I meant the half-pony transformation. Hmm, I'm half-tempted to call it a harmony transformation, but the sirens had similar ones, except with their fin-wings.
But anyway, Sunset has a pony transformation now, meaning she's at full friendship power!
And I only partially know why human Twilight will need a friendship lesson.
But I'm sure she'll need one.
I mean, hey, without telling you any spoilers, think about this: she's never met the other five, since, like Pinkie said in the first movie, she doesn't attend Canterlot High. She lives on the other side of town and goes to a different school. You have to wonder if she has friends, and if she does, what kind of people are they?
