Dexter certainly had himself a good day (or couple of days). He managed to get Louis fired, dumped by his girlfriend, and (indirectly) killed. Then, right after he told Deb that what he does helps people by getting killers off the street, the killer Dexter was stalking (and Deb warned Dexter off of) kills a girl and gets away, right under Deb's nose. Oh, and Dexter saves Deb's life from the killer. So she lets him move back to his own apartment. I did not like the killer's escape. I would have expected Deb to handcuff him (even if he was unconscious), and then I would have expected her to run after him when they realized he was out of the house. And Deb immediately calling a car to watch the cemetery would have been the obvious thing to do. What is the deal with Sarah, ummm, I mean Hannah? First she tells Dexter she prefers Mr. Morgan, then asks him to call her Hannah. Is Dexter's drop of blood on the plant significant in some way?
