I am psychic AMA · 2:06pm May 28th, 2017
So, I recently started a story called The Worst of All Possible Worlds. It's a story where Sunset Shimmer returns to Equestria to get a new journal and accidentally ends up in the crossfire between Twilight Sparkle and Starlight Glimmer during the Season 5 finale.
Well, just as it so happens to be, there's a few Equestria Girls Specials coming out later this year. The third episode has exactly the same premise without the Season 5 finale part.
Here's the description from IMDB:
As the pages in her journal run out, there's only one thing for Sunset Shimmer to do: return to Equestria to get a new journal! There, she meets Starlight Glimmer and agrees to bring her back to experience life at Canterlot High. But while Sunset Shimmer was away, a revenge seeking Juniper Montage finds a beautiful hand mirror enchanted with Equestrian magic. Not only can it provide a window into another land, but if you push the right button, it can also make things disappear into limbo, trapped between the two realms!
And here's my description:
Sunset Shimmer has run out of space in the journal she uses for friendship reports. On a whim, she decides to return to her homeland for a brief visit and to get a replacement journal. Unfortunately for Sunset, a pony named Starlight Glimmer was busy enacting her revenge, catching Sunset in the crossfire and placing her in a different timeline than she expected. With no Elements of Harmony, no Princess Twilight Sparkle, and no clue, Sunset must reunite the main six, save the timeline, and find a way home... eventually.
Am I psychic? Yes. Yes I am. Ask me anything relating to pony and I will answer.
