Peter Quinn (Rupert Friend)Mysterious and taciturn, Peter Quinn (Rupert Friend) is a CIA operative who joins the Brody taskforce. Both Carrie and Saul are unclear about what Peter's true motives.

Peter is extremely intelligent and dedicated to catching bad guys. He often clashes with Carrie who does not like taking orders from him. And while he might not always agree with Carrie's unorthodox methods, he has immense respect for her skills as a CIA agent.
