Arthur: What about his security? It's gonna get worse as we go deeper.
Cobb: I think we run with Mr. Charles.
Arthur: No.
Eames: Who's Mr. Charles?
Arthur: Bad idea.
Cobb: The second we get in that hotel with Fischer, his security is gonna be all over us. We run with Mr. Charles like we did on the Stein job.
Eames: So you've done it before?
Arthur: Yeah, and it didn't work. The subject realized he was dreaming and his subconscious tore us to pieces.
Eames: Excellent. But you learned a lot, right?
