Well, Mimmi isn't asleep, but she's not actively moving around much, either. She managed to stumble into the botanical garden, and it's possibly the nicest thing she could find on this dingy barge. She's propped herself up against a tree, picking the petals off a poor, unsuspecting flower.

After all she's been through, it probably isn't safe to not be fully aware of her surroundings, but right now she can't bring herself to care about much else.
