Forum:A theory as to why Van had "a way to dawn"

Ok I've been reading the Kingdom hearts wiki for awhile now trying to understand why Van who looks like Roxas/sora had picked up Riku's key blade instead of the sora's keyblade. I think the reason for this is because Sora was the one who was supposed to have "a way to dawn" not riku. Anyone who has played the first KH game knows that riku was supposed to be the master of the key blade, which leads me to belive it was sora who was suppose to give in to darkness and gain the soul eater. But because Riku gave into darkness he and Sora switched fates. Now I think something happens in BBS that causes the hearts or something else of Ven, Terra, and Aqua to go into Sora, Riku, and Kairi. This would explain why Riku had the kingdom key first(because Terra had it). This also makes me believe that something happens to sora in BBS that causes his orginal heart to dissapear or something which then Van gave his heart to sora to save him(or not). That would explain why when sora lost his heart that his nobody Roxas looks like a double of Ven(because it was Van's heart in sora's body or Van became part of sora some how). This enforces my theory that because Ven could have been part of sora, and because he had "a way to dawn" that sora really was suppose to obtain soul eater. I also think this could explain Xion. When Aqua's heart merged with Kairi it caused kairi to gain a combind heart like sora/ven had. So when Kairi's heart left her body the first time it created a nobody of Aqua(which would explain why they all look alike)called Xion. Then when Kairi's heart and sora's heart left sora's body it caused the creation of Namine and Roxas(but because it was Ven/sora's heart the nobody took on the looks of the part of sora's heart that was Ven's). Another reason I belive that Xion is Aqua's nobody is that fact that Xion and Aqua look very much alike while Namine ages and looks alot more like Kari(the fact that Namine is comfirmed to be Kairi's nobody made me think that there is another person that had been existing in Kairi's heart, A.K.A. Aqua)This also shows why Xion could wield the keyblade(which I belive she was also shown to wield Micky's key blade at least once, which was the one Aqua had). Finally I think that Aqua might still exist in the room of awakening in some form because Xion has real feelings which it seems that only nobodies who's original bodies still exist have. And Finally I belive that Terra's some how part of Xhenort which is why he wanted to posses riku(to gain the peice of his heart and powers that he left inside Riku.)I also think Terra's deep freindship is the reason his nobody Xhenort calls Aqua's armor freind. Also I belive since he left part of his heart in riku that is what caused his memory loss of every but his name.

What do you guys think?
