As kids, Twilight and Sunset were best friends, but a tragic accident cut their friendship short. Years later, Twilight investigates the incidents at Canterlot High and comes face to face with what appears to be a literal ghost from her past.
Things don't always work out the way we plan. Plans tend to fall through when it comes to certain things. Somethings--Ugh! Love! I'm talking about love! Help me! I'm Sunset Shimmer and I'm in love with-
Moons after their fallout and guilt, Princess Celestia jumps through the portal and finds Sunset Shimmer! Or does she? The girl she finds certainly looks like Sunset, but the girl claims to be just a simple musician who doesn't know Celestia at all.
When Sunset Shimmer hopped a freight train to Canterlot, a place she left as a child, she didn't expect people to know her name, much less blame her for something she didn't do. Meeting herself didn't make things any less confusing.
What's the use? No one wants to accept her as a new person. She tried the best she could to show the others that she's changed, but nothing's working. She can't blame them: who would believe her anyway? That is, anyone other than herself?
It's one thing to journey to the magical realm of your dreams. It is quite another to wake up there, in a new body. It is a third to realize you may not be able to stay.
After seeing a girl that looks like Sunset Shimmer at a carnival in town, Twilight spends a day with Sunset looking for her. Maybe seeing this girl will reveal a little more about what's eating Sunset.
Twilight’s newest friend is from the human world, is prone to nightmares, and has no idea who the other princesses are yet. Nothing can go wrong with this.
Sunset and her human self are in love. They kiss and cuddle and watch movies together and that's all cool and good and normal. She just has to tell her friends about it.
Sunset Shimmer meets Sunset Shimmer. Sunset Shimmer is very confused, but Sunset Shimmer seems to have the situation under control. Sunset Shimmer is also kind of attracted to Sunset Shimmer. Sunset Shimmer thinks she’s pretty okay with that.
