This is all of Castiel's minor relationships from throughout the series.Heaven. Castiel was shocked when he found out Balthazar had rebelled and was moonlighting as a crossroads demon.
After Balthazar rescues him from Raphael, Castiel sets him free from a ring of holy fire which enables him to escape the Winchesters. Afterwards, Balthazar assists Castiel in the war in any and every task given, including saving the Titanic (and later re-sinking it).
Their relationship becomes strained once Balthazar discovers Castiel's alliance with Crowley. Unable to stop Castiel himself, Balthazar becomes a double agent for the Winchesters and eventually betrays his old friend, by giving Sam and Dean Castiel's location.
Castiel then sees his friend as a loose end, and decides to lure Balthazar to a location under the guise of talks before stabbing him to death with an angel blade.same garrison. Castiel, for the most part, was Uriel's superior, and stopped Uriel from hurting Sam and Dean many times. Uriel had a strong dislike of human beings, calling them "mud monkeys".
Uriel went rogue and tried to convert Castiel to his own plan of helping Lucifer destroy mankind. Castiel refused, and the two sworn rivals then engaged in a bitter fight to the death. Just when it looked like Castiel was about to be defeated and killed, former angel Anna Milton came up and stabbed Uriel, killing him and saving Castiel's life.Purgatory, knowing Castiel needed the souls to win the war in Heaven, and so a secret alliance was formed.
Castiel helped collect creatures for Crowley to experiment upon, while Crowley gave 50,000 souls from Hell in advance. Eventually, Castiel betrayed Crowley and opened the door to Purgatory himself. Thus, their working relationship ended.
Castiel later declared himself the new God, and killed Raphael before deciding to spare Crowley, saying that he had plans for him. Those plans were that Castiel would control the flow of souls going into Hell, and that Crowley could continue to rule there.
When Crowley encountered the insane Castiel, he was furious to find him still alive, and also angry that the Winchesters were harboring him. However, Crowley left him alone for the time being, stating that it would be no fun to kill him in his crazy state. He asked Sam and Dean to call him when Castiel regained his sanity so they could fight.
At this time, Crowley respected Castiel's wishes for him not to harm Meg. This was probably due to the fact they had a common enemy to fight. The Winchesters needed Castiel, and Castiel was fond of Meg.
When Castiel returned from Purgatory, he faced off with Crowley even in his weakened state. Castiel tried to smite Crowley, terrifying the King of Hell into fleeing. Castiel managed to damage Crowley's plans by breaking The Word of God in half, causing Crowley to only get away with one half.
Crowley later captures Castiel, and shoots him in the gut using bullets made from a melted-down Angel Blade, severely injuring him. Crowley had correctly deduced that Castiel had the angel tablet inside of him, and painfully removes it through the hole his bullet made.
In his weakened state, Castiel manages to escape when Crowley leaves him with a single guard. Later, desperate to save Sam from Gadreel, Castiel works with Crowley to allow them to communicate with Sam, and have him force Gadreel out (having gotten the idea from Crowley's torture of Samandriel). As part of the efforts, Castiel had to burn off Sam's anti-possession tattoo so Crowley could possess him.
The plan to use Crowley to save Sam succeeds, and Sam expels Gadreel. Afterward, following Dean's lead, Castiel lets Crowley go as part of their deal.
During the season 10 finale, Rowena casts the Attack Dog spell on Castiel and has him attack Crowley. The demon King however, survives. They do not meet again until Castiel arrives in Hell following a confrontation with Amara. The next time Crowley sees Castiel, he is possessed by Lucifer.
In Hell's Angel, Crowley helps the Winchesters in freeing Castiel of Lucifer. Crowley enters Castiel's vessel, but finds him depressed. His efforts to get Castiel to expel Lucifer fail, and Crowley himself is soon expelled. The two are reunited and working together again after Amara expels Lucifer herself in the season 11 finale.
Castiel has never met God, but follows his orders out of faith. He was obedient until Dean began putting doubts in his head as to who was really giving the angels their orders. Castiel had always followed orders to the best of his abilities, believing them to be passed down to him from God.
Castiel eventually rebels against Heaven and helps Dean. In Season 5, he begins to look for God in order to stop Lucifer, using Dean's Amulet, but is severely disenchanted when being led to believe God simply doesn't care about the state of things anymore.
Unlike any angel, Castiel has been brought back to life many times, and he assumes that God himself has revived him. As an apparent reward for his role in averting The Apocalypse, God increases Castiel's power and upgrades him with more power. Later on, Castiel asks for God's help, but God doesn't respond.
