Uriel

Uriel is an angel who is part of Anna and Castiel's Garrsion, particularly Castiel's partner. Castiel describes Uriel as a specialist. He shows much disdain for humanity, comparing them to monkeys and larva, due to him seeing them as God's favorites over angels. Unlike his partner, he has no patience and seems to be willing to sacrifice anything to stop Lilith from breaking the 66 Seals. According to Castiel, Uriel is the funniest angel in their garrison. It is later revealed that he's a double agent and is actually a follower of Lucifer. Regardless of his loyalty to Lucifer, it seems that Uriel is also disgusted by demons to almost the same degree as he feels for humanity.

Season 4
In "It's the Great Pumpkin, Sam Winchester", Uriel is first seen with Castiel in the Winchester brothers' motel room on Halloween. They inform the brothers that they know about the witch that's trying to summon Samhain. Castiel also tell the brothers that the witch knows who they are, revealing that he and Uriel found a hex bag in the wall of their room. Castiel then tells the brothers to leave the city because they are going to destroy it and obliterate the witch with it to prevent Samhain from being summoned. This will also prevent another one of the 66 Seals from being broken. Sam and Dean protest, fearing for the citizens. Uriel is willing to kill them anyway and says that this wasn't the first time he's had to "purify" a town. He merely laughs at Sam's statement about how they couldn't do this because they were angels and are supposed to be righteous. Dean tells him to go ahead and do it, but they're staying. Uriel states that he has no problem destroying them, but Dean reminds him that he must be important if "The Man Upstairs" gave orders to bring him back to life. Uriel tells him that he will drag him out. As Dean tells Castiel to trust him and Sam to stop the summoning, Uriel begins to protest but is silenced by Castiel. Castiel tells Dean for them to work fast then the brothers leave the two angels.

Later, Uriel and Castiel are seen in a park talking. Castiel tells him that the decision has been made, but Uriel remarks that the decision was made by a "mud-monkey". When Castiel objects to his insults, Uriel replies that humans are nothing but savages. Castiel warns Uriel that he is close to blasphemy, and that Dean was saved for a reason and that he has potential. Uriel then suggests that they drag Dean out of the town by force and then destroy the city as they planned. He is put into his place when Castiel reminds him about their true orders and asks him if he's willing to disobey.

The day after Halloween and Samhain is sent back to hell by Sam, Uriel pays a visit to Sam. He makes a note about how tomorrow, November 2, is the anniversary of the murders of his mother and girlfriend. He then questions how Sam could still use the powers that Azazel gave him and reminds him that he was told not to use his powers. Sam replies that his powers saved him, Dean, and everyone else in the town and that without them he and everyone else would be dead. Uriel tells Sam that this is his second warning. He then threatens Sam and tells him the only reason he is still alive is because he's proven to be useful, but the moment that ceases to be true and he hears the word he will turn Sam into dust. Just before he leaves, Uriel tells Sam to tell Dean "to get off that high horse of his" and ask his brother what he remembers from his time in Hell.

In "I Know What You Did Last Summer", right after Sam tells Anna Milton that her parents were killed by demons, she senses that something is coming towards them. After the brothers hide Anna, Dean, Sam, and Ruby prepare for what they believe are demons. They are surprised to see that what Anna sensed are Uriel and Castiel. Uriel asks the brothers why they are in the company of a demon. Then Castiel tells them that they are here for Anna. When the brothers ask if they're here to help, Uriel tells them to be silent and commands them to give her to them. Castiel answers the brothers telling them that they're here to kill her.

In "Heaven and Hell", the two brothers refuse to give up Anna. They fight the angels, but the brothers are easily defeated. They are rescued by Anna, who banishes the angels using a blood seal. Then, the boys lead Anna to Bobby's panic room, which can repel most supernatural beings. Later, Uriel confronts Dean in his dreams while he is sleeping. Dean asks him where Castiel is and Uriel tells him that he's not here and that Castiel has a weakness: he actually cares for Dean. Uriel then demands that Anna be given to him. Dean tries to bluff and states that Anna has regained her grace and became an angel once again. Uriel then reveals that he has her grace around his neck. Uriel questions why Dean is even involving himself in this situation since she isn't even human, making it angel business. He then deduces that Dean and Anna slept together and that's why he is so committed to saving her. Uriel then threatens Dean to give Anna to him or he'll throw him back into Hell. Dean tells him to go ahead and Uriel realizes that he isn't bluffing and that he's "crazy" enough to go back to Hell. When Dean states that he won't break easily, Uriel retorts and says he will and that you just need to know where to apply the right pressure.

