Sunset invites Fluttershy over to study for their test tomorrow. All is fine until Sunset asks Fluttershy a question about crushes, and some dormant feelings are awakened in Fluttershy's heart.
Sunset hated the holidays. So when Heath's Warming Eve came around she decided it was better to just drink the night away. But then Fluttershy showed up, and suddenly the holidays didn't seem so bad.
After the Fall Formal things don't go so well with Sunset Shimmer she slowly spirals downward before hitting rock bottom, moments away from doing something she will regret when, to her, the least likely of people come to her rescue.
After experimenting on her schoolmates' magical music abilities, Sunset Shimmer is haunted by glowy pink butterflies. Surely there's a reasonable explanation for this. Surely.
Everyone has secrets, yet some secrets can hurt others while trying to protect them. Other secrets can also offer salvation, though can be dangerous as well.
Sunset is feeling very lonely this holiday season, so now it's up to Fluttershy and her friends (EQG-verse) to help set things right for the former unicorn.
