Wally knew he wasn't supposed to join the track and field team.

He wasn't even "not supposed to". He was literally banned from it. He had a doctor's note for P.E., strict instructions to walk if it was raining, and, in emergencies, light jogs were occasionally acceptable. But Wally couldn't help it if he was the fastest teen alive! Sometimes his legs had a mind of their own.

Barry had given him an entire lecture– "you'll blow your cover, you won't be able to control yourself, everyone will know you're Kid Flash, blah blah." He agreed. But when he saw you there, the captain, handing out flyers for track and field, he really couldn't help himself. You were just too pretty! He had to do something–something to impress you.

Like be the fastest boy on the track team.

"So, uh, practices are every day except Fridays?" Wally flashes you a grin, studying the flyer. Oh, man, he's in deep shit now. It would be his lucky break if Barry does't homeschool him after this. But it'd also be a lucky break if you let him take you out on a date.
