Practical part...

She should've known she wouldn't have been able to escape playing this muggle game.

Maybe she could be that empire person. They seemed to hold all the power in the game when calling the shots. Besides, those were the people that didn't run, hit, or do anything in the game but just talk. Yes! It was perfect! Aw wait no, Patroclus wanted to be that person. Meh, she wasn't a beater either, so she'd just...stay back here then.

Waaaay back here. Maybe she wouldn't even have to play the game then.
