Kingdom Hearts II Wait a second... Namine was born, how?!?

I'm sure we all know Namine, and the fact that she's Kairi's nobody. I had always assumed she was born in the moment Kairi "lost" her heart and gave it to Sora.
However, I was talking to my boyfriend (also a KH fan) and he asked me how Namine could exist if Kairi's body was there the whole time. I was flipping around on http://kingdomhearts.wikia.com/wiki/Main_Page so I looked up the article on Namine. This is what it said reguarding her birth:

"Naminé was born when Sora stabbed himself with Ansem's artificial Keyblade in order to restore Kairi near the end of Kingdom Hearts. This made Naminé a very odd Nobody, born from Kairi's heart and Sora's body and soul. Kairi's own body never became a Nobody because her heart lacked darkness (since she was one of the Princesses of Heart), so her body and soul were never able to leave the Realm of Light and thus made it seem like Kairi was in a comatose state until she regained her heart. However, this means that Naminé was also born without Kairi's memories, only furthering her status as an unusual entity, and she and Kairi are incomplete without each other. And because of the fact that Naminé is formed from Sora's body, she has the power to manipulate his memories as well as the memories of those who are connected to him, prompting several others, even herself, to call her a "witch". She came into being at Castle Oblivion, found by the Organization XIII.

Ansem the Wise has stated in Report 9 of the Secret Ansem Reports that Naminé is not a true Nobody. It is unknown if this was his opinion (as Nobodies generally remember their past life) or a fact."

While at first I thougt this made sense, it was just not what I had heard before, after reading it over twice I had to wonder... if Namine was created from Sora's body and soul, than what was Roxas created from? You don't exactly have two bodies and souls lying around! And shouldn't that make Namine S O R A's nobody, then? I understand that she's connected to Sora, that makes sense, but how exactly was she born? Kairi's body, after all, was still there.

So my boyfriend and I have tossed around some ideas but not come to any satisfactory conclusion. How does Namine "exist"? When, exactly, was she born? And how was Kairi's body just laying around? Is this just a plot hole, or is there something we missed?

Anybody got any ideas?

 

I had what i thought was a pretty well thought out theory. but the more i read it the less sense it made, so i don't know. Lol
hopefully it will be explained in 358/2 Days.

 

It's a bit confusing, and I'm not sure if I really get it still, but I'll try to explain in the simplest way possible. Namine, I think, is the Nobody of both Sora and Kairi. She was born from Kairi's heart and soul, I assume, and Sora's body, I assume, but a new one was created for her. Roxas, on the other hand, was born independent of Namine. He was born from Sora's body and mind, while Namine was just born from Sora's body and Kairi's mind? Does this make any sense?

So I've kinda been wondering if Xion is the Nobody born from Kairi's body and soul. Like Roxas, Namine, and Xion are all connected. Maybe? Anyway, it'll probably be explained in 352/8 Days. Sorry if this didn't help.​

 

there is one flaw.she doesn't exist,she is a nobody,a very special nobody.i'm not sure how she is the nobody of kairi if kairi's body didn't fade and all that stuff.like the above poster said,maybe they will explain in 358/2 days.

 

As far as I knew, Namine was born when Kairi lost her heart. She was a special nobody because Kairi is a Princess of Heart. I was considering the fact that though Kairi's body didn't disappear, she had a Heartless. Maybe that is Xion. But Namine is a nobody, and she got to meet Kairi so they are now...whatever that would be. My thought was, if Namine was Kairi's nobody, and Sora needed Roxas to wake up, then how could Kairi still be around without Namine?

 

I assumed Namine was born when kairi lost her heart, but not until Kairi got hers back? *is confused*

Sry, im confuzed nao...
