Ethania

Well, I believe that Roxas is in love with Xion. There isn't any evidence, but he did shed a tear when Xion went back to Sora. Then again, anybody would cry if their best friend left pretty much, died. I love reading Xion and Roxas fanfics though, but as the name suggests, it's fan-FICTION! I dunno, it's most likely a maybe. Also, nobody's do have emotions, it's just that Xemnas told them that the didn't because he wanted to make them all, Xehanorts vessels. You'll get it if you play KH 3D Dream Drop Distance. Oh and yeah, anybody or anything could grow a heart , if it/they don't already have one.
