_Sai and Ino fight with Marige (the medic nin) and some other person that have drank the medicine that give them power somewhat like the tail beasts. On the other hand, Sakura lead Kido into the forest, to fight him alone there.
_After they have killed all the enemies, Sai and Ino met up with Kakashi, Naruto and Hinata to go for Sakura, to find that Sakura has already beaten Kido (This allocution is very impressed, because Sakura is way too badass, the fight is really great).
