Interestingly, the telephone conversation that Rahim Khan has with Amir is never fully quoted. Instead, in Chapter Fourteen, the action begins as Amir puts down the phone after this conversation that has made him so sure that he must go back to Pakistan. However, the one line of the conversation that is shared with us reveals the mixed motives that Amir has for going to Pakistan:
Come. There is a way to be good again, Rahim Khan had said on the phone just before hanging up. Said it in passing, almost as an afterthought.
Clearly, Rahim Khan, as an old family friend, is an important figure to Amir, but what this throwaway line signifies for Amir is that Rahim Khan new about his betrayal of Hassan all those years ago and also recognises the unbearable burden of guilt that Amir even now bears. Thus, Amir is tantalised and tempted by this "way to be good again," which is the real reason why he returns to Pakistan. He is desperate to make right what he did wrong so long ago.
