Re: WHAT DID YOU DO?
Oh, she's going to end up being his BIGGEST cheerleader when she sees what he can do. (And someday they're going to have to end up being sparring partners just for fun, because he may be the one person she'd actually be tickled to lose to just because the teleporting is so COOL.)
WELL NOW SHE NEEDS TO GIVE HIM A NICKNAME SO THEY MAYBE LOSE. Honestly in the heat of competition she's going to be hard pressed to come up with anything witty, so he may just get dubbed Pointy for the duration. Because ears. It's not good, okay! It's absolutely what you do after a game. It'll either be a celebratory selfie or a pouty one, but either way her partner in trying to crush the competition will be saved from the post-game grumpiness she's going to inflict on everybody else!
