Castiel is about to reveal information to Dean when he is forcibly taken back to Heaven. His vessel Jimmy Novak was able to be an angelic vessel due to something "is in his blood". Jimmy describes being possessed by Castiel as like being "chained to a comet".

Jimmy returns to his family, but he is pursued by demons who shoot him. Castiel possess Jimmy's daughter Claire Novak, but as he lies dying Jimmy begs Castiel to use him as a vessel instead.

As Castiel leaves, Dean asks him what it was he wanted to tell him, but Castiel rebuffs him, saying he doesn't serve man...or Dean, only Heaven.
