In the Brooklyn Nine-Nine episode ‘Captain Latvia’, while the team prepares to face the MTA during their annual Christmas carol competition, Jake (Andy Samberg) helps his partner Charles (Joe Lo Truglio) look for the perfect Christmas present for his son Nikolai (Antonio Raul Corbo) — but the two end up in trouble with a Latvian criminal ring.
Charles’ girlfriend (and Nikolai’s mother), Genevieve Mirren-Carter, is portrayed by Mary Lynn Rajskub. She’s known for her roles on The Girlfriend Experience (Erin Roberts), 24: Live Another Day (Chloe O’Brian), Californication (Goldie), Veronica’s Closet (Chloe), and The Larry Sanders Show (Marylou Collins), among others.
