This story is a sequel to Vanilla Twilight

Rainbow Dash has a problem.

She might be in love with Twilight Sparkle and has yet to admit it to anypony, least of all Twilight herself. After the events of Vanilla Twilight, the two have grown much closer together, spending more time together and sharing their interests. Unfortunately for Dash, Twilight hasn't caught on to her feelings yet, and she could be content with just letting things progress as they are...

If only she hadn't sent that blasted letter admitting it.

Now, thanks to a pair of meddling princesses, Rainbow Dash finds herself on a globe-trotting journey with the subject of her affections. On the surface, it might just seem like a simple task for the Princess, but for Rainbow Dash, it might be the very thing that forces her to come clean with her feelings, or forever face her doubts. For her, in the world of life and love, sometimes it's best to take it one dream and disaster at a time.

We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.

Clarifications:
Many have wondered what Twilight looks like and such so to clarify, she does not look like a human female, she retains her fur coat, she is of human height and has hands. The facial structure is more detailed such as where the eyebrows should be there is a darker patch of coat much in the color of her mane.

The story starts a few episodes in, around halfway through season one I would say, some shall stay canon whilst some with alter, I am sorry for this inconvenience.

Twilight is still Twilight in every way, though she has been with little to no contact throughout her life apart from when the Everfree retained people, in such her words would become haggard sometimes so that's why you will probably go "huh" when you first see her talk to the CMC.

That is all for now.

A young man who has recently lost his parents finds himself in a situation where he's caring for a young woman who seemingly has just appeared out of mid air. She knows nothing of human customs but speaks English very well and she's apparently well educated although in what could only be called esoteric knowledge.

She also claims to be a pony. But nobody ever said that relationships were easy.

Twilight didn't know what came over her. At one point, she was having a wonderful tea party with her friends, and the next thing she knew, she was trying to kill the princesses.
This could have something to do with the fact that nopony would listen to her at her brother's wedding, everypony thinking she is crazy, or even the fact that Discord was set free without anypony noticing.
She finds herself at Celestia's court, facing crimes she didn't commit.
"Twilight Sparkle, for stealing the Elements of Harmony, attempting to kill me and Princess Luna, and Betraying everything you were supposed to protect, you are hereby banished from Equestria, never to return!"
Celestia's words continued to ring in her ears as she followed the road out of Equestria. She would never see her friends again.
