I just caught up with the latest chapters. This is some interesting stuff.
However, Sasuke sounds like a major schizophrenic to me. From 'I won't hesitate to kill you' to 'Don't kill anyone' and then to 'How about I kill the both of you?'
And I'm wonderering why he needs the three of them. Karin, prolly because she can locate Itachi and maybe Suigetsu for diverting the Kisame guy. For what would he need Juugo?
I hope this arc doesn't get screwed up with too much cliches.
