Mr. Gregory Devry (No. 95) - S3-E11
Stupidity: Ressler and Navabi arrive at Janet MacNamara's location, and while the receptionist checks where she is, Ressler thinks that's the perfect opportunity to ask Navabi if she's OK, given the whole sex/firing thing. He says, "You didn't say anything on the way over," so there was a bit of a drive when they could have spoken about this privately! Instead, he gets a weird look from the receptionist who's privy to this entire discussion. Cheaper than filming a conversation in the car, presumably.
Answer: The man Red killed, Sam Scott, was Lizzie's adoptive father, not her biological one. However, at that time Lizzie (and thus the audience), was led to believe her real father abandoned her and her mother, so expect more secrets to be revealed how her real father actually died (or if he's even actually dead).
