my new theory
what if a person can have two hearts that would explain a lot :
1. Sora has his heart and vens thus creating a special nobody that has a heart (Ven's heart is in Roxas and
Sora's original heart is in him)
I'm not exactly sure if this is/ was true, but I do have some feeling that at least a part of Ven is infused in Sora's being, be it his soul (because Ven probably died.. lol..), his heart, part of his heart (Which might be why Roxas makes Axel feel like he has a heart, why it was slightly hinted, but yet, he also is said to have no heart. Basically, why he's hinted at having a heart, but yet, believed to not have a heart. A partial heart would account for both the partial emotions Roxas
instinctively felt ("like my heart belongs to me")) and his lack of emotions, at the same time.), or his body (I doubt this the most though.).
2. Kairi has two heart her original and a heart of pure light (i dunno from where she got it maybe AtW did something to her) thus making 1 special no body Namine (with her pure heart)
and Xion with her another heart.
Uhh.. no.. though if she does have any heart or remnant of a heart in her, my money is on it being Aqua's, though I know the notion is frowned upon, especially by SA.
One half of your theory might be right/ partially right, but most of it's most likely wrong. Like some/ the others, I'm leaning more towards the Ven/ Sora half than Kairi/ Aqua/ other character (Did u c what I did thar? Yeah.. I'd much rather that if this somehow is the case, it's not Aqua.)
Oh, and I know spli/ partialt hearts is mostly/ almost completely disbelieved, but if BH's/ SA's theory holds some truth, maybe there's other ways to split a heart and more importantly, maybe a split/ partial heart is possible.
Kairi has a heart of pure light and I don't think the two heats thing is possible.
Now, I know this was already shot down before in the thread, but I just had to do it myself.
One person..
Sora (in most of KH1).. that is all..
If Roxas had Ven's heart in him, wouldn't he basically be a reincarnation of Ven instead of Sora's nobody? It just doesn't make sense to me.
Uhh.. no.. If it were to be Ven, it would be Ven's heart,
body, and soul. Roxas is made up of
Sora's body and soul.. and potentially Ven's heart or part of it. (given that the
"erasing" process has to do with the heart and the memories it holds..)
By the way, the reason why I consider the heart being involved in the erasing process is the fact that the heart has to do with memories. I may not have played Re: CoM just yet, but..
Marluxia told Namine to erase Sora's memories. My point is that "erase" was mentioned and it was about memories, which are supposedly tied to the heart, therefore, maybe the "Erase" Ven mentioned is one in the same with the erase that Marluxia mentioned.
