Season 7, Episode 2
Hello, Cruel WorldWritten by Ben Edlund.Directed by Guy Bee.Air Date: September 30, 2011.After throwing around Dean and Bobby, Castiel's vessel begins to break down. Dean realizes that the beasts cannot remain within Castiel's body without destroying it, and as a result, the Leviathans disperse into the local water supply nearby. Possessing different people and establishing a base at Sioux Falls General Hospital to maintain a food supply, the Leviathans hint at further plans, a boss, and the importance of maintaining discretion to prevent unwanted attention. Meanwhile, as Sam, Bobby, and Dean attempt to discover the Leviathans' whereabouts, Sam continues to be tortured by visions of Lucifer, slowly coming to believe that the world he sees is not reality.
