Nick Fury: Agent Romanoff, would you escort Dr. Banner back to his...
Bruce Banner: Back where? You rented my room.
Nick Fury: The cell was built...
Bruce Banner: In case you needed to kill me, but you can't! I know! I tried!... I got low. I didn't see an end, so I put a bullet in my mouth... and the other guy spit it out! So I moved on. I focused on helping other people. I was good, until you dragged me back into this freak show and put everyone here at risk!
[Banner slowly gets upset as he looks at Romanoff, who gets unnerved]
Bruce Banner: You wanna know my secret, Agent Romanoff? You wanna know how I stay calm?
[Black Widow and Nick Fury have their hands down to grab their guns]
Steve Rogers: Doctor Banner... put down the scepter.
[Banner looks down and is shocked to see he's holding Loki's scepter; the computer beeps]
Tony Stark: Got it.
[Banner puts down the scepter and heads to the computer]
Bruce Banner: Sorry, kids. You don't get to see my little party trick after all.
