Well, there could be a pretty elf sister or something. Humm. Or maybe the more magical folk of middle earth have figured out how to mix male genes together, but still have a woman have the kid? LOL

I am not a fan of mpreg, though the concept amuses me....
Or what if Leggy has a female kid though someone else, and that kids ends up with Aragorn's boy. That way the blood lines still mix about as early as possible. LOL
