 * 1) We don't know what the attack would have done if it had hit her. She might just have been frozen solid like Natsu was after punching Crawford's teeth out.
 * 2) He might not have recognized her, because she died in childbirth or when he was still too young to remember her face.
 * 3) There is no guarantee yet, that Juvia will be the mother of Gray's children.

Not that I really think Silver will turn out to be Gray's son, but it is not yet impossible.
