What a sloppy ending!
I'm sure you guys remember the scene from season 5 when Dexter was with Lumen killing that one rapist, then Deb came in and cought them, but she couldn't see them because there was this half transparent plastic screen hanging through the room. This scene had so much incredible tension - I just loved it.
And now... here - Deb comes in ... DONE. All just within a minute. No tension, no musical support, nothing.
Sloppy, really sloppy - I'm so disappointed.
