Wow lots of people complaining about a few flashbacks. It's Haku and Zabuza, of course there are going to be flashbacks.
Anyway, back to the episode.
History repeats itself betweem Kakashi and Zabuza, only this time we have zero emotion from Zabuza. Which goes back to the very first time where his emotions prevented him from cutting down Kakashi because of Haku. loved the touch with the blood tears. Also had to laugh at but also praise how they fix up the sword, it sucks up blood and fixes itself.
Suigetsu and Juugo are really loose endsn aren't they? No one seems to know what to do with them now Sasuke has ditched them.
Next week of course looks great, Gaara's father is brought back along with the former Raikage and two ninja who have Kyuubi's power.
