I'm hearing this everywhere on Fimfiction, Equestria Daily, YouTube, DeviantArt. They say at the end of Season 3, Twilight's gonna be an alicorn like Celestia, Luna, and Cadance. I have no idea if this is real or just another trollish rumor like Derpy having her own episode.

Does anyone here know is this is real or not? Because I am really, really confused right now.

Sigh if you look at the synopsis for the episode, then it makes far more sense. It probably is real but she only becomes one temporarily until things are fixed in ... oh say? 22 minutes.
