Identity Crisis (Person of Interest)  "Identity Crisis" is the eighteenth episode of the first season of the American television drama series "Person of Interest". It is the 18th overall episode of the series and is written by Amy Berg and directed by Charles Beeson. It aired on CBS in the United States and on CTV in Canada on March 29, 2012. Finch (Michael Emerson) and Reese (Jim Caviezel) take on the case of Jordan Hester, who appears to be living a double life with a very small online footprint. They soon discover two Hesters: Reese follows a male Hester (Rhys Coiro) while Finch follows a female Hester (Sarah Wynter), who he believes is a target. Reese finds the male Hester's apartment, and discovers they're making ecstasy while Finch explains to the female Hester what he does and suggests she move somewhere safer. As they do, Fusco meets with a prisoner (Christopher Denham) who was recently part of a similar case, and learns that the woman's name is actually Mary and the real Jordan Hester is the man. At her apartment, Mary drugs Finch with ecstasy, destroys his phone and leaves him to die in a fire; Fusco (Kevin Chapman) rescues Finch as Mary leaves to kill Hester. Reese destroys the ecstasy lab with Hester's help, then follows Mary to a restaurant, where she's arrested and her true identity, Tara Verlander, is revealed. Carter (Taraji P. Henson), who is keeping her distance from Reese and Finch, is approached by FBI agent Donnelly (Brennan Brown), who is also looking for Reese. Donnelly explains Reese's previous involvement in illegal, USA based CIA operations, which the FBI wish to expose, and believe he's now working as a mercenary for Elias. Meanwhile, Finch offers to answer any of Reese's questions about him while under the influence, but Reese chooses not to take advantage of his partner to satisfy his own curiosity.
