SilverShadow

Cadences wasn't always a Alicorn, she was a Pegasus and she does have Shining armor eyes. It could be a future Episode again like they did with Twilight and her future self. When have you seen a series that quite a few years have passed since the last time we seen the main characters, a lot. There is many possible aspect to this whole season, but we do know we get to see nightmare moon again.
