Like with Jack, Peridot's going to be extremely vocal and offended about the suggestion that they give Banner up. Like, to the point where even after the issue is dropped, she'll still probably be a stubborn little shit about it and keep holding grudges as far as she can get away with, without destabilizing the team.

She's spiteful. And I'm sorry :'T

That said, she very much agrees with protecting the power/life support systems, because the engines blowing up is what happened on the last ship she was on, and she'd really rather not repeat that experience.
