With a few summaries... Summary #1 In the previous chapter we saw Sasuke stab Itachi Obviously it was a genjutsu Then Itachi starts his Tsukuyomi Scene changes, Tobi arguing with Kakashi, Tobi and Kakashi talk. In that moment, Kakashi says a single word (or stops talking) Gives the feeling of "It can't be... You're...!" Summary #2 Sasuke: .... Itachi: Guu... As blood flowed out from his mouth, Itachi fell onto the floor. As he fell, his whole body started melting and turning to liquid, and a tomoe sign was formed on the floor. Sasuke: ?! The dimension collapsed, trapping Sasuke within...just as if Sasuke was swallowed, the scene changes to the battle between Suigetsu and Kisame... Water was splashed and scattered around. Suigetsu's body was pierced by Samehada and stuck onto the lamppost. Kisame: Well well, I thought you're pretty strong...a tearful face, that's it? That's such a kill-joy... Suigetsu: It's so nostalgic... A grinning Suigetsu. Kisame: ?? ....are you laughing at your own pathetic state...it's painful to realize the truth isn't it? Suigetsu: I got that from elder brother many times before, the feel of this blade... Kisame: Come to think of it, you're right. Your elder brother was called Houzuki Mangetsu, right, Suigetsu? (The former owner of Samehada...) Suigetsu: Alright...it's time In a flash, Suigetsu pulled out Samehada, turned to the slime form and landed on the ground. In his right hand, he held the cleaver (Zabuza's weapon), in his left hand was Samehada. Suigetsu went into a double sword stance. Kisame: Oh...My Samehada that rejects getting handled by anyone besides me is not resisting? Suigetsu: I'm taking this sword, Kisame sempai Kisame: If you can do it, that is... Suigetsu: It's neither to attack my brother's enemy, nor about thinking of what I want to do to a missing-nin like you. This time, it's purely for entertainment, that's all. As soon as he had spoken, Suigetsu's body started to swell and blister. The water took on a muscular form and flowed towards the two swords... Kisame: snake...!? Suigetsu: Suiton rehha - hebi guchi! (Suiton multiple waves technique - snake's mouth) Here I come...Kisame sempai!! Kisame: Fufufu. That's going to be entertaining for me. Kisame formed handseals. A huge quantity of water came crashing out from nowhere... Both were surrounded by sheets of water... The appearance of Houzuki Mangetsu was reflected in Kisame's eyes... The scene changes abruptly to the Itachi vs Sasuke combat, Itachi was sitting leisurely on the chair... Sasuke's breathe rose, he suddenly stood in front of Itachi's eyes. Itachi: Is this how I look in my death? Sasuke... Sasuke: ...what the...?! Itachi: I ask once more... What can you see before your very eyes? Summary #3 The Itachi who was stabbed by Sasuke is obviously a genjutsu, and Sasuke realizes it. Itachi explains the truth behind the murder of the clan (Madara did it). The purpose of Mangekyou Sharingan is the control of the Kyuubi, but as a risk your eyesight drops radically.
