"We cannot have a Maiden from Circle Midnight!" Norrell exclaims, as if this is entirely obvious and Childermass should obviously understand that this is a good reason. "Especially not a Widdowson! You know their reputation for associating with the fae! It is entirely the wrong sort of influence! What other choice do I have but to try and put a stop to it?"

He lofts an eyebrow at Childermass, and something about the tone says he already expects the man to disagree on some level -- it is faintly defensive, while still expecting Childermass to accept his reasons and do as he wishes regardless.
