To be fair, she does have fire-related trauma so it's actually not that far-fetched that she wouldn't think very logically in this particular moment.
I'd get that but as is it feels like there's a huge problem with her attitude plus the blocking/pacing?
- When he starts the fire on page 33 we can see a pretty large section of the room that's not on fire at all.
- There are a lot of panels between that and the end of the chapter, which makes it feel like a decent amount of time has passed.
- She doesn't seem panicked or even like she's moving especially quickly.
Overall it feels like there were maybe five minutes before the fire got super bad where she did nothing
