I'm okay with Twilight Sparkle becoming an alicorn actually. (I'm probably gonna get a lot of hate for that...) She was basically the main character. We saw some Sneak Peeks at Season 4 and saw Twilight as an alicorn in 2 different scenes. I think there's a good chance she will be an alicorn in Season 4. I for one am fine with that. (Apparently a lot of people dislike Twilight as an alicorn.)
