Chapter 13 - 15 TKR

I find it ironic that Amir and Soraya can't have a baby. It almost seems like one of the punishments for Amir betraying Hassan. There's no way the author didn't intentionally make that happen. I was suprised when Amir agrees to go to Pakistan for Rahim Khan. I realize that he was a mentor for him when he was young but from Amirs past, he is not known to be a risk taker or to be proud of standing up for something. Maybe he's finally growing up and wants to find redemption for what he did to Hassan?
