Okay, so there was no way Sophie was going to write a two-foot-long parchment about Heimdall--whoever that was. Cleaning the armor, although really something she thought the house elves should do, seemed so much easier and faster. So with her wand in hand, Sophie made her way to the third floor and joined the group of students already slaving away.

Did she know what she was doing? Er, ...no. But there were loads of older students here, so the plan was to latch onto one of them and just follow the leader. So having said that, Sophie scanned the crowd, looking for someone who probably knew what they were doing but wasn't already working with someone.
