The way of doing it has to be specific and cinematic as well as consitent -- so maybe we'll watch the race with this in mind and come up with the way to do it.
As for the bullying -- I see what you mean InfoDroid. I like the take that is mostly there in TPM which is that Anakin lets all that roll off his back. But in the heat of the race, with the right motive and opportunity (in terms of footage we can use) I think a "Force Moment" would be perfect for cementing Qui GOnn's opinion of hte boy.
