He doesn't expect her to escalate? She's always so calm, and she wants them on her side, right? When his hand goes through her, he's not surprised and he sighs, beginning to straighten. He's furious, but he also knows he can't do anything to her, and that initial spike of anger is passing through him.

Instead of letting him settle though, she's suddenly advancing on him. He moves to get his hands up between them protectively, but it's like something is holding his wrists down. He's trapped. He can't move his body, and while fear grips his chest for a moment, his brain also uh lights itself on fire. His anger returns doubled and then tripled again as she bombards him with questions instead of answering a single one of them. By the time she's finished, he snarls at her, barking, "Let-- go--!"

And he lifts his foot. To slam it into her chest.
