Now we have a better idea of the motives behind the members of team snake following Sasuke. Sasuke, of course, is using the others to get to Itachi. Suigetsu wants to get the seven swords from the seven swordsmen. Jugo wants to see if Sasuke really is all that Kimimaro said he would be. As for Karin...she just annoys me. I don't know if she has a motive other than being another Sasuke fangirl.
