I know this is probably captain obvious but it's just so apropos imho.....
Jimmy, who Chuck regards as an incompetent lawyer, completely played Chuck like a fiddle on the stand. Even when Chuck condescendingly would see through what Jimmy was doing - it was intentional that he would see through it and played right into the next step of the plan. He was so overconfident and smug.....that was gold.
Also...The way Chuck overanalyzes everything (remember him rehearsing his testimony and the amount of time he spent figuring out the error on the Mesa Verde thing) he would have to reflect on this and see he was outplayed completely. But he probably won't he will go down kicking and screaming. That's what will probably end Hamlin's support.
