Castiel's vessel wades into the reservoir and, as they watch, disappears beneath the surface. A vortex then erupts outwards and spreads a black ooze throughout the water which vanishes moments later. Bobby remarks that, now that they're in the pipes, the Leviathans will be able to travel anywhere. Dean finds [[Castiel's Trench Coat]] floating in the water, but there is no other sign of the angel's vessel; the hunters assume that he has been destroyed by the Leviathans. Dean takes the trench coat with him as they leave the reservoir. Later Bobby tries to get Dean to talk about how he is coping with Castiel's death, along with everything else, but Dean refuses to talk.

Dean is trying to find help for Sam, who has been hospitalized due to a psychotics episode. It has been bought on by his hallucinations of his time in hell with Lucifer, caused after Castiel bought down the protective barrier in his mind installed by [[Death]]. While searing for help, Dean speaks to a hunter called [[Mackey]].
Dean travels to Colorado, and finds Daphne being held captive by a demon, which he kills. "Emmanuel" returns home, and to Dean's shock appears to be Castiel, although he gives no sign of recognising Dean. Emmanuel can see the demon's true face, and is shocked when Dean tells him demons walk the Earth. He agrees to go with Dean, and see if he can help Sam.
During the drive to the [[Northern Indiana State Hospital]] Emmanuel reveals he has no memories of his life before a few months ago. One day when out hiking, Daphne found him wet and naked, with no memory of who he was. She claimed that God led her to him and took him home. Using the site aouncingbaynamesbouncingbaynames.com she helped him choose the name Emmanuel. They later married, and she supports his work as a healer.
Dean says that Sam's state is due to something done by a person called "Cas", a name which provokes no response in Emmanuel. Dean reveals that he has been able to get over what was done. Emmanuel reminds Dean that "You are not a machine."
When they arrive at [[Northern Indiana State Hospital]], it is surrounded by demons. Meg takes dean aside - she wants to tell Emmanuel who he really is, so he can kill the demons, but Dean warns they don't know how he will react. However , Emmanuel overhears Meg tells him he is an angel and that he and Dean used to be friends. "That sounds pleasant" he replies, but Dean counters that it isn't, that angels are violent and corrupt. Emmanuel still doesn't remember anything, but agrees to try and help.
Emanuel agrees to try killing the demons, and walks down to where they are gathered outside the hospital. As he places a hand to each one's head and kills them. his memories of his time as an angle angel come flooding back. After he has killed them all, he walks away. dean goes after him, and Castiel says he has remembered the terrible things he did - all the killing on Heaven and Earth, and that he is responsible for Sam's condition. He despairs that he can't fix what he did, but Dean counters that maybe that was why he was brought back. In response Dean goes to the trunk of his car and takes out [[Castiel's Trench Coat]] which he has carried with him all this time. Castiel enters the hospital, and saves Sam as a demon is trying to kill him. Castiel apologises for what he did to Sam, and tries to heal him, but Sam's hallucinations remain. Later, as they visit Sam in his room where he appears worse, Castiel tells Dean that Sam's mind is too damaged and that is can't be healed. He then has an idea, and proceeds to again apologize to Sam, before taking all the psychosis from Sam's mind into his own. Castiel immediately starts to hallucinate Lucifer. Sam and Dean leave Castiel in the hospital, for his own safety. Sam challenges Dean about working with Meg is a good idea, but Dean says he doesn't think they have much choice. Meanwhile, Meg meets with [[Dr Kadinsky]] and is hired as a nurse so she can, hopefully, protect Castiel.
