Dexter Morgan:
Speltzer is going to kill again. An alarm is going off inside my lizard brain.

Debra Morgan:
Great, now my brother has a lizard brain.

Dexter Morgan:
The amygdala. The most primitive part of the brain that senses danger. Harry taught me to listen to mine.

Debra Morgan:
Oh, well, you'll excuse me if I don't put my faith in your amygdala.

Dexter Morgan:
But you already have, Deb, dozens of times. All the murderers I've helped you catch, who got brought down because of my hunches. My lizard brain has been your secret weapon all along. You just didn't know it.
