In The Blacklist episode “The Travel Agency,” Agent Harold Cooper (Harry Lennix) asks Red Reddington (James Spader) for help with a case of “personal importance.” His friend, an off-duty cop, is missing and he’ll “do anything” to find him. Meanwhile Ressler (Diego Klattenhoff) tries to stop a reemerging murder-for-hire ring and Tom Keen (Ryan Eggold) meets Lena Mercer in a park.
Lena Mercer is portrayed by Ana Nogueira. She’s known for her roles on The Vampire Diaries (Penny Ares), The Battery’s Down (Molly Black), The Michael J. Fox Show (Kay Costa), and Blue Bloods (Nona Palmeira), among others. Nogueira got to work with the late Sam Shepard in the 2017 film Never Here (see link above). The Blacklist airs Wednesdays at 8pm on NBC.
