Harry was unsurprised to find that Umbridge was sitting in on their Charms class, a clipboard and a quill in her hands. She seemed to be perched on her chair as if she thought it might bite her, and any time a student even looked like they might brush past her, she tucked her extremities in tight to her body and froze in place. Hermione was humming happily to herself as she pulled her charms book from her bag, and Ron seemed to have finally decided he was allowed to find this funny, even if he didn’t really understand it, and he too was suppressing a smile.
