Orochimaru...after what's happened I don't blame Kakashi for being pretty alert. Sakura, on the other hand wouldn't be sure if the Sound Nin would have anything to do with this incident but then again, seeing them later on will make things more clear in terms of the bigger picture still remaining unclear (and needing more investigation as well). At any rate, I don't see it taking us too long to get to Tanzaku where the action is and then of course gives us more room for some fun combat.
