In the seventh season premiere, Castiel assumes his new role as God. Although he doesn't kill Sam, Dean and Bobby, he warns them not to interfere in his business. Taking on the mantle of the Almighty, Castiel sets out to right some of the wrongs in the world. While Sam struggles to deal with the broken mental wall in his head, Dean decides to bind Death (guest star JULIAN RICHINGS) and order him to stop Castiel. But the former angel is one step ahead of them, leaving Dean to face a very angry Death.
