“Medusa”
Setting an X-Files episode in the subway system is a solid local. I read some criticism that the subway they showed was way too clean and pristine, but I have never been in a subway before so that is something that I would not have thought about without the comment.
Scully and Doggett were here to investigate a death of a man on the train whose body had been eaten away. They received plenty of push back from the people in charge of the subway, who were not prepared to shut down the subway and cause chaos among the people who used it.
Doggett went down into the subway tunnels as Scully stayed behind to man the center. Though not mentioned, I wondered if this was because she was pregnant and she did not want to potentially expose herself to an unknown contagion. That does not feel like Scully, but it could be the underlying tone of the situation.
Transit police Lieutenant Bianco had lots of negative things to say about Scully, and it felt as if he did not want to be taking orders from a woman. I do not know if he was meant to be shown as misogynistic or just a jerk who did not want to be there, but he was back talking her and running her down to Doggett through much of the episode.
I am not sure how I felt about the end of the episode. It seemed that the mute boy came out of nowhere and the end of the medusa, the cause of the contagion, was killed so easily. It did feel too quick and did not develop it enough.
