As I’m sure all Supernatural fans know by now, season four’s last three episodes can be summarized in three words, “Sam versus Dean.” Now the question most fans should be asking is what would make the Winchester brothers fight each other?
In Ausiello’s latest column, he guessed at the two most obvious reasons for the fight. The first is Sam’s recent journey down the dark path with his blood lust. The second might be the fallout from a death that’s supposed to occur in April.

What do you guys think would cause Sam and Dean to have a falling out?
