan, Kansas is within that radius and the Winchesters decide to evacuate Harlan for protection of the residents. [[Dean ]] assigns Castiel to help Belphegor prepare for the spell, but Castiel refuses as he can't even look at the demon possessing the body of his surrogate son and so decides to help [[Sam ]] clear out the residents while Dean helps Belphegor instead.

:''"Even if we didn't know that all of the challenges that we face were born of Chuck's machinations, how would we describe it all? We'd call it "'life." ' Because that's precisely what life is. It's an obstacle course, and maybe Chuck designed the obstacles, but we ran our own race. We made our own moves. And mostly, we did well with that."''

With more [[Hell Ghosts]] ghosts escaping, [[Rowena]] attempts to use a spell from the ''[[Book of the Damned]]'' to strengthen the barrier. However, the spell fails as the ghosts are too strong and the barrier too weak. After the failure, [[Belphegor]] visits the rupture to [[Hell]], joined by Castiel who continues to remain suspicious of the [[demon]]'s motives. Belphegor reveals that the rupture is not a gate or [[portal]], but a tear [[God]] opened straight into Hell itself and suggests using [[Lilith's Crook]] to draw all of the souls and demons back in. Though the Crook is locked in [[Lilith's Chamber]], the Chamber was opened by God along with all of the other doors in Hell. However, Belphegor demands that Castiel accompany him into Hell as protection from the remaining demons while the Winchesters and Rowena use the [[Spells#Sanetur Acre Vulnus|Sanetur Acre Vulnus spell]] to close the rupture. Dean, without hesitation, agrees to Castiel joining the demon, much to Castiel's frustration.

Castiel confronts Belphegor who tries to convince Castiel to leave before throwing him out of Lilith's Chamber with [[telekinesis]]. Belphegor reveals that Ardat was telling the truth and Belphegor intends to use the Crook as a siphon to absorb all the souls and demons of Hell into himself to gain unlimited power. Belphegor sounds the Crook, drawing all of the souls and demons inside of it, but Castiel fights his way through the strong wind the Crook produces and beats the demon to the ground. Belphegor attempts to trick Castiel by pretending to be [[Jack]], but Castiel easily sees through it and [[smitingSmiting|smites]] Belphegor, killing him. However, Castiel's smiting burns Jack's corpse into a charred skeleton and destroys the Crook, preventing all of the souls and demons from returning. Castiel is able to climb out of the closing rupture and reveals the death of Belphegor and failure of their plan to an angry Dean. Before the argument can continue, Rowena uses the Death Is an Infinite Vessel spell to draw all of the remaining souls and demons into herself. With a final goodbye to the Winchesters and Castiel, Rowena sacrifices herself to cast Hell's denizens back where they belong before the rupture seals.

Castiel is shown to be ignoring text messages from [[Sam]]. Sam later calls Castiel and leaves him a message about the renewed threat from [[God]] and the [[resurrection]] of [[Lilith]].

After killing the djinn, Castiel dumps his body in the lake and [[healingHealing|heals]] Caleb's injured leg. However, Castiel's failing powers cause him to struggle with healing the minor injury. Though Melly questions his powers, Castiel decides that its better for her and Caleb not to ever understand what happened and thanks her for their time together. Castiel has realized that if he stays, nothing will ever change so he must return to helping people and end his vacation.

