==Characteristics==
[[File:Castiel S8.png|thumb|right|350px|Castiel - Angel of the Lord.]]
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>

===Powers and abilities===
Castiel's powers change over time for a number of reasons, such as when he is disenfranchised by Heaven in season five and when the angels are expelled from Heaven by Metatron.
* Arcane knowledge – Castiel, like all angels possesses vast occult knowledge, ranging from lore, to spells cast in [[Enochian]], to the structure and defenses of Hell.<ref name="six07">[[6.07 Family Matters]]</ref>* [[Clairsentience]] – Castiel is able to perceive the true visages of [[angels]] and [[demons]], as well as to pierce through [[the Veil]]. He also displayed the unique ability to tell the Leviathans apart no matter what form they took. According to Meg this is due to the Leviathans briefly using him as a vessel, which allowed him to know them "better than anyone."<ref name="seven23">[[7.23 Survival of the Fittest]]</ref> He also displays the ability to sense the presence of nearby Leviathans before they become known to anyone else.<ref name="eight05">[[8.05 Blood Brother]]</ref>* [[Dreamwalking]] - – Castiel has been shown to be able to enter the dreams of humans , and has done this to communicate with Dean Winchester.* [[Healing]] - – He can heal physical and mental damage. In addition to humans, Castiel has also healed his fellow angels. However, his healing ability does not extend to more powerful entities, as he once explained to the Winchesters that angels cannot heal archangels. * Invulnerability – As an [[Mind controlangel]] - Castiel was shown to be able not affected by conventional human weapons and could withstand being shot, stabbed, and being in close proximity to manipulate the minds of Secret Service agents to forget he saw him or the Winchestersexplosions.* [[ClairsentienceMind control]] - – Castiel is was shown to be able to perceive manipulate the true visages minds of [[angels]] and [[demons]]humans, as well as forcing them to to pierce through [[the Veil]]forget what they have seen.* [[Psychic]] - He – Castiel can undertake perform what Dean refers referred to as a "[[Vulcan Mind Meld]] " in order to read thoughts. Castiel also has the ability to sense if someone is lying, however, due to the truth being situational at times, the accuracy of this ability can be in question. * [[Pyrokinesis]] * [[Prayer]] - – Castiel, like all angels, can hear the prayers of any humans, which also allows for angels to locate the person. As revealed to [[Claire Novak]], the prayer does not need to be formal, and can be simple feeling of longing or the need to talk.* [[Pyrokinesis]] – Castiel demonstrates this when he burns Crowley's "bones."<ref name="six10">[[6.10 Caged Heat]]</ref> Later, Castiel shows the ability to incinerate lesser monsters, such as the [[vampire]] [[Lenore]], by touch.* [[Resurrection]] - – As an angel, Castiel has the ability to [[resurrection|resurrect the dead]], though the strength of this ability has varied over time. So long as he has a connection to Heaven, Castiel can could resurrect the deada deceased individual. Castiel has been able to resurrect [[Dean Winchester]], [[Bobby Singer]], and [[Jack Kline]]. However, his power to resurrect the dead has had been greatly weakened since [[the Fall]]once he regained a portion of his grace. In this diminished capacity, leaving Castiel unable had greater difficulty in performing this task, as evidenced when he was only able to bring Jack back for more than a few moments without [[Lily Sunder]]'s [[Enochian]] magic to cure Jack's condition afterwards and make the resurrection permanent.* Regeneration - – Short of being stabbed in a fatal area with an [[angel blade]], Castiel has the ability to mend all wounds incurred to himself and his [[vessel]].* [[Sedation]] - – With a touch, Castiel is able could render anyone unconscious.* [[Smiting]] - He – Like all angels, Castiel is capable of unleashing powerful celestial energy allowing him to smite most living things. This can smite black-eyed demons with general easebe done through touch or the release a blast of white light from his palms that instantly kills anything that sees it.<ref name="six19">[[6. 19 Mommy Dearest]]</ref>* Super strength and endurance - – As an angel, Castiel's strength exceeds that of human and demon, having shown the ability to punch [[Uriel]] through a brick wall in the past. After the Fall, however, Castiel and all angels have shown more susceptibility to physical damage.* [[Telekinesis]]– Castiel has shown the ability to move objects and beings with a gesture.* [[Teleportation]] - As an angel– Prior to [[the Fall]], Castiel was capable able to teleport himself, and in some cases groups of people, through time and space. He could cover great distances in a matter of seconds, as shown when he believed [[Gabriel]]'s [[Horn of Gabriel|Horn of teleporting anywhere Truth]] had been discovered, and searches an entire city in existencemoments. After the Fall, Castiel, along with the rest of the angels, lost his wings and ability to travel and was forced to take up more conventional meansto get from place to place.* [[Time Traveltravel]] - – Due to the fluidity of time, Castiel is able to bend it on occasion, traveling backwards in time. However, the act of time travel can be strenuous on angels. After the Fall, Castiel and all other angels have lost this ability, except for archangels.* Universal communication - – As an angel, Castiel is capable of understanding any language in the world, including that of animals.