Following this failure to get God's notice, and other previous failures, Castiel takes many souls into himself (including the Leviathans), and declares himself the new God. Power drunk but well meaning, he quite possibly becomes the greatest threat that the world has ever known.
God (apparently) resurrects Castiel after the angel dies due to being possessed by the Leviathans. Although God brings him back with his powers intact, Castiel has no memories for some reason. It becomes apparent later that his identity and memories were just buried, and he is able to regain them by vanquishing demons.
Castiel now believes that this and other resurrections are a punishment that gets worse each time, and that if he dies again, God will continue to bring him back for more punishment.
In Don't Call Me Shurley, God confirms to Metatron that he is the one who kept resurrecting Castiel. He tells Metatron "I've rebuilt Castiel more times than I can count" but adds that "look where that got me." Metatron also believes that Castiel is nevertheless God's favorite angel.
As Lucifer's vessel, Castiel becomes aware of God's return and helps in recruiting the angels for God's battle against the Darkness. He remains mostly by God's side following the battle's failure. Castiel sits relatively close to God inside the bar the team gather in while Dean goes on a mission as a ticking time bomb. He notices belatedly when God disappears from the room.
Castiel and Uriel are later assigned with the task of killing the then-human Anna. Castiel expresses regret and sorrow for having to do this. The mission fails when Anna gets her grace back and escapes them.
The next time Castiel sees her, he tells her he still has orders to destroy her, but she knows that he won't. She questions whether what he's doing is right, having Dean torture Alastair. She tries to make him doubt his orders but Castiel becomes angry and states that he is nothing like her, and tells her to leave.
Castiel later calls her back and asks her for help on what he should do. She tells him it is time for him to start thinking for himself.
Anna saves Castiel's life during the fight with Uriel by killing the rogue angel. When Anna confronts him about letting Sam out of Bobby Singer's panic room, he betrays her trust and has two angels take her away.
Anna eventually returns to Earth. She resents Castiel for turning her in. Castiel suspects Anna had rejoined the Host though she says otherwise. Castiel stands against her wish to kill Sam Winchester, going so far as to say he will kill her himself if she tries.
This is the last time they see each other before Anna is killed by Michael.Lucifer Rising, the two have been enemies. Before Castiel rebelled, it is believed Castiel probably respected Raphael due to rank. After being killed, Castiel seeks out Raphael in order to question him on God's whereabouts. Dean assist him on this task.
Their hatred for one another escalates when Raphael decides to restart the Apocalypse following its collapse, which Castiel refuses to let happen. Through a deal with Crowley, he starts a civil war in Heaven. The battle ends in Castiel's favor after he manages to trick Raphael and absorb the souls of Purgatory for himself.
He kills Raphael in a similar manner he himself was killed two years prior.
When Lucifer rebelled against Heaven, Castiel (a newly created angel at the time) remembers being terrified by the raging archangel. Despite this, Lucifer does know of Castiel and sees him as a brother. When they meet again, which is after Castiel rebelled against Heaven, Lucifer traps him in a ring of Holy Oil. Lucifer tries to persuade Castiel to work with him by listing things they have in common. He also makes it appear as if he is the victim and that his only mistake is loving God too much. Nevertheless, Castiel does not fall for this so Lucifer leaves Castiel in the circle while Meg stays to watch over him so that he doesn't manage to free himself.
The two meet again at Stull Cemetery, where Castiel banishes Michael using holy oil. This enrages Lucifer, who smites Castiel as punishment. Lucifer does not re-enter Castiel's life until five years later. In order to help give Rowena time in creating the spell that will send Lucifer back to his Cage, Castiel teams up with Sam and Dean and fights against Lucifer.
However, Castiel is convinced Lucifer can stop The Darkness just as he claims, so right before Rowena is finished, he says "yes" to the archangel. Lucifer takes possession of Castiel's vessel, and once again roams the Earth.
How Castiel was treated while used as a vessel is unclear. When Lucifer attempted to kill Sam in The Vessel, Castiel fought back to keep the archangel from hurting his friend, but gave control back so Lucifer could time travel and save Dean. When Crowley enters Castiel's vessel in Hell's Angel, he finds that the angel is suffering from depression, and is likely got "hooks" inside him. Castiel tells the demon that Lucifer mostly just leaves him alone.
Lucifer remains mostly in control afterwards, though he does not seem to prevent Castiel from discovering what is going on outside, as he becomes aware of God's return and the battle God helps them devise. Lucifer allows Castiel brief control of their shared vessel when the angels choose not to listen to the archangel, in hopes they would instead listen to Castiel.
