Kate Kaplan, The Blacklist

Mr. Kaplan (Susan Blommaert)

Mr. Kaplan worked for Raymond Reddington for many years, as a longtime confidant and fixer. She was often seen helping Red dispose of bodies and clean up crime scenes. Kate is a lesbian, as revealed in a conversation with Red in which she remembered she was sleeping with some coroner’s sister (Season 2, Episode 3).

She was shot in the head in Season 4, Episode 8, but survived. In the mid-season premiere of Season 4 (4×16 “Dembe Zuma”, 4×17 “Requiem”) Red found out that the person who was trying to destroy him was none other than Mr. Kaplan, and her backstory was revealed via flashbacks.

The younger version of Mr Kaplan (played by Joanna P. Adler) attended medical school but changed careers and got a masters in childhood development. She took a job as a nanny for Katarina Rostova, helped kill an abusive boyfriend and after Katarina went into hiding, met a woman named Annie Kaplan.

Another flashback showed a love-struck Kate building a life with Annie. One night as the ladies were about to enjoy a romantic dinner, a man Annie’s uncle had tracked down for missing a hearing came in waving a gun. He asked for Annie’s name and then snorted at Kate, “I guess that makes you Mr. Kaplan,” before shooting them both. Annie was killed and the bullet passed through Kate’s head, requiring her to have a metal plate put in but not causing permanent damage.
