He pointed Sora out as the origin for the girl, to differentiate the theories Diz brought up up to that point being that she came from Kairi. I personally fail to see why a difference in origin would merit a difference in structure, especially since then I'd expect Diz to go on about how Roxas was the one that was made up of basically nothing, or at least wonder what he was made up from if Namine took Sora's B+S.
Not to get into this discussion though, just pointing out that no, Nomura never really said Namine was made up of Sora's B+S - more said Sora was the one she came from instead of Kairi. What she really is made up from and the true nature of her existence were never truly explained.
Uh, this is a kinda long and off-topic explanation, so I'll throw it in spoiler tags. >>;
Nomura said:
"Essentially when a strong hearted person has their heart stolen, they change into a heartless, and on rare occasions their body changes into a Nobody. But in the case for these two, for Kairi's heart to be hidden within Sora, it took a special shape."
Grace Assassin went through an analysis of this small excerpt of text, using basic grammatical ideas (prepositional phrases and antecedents) to point out that "it" refers to "Sora's Body." If Sora's Body took on Roxas' shape, that would be normal. Special = Namine. It makes sense. =X Now, directly in his words so you can follow the thought process better:
[spoilers][quote=Grace Assassin]So let's take a look at that second sentence:
"But in the case for these two, for Kairi's heart to be hidden within Sora, it took a special shape."
The word “it” is behind most of the trouble here. What is the antecedent of "it”? Well, many assume it to be Kairi's heart.
But that is grammatically incorrect. "Kairi's heart" is in the prepositional phrase whereas "it" is in the independent clause. Because the prepositional phrase cuts in between the independent clause before the word "it," many people have that misconception that it=Kairi's heart (since “heart” is the closest noun that would be considered an “it.”). Plus, Kairi’s heart taking a special shape doesn’t really make sense in reference to special Nobodies, does it?
If we cut out the prepositional phrase to see the independent clause as a whole (which is fine), it reads, "But in the case for these two, it took a special shape." By reading the sentence as such, you can tell that the antecedent of "it" is in the previous sentence. So what noun could it be talking about?
The answer is "body." That is, the body ordinarily changes into a Nobody, “BUT” (used as a conjunction in the next sentence to refer to an exception) it (Sora’s “body”) took a special shape. When we read in it that context, the two sentences make sense grammatically as such:
Essentially when a strong hearted person has their heart stolen, they change into a heartless, and on rare occasions their body changes into a Nobody. But in the case of Sora and Kairi, Sora's body took a special shape because Kairi's heart had been hidden within it.
This is irrefutable. You cannot deny that Sora’s body is what took a special shape.
Now it’s a matter of deciphering semantics.
So what does he mean by "special shape" here then? How does Sora’s body take a special shape?
Let’s think. He says that, ordinarily, the body changes into a Nobody, which would be considered the original person’s Nobody. BUT Sora’s didn’t, it took a special shape. Sora’s body taking on the shape of Roxas, his Nobody, would be normal. Catching on? His vessel did not take the shape of his own Nobody, but as Kairi’s Nobody. Namine.[/quote]
He goes on to say how this follows precisely with what Ansem the Wise says:
"I believe that Naminé was born as a special type of Nobody when Sora attacked himself with the Keyblade, causing his and Kairi's hearts to leave their bodies simultaneously.
Naminé emerged as Kairi's Nobody… but the body and soul necessary to exist as a Nobody belonged to Sora.
[...]
Naminé is Kairi's Nobody, but came into being via Sora's body and soul. "
So yeah.[/spoilers]
Roxas being Sora's Nobody would indeed explain how he could have access to the Keyblade at all. Him having a Heart, most likely Ven's - an established wielder - would explain how he could use it.
Not necessarily, but it still does not say anything of the supposed fact that the Nobody of a Keyblade Wielder should be able to utilize a Keyblade. :\
Sora was a "Heartless" and he wielded just fine. XH was a Heartless but he's the likely explanation to Riku Duel Wielding in KH2. So such a thing was never stated, just that "basically, you'd need a heart in order to wield". And that's where he changed the subject in the interview because he was all but confirming Roxas had a Heart of his own.
Sora stopped being a Heartless when Kairi purified him. He never picked up a Keyblade while he was a Shadow. XH's memories would be the likely explanation, not the being himself, though the question of "Why would Xehanort's Heartless give Riku a fruity Keyblade" comes into question... *shrugs*
Regardless, you supposedly need a Heart to wield a True Keyblade, and Nobodies by definition are devoid of Hearts, so it stands to reason that the Nobody of a Keyblade Wielder would not be able to Wield. Judging by Roxas is a false comparison. That's all the thread is about, is it not?
