"HECK Y--" Bart started to say, more loudly than he'd intended and glanced suspiciously towards their teacher who gave him a lazy sort of side eye. The kind of side eye a teacher gave when they wanted you to know that they knew you were doing something wrong and to see if you'd correct it before they had to take action because really they didn't want to deal with you right now. Bart got the message and quickly adjusted his volume back to a whisper.
"Heck yeah. I'm pretty good at calculating velocity and speed and stuff..." He said with a shrug, trying not to reveal too much. That wasn't revealing too much, was it? "What're you good at?" With any luck, they'd compliment each other's strengths and weaknesses. Bart could be good at the speed part and Jaime could be good at the focus/patience part. With a combo like that, they couldn't lose!
