Set JUST before Mina's Visit, with help from VISION-KING. Princess Luna gets the idea to set up a support group for reformed villains, so they can all help each other fight the temptation to return to their old ways. Will Trixie, Gilda, Discord, Diamond Tiara, Starlight Glimmer and King Sombra all be able to last through the first meeting without droving each other crazy?
You know, I was exp this to be a suicide squad kind of thing.
