Sohrab will never forget his parents and he, therefore, will never forget his past. Amir's father, a wealthy merchant Amir affectionately refers to as Baba, loves both boys.
Hassan was actually Baba and Ali's wife, Sanaubar's, son and Amir's half brother.
He dies from cancer inshortly after Amir and Soraya's wedding. After being brought to the United States, he slowly adapts to his new life. Two of Farid's seven children were killed by a land mine, a disaster which mutilated three fingers on his left hand and also took some of his toes.
He rapes Hassan to get revenge on Amir.
Amir finds a kinder fatherly figure in Rahim Khan, Baba's closest friend, who understands him and supports his interest in writing, whereas Baba considers that interest to be worthy only of females. After spending a night with Farid's brother's impoverished family, Amir hides a bundle of money under the mattress to help them.
