Sasuke was given at least one technique. Ms normally has three techniques, one for each eye and one that requires both. Sasuke has four at least. His blaze release is a MS technique. :| He awakened his MS after the truth but itachi transfered his MS techniques or at least amterasu to sasuke before his death.
I came to the same conclusion once. But there's one thing that's a bit dodgy.
First, the abilities Sasuke's MS displayed so far:
- Tsukuyomi; right eye
- Ameterasu; left eye
- Susano'o; both eyes simultaneously
Plus two more MS abilities. (I dont see either of the next two MS abilities as a true MS abiltity in the same sense as the first three.)
- ability to quench Amaterasu, right eye (something Itachi can also do with the right eye; and also something, I personally think, is basically Shape manipulation)
- Blaze release; Both eyes (first Ameterasu in left eye then Shape Manipulation in right eye)
This basically means that:
Blaze = Ameterasu (left) + Shape Manipulation (right)
The point is. If Sasuke did not have Amaterasu, then he would not be able to perform Blaze. So, Blaze could not be an inherent ability of Sasuke's MS if Itachi gave him Amaterasu. Sasuke without Amaterasu would leave him with only a weak
Tsukuyomi in the right eye, relatively speaking. And
Shape manipulation, also in the right eye, which is completely useless without Amaterasu.
And nothing in the left eye.
And, I think Blaze is merely a derived jutsu. The result of combining Amaterasu and Sasuke's mastery of shape manipulation. (he displayed his mastery with the manipulation of lightning). So, blaze is not a MS technique in the same sense as Tsukuyomi, Amaterasu or Kotoamatsukami. But rather a derived MS technique.
All of this points towards two conclusions.
1. That Amaterasu is an inherent ability of Sasuke's MS. Simply put, Itachi did
not give Sasuke, Itachi's Amaterasu.
2. Sasuke only has three truly MS techniques
Personally I believe that siblings of the Uchiha have the same MS abilities. And is probably part of what makes sibling's eye compatible for EMS.
And that Itachi placed a "one-time" trap, activated by Madara's sharingan, releasing a one-time amaterasu sealed within Sasuke. Which was accompanied by a MS with Itachi's design in Sasuke's left eye, something that has never reoccurred.
I hope this ends the confusion.
p.s. I guess this also means that I'm not an idiot

(according to the title). Thats always good thing to know.
