In this episode you will see Haku in the forest collecting herbs for her master and spot upon Naruto passed out. But don't worry, he doesn't harm Naruto in any way.
It was kind of shocking for me when Haku turned around before leaving the scene and said that he is no she. Kind of creepy because he sounded and looked like a female rather than a male.
Anyway, Zabuza will return at the end of this episode with Haku on his side. Naruto will be left behind in this one as he spotted some thugs taking on Inari. Watch the next episode to see the solution of Naruto and Inari.
