I'm not sure what character development Asia had when Fafnir appeared aside from being mentally scarred, but at least with Akeno the whole volume 12 incident did bring them closer together. I admit that it's not character development but more relationship development though.

And I think the short story he was referring to was the one about Akeno's backstory in volume 15, I don't know what the other one is though.
