- Mike Scarlatti: [on radio] There's an extensive air vent system, one in every room.
- Sam Braddock: [outside autopsy] You wouldn't know it from the smell.
- Kevin 'Wordy' Wordsworth: Breathe through your mouth.
- Gregory Parker: I know it's hard to lose a child.
- Frank McCormick: It's even harder having everybody thinking that you killed her.
- Gregory Parker: [with Sam trapped in the now activated ventilation system] Spike, can you try to override the ventilation system?
- Mike Scarlatti: There is do or do not, there is no try.
- Ed Lane: [arrives at wife's hospital room, son stands up and begins to cry] Are you okay? You okay? How you doing?
- Clark Lane: There was so much blood. I was scared.
- Ed Lane: [hugs him] You did good. You were the man of the house today. I'm so proud of you.
- Jules Callaghan: What would you rather live with, believing you're innocent or know you're guilty?
- Kevin 'Wordy' Wordsworth: Nah, you don't forget you killed your kid.
- Jules Callaghan: Oh, I think he did. I think that he blocked it out.
- Sam Braddock: He was as good as convicted; he had a ticket to freedom, but instead of running, he turned around and went home.
- Mike Scarlatti: 'Cause it wouldn't have been freedom leaving behind a wife who thinks you're a killer.
- Gregory Parker: So, Frank was innocent all along.
- Sam Braddock: Tell me we haven't had days when we want to cut to the chase.
