I just watched the fight like 2 days ago it looked like kakashi was just just trying to help ino-shika-cho get there revange on them he didn't even you 5 moves all tijutus will what do guys think
Kakashi had to go out of his way to help Team 10 a bit but at the same time, Shikamaru got Hidan out of the way. It would have been much harder to deal with a tag-team don't you think? I don't remember much of the anime fight thought only the manga X_x
Hell no, kakashi can't take on kakuzu and Hidan at the same time, they both baby shake, kakuzu wouldn't even need to put his masked creatures into play.
Well if he didn't have to babysitting others, he'd just kamui both of them without waste any other chakra.
But plot no jutsu wanted Team 10 revenge and Naruto's new jutsu.
