Excuse me while I scoop my jaw up off the floor.
That final scene. Wow. With Deb walking in on Dexter, gun drawn, in the midst of another murder. Shades of the premiere. And Dexter echoing Hannah's acceptance of death. In that moment, Dexter, for the first time, acted in a totally selfless manner; willing to die to save the "goodness" in Deb. But when the shot rang out, he was spared, and LaGuerta was done.
