Orochimaru's eye!!! So what if like, Oro takes over Sasuke's body? I mean we know how much Naruto hates Oro. Wouldn't it make sense if he got a chance to fight Oro? Maybe Oro takes over Sasuke and finishes Itachi off? I can picture Sasuke standing looking at Itachi about to die with his last breath. Then Sasuke makes a comment along the lines of what Oro would say. Then you see Itachi shocked as he dies.

So right when you think Sasuke's story is over, and maybe he returns to Konoha, Oro takes over and Naruto's hunt for Sasuke continues.

ooooo
