Roxas' dual wielding ability Edit

The "Story" section says that Roxas inherited his second Keyblade from Xion. I'm pretty sure at this point that's just a theory though; it's also possible that Roxas' sorrow reached Ventus through Sora, making Ventus' Keyblade available for Roxas to use. Is there any solid evidence pointing either way? If so, then I'd like it if someone could show me it. If not, then I think both possibilities and the fact that it is unclear which one is the case should be mentioned in the "Story" section. RadiantDarkBlaze (talk) 01:54, April 29, 2015 (UTC)
