Castiel's Relationships

This is all Castiel's minor relationships he encounters through his life and time on earth. Though by Season 6, Castiel has severed most of his relationships, presumbly as a result of his quest to stop the civil war raging in Heaven. Now that he has become God, it is not known if Castiel's former relationships have been damaged beyond repair due to his actions or if there's any hope of fixing them.

Castiel and Zachariah
Zachariah is described as Castiel's superior, in other words his teacher, and thus is forced to respect him, holding the up most respect. However, after Castiel is resurrected the first time, this respect goes away and Castiel stands up to him and scares him off to save Sam and Dean. He later aids Sam and Dean in rescuing Adam Milligan from Zachariah, only worried about the fact that he will be unable to defeat the more-powerful Zachariah and five other angels, but coming up with a way around that. Castiel essentialy sacrifices his powers to give Sam and Dean a shot at Zachariah, allowing Dean to finally kill him.

Castiel and Balthazar
They were old friends from heaven. Castiel was shocked to hear when he found out Balthazar had rebelled and was moonlighting as a crossroads demon.

Although, Balthazar did help Castiel and aided him in the civil war in heaven, Balthazar was now under Castiel's command.

However, after learning that Balthazar betrayed him and gave away his location to Sam and Dean, Castiel, knowing that his former friend had become a loose end lured Balthazar to a place under the guise of talks before sneaking up behind the other angel and hitting him in the chest with an angel sword. This resulted in Balthazar's death and it's presumed that Castiel felt some guilt over killing his former friend.

Castiel and Uriel
They were co-workers on earth while the angels were "protecting" the 66 seals. Castiel for the most part was Uriel's surperior, and stopped Uriel from hurting Sam and Dean many times as Uriel had a strong dislike of human beings, calling them "mud monkeys".

Although Uriel went rogue and tried to convert Castiel to his own plan of helping Lucifer destory mankind. Castiel refused and the two sworn rivals then engaged in a bitter fight to the death. However just when it looked Castiel was going to die, former angel Anna Milton came up and stabbed Uriel, killing the older angel and saving Castiel's life.

Castiel and Crowley
At first the two were brief allies who'd formed a partnership to stop the apocalypse but then Crowley offered to a deal to open Purgatory. Castiel needed the souls to win the war, so he secretly began working with Crowley. He even went so far as faking Crowley's death.

Castiel did help collect creatures for Crowley. Eventually, Castiel betrayed Crowley and opened the door himself. Thus their working relationship was nullified as a result of this. Castiel later re-emerged, declaring himself the new God and killed Raphael before deciding to spare Crowley, saying that he has plans for him. When Crowley reunited with the now-insane Castiel, he was furious that Castiel was still alive and that the Winchesters were harboring him as Castiel had tried to enslave him. However, realizing that Castiel was insane, Crowley left him alone for the time being, stating that it would be no fun to kill him in his crazy state where he refused to fight and asking for Sam and Dean to call him when Castiel regained his sanity so they could fight. However, Crowley respected Castiel's wishes for him not to harm Meg at the same time as the Winchesters needed Castiel and Castiel was fond of Meg, though he later captured her once she was out of Castiel's sight.

Castiel and God
Castiel has never met God, but follows his orders. He was a good little angel until Dean began putting doubts in his head. Castiel eventually rebels against heaven (and God) and helps Dean. In season 5, he begins to look for God in order to stop Lucifer using Dean's Amulet, but is let down when he finds out that God doesn't care.

Unlike any angel, Castiel has been brought back by God, twice. Later on Castiel asks for God's help, but God doesn't respond. Following that, Castiel later proclaims himself to be the new god, thus severing their connection and possibly becoming the greatest threat that the world has ever known.

Castiel and Anna
Castiel and Anna's relationship goes back thousands of years. They served together in heaven in the same Garrison. They were probaly close as Castiel states "we have history together". After Anna falls, Castiel and Uriel are the ones who are asigned to bring her in. Castiel says he is sorry but he will kill her because orders are orders. However, Anna gains her grace back and escapes. The next time he sees her he tells her he has orders to destroy her, but she knows that he won't. She calls him by his nickname Cas and questions whether what he is doing is right. She wants to work together with him but he becomes angry and states that he is nothing like her, and tells her to leave. Later, he calls her back and asks her for help on what he should do. She tells him its time for him to start thinking for himself. Anna later saves his life during the fight with Uriel and kills Uriel to save Castiel. When Anna confronts him about letting Sam out of the Panic Room he betrays her trust and has two angels take her away. She eventually escapes and is angry at Castiel for turning her in. She wants to kill Sam but Castiel tells her that if she tries he will kill her, despite what they have been through together. This is the last time they see each other before Anna is killed by Michael.

Raphael
Ever since Raphael killed Castiel in Lucifer Rising, the two have been enemies. Before Castiel rebelled, it is believed Castiel probably respected Raphael due to rank. Although after being killed, Castiel returns and confronts Raphael on where God is. Their hatred for one another escalates when Raphael wants to restart the Apocalypse. Castiel refuses to let this happen and with a deal with Crowley, he starts a civil war in Heaven. After absorbing the souls of Purgatory, Castiel kills Raphael in a similar matter himself was killed in.
