Discord's having a tough time. He could really use the attention of his best friend. Unfortunately Fluttershy's out of town with her friend Tree Hugger.
Who else could Discord go to? Precisely, Twilight Sparkle.
But as soon as Discord finds out Twilight is on her way the 50th Rainbow Falls Traders Exchange anniversary with the other princesses, Discord, the lord of chaos, who isn't really a lord anymore, and definitely isn't allowed to spread chaos, feels like a lonely disaster.
