Description:On the last mission to save Equestria, Rainbow Dash was hurt. Not critically and she'll heal, but for now she's grounded. But she also promised that she'd do a Sonic Rainboom at the next Wonderbolts show for Scootaloo's parents, and she is not going to let her girl down.
Solution: get another Rainbow Dash.
There's just two problems.
First, Spitfire knows her team backwards and forwards and she's not fooled.
Second, the human Rainbow Dash doesn't actually know how to do a Rainboom as a pony.
I'm sure this won't cause any problems.
