Dead Ringers (S05E07)

Twins with a dark agenda are methodically eliminating those they deem troublesome. Their latest target is a Federal Witness, drawing the attention of an FBI agent who believes a former defendant has retaliated. Chris becomes increasingly intrigued by the investigation, straining her relationship with T.C. She suspects they are dealing with a serial killer, and the agent, impressed by her insights, enlists her help, much to T.C.'s dismay. When a witness to the twins’ violent behavior tries to reach Chris but ends up talking to T.C., he is swiftly silenced by the twins. Meanwhile, Bobby grows concerned that T.C.'s personal conflicts are clouding his judgment and informs the FBI about the twins, who may be working together. One twin attempts to ensnare Chris, but she manages to escape.
