Hmm... I don't know if I'd call it "flying". Her wings aren't moving, she seems to be leaping versus actual flying.
but I'm not seeing the arch motion that goes with a leap, I think she could just be fluttering and not actually flying
It's hard to tell but it does look more like a jump than actual flight. But it could be a sign of things to come in which Scootaloo will actually fly in a future episode! That would make my day complete!
I examined it frame for frame. As much as I'd like to agree that she flew, the wings didn't move at all and there was in fact a slight arch as she traveled across the screen. I believe with her wings up, it helped her soar across the room and minimize the arc of a jump. Therefore, I've come to the conclusion that it was, in fact, a leap.
