Rainbow dash teaches scootaloo how to fly and they end up competing against each other in the equestria games where they are to fly against the best ponys in all of equestria. the prize for first place in 10,000 bits and a spot on the wonderbolts. Rainbow Dash will not let scootaloo get in her way so she badly injures scootaloo and wins the race. Years later scootaloo is thought to be dead and moves to phillydelphia and returns to ponyville to get her revenge on Rainbow Dash.
