I was just going through ideas and theories on Sasukes rinnegan, and their seems to be alot of people also wondering about it, like for example why does he only have it in one eye, why does it have tomoe in it, was it hashiramas chakra or was the sages power, so i am going to throw a few possible answers to these questions.
As to why sasuke only manifests the rinnegan in one eye: Sauce-man could possibly have another rinnegan but has yet to show it kind of like when naruto only manifested a part of his power at first when he got his sage power up, also sometimes sasuke and other sharingan users manifested the ms in only one of their eyes even though they have an ms in their other eye aswell, sometimes they did it because they only were going to use the technique that the eye in that specific eye (like itachi activating his right ms for amaterasu), this could also suggest that sasuke tele whatever tech is only one part of his power and that the other part resides in the other eye. If rinegan techs work like this it could be the reason why madara really is in need of another rinnegan.
His rinnegan could have tomoe in it due to the additional yin energy that he was given by the sage. or maybe to make up for the fact that he apparently lacks a second rinnegan (but he could in actuality have a second rinnegan).
But yeah that is all. and oh if anybody has anymore theories about this than please post it.
no bashing.=D
