Great ep. I especially loved the final scene where Dexter realized he killed the wrong guy and the look that Harry gave him. I guess that was bound to happen sooner or later, in his line of work!
The confrontation where he Blackmails Quinn into convincing that reporter to leave Deb alone made the ep for me also. Good stuff.
Wtf is up with Trinity's mood swings? It appears that he can't kill unless he's 1) on his kill cycle, - and/or - 2) The victim is part of the Trinity pattern he's been following all along. The sight of blood from the deer seemed to really gross him out. He's really complex. This may also lend to most of us' theory that he didn't shot Deb and Lundy.....
..looks like **** really hits the fan next week!
