Plot summary
Reese and Finch are given the number of Jordan Hester, whose identity matches both a male and a female individual. Finch believes the female Hester to be in danger, but learns that she is an identity thief named Mary, while the real Hester is the man. Mary drugs Finch and leaves him to die in a fire, but Fusco rescues him. Mary goes to kill Hester, but Reese gets her arrested, exposing her real identity as con artist Tara Verlander. Carter, keeping her distance from Reese and Finch, is approached by FBI agent Donnelly, who is also pursuing Reese. Donnelly explains that Reese was illegally involved in CIA operations on U.S. soil, and the FBI believe him to be working for Elias.
