Yeah she... she knows exactly the kind of expression you're talking about.

Brigid Tenenbaum isn't the most emotionally expressive person in the world, especially when she's trying not to be, but there are still tells. A fingernail moving on the coffee cup. A tightness in her face and around her mouth that isn't just from being overworked. The way she's not quite meeting his eyes for more than a few moments at a time.

Except when she glares at him right now; that goes on for a lot of moments.

"I am glad that you find something funny in this."
