The Kingslayer is still sword-training with Bronn, this particular session ending when Bronn steals Jaimes right hand and knocks him to the ground with it. As they take a break, Jaime asks Bronn if he thinks Tyrion killed Joffrey. Bronn doesnt think so, admitting that while the Imp hated the king, he wouldnt murder him. Realising that Jaime hasnt gone to see his brother yet, Bronn recounts how he met Tyrion, stating that Jaime was Tyrions first choice to stand for him in the trial by combat as the Eyrie, Bronn being his second. Realising hes put the visit off long enough, Jaime goes to see his brother in prison. Tyrion maintains his innocence, but realises that it doesnt matter since everyone already thinks hes guilty, not to mention that Tywin and Cersei would like to see him out of the way. Jaime admits that Cersei asked him to kill Tyrion, but obviously wont do it. Jaime offers his help, but Tyrions only wish is to be set free, and Jaime wont commit treason. He also states that Cerseis offered a knighthood to whoever finds Sansa, who Cersei believes is Tyrions coconspirator. Jaimes in quite the predicament. Hes been the only family member in the Lannister family whos treated Tyrion decently, so hes more likely to believe his innocence. On the other hand, hes not willing to break the law to help Tyrion, especially in his role as Commander of the Kingsguard. He may try to help Tyrion in ways that hes legally able to, but for now, hes not willing to take any risks for his brother.
