TO NO END. Gawd Derek. You are one of the worst patients she's had, and she's treated Tony Stark and LOKI f'gods sake. He's sassy but not an utter ass and as irritating as it might be, she does appreciate the snark. It's a bit of a defense mechanism more often than not but it's developed into some friendly teasing at this point. He's a patient that's an associate that she remembers thinking of kindly, and is slowly growing fond of. She trusts him a bit, but it'll take more time for her to trust him fully. Right now he's kept at a comfortable distance.
