Max assists Virgil in bugging Nick Brody's home. When Carrie observes that he isn't Virgil's usual partner, Virgil says that he has to use him because Carrie is paying less than the usual fee. Max finds large, blue pills concealed in an aspirin bottle in Carrie's bathroom and shows them to Virgil. (Unknown to Max, they're an antipsychotic medication.) He later assists in eavesdropping on the meeting between Nick and Helen Walker.
Max was later assigned to the CIA station in Islamabad, where he served under Sandy Bachman and Carrie Mathison.
After Carrie returned to Brooklyn and brought Quinn home to live in the apartment below hers following his near death experience after the sarin gas attack in Berlin, she asked Max to keep an eye on him while she went to work. When Quinn left his apartment to go shopping, he suffered a seizure and having asked not to be taken to hospital, he asked Max not to tell Carrie what happened but he did so as he was worried.
Personal life and relationships
Max is the younger brother of Virgil. Unlike him he does not inherently trust Carrie.
