Ohhhh that doesn't look good. Peridot stiffens in alarm. Rita needs to release the magic in that gauntlet, but she's confident that the girl is clever enough to put that together for herself. While they're having their heart to heart, she scrabbles over to the limb Ignatius is trying to regenerate and tries to help by adding her own fire to it, breathing a steady stream. Which probably looks really stupid? But? Maybe if she can help him regenerate this limb, it'll stabilize him enough to buy them some time while they figure out how to work the power cells.
