Thanks!This was one of my responses on how I think Roxas and Namine are siblings and that why thier relationship is well, gross
But they came from the same person.
And I have a therory about Namine and Roxas, because Roxas is Ven, I think Namine is Sora's nobody, like Xion was.
The reason?:Sora killed himself to save Kairi, making her the most important thing to him, I think a nobodys looks are based off who was most important to the heart's self.look at Larxene, Marluxia, Xemnas and all the other organization members!And that is why Axel and Xion seemed to display true emotion, because the most important thing to them was NOT themseves!
