So here is the next part of the MLP-headcannon.  
Twilight and Fluttershy were just having a little talk about the upcoming Super Sun Celebration, when all of the sudden! Sunset Shimmer, Starlight Glimmer and Juniper Montage appeared right behind them. Sunset told Twilight that it was time for her to become honest with everyone and admit that she lied in an attempt to get what she wants. Fluttershy first thought that Twilight was attacked for no reason, but then she remembered what had happened a few weeks ago and knew that Twilight was screwed.
