The first "full-circle" ending that is reached occurs with Amir's return to Afghanistan - he has returned home. Details reminding him of the way it used to be here bombard him from all directions. When Amir rings the bell of the big house in Wazir Akbar Khan", he hears no buzz; there is "still no electricity" in the area, just like it was in the old days. Amir passes an old hand-pump water well in the yard, just like the one he remembers at Kaka Homayoun's house in Jalalabad, where as a child he used to throw pebbles in to "listen for the plink". Once he is in the house, he sees a coffee table by the sofa, "the base...X-shaped, walnut-sized brass balls studding the ring where the metallic legs crossed". Amir recalls that he had seen a table exactly like that at a crowded tea shop in Peshawar, many years ago.
Another "full-circle" event occurs when Amir recognizes that the degenerate, sadistic man he has come to see is none other than his old nemesis, Assef. Assef had been a bully of epic proportions as a youth, leading a gang against the Hazara Hassan and sodomizing him in an alley as Amir, undetected, looked on helplessly. As an adult, Assef's evil nature has reached fruition, as he has joined the Taliban and taken the lead in outright mass murder in the name of ethnic cleansing. Now Amir is given a second chance to stand up to Assef, and although his steps are tentative, he is firm in declaring his intention not to abandon Hassan again, through Hassan's son, Sohrab.
A third storyline comes "full-circle" when Amir finally finds Sohrab, Hassan's son. The reunion with his old friend through the little boy is almost tangible, as when Amir takes Sohrab's hand and the child's fingers "(lace) themselves with (his)...(Amir sees) Sohrab in (the) Polaroid again, the way his arm (is) wrapped around Hassan's leg, his head resting against his father's hip". When Amir finds Sohrab, he receives a second chance to do right by his old friend. Amir did not have the courage to defend Hassan as a child, but as an adult he has the opportunity to redeem himself by saving the son (Chapter 22).
