Tony: [on phone] I can't hear you, McGee. I'm in the basement.
McGee: Why?
Tony: Because I don't want to talk about the case in front of Leila and the kid.
Abby: Listen, Tony, this is really important. I need you to check the seams of the walls.
Tony: The walls?
Abby: Well do they appear to be removable?
Tony: Huh.
McGee: Abby.
Abby: Or a tunnel, maybe?! It could be hidden under something on the floor. Something that looks like it doesn't belong.
Tony: Actually, I think Colonel Hogan has got a radio in the coffee pot, but the tunnel might have been filled in.
