Quote #7
BERTIE: Those are my wishes, Your Grace.
Bertie insists that the archbishop listen to Logue's demands because there's nothing more important in Bertie's life than speaking well. He doesn't care what class lines he has to step across. He needs Logue's help more than he needs Lang's approval.
Quote #8
BERTIE: No, it's not, that is Saint Edward's Chair!
When Logue sits in St. Edward's Chair, Bertie finally snaps. He's willing to let certain class differences go, but to let a commoner like Logue sit on the chair that's reserved for monarchs of England is just too much for him.
Quote #9
LOGUE: I don't care. I don't care how many royal arses have sat in this chair.
Logue is clear about what he thinks of England's division between royalty and commoners. To put it simply, he doesn't think highly of it. But he's trying to get Bertie's goat here because he knows that Bertie will never improve his speech until he realizes that it's not his royal birth that entitles him to speak. It's the fact that he's a human being.
