Lets put this to rest........sasuke has tskyomi

[Mischeif Maker]

here itachi says that susanoo awoke along with tsukoyomi and amaterasu on that fateful day. It doesn't say that you must have tsukoyomi and amaterasu, itachi just said that in his case susanoo appeared with these 2 techniques.

sasuke says here that you need to control the double mangekyou to have susanoo. He doesn't say that you need tsukoyomi and amaterasu. Besides, he obviously cannot control tsukoyomi so how can he control the double mangekyou?

data book says you need both.....data book know more then you.....quite being a fool if all you needed was the double then shisui would have had it but he didnt but he had the double.....guess that means the data book is right eh
