Cole glanced at John, wordlessly wondering the exact same thing he was - why were Peter and Iris looking at them? This had been entirely unexpected, and obviously no one wanted to shoot anyone, but he didn't know what he was supposed to say. She was never going to shoot straight if she kept freaking out, but he couldn't bring himself to tell her to stop. He didn't think someone had set this up, but rather something.
"John's right." His voice was just as quiet, but he wasn't going to stand there and tell Peter that no, they didn't have to do this; they could all just stand around and wait instead. "That plaque is there for a reason - doing what it says is the only way to get out. I'm sorry. I don't want to be shot at any more than you want to be the one who shoots, Iris, but it'll be okay. It'll be fine."
