Oh my goodness. Think back to Beyond Forever, when Purple and Hoity came to the doughnut shop. This puts Rainbow Dash's "stand off to the side, waiting for them to clear the door" in a completely different light. She's not just impatient, she's trying to mask her disgust at seeing Hoity.
So where do the Wonderbolts fit in all this? Is it because Dash honestly took to flying/athletics, and sees it as the best prize any young flyer could ask for? Or does she see the physical demands of the job, combined with the fame it would bring, as the ultimate "screw you dad"?
