Cutter: I saw you, drop the knot again...?
Julia McCullough: I think I turned my wrist...
Cutter: Some nights you just don't get it, do you? I mean, if that knot slips and Julia's on the hoist, she'll break her leg!
Alfred Borden: It's a wrong knot.
[pause, Cutter stares at him]
Alfred Borden: Like I said, the Langfeld Double will hold tighter!
Cutter: The Langfeld Double isn't a wet knot! It's too dangerous - if the rope swells up, she won't be able to slip it!
Julia McCullough: I can slip a Langfeld underwater.
Alfred Borden: [looks at Julia] She can slip it, we can practice...
Robert Angier: Hey, Borden, he said no!
Alfred Borden: [scoffs] Oh well, you know knots better than me, do you?
Cutter: Listen! No more mistakes!
