Sonic the Hedgehog was the fastest runner in Equestria; not even Shadow could hold a candle to Sonic's speed. Similarly, nopony in Ponyville can match Rainbow Dash's aerial superiority and grace. When they both found out about each other, they became -quick- friends. Even quicker, they became inseparable lovers. Together, they ruled sky and ground and loved every moment they had in the spotlight, but they wanted some more, something special. And then it hit them: something only they could do that all of Ponyville would remember for the rest of their lives.
