The stunning season finale of Dexter! I know this is a fansite, but I’ve found this season pretty weak. I didn’t like finding out that big surprise about the real killer (I won’t name names, for those of you not caught up). What did others think? Anyway, here is Dexter episode 12: where the righteous and the wicked meet. This is it! The last episode of season six. It promises to be an incredible episode! Almost every character on the show faces mortal danger in this episode – and some won’t live.