===Weaknesses===
* [[Angel blade]]s - – Can cause severe injury and death to all angels. Castiel is the only angel in creation to have been resurrected after being fatally stabbed with an angel blade.* [[Archangels]] - – Archangels can overpower and [[smitingSmiting|smite]] lower angels. Castielhas been killed by archangels three times.* Higher demons - [[Demons]] – [[White-eyed Demons]] and [[Princes of Hell]] can had shown the ability to overpower Castiel, and in one instance with [[Alastair]] nullify his powers. * [[Holy fire]] - – Like all angels, Castiel is incapable of crossing holy fire, which has the ability to kill him.* [[Lance of Michael]] - – Forged by [[Michael ]] to kill [[Lucifer]], being pierced with the lance will lead to an angel dying a drawn-out and agonizing death.* [[Spells]] - – Castiel reveals once revealed to [[Meg ]] that a book with the proper [[spells ]] could theoretically kill him.* [[Warding sigils]] - – Like all angels, Castiel is susceptible to strong warding. ===Personality===Because he was an angel, Castiel initially expressed almost no emotion towards humans, and had little room for disobedience or feelings, as he was driven to follow his orders, although he does reveal some doubts about the morality of his orders, expressing an appreciation for the beauty of humans as God's creations.<ref name="four07">[[4.07 It's the Great Pumpkin, Sam Winchester]]</ref> As he spends more time with Dean, he develops empathy and affection for him, and eventually for those close to him, and humans in general. 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 eventually double-crosses Crowley, taking in the souls of Purgatory alone. He then insists on worship from his former friends. He intends to which can be an involved god, a better and loving god who will not abandon the world. He renounces his dedication to free will, saying that angels need a firm hand. 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.
==Episodes==
===[[9.14 Captives]]===
:''"No. Angels fighting angels has to stop somewhere. Might as well stop with me."''
In Castiel’s attempt to track down [[Metatron]], he learns of a faction of angels who wanted to live peacefully led by an angel named Rebecca; however they were all killed by Bartholomew. Castiel later is captured and taken to HQ where he meets Bartholomew,who is happy to see Castiel; he tells him he aims to find [[Metatron]] and restore angels to heaven and tries to make Castiel join his side.[[ Bartholomew]] then tortures an angel for information and asks Castiel to kill him, saying that he needs proof that Castiel can do what has to be done. When Castiel refuses, Bartholomew tries to attack him; Castiel easily overpowers him but doesn’t kill him. [[Bartholomew]] however lunges for Castiel again, and Castiel is forced to kill him. Later Castiel is standing at Rebecca’s grave, where one of Bartholomew’s henchmen approaches and tells him that he and other angels are willing to join Castiel.
===[[9.18 Meta Fiction]]===
He finds Metatron filming a dying man, and while Metatron cheerfully explains that he can't help, Castiel arrives and heals the man instead. He confronts Metatron and tosses the camera away, then leads Metatron to a nearby warehouse so that the police can take care of the victim in the alley. They argue over Castiel and Metatron's choices when they'd both had to live as humans without their grace. Castiel dismisses it, saying he's here for something else. Metatron assumes it's the demon tablet when Castiel reveals that he already has it. Instead, he physically shoves Metatron while questioning him on information about the Darkness, and Metatron fires back that Castiel, these days, is too afraid to hit him. Castiel punches him in response and answers, "It's not fear."
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.
Later, Sam, Dean, and Castiel have all returned to the bunker and are discuss Metatron and Amara. Dean gives Castiel a hard time about letting Metatron go, but Castiel assures him that Metatron as a human is not a threat. Castiel then counters by asking Dean why he couldn't land a hit on Amara. Dean insists that she overpowered him, but Castiel and Sam look unconvinced.
===[[15.01 Back and to the Future]]===
:''"Dean, I can't. I-I... I can't even look at him."''
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.
