Sarah was NOT going! She was not! Not, not, not. There was nothing anyone could say or do to make her, and just to be sure, all of her piercings were non-ferrous so there! She wasn't wearing a costume, she wasn't leaving her room, she had work to do. There were at least two new students to get set up with everything, one of which needed all sorts of different issues.
She wasn't in costume, she was barely dressed, still in her PJs pretty much. Not going!
