Sam is once again dealing with the broken wall in his head in the upcoming episode of "Supernatural". He has difficulty determining what's real and what's not with Lucifer sticking around to convince him that what happened since Sam escaped hell is actually a lie.
Sam keeps having hallucinations and he desperately wants to end it. Amid his confusion, he points his gun at his own brother Dean. Now that Dean has to fight Leviathan while keeping an eye on Sam, Bobby worries that Dean is beginning to stumble under the weight of these two tasks.
"Hello, Cruel World" will air next Friday, September 30 at 9/8c on The CW. Misha Collins will still appear in the upcoming episode although Castiel is dead since Leviathan has taken over Castiel's body in the season 7 premiere.
