I don't really know where to put this since it's about Lea and Axel so feel free to change the location of this thread if you please. I also don't know if there's already a topic about this. So here goes:
The real reason why Axel is so close to Roxas is not because Roxas made him feel like he had a heart but it's because of the friendship of Lea and Ventus. He must have remembered their friendship with Ven when Axel saw Roxas since, you know, they look the same. I mean, Isa said that "at least we won't forget you" or something like that(look for it in the thread with scans of Lea and Isa). About Saix, I think he forgotten or probably got jealous with the Axel+Roxas/Lea+Ven relationship that's why he is so harsh to Roxas, or maybe he has a really serious and harsh nature, but we'll find out what Isa's nature is when the game comes out.
