Well that escalated quickly.
Given the fact that this episode was called "Do the Wrong Thing," I suppose it's a little wrong to come down too hard on Dexter for returning to his old ways of bad decision making, but that doesn't mean that it's not frustrating to watch. All in all though, I'm enjoying Dexter's time with Hannah, even though it steps on the toes of more than a few things.
