"The Great and Powerful Trixie is getting married!" ...Or is she?
April Fools! Yes, as realistic as this image appears, I'm going to leap to conclusions and assume it's another fake. After all, we have some very talented artists on the web capable of creating fan art in the exact same style as DHX Media. Since according to the Derpibooru site that there is no original source for this image, it's more plausible that some user made this and tried to make it convincing by slapping on the Entertainment Weekly text logo. There's a number of reasons that this can't possibly be a future Season 4 episode for a number of reasons.
1. First and foremost, Season 4 is assumed to be still in production and since it's coming this winter, no site would give away sneak previews this early.
2. As much as this makes a nod to the fandom in the sense of Trixie and Twilight shipping, the show would never show anything gay or lesbian, even though the world should be more aware of it and respect it.
Now it has been said that Trixie will return at some point in Season 4 and even though the events of the Season 3 episode "Magic Duel" suggest that Trixie actually has a good heart and means no real harm as a unicorn, I'm still not buying this... unless Trixie's marrying a handsome stallion somehow. But no. So here's our April Fool's Day prank for 2013. Over and out.
