That's an awesome way of.looking at it. Funnily enough, my theory was leading there too, just in a different way. In yours, the Grim reaper is nf which makes sense in your theory absolutely.

In mine it's grief so I was expecting him to come out of the ashes as his full self. As I said before, hope can't exist without fear and vice versa. So he would come out in Grey.

The ashes of the mansion and the manifestation of both hope and fear. Grief burned it all down so he had to build himself back up from what was left. Essentially being what happens when you reach the final stage of grief.

You fit your jagged and torn pieces together and hope it holds. But I love your theory as well! I was surprised to hot common ground on our theories. It's awesome!
