After the trial, Jaime visits Tyrion in his cell, and the two fight over the stupidity of Tyrion's outburst. Jaime argues that he made a real sacrifice in initiating the deal with their father while Tyrion points out that in doing so he gave their father everything he ever wanted — the exile of his impish son and the potential grandchildren holding the Lannister name. "It felt good to take that from him," Tyrion says.
Tyrion then expresses his desire to have Jaime as his champion in the trial by combat, making a joke of the idea that their father wouldn't allow both of his sons to perish. "You're the golden son. You could kill a king, lose a hand, f*ck your own sister — you'll always be the golden son." Jaime bristles and responds he's unable to act as champion since he can't adequately fight with his left hand. Tyrion then asks if Bronn will once again undertake the task, but the sellsword's allegiance has been bought by Cersei. Fortunately for us all, Jaime hasn't given up on his little brother.
