Arpanet (The Americans)

Duluth expresses exhilaration over the success of the mission, and a more reserved Philip reveals he was forced to kill the worker.

With Philip watching afar with a sniper rifle, Larrick tells Elizabeth that he has been ordered to Nicaragua, to set up a base and mine the harbor of Managua, but he will still be able to let them into the Contra training camp before he leaves.

Lucia is upset to learn this, because (as she tells Elizabeth) she planned to kill Larrick there in revenge for his atrocities in Nicaragua.

Elizabeth tells her that Larrick is more valuable as a cooperating asset, and expresses her doubts about Lucia's reliability to Philip.

In March 2014, FX confirmed that the seventh episode of the season would be titled "Arpanet", and that it would be written by Joshua Brand, and directed by Kevin Dowling.

Eric Goldman of IGN gave the episode a "great" 8.8 out of 10 and wrote in his verdict, "The Americans looking at the beginning of what will become the internet is an inherently interesting idea that it was fun to see the show explore.

Meanwhile, Nina's dangerous situation taking that polygraph test and Philip once again forced to kill to protect a mission was a reminder of just how perilous a life these people are living and how it can come crashing down at any time.

Hell, the episode gains tension just from watching Henry sit around in a house the neighbors have left empty, playing Intellivision.
