Okay, well, that's a gun aimed at him now. Which, fine, he's used to that. John lifts his hands so they're visible, and shoots Gwen an entirely fake fuck-you smile. Sizing her up, though, she's nervous. Distracted. He could probably disarm her if he needed to. The question is how likely they are to shoot Ianto.

"Listen," he says, "it's nothing personal, but I really hate having guns point at me. Now, I know I'm interrupting some good drama here but -- which is a pain, I'm sorry -- but maybe we could all just take a minute to lower our weapons? Then everyone would feel better about talking this over."

Right? Right. Probably. If not, the question is how does he force it. Escalate by holding the gun on Gwen (apparently) instead? Who can hold a bluff longer?
