Bored due to there being nothing for her to do, as no Friendship Problems have arisen that have needed her help, Twilight decides to visit her Canterlot High friends and see what's going on.
However, something goes wrong and the portal closes, leaving Twilight stuck on the other side. That's fine though. She can just hang out with her friends and wait it out.
However, it won't be that simple. Though she turned into a human like normal when she arrived, Twilight is now about 6 to 7-years-old and it seems she has access to her magic as if she were still an Alicorn. The human world isn't prepared for this.
AU universe where Friendship Games happened before the Season 5 finale, so Twilight's human self is already transferred into CHS, but pony Twilight has yet to go with Fluttershy on their Friendship Mission.
Rated Everyone for now, but may change it to teen depending on future chapters
Note: Twilight didn't see Sunset's messages in this AU due to them coming whilst she and the girls being away dealing with Starlight, followed by how much she'd been avoiding her castle in the following episode.
Spike is the reason the messages never got answered though, due to Big Mac accidentally knocking the book of it's place on the machine whilst he and Spike were in the library, Spike not being there in time to see it glowing to indicate messages being received, so he just placed it back on there without a thought.
