Base off Rainbott’s muffins creepypasta rewrite.
You know how when twilight keep going to the past to stop starlight glimmer? I keep imagining that thing would happen to Applebloom when she gets the time scroll and becomes an alicorn, and in the new timeline she still an alicorn because a alicorn made her one!
While I do like the way AB got pinkie arrest; I feel like if pinkie pie knew about the alternate timeline; i feel like she would try harder to hide or torment Applebloom; especially if pinkie pie also stay as a alicorn in the new timeline too. So basically it would be 2 alicorn who are brand new at magic and flight; would have a messy battle that involves using the time scroll over and over. I think eventually Applebloom somehow rewinds time to a point where pinkie is out of town or somewhere, or Applebloom immediately goes to princess Celestia for help. And with the power of 3 (or 4 if Candace is there) they would defeat pinkie!
That also means that in this world alicorn can be killed probably only via beheading and Applebloom is still a princess. But probably of one of redemption or forgiveness or something..
