YO!

This can work. Kabuto can kill Taro while he's weakened to confirm that Orochimaru is indeed involved, as if the Sound ninja did not make that obvious enough. I think by that point it would be much too risky for Kakashi and Sakura to attempt to apprehend them, so Kabuto will suggest they simply go their separate ways. Taro is tutorial so yeah he might send the fodder first to soften them up and deduce their strengths in the meantime. He'll probably go for Sakura the hardest. I also want to set up Kabuto as a constant 'boss' for Sakura to deal with as she becomes stronger and stronger. Kakashi can even be fooled by him, so he's a pretty serious foe.
