Short story that happens at the EXACT same time as "Return to the Mirrorverse". While the Mane Six and Spike are busy helping Captain Goodguy and Chrysalis against the super-charged Erroneus Equines, the Mirrorverse versions of Trixie, the Flim Flams and Derpy are busy helping their recently reformed versions of Celestia and Luna re-learn on how to deal with situations in a completely just manner and save violence as an absolute last resort.
