When they arrive in Islamabad, the mosque — reputedly the largest in the world — captures Sohrab's attention. Before Farid leaves, Amir gives him an envelope of money, and then never sees him again. Amir falls asleep, and when he wakes up, Sohrab is gone. Eventually he thinks about searching at the mosque and gets the clerk from the front desk to drive him there.
When they find Sohrab outside the mosque, Amir sits down next to him, and they talk. After Amir says that Sohrab must miss his parents, Sohrab asks whether Amir misses his. Then Sohrab admits that he is beginning to forget his father's face. Amir gives Sohrab the Polaroid photo of Hassan. Sohrab then asks Amir if he thinks God will put him in hell for hurting the bad man. Sohrab is concerned about disappointing his father. He then says that he is full of sin because of what the Taliban men did to him.
Amir asks Sohrab whether he wants to go to America with him. And a week passes before the topic is mentioned again. While talking, Amir admits to Sohrab that he and Hassan were half-brothers. He acknowledges that Hassan's being Hazara was the reason for the distance between the two. Sohrab admits to being scared about the uncertainty of their future together: What if Amir's wife doesn't like him? What if they tire of him? In response to his concerns about going to an orphanage, Amir promises him that we will never need to go to an orphanage again. Sohrab nods in agreement after Amir implores him to "Come home with me."
