Brother Sam: (to Dexter) You don't fight like a lab geek.
Dexter: Omar did not have this coming. His demons were gone. Men can change. Men maybe... but what about a monster?
Dexter: As much as I want Harrison to stay this way forever, from now on, the only wolves in his life have to be the stuff of fairy tales.
Dexter: (voice over) Rituals are important. Not just for a serial killer.
