I was thinking having Sasuke kill Garra would really put Naruto into a tough spot and this all may end with the hero killing his best friend.

From some of the Spoilers I have read I can't tell if Tobi is mad at Sasuke or just informing him.

Last I think its going to be interesting to see how Sasuke plans on getting to Danzo. Rushing in is not his style and taking on everyone at once is crazy.
