WELP.
This thing may indeed have a rich inner life and a potent grudge against the surfacers who have mistreated it terribly, driving it to a mindless rage.
Unfortunately, it is currently attacking presumably-innocent bystanders.
And is making her think of Cryptids, which raises her hackles. So she has to take this seriously. (Is the minidragon still following her? She wouldn't want it to get hurt!)
These thoughts flit through her head as it's still emerging, and then she SCREAMS at it, with the sound reinforced with illusory power to the point of being damaging (at least to the thing itself), and surrounds its - head? main body? - with a cloud of darkness, and shoots down blue foxfires to surround it as fast as she can flick her tail, all while jumping down towards it.
