I agree that this episode was a little underwhelming. I guess I had to be given it was a setup for the season.
I think we saw a little bit more of Dexter's ability to feel emotion. That's the first pure rage kill we've ever seen (bathroom), and his willingness to engage his emotions brought Harry back. He's finally able to feel love and remorse and simply not recognize what he should do to appear like to he does.
As for Deb and Quinn, I hope Quinn

ing dies. He's got two things going against him. 1) Everyone Deb

s either dies or almost dies. 2) Everyone who gets too close to Dexter dies. Deb pisses me off because it's obvious she uses sex as an emotional coping mechanism.
