The Jennings have entered into a new type of warfare on The Americans Season 4 Episode 1.
Bio-weapons just became a part of the Cold War, and into that minefield our favorite Soviet spies stepped with all four feet.
Not only were they holding their first bio-weapon in their hands, it was in their home, where their daughter, Paige, knew about their activities.
Paige was suffering the after effects of learning about her parents' life, and the struggle promises to be very real for her all season.
She may not have to suffer alone, however, as her father appeared to be suffering as well.
