The part where Norrell risks his standing to TELL THE DUKE OF FUCKING DEVONSHIRE TO SHUT THE FUCK UP.

Hell yeah! I don't think Norrell even considered that he would be risking his standing. He just can't believe that someone would talk over Childermass when Childermass clearly knows so much more than them and is saying something interesting. I can almost see Norrell's annoyance at the whole thing. He's like, "Dude, what do you think you are you doing? Childermass is speaking."