:''"DeanLet me rephrase. If you don't help me tonight, I need will find you and burn you alive."''Castiel returns to the Bunker much to Sam and [[Eileen Leahy]]'s surprise, telling the two that he is ready to help. After learning that Sam and Eileen were looking for signs of Chuck and the newly resurrected [[Lilith]], Castiel suggests that due to Sam's connection to Chuck through his wound, he had fired a piece of his soul from [[the Equalizer]], and in doing so a piece of Chuck may also be inside of Sam. In the infirmary, Sam questions if Castiel is sure of his plan. He tells Sam that while he can't heal his wound, he should be able to call me probe, to study it and see if it can lead them to Chuck. Cas holds out a glowing hand and probes the wound on Sam's shoulder. As both struggle to endure the pain, Sam tells Cas to continue. A bright light flashes, and Sam is sent flying backagainst the wall. Cas reels back as Sam is hurtfalls back to the bed, unconscious. After checking on Sam, Cas makes a call to the [[shaman]] [[Sergei]]. After reminding Sergei that he owes him for failing to help Jack, Cas resorts to threatening to burn him alive before hanging up the phone and Imaking another call. Castiel soon greets Sergei at the Bunker door, and after examining Sam the shaman tells Cas and Eileen that Sam will die.After making it worse for Sam he demands the [[Key to Death]] in exchange for saving Sam's life. Where are you?!"Castiel, however was prepared for Sergei's double cross and reveals he has had [[Bobby Singer (Apocalypse World)|Bobby]] tracking Sergei's niece, and on his word something bad would happen to her. Sergei relents and brings Sam back. Dean returns to the Bunker after having gotten Cas's messages about Sam. When he arrives, Cas assures him that Sam is okay and the two go the infirmary to check on him. There, Sam tells them that he knows Chuck is weak, and he believes that they can actually beat him.

Dean and Castiel try to contact Eileen and Sam before they travel to Purgatory to retrieve a [[leviathan Leviathan blossom]], however they soon realize that Chuck has captured them. Dean tracks Eileen's cell phone to the Lucky Elephant casino in Milford, Nebraska, but Castiel insists that they need to go to Purgatory. Dean shoots him down, but he yells at Dean for being so stupid as they don't have anything that can hurt Chuck and finishing Michael's binding spell takes priority.

Upon passing through the portal, Castiel states that he never saw a blossom during his time in Purgatory, meaning it's the only flower in the realm. They manage to capture a [[leviathanLeviathan]] and force it to reveal where they can find the blossoms, which grow out of the soil when leviathan Leviathan die. He also reveals that [[Benny]] was killed by his fellow vampires after helping Sam and Bobby out of Purgatory. While en route, Dean mourns Benny's death and Castiel remembers how he unleashed the leviathans into the world and continues to regret his past mistakes. Dean says he knows that Castiel is sorry about Belphegor and Mary's deaths, but Castiel clarifies that he is talking about Jack. He tells Dean that he already apologized but Dean refused to hear it because he was too angry to care about his friend. He left, but Dean didn't stop him.

The trio arrive at a leviathan Leviathan graveyard riddled with blossoms and skeletons. However, the area is guarded by an angel trap. The leviathan reveals that they plan to take them to Eve so she can have revenge for killing her and her alphas. After Dean gets knocked unconscious, Castiel offers to go peacefully in exchange for sparing Dean. They take the angel and destroy the blossoms. Dean wanders around Purgatory to find Castiel, but with only minutes left before the portal closes, he stops and starts praying. He admits that he should have stopped Castiel from leaving, but he didn't because venting his anger was easier than admitting that he was wrong about everything that happened when Mary and Jack died. He says he can't control his anger when it comes out, no matter how much he wants to. He tells Castiel that he does forgive him for everything that happened. He apologizes for taking so long to tell him and hopes he can hear him. Meanwhile, Castiel has located a leviathan blossom and manages to fight off the leviathans and escape. He makes his way to Dean in the nick of time. Dean tries to apologize face to face, but Castiel says he doesn't have to, having received his prayer.

They arrive at the Bunker and start putting the spell together, and Castiel mixes his blood into the mix as Dean cannot carry the Mark a second time. They make their way to Milford to save Sam and Eileen, but Chuck forces Eileen to attack them. They pass the orb to Sam, who, after having seen what would happen if they trap God, drops the orb and allows Chuck to crush it and heal their wounds from [[the Equalizer]]. Chuck makes His leave after Dean tells Him that they'll never give Him the ending He wants.

In the Bunker, Dean receives a call from his cell from Castiel. He tells Dean that he's hurt and asks him to let him in the Bunker. But when Dean opens the door, it's revealed that it was [[Lucifer]] imitating Castiel's voice to trick them into letting him in the Bunker.
