Wow...umm...now for my deduction: Sho will eventually be Sesshomaru. Hinaku and Solyn are their children. (Hence why when she was in America she could past for their sister) There are 2 Kagomes because you have the one from the past that lived into the present and the one in the present. (Time is such a finicky thing) Since Sho will be Sesshomaru, Inuyasha is his younger brother. What has begun is the weird timeline of there being 2 Kagomes.
Now I wonder if when Kagome fell in the Blood Drinkers Well and since she lived into the present, the present Kagome will never be seen again because she has to remain in the past to live to the future and be kidnapped, meaning there is now only one Kagome and a semi-normal timeline...
and is that the reason why Sesshomaru had to hide them...because there couldn't be 2 Kagomes walking around the feudal era all willy-nilly...

Well, thanks for ruining it for anyone who reads the reviews. Lol. Are you in my head??? And the only thing left to now is rescue the older Kagome from Naraku. Sesshomaru is gonna kick some ass!!! ^_^

PS: I love time travel. Because I don't think you can change anything in the past, since it has already happened. That means I can do whatever i want with it. And I love Kagome going further back in time. It's lots of fun! ^_^

Love it so far. It's new and refreshing. I'm guessing the child is Kagome's and Sesshomaru's but from the future through the Blood Drinkers' Well. Love the story and can't wait for the next chapter.
