It is extremely tempting to jump the rat. Peridot feels like she could pull it off; just drop right down, turn back into a raccoon and get it into a headlock or something, like one of those action movie heroes.

She knows that would be foolhardy, though. She didn't exactly have time to see Syrlya escape so for all she knows, she's the only one who didn't get caught, and therefore might be the only one in a position to get them out of there. So instead of charging in, she carefully clings to the underside of one of the pyramids on her own empty cage. If she can, she'll wriggle into a position where she can watch the rat, but also be close at hand to Do An Assault if they look like they're going to try anything harmful to her companions.
