Joe was sitting at his window, thinking about the staff meeting when someone knocked on his door. He'd assumed the reason he'd felt compelled to some to Hogwarts would make itself known in due time, he just also assumed that it would make sense. This kind of thing, disease, isn't exactly his forte. So lost in thought, he jumped at the intrusion of sound, then took a quick moment to calm himself down before standing and opening the door.
He wasn't surprised to find William standing there, looking almost as exhausted as Spencer. "Hey, don't worry about it," Joe said with an easy, tired smile. "Things come up, it's not a big deal. Come on in."