Armed with a shotgun loaded with rock [[salt]], Castiel joins Sam in clearing out the houses. Castiel arrives in time to save Sam from the ghost of [[serial killer]] [[John Wayne Gacy]] and [[healing|heals]] Sam's wound from the ghost. However, Castiel proves to be unable to heal Sam's wound from [[the Equalizer]], getting [[Chuck's Endings|a disturbing vision]] when he tries and sensing a strange energy that he has never felt before from the wound. Sam and Castiel rescue a mother and daughter from Gacy's ghost, but have to fight off Gacy, [[Mary Worthington]] and two other Hell Ghosts to escape. Though he is briefly overpowered, Castiel manages to recover his shotgun and save Sam. With Belphegor succeeding in establishing the barrier, the group manages to escape to the other side, leaving the Hell Ghosts trapped within.
===[[15.02 Raising Hell]]===
:''"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."''
===[[15.03 The Rupture]]===
:''"Jack's dead. Chuck's gone. You and Sam have each other. I think it's time for me to move on."''
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.
After shoving Belphegor into the rupture, Castiel jumps in after the demon and travels through Hell with him. Castiel's suspicions of Belphegor continue to grow as he learns that Hell has been emptied out of demons which Belphegor already knew and thus didn't need Castiel's protection. Belphegor claims that he just wanted company and notes the strained relationship between Dean and Castiel. In Lilith's Chamber, the two find the demon Malfayan raiding [[Lilith]]'s treasures and Castiel kills the demon after its confirmed that he doesn't have the Crook. Belphegor leads Castiel to a box sealed with an [[Enochian]] prayer to [[Lucifer]] which contains the Crook and Castiel realizes that Belphegor actually needed his help to open the box. Much to Castiel's discomfort, he is forced to sing the prayer to open the box, only to have [[Ardat]] attack them. Ardat reveals to Castiel that Belphegor is actually seeking to become King of Hell before Belphegor kills her with an [[angel blade]].
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.
In the aftermath, with Rowena's death compounded by the news of [[Ketch]]'s murder, Dean erupts into an argument with Castiel over his actions, blaming everything going wrong on the angel. Castiel insists that Belphegor was too great of a threat and had to be stopped, but Dean states that they could've dealt with him afterwards. Castiel realizes that Dean still blames him for the death of [[Mary Winchester]] and that he is as good as dead in Dean's eyes. Castiel reveals to Dean that his powers are failing which he has been trying to tell Dean for some time, though Dean has always refused to listen. With Jack dead and Chuck gone, Castiel decides that its time for him to move on and leaves the bunker.
===[[15.05 Proverbs 17:3]]===
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]].
===[[15.06 Golden Time]]===
As Castiel begins his search for the monster, which he suspects to be a [[djinn]], he is joined by [[Melly Krakowski]] whose son [[Caleb Krakowski|Caleb]] has gone missing. Melly leads Castiel towards an abandoned mine that he suspects may be the djinn's lair while he tries to warn her about what they might find while shielding her from the truth at the same time. The two locate Caleb who had escaped the monster who proves to be Sheriff Roy. The djinn tries to shoot Castiel dead, but his angel powers leave him unharmed and his wounds heal right in front of the stunned humans and monster. Knocking Sheriff Roy to the ground, Castiel brutally kills the djinn with several stabs from his [[angel blade]].
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.
===[[15.07 Last Call]]===
:''"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.
===[[15.08 Our Father, Who Aren't in Heaven]]===
===[[15.09 The Trap]]===
:''"You didn't give me a choice. You couldn't forgive me. And you couldn't move on. You were too angry. I left, but you didn't stop me."''
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.
At the Bunker, Sam explains why he couldn't trap Chuck, and Dean says it's good enough for him. Castiel says that Chuck may be gone, but He'll be back.

:''"I know. I know how you see yourself, Dean. You see yourself the same way our enemies see you. You're destructive and you're angry and you're broken. You're -- You're "Daddy's Blunt Instrument." And you think that hate and anger that's -- that's what drives you. That's who you are. It's not. And everyone who knows you sees it. Everything you have ever done, the good and the bad you have done for love. You raised your little brother for love. You fought for this whole world for love. That is who you are. You're the most caring man on Earth. You are the most selfless, loving human being I will ever know. You know, ever since we met, ever since I pulled you out of Hell, knowing you has changed me. Because you cared, I cared. I cared about you. I cared about Sam. I cared about Jack. I cared about the whole world because of you. You changed me, Dean."''

When Dean meets up with Sam and Jack, he is forced to tell them that Castiel summoned the [[Cosmic Entity]], which absorbed him into [[the Empty]] along with [[Billie]]. Jack is particularly distressed by Castiel's death, calling out to him while Sam and Dean investigate the bar.
In the Bunker, Dean receives a call from 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.
