I'm thinking Sasuke will run into Karin due to her sensing him with her abilities, which in my opinion could turn into an interesting little reunion. Will Karin still want anything to do with him or will she be unable to forget how he was willing to kill her in order to try and kill Danzo?
I personally think she'll still feel attached to him but won't go with him for whatever reason she has. Perhaps she's found that Konoha isn't that bad. Because if you remember she mentioned how "the village is warm and people here are friendly"
Either way, I think Sasuke running into Karin is nearly unavoidable. So is she going to dry hump his leg the second she sees him or does she have more common sense about men that have tried to kill you than Sakura does?
UPDATE: just realized the dumb typo in the title.... haha
