So we all know TN Will so something to blow our minds in KH3 for sure but I did some thinking. My theory is, what if Sora has been a Heartless all this time? I mean think about it, ever since he gave his heart up in Hollow Bastion he could have never FULLY recovered. Maybe that could explain why Roxas still existed while Sora was alive. Also that could've made it easier for Namine to temper with his heart in COM. And thinking back to DDD being a heartless could've made it why he was such an easy target for Xehanort. Sure his heart is still partially devoid of darkness and he still FEELS. But maybe he's never been a full human since he returned from being a Shadow.