The battle ends in God's defeat. Lucifer attempts to rescue God from Amara's clutches, but is knocked aside and ripped from his vessel. Castiel wakes up shortly after, unaware of his older brother's whereabouts. He later informs Dean that he was stupid for saying "yes" and that he was only trying to help.
Castiel and BartholomewEdit
In Heaven, Castiel and Bartholomew were in the same garrison and fought together. Bartholomew was in awe of Castiel and his abilities, but after the fall of the angels, sent other angels and rogue Reapers to hunt Castiel down. With the help of a warding tattoo and Sam and Dean, Castiel managed to avoid Bartholomew's attacks, but was later captured by his followers. To Castiel's surprise, Bartholomew greeted him warmly, even hugging him, having apparently put aside his former anger at Castiel. Bartholomew offers Castiel the chance to help organize the angels under his rule and retake Heaven, believing that together they can do it. Bartholomew also offers Castiel the resources to track down Metatron.
However, when Bartholomew tortures an angel and refuses to stop killing even innocent peaceful angels, Castiel refuses to help him, declaring that he wants no more part of slaughtering angels. When Bartholomew attacks him, Castiel is able to overpower his former friend but refuses to kill him. However, when Bartholomew attacks him while his back is turned, Castiel is forced to kill him in self-defense. In the aftermath, Castiel's unwillingness to kill and wanting to do things a different way causes some of Bartholomew's followers to see that there is a different way and decide to follow Castiel instead.
Castiel meets the angel Hannah after the angels were banished by Metatron's spell, and lured to a location by a noise. Hannah was the sole survivor of a group of angels who refused to join Metatron's side, the rest were killed by Gadreel. Hannah initially attempts to kill Castiel, but is defeated and begins joining his side.
When Castiel decides to build his army, Hannah acts as his second-in-command. This alliance is shattered when Metatron tricks the angels into losing faith in Castiel, blaming him for the suicide bombing. Hannah does not rejoin Castiel's side until Gadreel sacrifices himself, proving Castiel's cause to be just. Together they are able to overthrow Metatron and re-take Heaven.
Hannah later assists Castiel in gathering rogue angels. Hannah shows concern for Castiel's dwindling grace, but is repeatedly brushed off. An encounter with the husband of Hannah's vessel convinces Hannah to abandon her vessel and return to Heaven, leaving Castiel to continue the search alone, but also inspire Castiel to find his own vessel's family.
Castiel meets Hannah again in a new vessel when Castiel attempts to break Metatron out of prison. Hannah is unsupportive of this plan, but ultimately fails to stop her friend due to Bobby's assistance from the inside. Castiel meets Hannah for the last time following the rise of the Darkness. Hannah partakes in interrogating Castiel on Metatron's whereabouts, but soon chooses to believe that he doesn't know. Enraged, Efram kills Hannah. Castiel is left deeply saddened by her death.
Castiel and Claire Novak Edit
Claire's father Jimmy Novak is the chosen vessel of Castiel. Shortly after Dean was rescued from Hell, Castiel communicated with Jimmy and promised his family safety in exchange for possession. Jimmy agreed. Claire came outside the house just after Castiel entered Jimmy, and was coldly informed that he was not her father. Claire watched Castiel walk away, taking her father with him.
Claire was briefly reunited with her father when Castiel was forcibly removed from his vessel, as shown in The Rapture. When demons attack the family, Jimmy pleads to Castiel to help save them. While Claire is tied up, she is approached by Castiel (presumably in a dream) and asked to assent to possession. Claire agrees, and Castiel defeats some of the demons while possessing her.
Castiel intends to keep using Claire in order to spare Jimmy of the torment of being a vessel, but Jimmy refuses. Castiel accepts Jimmy's decision and returns to his former vessel, leaving Claire and allowing her to return to her mother.
Life for Claire becomes difficult after that. Her mother Amelia goes in search for her husband, leaving Claire mostly in the care of other people or places. She becomes rebellious and rather angry at Castiel. The two do not meet again until a couple of years later, after Hannah inspires Castiel to go check on the Novaks, only to find what a mess they are in.
Claire is initially hostile, but does admit Castiel has become a slightly better person. Castiel is shown to be protective over Claire. He gets Dean and Sam to help Claire search for her mother, leading to a confrontation with Tamiel and Amelia's subsequent death.
Despite not getting her mother back, Claire accepts Castiel, and before departing to go live with Jody Mills, she hugs him goodbye. She takes with her a birthday gift from Castiel, which is a Grumpy Cat toy. She is shown to still have it in Don't You Forget About Me.
