Final answer:
Sohrab ends the fight between Amir and Assef by shooting Assef in the eye with a slingshot, which allows him and Amir to escape.
Step-by-step explanation:
The fight between Amir and Assef in Khaled Hosseini's novel The Kite Runner is ended by Sohrab, Hassan's son. He does so by using a slingshot to shoot Assef in the eye. This sudden act by Sohrab allows Amir and him to escape the situation, which could have been fatal if it continued.
Sohrab's intervention is critical because it not only saves Amir's life but also mirrors the way Hassan used to protect Amir when they were children, bringing the story full circle and highlighting the themes of redemption and courage.
In the book The Kite Runner by Khaled Hosseini, it is Ali's son, Hassan, who ends the fight between Amir and Assef. During the fight, Assef threatens to harm Hassan with brass knuckles, but Hassan refuses to back down, standing up to Assef to protect Amir.
In this act of bravery, Hassan uses a slingshot to hit Assef in the eye, causing him to retreat. While Hassan does not physically defeat Assef, his intervention stops the fight and protects Amir.
