Dean: “You know what? That’s it! That is it!”
Fake Dean: “What’s wrong, Bobby?”
Dean: “I’m not Bobby, okay? You’re not Sam! You’re not Dean! What is wrong with you? Why would you choose to be these guys?”
Fake Sam: “Because we’re fans… Like you.”

Fake Dean: “Ehm…I don’t think they care. Because they’re fictional characters!”
Dean: “Oh they care! Believe me, they care a lot!”
