Clark is attacked and wakes up in a mental asylum where the attending physician, Dr. Hudson, tells him he has been there for five years due to his elaborate fantasy that he has alien superpowers. In this new world, Martha is married to Lionel Luthor, Chloe is deemed insane and Lana chose Clark over Lex. Lana begs Clark to agree to Dr. Hudson's treatments so they can be together, but when a fellow patient named John, A.K.A Martian Manhunter, tells him the good doctor is actually a phantom and he needs to kill him in order to return to reality, Clark must make the toughest decision of his life.
