I honestly have NO idea what I'm doing with this one. It popped into my head demanding to be written so here's... this.

Twilight is a lot naughtier than her friends and family know. Not even Spike knows she's like this. After discovering a portal spell that can connect two distant points, any sane pony would use it to rapidly send letters and notes. Twilight decides she's just... gonna do something. Something crazy that may or may not get her and anyone else involved in a lot of trouble.
