Soft Target - S2-E6
Character mistake: On the roof, Don and the other agents have their weapons drawn on James Grace, who is holding Houseman hostage with the fake bomb. Once Grace is taken away, the threat is gone. But Don still has his gun pointed at Houseman, with his finger on the trigger. Houseman, while Don might think is a jerk, was innocent of any crime. There's no reason an agent like Don would have his gun pointed at him.
Suggested correction: Honestly, I just rewatched the scene in question, and I really wouldn't consider that a character mistake. It's not a super egregious mispronunciation to begin with (the difference between the sound of the words is quite minor), and based on the way she speaks and the fact she has a bit of an accent, it just seems like more of a personal affectation than a character mistake.
