Last week, FX brought back their hit drama series The Americans with the Season 2 premiere "Comrades". As fans get ready for this week's episode, "Cardinal", airing Wednesday, March 5 at 10 PM ET, executive producer Joel Fields, who also wrote last week's episode, answers fan questions from Twitter in a new behind-the-scenes featurette. The writer-producer addresses how they create flashback sequences for the show, while teasing that fans can expect more back story for Nina (Annet Mahendru), Phillip (Matthew Rhys) and Stan (Noah Emmerich) in future Season 2 episodes.
