Edie is thinking about magic, because what else do you do with your spare time when the good part of a book isn't calling you with its siren song?
Her thoughts are interrupted by a knocking on her door. She gets up to answer it.
She comes in a little later, with her twin beside her. Neither of the two is speaking, but their facial expressions suggest they might be having a telepathic conversation.
Edie notices when he waves, waves back, and when the two of them have collected food they head over to where he's sitting.
