They did not run toward the MC. They just stood there speechless and couldn't believe what they were seeing.
Okay, if that's how you feel about the jocks, I respect that. But it's out of our hands anyway because it's "canon".
The part in the shower bothers me a little, Tybalt is afraid of the MC either way. It doesn't matter if the MC punches Tybalt in the face with his fist or not. But it will probably be that Tybalt can be pissed because he got the tennis ball from Isabella before.
I don't want to belittle the people who fight with the athletes. Let everyone decide that for themselves, please. I for one decided against it because the 3 athletes did nothing to the MC.
