I think there are two points that may not have been considered here. the first being that vo's child may have been conceived shortly before he died rather than in the week he spent as a returned. if this is the case than I suspect whatever allowed was different about him, whatever allowed him to return when no one ever had before, is responsible for the changing color of the royal hair and the fact that the returned can alter their appearance is unrelated. secondly what other effects did lightsongs healing have on the godking? is he even a returned or is he fully alive now? even if he is still a returned might the healing have fixed whatever prevents the returned from having children?
