The monsters don't seem to realize she is there, but Mulberry wonders if talking to them might lead to a way out. She isn't sure what else to do, maybe other than digging a tunnel out. Maybe if she can get to the roof somehow? The mare is a little worried what might happen to the spell on the apartment if she starts putting holes into things.
Mulberry supposes she could wait a bit, maybe practice some of the spells she knows.
