Okay, I keep reading all the wild speculation and it’s Hellatus, so it’s time to start something here. This is Sam’s final glare at Dean in “Swan Song.” So, is he happy, sad, indifferent, mad, what the hell does it mean?? What is Sam? Is he human, angel, demon, ghost, what do you think? Is the burning out light a sign or Kripke messing with us?
So, speculate away. We’ve got all summer!
