Santa Claus - S1-E12
Visible crew/equipment: When Mark Harris shows Matlock into his office, the actors' T-marks can be seen on the floor under the chair.
Factual error: This takes place in Atlanta, but in the scene where Tyler pulls up to Matlock and The Professor on the bench, there are California-style palm trees visible in the background. (00:18:35)
Answer: If it was ever found out that she was at Terry's house before he was killed, there's a possibility that a lot of people would have begun to suspect her of murdering Terry. By claiming that she wasn't, she was hoping that people wouldn't accuse her of the murder.
