Neither Rarity nor Fluttershy spoke in this episode (however the former says "Ugh!" when Rainbow Dash says "Hello?! The Wonderbolts have bleachers, too! We practically invented sitting on bleachers!")
Short Fuse, a member of the Washouts, was previously seen in the episode Top Bolt, as a contender for the Wonderbolt Academy (apparently, it didn't work out).
Friendship Report: Rainbow learned to let Scootaloo make her own decisions.
