The Americans Season 4 Episode 7: Есть EST?

This week's show seems to be a kind of housecleaning before the big blowup.  John Boy gets fired for a host of things that Stan the Man did;  Martha goes to Russia, Stan the Man is palling around with Phillip again, Elizabeth and Paige have a couple nasty spats about why it's Paige's responsibility to monitor Pastor Tim and his wife before they turn the whole Jennings family in, and Elizabeth goes to EST!
