A Cry on Deaf Ears

is episode 128 of the original Naruto anime.

Synopsis
Naruto asks Sasuke if he is willing to turn his back on all of his friends in Konoha for the simple matter of getting stronger. Sasuke says yes and starts to walk away, enraging Naruto. Determined to bring Sasuke back to his senses and to Konoha, Naruto grabs hold of him and gives him an echoing punch. Sasuke, who appears to feel no pain at all from this, spits blood on Naruto's face, and Naruto resolves to bring him back to Konoha by force if he had to. Then Sasuke grabs Naruto by his shirt and easily punches Naruto several metres backwards with the power of his Cursed Seal, inflicting several times more pain than his own attack. Naruto attacks Sasuke but is quickly kicked back into the water, and gets one of his weapon bags stolen. He creates some shadow clones, which are easily defeated by Sasuke. Naruto tries throwing shuriken from a distance, but is no match for Sasuke's superior skill with the tools. Using the wire strings from Naruto's bag, Sasuke traps him tied up to a rock and ignites the wire with flames, scorching Naruto with a burst of fire.
