God, that would be horrible! Doesn’t Dean ever get to be happy for crying out loud??

No. No, he doesn't.

So he becomes a slacker jerk instead? Don’t think so, Eric!

Yeah, I definitely hope it is made clear WHY Dean would turn out this way, OR it's made clear that this is the Djinn's idea of what would have happened, not necessarily what would have REALLY happened.

If it's not made clear, I'm going with the Djinn theory anyway.
