I think the thing that gets me most about the Nightmare’s End/Mirage Split keyblade is not just that the keychain becomes a paopu fruit or that two halves of a heart fuse into one, but that it would have been so easy for them NOT to have made the keychains turn into a paopu fruit. I mean, look at the designs for the keychains of Sora and Riku’s separate halves:
How EASY and logical would it have been for them to just use the same heart design but use both wings on the combined keychain, and no one would have thought anything of it? But no. They actually sat down and chose to transform them into a paopu fruit.
