This story is a sequel to The Core of the Problem

So, Twilight and Applejack are dating. She can't say she saw that one coming. She's totally happy for them... it's just kinda weird being around them, now. They won't stop just flirting and stuff.

But now there's a dance. The Cutie Mark Crusaders are planning the event of the season, and Rainbow Dash has to go. Why? Because Scootaloo. And she can't go alone; that'd be totally uncool: going solo right after two of your friends hit it off.

So she needs a date. That's fine. Easy, even--after all, she's Rainbow Dash. Who wouldn't want to go on a date with a legend?
