Considering the witch was experimenting in ways to best destroy Erasers? I wouldn't doubt it. [Baba Yaga was being surprisingly helpful, and was continuing to be so likely because she was more pissed off about the Story Eater than them goin inside of her hut.

Better to keep her on their side if any stories about her were true, too.] I can believe, and suspect, that we are being watched one way or another. Already know Story Eater is willing to pretend to be a hero to catch us unaware- did that at least once already back in the story realm.

Not sure it's still in hiding after taking the moon, but reason I got that Eraser in a jar tucked away where it can't really do any sort of looking, too.
