[the two brothers are in an airshaft and getting a bit uncomfortable]
Murphy: Where the fuck are you going?
Connor: Shhh. I'm figuring some shit out here.
Murphy: Ahh, fuck you! I'm sweatin' my ass off draggin' your fuckin' rope around. Must weigh thirty pounds.
Connor: Shhh. We are doing some serious shit here, now get a fucking hold of yourself!
Murphy: Oh, *fuck you*! I'm not the rope-totin' Charlie Bronson wannabe that's getting us fucking lost!
Connor: Would you fucking shut it?
[taps him on the head with his flash light, and both brothers start fighting in the air vent until it gives way]
Connor: You mother- Jesus fucking Christ!
Murphy: Oh, shit!
[the vents give way]
