Guilt plays a large role in this week’s episode of The Americans. “Martial Eagle” is a very powerful episode, leaving you glued to the screen more than once during the 70 minutes it’s on. Things don’t go as planned for Philip (Matthew Rhys) and Elizabeth (Keri Russell) at Martial Eagle, the training camp for Nicaraguans, which has a profound effect on both of them. FBI Agent Stan Beeman (Noah Emmerich) addresses his guilt during “Martial Eagle” as well, on top of dealing with a heartbreaking turn of events with his wife Sandra (Susan Misner). Guilt can do strange things to people, as we see in this ninth installment of The Americans.
