Botros was the first one to stand in line? Oh! He had a big grin on his face, and he was standing straight, he waved at the kids who seemed... huh, some of them were excited but the others were timid. This wasn't a punishment, Merlin, this was a game, everyone should be having fun and smiling! Like he was. He waved at the Potions master then.

Okay, standing up straight over here, he waited for the rest of the 'chosen' staffers to join him.
