Yeah. Dean's kinda screwed on the memory front. Because the strongest memories will come back first, and a lot of those are going to be traumatic. And without emotional context...it makes those little cracks so much easier for the demon to slide through.

Bobby and John aren't nice guys. Good men, yes. But not nice. But on one hand, Bobby's not wrong. Dean's dangerous, and if he's a loose cannon, things could go to shit real fast. And yeah. Sadly, John's probably one of the more moral of the hunters--scary thought there.

I think after two days of bitchy Dean, John's re-evaluating Dean's emotional state, and realizing that his boy will lie to him in a heartbeat. Which has to sting a little.

The demon isn't good at the shutting up thing, apparently. Evil damned paperweight.
