Chrysalis, after trying to bring immense pain to Celestia, her sister, and the mane six, found herself under the furious and soul crushing gaze of The Psychopath. No one touches Tia-Tia and Woona while he remains. Having no sense of time, Psycho thought and saw Celestia and Luna as the little fillies he once looked over as a foal-sitter.

To teach the changeling queen that attacking defenceless fillies is wrong, he decided to turn her into one herself and smack her far away with a baseball bat. Instead of staying as a filly, he decides that it would be better to just return her to her own infancy instead of that of a pony.

Now he's watching her, making sure she learns her lessons right, indirectly taking care of problems that might prove a bit much for a little changeling.

This a mini-story after "The true Psychopath" and before the eventual sequel.
