Alright I can't remember what fanfic this was used on, but if you ever see it don't read it. It is so trite and repetitive you end up reading the same chapter, for every chapter.

The short version is Cadence was actually dead and there were 2 different Chrysalis, so she reveals to shinning that she's not Cadence, he's shocked, but gets over it in 5 minutes. So the rest of the story revolves around Chrysalis being discovered by every single character and being a complete cycle, riveting
