Well that just happened.
At least, buoyed by a wave of confusion and guilt and anger, she is no longer crying.
She wipes her eyes and drinks one more cup of water and looks around the room for... she's not sure. Someone who doesn't seem nice in the weird insidious way where they'll try to stop her, and doesn't seem fragile in the way where they'll have a breakdown if she explains herself, and doesn't seem evil in the way where the school as a whole will be worse off if they take her stuff? That is a lot to ask of her historically dubious ability to read people's intentions, but it's not like she can ask anyone else for advice.
