On the other hand, does Goran accidentally hit her with his attack? And he can't avoid attacking, otherwise Reinheld won't get out of that room in a reasonable time. And even if he doesn't hit her, what about the archers? They'll burn her again...
If Tiril's Flash spell is ready, I'm ready to send her to her death and kill at least those mages with the Flash spell who don't have a mirror (I thought there were some, but it's better to double-check).
