Pearl will be all over this, seeing as some of her close CR has signed up to being jailed. But in general, she'd be gung-ho about saving everyone from execution. She'll rush in with swords drawn.

Before all that though, Pearl will be an absolute mess, worrying about those of whom were captured. Plus she was one of the invited few to the Chimera gathering. So she may need some emotional support. Other than that, I'm up for any kind of interactions!!! And she will totally join in with any secret meetings that will arise.
