On another thread, @DominusNovus picked up on something I had written about Ser Gregor winning the trial-by-combat over Oberyn Martell. Technically, as Cersei's champion, he was proving Tyrion's guilt as the murderer of Joffrey. But Oberyn had made the fight a referendum on Ser Gregor's treatment of Princess Elia and her children. So did Gregor "prove" his own innocence by winning the fight, even though he confessed to raping and murdering Elia? Does GRRM want us to draw a conclusion about
