The Demon in the Snow

is episode 19 of the original Naruto anime.

Plot
Gatō and a large group of his henchmen arrive at the battle. He provokes Naruto by kicking Haku's corpse, and Naruto yells at Zabuza because he did not get angry when Gatō kicked Haku's body. Then, Zabuza asks Naruto for a kunai and Naruto throws him one. Images of Haku flash on the screen. Next, Zabuza catches the kunai in his mouth. He charges at the group of henchman and cuts through them, reaching Gatō. He then slashes Gatō in the chest to death (in the manga, he decapitates him), telling Gatō that they are both going to Hell. Afterwards, it quiets down. Suddenly, the remaining henchmen realize that they still outnumbering the others. Kakashi clones himself to intimidate them, but it is not needed, as the people of the village arrive, and force the henchmen to give up. Zabuza asks to be laid by Haku's body, seeing his face one last time. The episode ends with it starting to snow, and Naruto and the rest of Team 7 standing at graves they made for Haku and Zabuza, then leaving the village.

Naruto states he will go to Iruka Sensei to treat him to Ramen for succeeding in the mission, while Sakura decides to go on a date with Sasuke. Of course, Sasuke declines the date, and Naruto goes and ask Sakura if she would like to date him instead. Sakura angrily declines and the arc ends.
