[Isaac watches her, pushing back against the wall with a sigh, not quite meeting her eyes anymore. He doesn't know how to reply to that, not really.]

Yeah?

[Quiet, but not quite soft, like he's still tempted to react with anger. His gaze flicks back to Steph then, charged, still just as dangerous as the boy who was sparring with her a moment ago.]

This is about Jesse, isn't it? Look- that little shit needed a good talking to. I'm not afraid to admit that. [A pause, and then-] -and I'm not afraid to hurt people. In case you haven't noticed, it's one of the only things I'm good at. I know there's a line, and I know I'm not going to cross it. I won't.

[And then again, like he's saying it more for himself than for her.]

I'm never going to lose control like that.
