TAV did not die, do you have any proof.
Aside from what Xigbar said.
Yeah i was referring to LS
Though im not 100% sure on that im just saying i think he did.
Id like to say i dont think VAT is dead
Yeah, the only way that they're alive is if they no longer have the ability to wield.
Aqua might live on in someone like roxas does in sora
No.
Terra maybe but someone we know.
Them being dead i highly doubt
Them being dead is the most likely of situations. There is only one other explanation and that is they no longer have the ability to wield Keyblades. Though this conflicts with one of the themes of BBS:
"Xehanort appeared when the people with the blades of keys disappeared."
The likelihood of them being dead seems to be a majority percentage; like 98%.
