Lose and win on remind is talking about when Sora and the guardians lose vs dark tower on the keyblade graveyard, the scene when we can read, darkness prevail and light expire.....
Remin win, is the rewriting of that lose.
I will attach a new more clarifying scheme/diagram, what fits better into..
Quadratum is a fictional world, we dont even know where it is located, or in what reality is located. that is one of the main reasons to make that diagram.
Before thinking about it, i think (NOT SURE) it can be coded into the BoP or may be into the Black Box, but i think its inside the BoP because MoM scene drawing a heart in the moon. Whats the point of Quadratum and Yozora if they have no connection with MoM?
And, what does MoM do into Quadratum if he have not connection with this world or with Yozora?
