It came to my attention a few months ago, but I wanted to point it out here before the second half of Season 6 started
Because when it does, Twilight will have been an Alicorn for longer than she's been a Unicorn, in terms of episodes. (In terms of time passed, she already has, and if you count the movies as episodes, she already has)
And forgive me for being a negative nancy, but something about that just seems wrong to me.
