For the first time since coming to this world, Sunset was to have a happy holiday spending time with her friends. That isn't to be though as a new blog by an, "Anon-A-Miss" turns the whole school against Sunset, including her friends. After the truth is revealed though, Sunset isn't really offered any apologies by anyone other than the real person, or people behind the blog; Applebloom, Scootaloo, and Sweetie Belle. Leaving Sugarcube Corner while everyone is talking about what had happened. As memories of the past week plauges her mind, Sunset decides to just give up since all of her hard work trying to prove that she had changed was for nothing if everyone could so easily be turned against her. Will the girls save her and prove that they love her, or will it be too late?

Anon-A-Miss. They happened, people were hurt, the mess was cleaned up, people are begrudgingly forgiving the trio responsible, if only for Sunset, and everyone in the school is starting to become friends again. The problem was solved, right?

Not if you ask Rainbow Dash. She's still pretty mad at herself about it, after getting all the details shown to her. So are her friends, just slightly less so than her.

Yes, this is another Anon-A-Miss story, but at least it doesn't happen during the fiasco like nearly every other one I've read. I was considering a way I could write a story about the entire thing that wasn't done to death. Then I realized there weren't many stories that followed this particular line of thought, so I went with it to see what would happen when it was filtered through my brain.

Edit: HOW DO I KEEP HITTING THE FEATURE BOX!? HOW!?
Edit 2: Now has a Bookshelf to keep track of all the stories related to this one. TADAAAA!

Sunset Shimmer is devastated since her friends abandoned her because of Anon-A-Miss. While she tries to figure out what to do a new girl arrives in town, not knowing that she will be involved into an event she doesn't know about or has control over.

In the EQG Holiday Special, Sunset figured out that Anon-a-Miss was actually Scootaloo, Sweetie Belle and Applebloom.
But what if things happened differently?
What if Sunset never figured out who Anon-a-Miss really was?
What if her friends refused to listen after her little chat with Twilight?
