If there's one thing Max has a razor set of ears for, it's mockery. Even in text. He saw it in Pyotr and he saw it in Fitz's 'admission' and it has him putting his communicator down and taking a cold shower for a while. Once he gets out, he puts on the shirt Justine gave him and he leaves a message for Doc Sheehan.

Do you need anything fixed? I'm good with engines.
