- Harry Morgan: I'm not liking the trend here. You ripped a man apart in a public bathroom.
- Dexter Morgan: No one saw.
- Harry Morgan: You nearly botched Boyd's kill.
- Dexter Morgan: He's dead, isn't he?
- Harry Morgan: Yeah. And now you've got her. What's the first rule of the code?
- Dexter Morgan: "Never kill an innocent."
- Harry Morgan: "Don't get caught."

- Debra Morgan: I'm not looking for good right now...
- [last lines]
- Dexter Morgan: I read your letter. I know you have a family who loves you. You should go home to them.
- Lumen Ann Pierce: It's not that simple.
- Dexter Morgan: It is. It really is.
- Lumen Ann Pierce: Boyd wasn't the only one who did this to me. There were others.
- [angrily]
- Lumen Ann Pierce: It's not over.
