I think if these children grew up, mated, and then had a child of their own, they'd form a superior human life form that would automatically make everyone else on earth look ugly. They'd rule the earth from the time they were born. Can you imagine the possibilities?
On the other hand, if by some bizarre freak of nature, Orly's child is somehow challenged in the looks arena, that's going to be one rough road. I don't think it's going to happen, though. Look at Brad and Angelina's kids - all three of the ones Angie bore look like mini versions of their parents. Lucky bastards.
