When we last saw Tyrion, he was spitting righteous vitriol at his trial. The seventh episode “Mockingbird” shows a softer, more introspective man: basically, he knows he just signed his own death certificate and merely wants to make amends before his trial by combat. He admits to Jaime that he fell in love with a whore, and he chose not to cooperate with the deal Jaime made with their father out of spite. At his most powerless, Tyrion was still able to take away some happiness from Tywin, who was thisclose to having Jaime back as his heir. Tyrion goes on to tease Jaime about his foibles and penchant for incest, and oh, by the way, Jaime, will you be his champion?
