Turns out, I don't need to do either of these things, but also, I don't think Pullo (for some reason I keep calling him "Pillow") would like waking up and finding out his girlfriend got pummeled for the waitress dying because of forces that were, technically, out of her control.
Say what you will, but Missile is fond of the Boar primarily because of his lack of similarity to humans in general, the atmosphere of the Inn, and the food and drink. Seeing a normally pretty sane individual lose their shit would surprise even her; she's pretty fucking nuts, but when it comes to nonhumans like animals, other species, etc., she cares somewhat.
Also, wrecking the shapeshifter's insides has sated her bloodlust for the day, so there's that too, and Pullo's getting an interesting late-Valentine's gift as a result!
