Well. If you only see the pics you start to believe that Sai's betrayal was fake, because you only see Yamato arriving with Naruto and Sakura.
Naruto bitching like always.
Sakura handing the book.
And Kabuto returning in a matter of "I will find out their traitor is in fact a deciever"

So... reading the translation trashes this bad theory... thats the spoiler

PS:
Ok ok, lame excuse of mine.
