Kingdom Hearts Theory: Sora's Fate

Obviously, spoilers for KH3 Re:Mind ahead so... yeah.

Hey guys! I wanted to talk about this for a while, but couldn't really think of anything. If you don't know what I'm talking about, I'm talking about Kingdom Hearts 3's ending for Re:Mind.

If you don't know, there are 2 endings for the brawl between Sora and Yozora. The bad one has Yozora crystalize Sora and promise to save him. The good one has him fade away as he says his powers aren't needed for now. What happens next is the same: Yozora wakes up in a car and we hear Sora's first line shared between the two:

"I've been having these weird thoughts lately. Like is any of this real or not? None of this... makes sense to me"

To answer what the endings mean, we have to look at where the fight is happening. We see them in the Final World (basically purgatory) and then they are put on Sora's Dive to the Heart which is transformed digitally to look like Shibuya. Yozora also tells Sora that he's not really Yozora and he has gone through trials to save Sora, especially as the ending shows him as Noctis from Final Fantasy XV with who's likely Luxord as the driver.

So... what does this mean? Well, I have an idea:

This is that Sora is forced into basically be like Ventus to Noctis/Yozora. In other words, just like Ventus, Sora's heart is heavily damaged while at the Dive of the Heart, so it's forced to stay with another's to keep himself alive. Now, what do I mean? Luxord likely put Notis, the "Commander", on the path to save Sora. How? Let's just look at what it shows. Since Shibuya seems to be fabrication of a world used in a dream to train someone through trials... sounds familiar. Wait. That's Dream Drop Distance again! So he's either digitized for training or dreaming with it being manipulated, which both being possible (Data Twilight Town and DDD).

Then what's the card Sora got? It's probably a beacon of sorts. That was how Yozora could find Sora. Luxord is a gambling man and has been shown in the other games to move his own chess pieces to make his own profit. Either way, I think it ends up with Notis having Sora's heart trapped in him to keep him safe intending to save him eventually. Another possibility is that Luxord knew how Roxas was a natural with the Keyblade because of Ventus, so he may have gotten Notis to do the same to Sora to be a better fighter and, well, Commander.
