Jesse and Fiona work together on the episode "Breach of Faith." In this Burn Notice clip, the pair pose as newlyweds and try to get the home address of the person they're after. We get a good idea of Jesse's smarts, as well.
James: What we do here together, what we stand for. Do you believe in it? And don't give me the answer you think I want. What I want is the truth. Michael: I have always agreed with your methods, but the jobs I've helped you with, the ones no one else was willing to do, they needed t be done. We protect what is important. You made me part of something that is bigger than you, bigger than me. You made me believe there is something worth fighting for, something to believe in.
