Blue Moon

I bet Celestia will do it if it does happen.

I don't care either way, but I'm just interested int the antagonist of it. She reminds me of Sunset Shimmer. Also Sunset Shimer's toy box says that she found "a gate way to a far of magic adventure" so it may actually be referenced a little bit in the show later on.

She is Sunset Shimmer.. She will forget everything, I do not want this to actually play a part in the show itself and it won't since it's a spin off. So no matter what happens, Twilight will never remember it. Maybe she will be brought back and she will have forgotten everything. Because that's just how it is, it's a spin off, it won't become a part of the show.
