If Korrin was in full health, then no, there wouldn't be much that could prevent her from leaving as she pleases. As it is, her strength is severely sapped, and the lightheaded spell that brought her back is enough to prevent her from departing again...at least for the time being. She's as stubborn as she is ill, so it's probably just a matter of time.

Korrin's eyes take a bit to focus, distracted as she is since this all began. "I'm...trying. Fucking spirits won't shut up, at least when I'm not trying to pay attention to them. Then when I do, they go mute. Fucking annoying...." She sways, nearly collapsing but a quick step forward from one of the scouts has her supported before she can accidentally crush Eirlys.
