Trivia: At the beginning, the cabin looks very similar to the cabin in The Evil Dead, even the swinging bench (although on the opposite side of the door). And the girl calls out the name Ashleu, Bruce Campbell's character in Evil Dead.
Trivia: At The End of the episode, Dean says to Sam "hey did she look familiar?" Then says "are you hungry? I could go for some pea soup." He's referring to Linda Blair in the Exorcist. She played a cop in this episode.
Answer: Over the next few episodes, it is revealed that something is not quite right with Sam - that his soul is missing since he returned from Hell, and he does not feel any emotion or attachment to his brother.
