Looking for a fanfic recommendation with a certain topic

Hey, does anyone know of any fanfics that take place in the events of A Canterlot Wedding pt.1, where after the end scene from that episode, it turns out that it was actually the real Cadence that she was accusing of being evil? It would be interesting to see what the end results it would have. If there do exist any fanfics about that, post them here.

^{Well there's True Love Never Changes where it turns out that Cadence has been Chrysalis all along. It's a romance fic that's decent but not amazing. Worth mentioning.}

That's cool, but that's more like the actual show. I'm looking for fics that use Cadence actually being Cadence. It could tell about how Twilight's relationship with her brother, friends, and mentor have been turned upside down because of that situation.
