he himself. Together with Bobby, the Winchester brothers find a psychic, Pamela
Barnes, to help them discover what pulled Dean out of Hell. Pamela does find
out the name of the being, Castiel, but at a horrible price—the sight
of Castiel burns her eyes out. It is also revealed that Sam's psychic abilities
have advanced greatly as he now is able to exorcise demons. He also seems
to be frequently meeting with Ruby, who has possessed a new host. Sick of
being toyed with, Dean decides to summon the thing together with Bobby in
order to find out what it wants and prepares a ritual. The ritual succeeds
