[With an answer like that, you'd think it might provoke a noticeable reaction — shock or light surprise at the very least.

Is he actually surprised by Sarah's answer? Yes and no. Her reply is frank, earnest and blunt, and he wasn't expecting that — or at least not with that degree of sincerity. You can see it in his face even if his expression may not overtly read as such; it's attentive and softer than it was before, sharp edges dulled into something more contemplative and somber as he listens to her. So in that regard, yeah, he's surprised.

But in another, he really isn't. Bigby has to remind himself that he is talking to someone who immediately had her mind made up about him when they first met and called him out on it. In public. To his face. Self-preservation doesn't seem like it gets in the way of brutal honesty with her. She is a teacher, after all.]

And you're not angry with them. [His observation is delivered flatly, there's a musing quality to his tone.] Even if you don't care about the war, they did bring you here to fight in it, regardless of whether or not they agree with it. Don't you hold them responsible?

[These aren't accusatory questions, and he doesn't sound judgmental in the least when he asks them. Rather, he's more interested in trying to figure her out and get her to think about the answer.

And maybe he's also trying to decide how he should proceed, too.]
