It's a fascinating question, though, isn't it? Thanks so much for taking the time to contemplate and explain! I don't really like to ponder the eventual ends of the different versions of them I have, in some ways. It's hard to make it work out just right, you know? I think I often tend to assume that my versions of them die together, facing some major foe...but I don't think I've ever written that because it's such a painful thought.
