Dexter: (voice over) Maybe I'll never be the human Harry wanted me to be, but I couldn't kill Tony Tucci. That's not me either. My new friend thought I wouldn't be able to resist the kill he left for me, but I did. I'm not the monster he wants me to be, so I'm neither man nor beast. I'm something new entirely, with my own set of rules. I'm Dexter. Boo.
