Naruto and Sasuke are already exhausted by Haku’s relentless attacks. However, these attacks are becoming less and less successful, causing Sasuke to gradually begin to not only track Haku’s speedy movements, but also to react in time to avoid them entirely. Realizing that this is made possible by Sasuke awakening his own Sharingan, Haku intends to kill Naruto in order to use this as bait for Sasuke. At the same time, Kakashi is severely injured by Zabuza. Zabuza notes that he will soon die just like Naruto and Sasuke, but Kakashi has faith in them and their powers. Inside the ice mirror trap, Naruto discovers that Sasuke used himself as a human shield against Haku’s attacks. Naruto asks why he did it, but Sasuke himself doesn’t know how it happened. He laments that he didn’t have the opportunity to kill his brother before he died, apparently. Naruto, enraged by Sasuke’s loss, vows to kill Haku.
