Hi, I need help finding something in SF

So it’s just a one liner dialogue, kinda like this text I provided up top… but I’m looking for a page where Cassian calls Nesta a brat, and then she throws back at him: “brute”. I did a reread recently and found it hilarious, and I thought I had marked it, but I can’t seem to find it in my annotations :/. If any of you have it marked/any idea of where in the book this might be said, it would be much appreciated! Thank you.

PS: sorry for such a random small request in the dictionary sized book🥲
