Am I the only one who noticed that they actually have a hell in this universe?
Granted, it's Greek hell (considering Tartarus is more or less unofficially the "hell" of Hades), but still.
Well, it didn't sound like an "underworld" so much as like a prison for the creatures too dangerous to leave free. And considering dragons and ursa majors are allowed to live in Equestria, just imagine the kind of power anything deemed dangerous enough to be locked in Tartarus is...
The fandom theory that G4 Equestria is the pacified G1 Dream Valley makes more and more sense..
Saw the episode now, was awesome (Twilight using high-end magic, Flowerpot, Terminator expanding timetravel bubble)
The creator of Friendship is Witchcraft probably felt really weird during this ep.
