51 free Hard Dexter trivia questions with answers — entertainment quiz, new questions added Aug 2026.
This is hard Dexter trivia, written for people who already know the Bay Harbor Butcher, the Trinity Killer and the Code of Harry. None of that is here. Instead the questions dig into the corners of the show: which lieutenant replaced LaGuerta after season one, what LaGuerta used to blackmail Tom Matthews, the name of Harrison's preschool, whose body was found beside Doakes, and how Brian Moser really killed Joe Driscoll. It also covers the wider franchise. There are questions on New Blood (Kurt Caldwell's real-life inspiration, the podcaster who came to Iron Lake, the finale's title), Original Sin (the year it is set, the changes it made to Harry's death) and Resurrection (Leon Prater, Harrison's job in New York, Blessing Kamara's past), plus production trivia: the theme composer, the showrunner changes, the CBS broadcast rating, the Peabody, the Emmy tally, and the Marvel comic. If you want a warm-up first, start with our main Dexter trivia quiz. Every answer was checked against the Wikipedia articles on the series and its characters, and each explanation adds one more detail worth knowing.
