Phasma
Much of my behaviour here is because I rankle at losing control over myself and over the situations I'm in, yes. It's why I disagreed to that ridiculous constitution. If I have to be here, under the control of the scientists, I'm not going to let fellow captives have any control over what I do.
You say there's dissonance. I don't particularly feel it stemming from myself. If you disapprove of my behaviour, of how loud I am, well, there's nothing I can do about that. My personality won't change just because it irritates you; this is the way I've always been.
I have been attempting to tamp down on some of my baser instincts, though, for the sake of comfort and eventually getting my full powers back. Instead of threatening to attempt to excise me from existence, you are free to help with those goals.
