Season 1, Episode 4:

Cura Te Ipsum
The latest person of interest is Megan Tillman, an emergency room doctor by day and bar-hopper by night. At first, Reese and Finch think that Megan is being targeted by a serial sex offender named Benton, but they soon discover that Megan is the one stalking Benton, planning to kill him as revenge for when Benton drugged and raped Megan's sister, who later committed suicide.

Meanwhile, Detective Carter investigates the police lock-up robbery and visits one of the hostages, "Harold Burdett", an alias of Finch. He manages to throw Carter off the scent, but is convinced that it's only a matter of time before she catches up to them. In response, Reese pulls some strings to get Fusco transferred to the homicide task force, to the desk across from Carter, in order to keep an eye on her.
