Since you brought up the prophecy Cersei ' s prophecy says that she ' ll die by the hands of her valonqar , younger brother . Cersei is the older twin . She ' s only a couple of minutes older than Jaime , so he is still one of her younger brothers . I ' ll add to your theory that , while Cersei is so obsessed with Tyrion being out for her blood , she won ' t notice Jaime slipping away from her . In that sense , Tyrion is more of a red herring . <| sep |> A girl had done that to me , she thought her husband and I were friends yeah right , the guy ' s a true asshole and we just work together . However , she tries to get me into dating her but I soon repelled away and moments later , she got fired for fighting with other girls I was like thank you god for firing that fat , ugly sack of shit ! .
