My thoughts on EG Spitfire is that she's actually the captain of the soccer team (come on, really? Rainbow Dash is the captain of every team? Let's be realistic here.). Rainbow Dash wants to be on the soccer team but there are no open slots. Spitfire is the popular jock type who's still down to Earth, and Rainbow Dash spends all of her time trying to look cool in front of Spitfire so she'll be her friend.
