Slice of Life
[First-Person told from Scootaloo's prospective]
Scootaloo is torn apart by a genetic disorder, or at least, it might as well be. See, she now recently discovered that she likes her close friend, Sweetie Belle, which is on so many but mostly two important levels of completely and utterly wrong.
Firstly, they are both fillies. You ever heard of two colts or mares marrying each other? Were anypony's parents both fathers? Precisely. Yet Scootaloo couldn't dodge away those feelings for Sweetie Belle. All she can feel is awkwardness and stutterers around her now, almost as though anything she said could mess something up.
Secondly, that colt that just moved in, Button Mash, she clearly like-likes him... maybe. He's also a blank. They've been hanging out after school, drinking milkshakes at Sugercube Corner. Sweetie Belle's recently gotten into that mining game again by that colt's influence, which is nothing but a halt on crusading. Does she even care about getting her cutie mark anymore? Sweetie Belle once didn't go crusading so she could go to his place and and play that game with him... but it was raining heavily as well, so that was probably a reasonable move. Did they, did the two actually have a sleepover once? His mom allows colt-filly sleepovers?
Button Mash is pretty much stealing her extremely slim chance of getting Sweetie Belle as a marefriend (which sounds nearly as weird as giving up crusading!). Does Sweetie even like him?
If she does, Scootaloo's going to make sure she won't.
