I have a little question for the Hive Mind... Not sure if anyone remember the episode "Do Princesses Dream of Magic Sheep?" And about how Luna created the Tantabus to torment her... as it was time ago in season 5

The question is... Should that make the Tantabus the little sister of Selena/Nightmare Moon or the little sister of Nightshade? While it's for a future, it could be good to know if it's left as a surprise or if the hive mind should decide it.

I believe it would be NIghtshade's aunt considering Luna is Selena's Sister/Other half/mother? (My god they have a weird family)
