Itachi has been helping Sasuke

Reasons why:
(borrowed from my friend)

IF YOU LOOK AT THE LAST PAGE of the latest chapter; "Forgive me my brother, for pushing you"

• he was protecting Sasuke from Madara
• he wanted him to get stronger and stronger
• so when Madara came after him, he could fight him

• on this last fight, he was showing Sasuke all the jutsus...since the SHARINGAN can copy them

so when Madara came after him, he could fight him

• I mean, when they were younger (Sasuke and Itachi)...Itachi always told his dad to watch Sasuke because he knew Sasuke could grow up to be stronger than he was
• When Sasuke "gets his eye ripped out" Itachi said "Forgive me brother" he obviously feels sympathy and was pushing sasuke hard.
  

Suigetsu is Sai's Brother



FOR ONE! LOOK AT THE PIC!!! on the left is Sai's brother, on the right Is Suigetsu


And there, notice how Sai's brother has no glove covering his Index Finger or Thumb

• Kisame mentions Suigetus has a brother, and Sai has a missing Brother.

• Suigetsu Collects weapons, just like Sai and his brother did in the book.

• In chapter 356 we finally see Suigetsu's hair color...and guess what!??! it's white! Like Sai's brother. In the manga, Sakura says "The *white haired boy* has the same kind of story."
• People in ROOT adpoted a training program from the Hidden Village of the Mist. Suigetsu is from there. It's been stated that Sai's brother isn't related by blood, but rather someone close to him in ROOT. Perhaps Suigetsu was drafted into ROOT or something like that, since it programs were adopted from the Hidden Village of Mist.
  
  • Sai states "You two are so alike, you and my brother. I mean... he was loud, impatient and unrefined.... and his peni... well it doesn't really matter." and Suigetsu is just like Naruto
• Sai's Brother got sick and they presumed he was dead. Maybe Orochimaru took him away for experimentation. Also, his origins and how he came to be at root can be explained.

Other stuff:

Pein, who now is discovered to have multiple bodies, could have used the remains of Obito to reconstruct the body and revive Madara in the body of Obito, which contained Sharingan only within the right eye, the same eye that Madara has been shown using the Sharingan. It is also possible that Pein employed Kakuzu, who was able to reattach Deidara's arms after they were severed, and could have done similarly with Obito and Madara. One more speculation is that Orochimaru, who was able to use the Summoning: Impure World Resurrection, as demonstrated in the fight with the Third Hokage, and who was once a member of Akatsuki, probably used or learned it there. And so, it is possible that the body of Obito has been reanimated and the spirit of Madara has been implanted into him using another forbidden jutsu.
