Karim Washington

Karim Washington is a private investigator working a missing-persons case, hired to track down a runaway teenager. Sharp, methodical, and a little weary, he moves through the small town asking careful questions, following threads that keep leading him closer to the strange, secretive group orbiting Prairie Johnson.

Kingsley Ben-Adir plays him as the show's skeptical anchor, a grounded professional whose procedural instincts butt up against increasingly inexplicable circumstances. That tension between hard-nosed detective work and creeping wonder gives The OA's more outlandish turns a credible witness, someone whose doubt makes the mystery feel earned rather than indulged.
