Season 1, Episode 18:

Identity Crisis

Fusco: Did you work an identity theft case?
Carter: Every arrest I ever made. They all say I got the wrong guy.

Reese and Finch are thrown for a loop when the latest number, Jordan Hester, winds up being the victim of an identity theft. Of the two people who could be their person of interest — a barman or a lady who deals in antiques — they have to figure out which is the real Jordan Hester and which is the imposter. At first it seems the man is the fraud and the leader of a drug production ring, but when Fusco investigates a previous victim of the same criminal he learns that it's the woman who runs the drug ring, and the man is trying to get to the bottom of who stole his identity. With help from Fusco, Reese and Finch manages to get the real identity thief arrested

Meanwhile, Carter is approached by Agent Donnelly of the FBI, who has been investigating the "man in the nice suit" who intervened on behalf of Powell after the congressman's assassination. He knows that Reese was once a black-ops officer for the CIA but believes that now he's selling his services to the criminal element of New York, such as Elias. Donnelly wants to get Reese off the street and maybe get evidence of CIA wrongdoings on American soil, and he offers the resources of his FBI task force to help Carter track Reese down, but she decides not to tell Donnelly what she knows.
