So, if there is a parallel dimension...
... and all the ponies have their human counterparts, where did human Twilight Sparkle go? It was a breif mention by Applejack that TS seemed familiar, indicating there was a human-TS too. But I just can't figure it out.
- Where is human-TS?
- Did TS replace the human-TS?
- If human-TS exists, 1) shouldnt she attend to same high school?
2) why didn't the others recognize her? 3) would she also be a important character in that dimension?
I think it's kinda a minor plot hole and the story would be more interesting if TS and human-TS actually met and tried to solve things togheter.
