Don't know what happened to Kakashi's hand. Probably he was attempting to help complete Naruto's jutsu? Looked like he injured himself.

Nothing much in this manga episode, though I'm curious as to how many strategies Shikamaru has thought up. I have to say his team is not the strongest or have the best fighters by any definition. But his team is the most diversified in skills and catching the enemies. Thankfully Kakashi is with them to add extra firepower.
