In this episode, more questions are asked, but only a teaspoon of answers are supplied.
Subaru makes a wonderful come back in this episode, as she delivers a monologue that would have all your previous hate for this character melt away. Sora, whom was being set up to receive his end of karma. Just when you think he's turns to the right side, that glimpse is taken aback with a depressing notion.
This is not an entire project, just the prequel to end. Instead of asking the local questions, questions that you would never have thought an anime could provide are asked. Though answers are sparse, and located within either the games or another anime, you'll find yourself glad that you had witness the stone in motion. And that stone doesn't look like it'll be slowing down any time soon!
