Absurdly, Cosima wants to smile at how much Avery reminds her of Sarah in that moment. (She resists the urge - it would be unkind, especially without the context.)

Instead, she says, "I guess. I mean, you're the expert on you, right? But for me, I'm thicker-skinned than I look, that's all."

In fairness, Cosima knows she looks less "tough" than "semi-convalescent" at the moment.
