Roku your just rewriting what we already know. Give us something new, something we don't know like:
1) Is the Rinnegan connected to the elder brother or just a mutation?
2) If the rinnegan is a doujutsu passed down by the elder brother can it also decode the secrets Madara was talking about?
3) if there is a connection would that mean Uchiha & Huuga are distent blood relatives like Senju & Uzumaki?
3) And would a new doujutsu emerge if Sasuke knocked up a Huuga? ...Well if Sakura doesn't murder the poor pregnant women.
