Well, I don't really have a direction in mind for the scene. Could go any number of ways, from stalling out into a stalemate to Clarissa actually managing to get Riv. I don't particularly mind him dying. What is for sure is that she's well and truly kicked the ant hive. Between attacking Riv and doing what she did to his bodyguards, I'm not seeing her as a welcome guest at Excelsior ever again.

In any case, Day will be fine. I shudder to think of Riv getting his hands on Tarasque blood, but I'm pretty sure Day has some in him, to give you an idea of the kid's healing factor. Unless a god-level being takes serious interest in seeing him stay down or some adventurers go questing for some doodad or other to keep him dead, he won't.
