Theroy of Equestria Girls

[Icy Wonderbolt 34]

Now I think many people on this site liked EGs, but I thought of something that might be a reasonable idea for EG. What if in the new world that Twilight goes in there is already a Twilight living there, but when pony Twilight comes, maybe Pony Twilight's soul replace the new world Twilights's one. This may sound silly, but I think It's a good answer to a question.