Waiting to regroup with Ruby, the brothers and Anna are confronted by Uriel and Castiel. When Sam questions how they found them, Anna deduces that Dean sold them out after Uriel threatened to kill Sam if he didn't. Just as Anna surrenders herself to the two angels, they are interrupted by Alastair, Ruby, and two other demons. Uriel easily deals with the other two demons, while Castiel takes on Alastair. He uses his exorcism touch to defeat both demons, but as he is exorcising the second demon, Anna is able to steal back her grace and regain it. As Anna regains her grace and becomes an angel once again, her body is destroyed and she disappears in bright, white light that seemingly destroys Alastair. Uriel is about to attack Dean for his interference, but stopped by Castiel and the two angels vanish.

In "On the Head of a Pin", Uriel and Castiel appear before the Winchester brothers in their motel room. They reveal to them that angels in their garrison are being killed. Dean tells them that they have Alastair and that he should be able tell them who's killing the angels. Uriel reveals that they're here to have Dean, Alastair's former apprentice, interrogate Alastair for information. Dean refuses, but Uriel tells him that this isn't a request. He, Dean, and Castiel teleport to the warehouse where Alastair is being held by a devil's trap. When Dean refuses again and attempts to leave, Uriel stops him by teleporting in front of him. When Dean demands to speak to Castiel alone, Uriel tells Castiel that he'll go and seek revelation to see if there are any further orders for them before he teleports away.

Castiel meets up with Uriel after Alastair is killed by Sam. Castiel realizes that demons aren't behind the angel killings, and Uriel tells him that he has received a revelation. Their superiors no longer want them to hunt the demon that's killing angels. Castiel tells Uriel that demons aren't responsible for the murders of their kin and that its possible that the garrison is being punished for losing the war and that this is the will of Heaven. Uriel questions if their Father would really do this. Castiel then states that maybe these orders aren't from God and that something is wrong in Heaven. Uriel then says that he will not just wait for death and teleports away.

Later, Castiel calls Uriel to meet him in the room Alastair was being held. Uriel asks Castiel if he will join him and help him fight whatever is killing the angels. Castiel questions how a leaky pipe could undo the work of angels and break the devil's trap he created. Uriel reasons that they underestimated Alastair's power, but Castiel claims that no demon could overpower the devil's trap. Castiel then tells Uriel, out of respect for their brotherhood, to tell him the truth. Uriel responds by saying that the only thing that can kill an angel is another angel as he pulls out an angelic blade.

Uriel admits that he freed Alastair and that he was supposed to kill Dean and escape so the blame for the angel murders could still be placed on the demons. He then reveals that he is a double agent working to free Lucifer. Uriel explains to Castiel that God stopped being their Father after he created humanity, his favorites, and that he should believe in Lucifer since he didn't bow down to humanity and stood up for the angels. He reveals to Castiel that he's been killing the members in their garrison who refused to join him, but some have joined him. He then asks Castiel to join him and help bring about the Apocalypse. Castiel refuses and the two engage in combat using their super-strength. Even when Uriel gains the upper hand, Castiel claims that he can't win because he still serves God. While punching him, Uriel replies, "You haven't even met the man. There is no will. No wrath. No God". Just before Uriel can land a final blow, he is stabbed through the neck with his angelic blade by Anna. Uriel falls to the ground and dies releasing a bright, white light. His vessel's corpse is on the ground with angel wings burned on the ground underneath it.

Season 5
In "The Song Remains the Same", after her first attempt to kill John and Mary Winchester failed Anna Milton calls upon the Uriel of 1978. Uriel appears before Anna in a younger vessel, most likely this vessel was his human host of the 21st century during 1978 or a blood relative of his 21st century human host. He immediately asks Anna why she called him and that she knows that "they", most likely referring to their superiors, don't like it when they're down on Earth. After a few moments, Uriel realizes that Anna was not from 1978 and confronts her about it. Anna admits that she is from the future. She lies to Uriel that the Winchester family, who she's after, will kill him in the future and that she's giving him a chance to not let that happen. Uriel then thanks her.

Later, when the two angels find the Winchesters, they remove all the defenses they've set up, smearing the blood seals and removing holy oil traps. Then the angels disorient the Winchesters with a high-pitched tone, breaking the windows and turning off the house's power. Uriel then walks in through the front door. Dean asks him who he is and is displeased when he introduces himself as Uriel. Uriel fights Dean, while Anna takes care of Sam, John, and Mary. Uriel easily overpowers Dean beating him to a pulp. Uriel then grabs him by the throat and makes him watch as Anna kills Sam. After he sees Michael save Mary and kill Anna, he lets go and apologizes to Michael. He tells Michael that he didn't know, most likely referring to the fact that he didn't know Dean was his true vessel. Michael responds, "Goodbye, Uriel," and snaps his fingers teleporting Uriel away.
