Philip and Elizabeth are tearing their relationship apart just when they need each other the most.

We begin with Philip dropping a heaping helping of judgment on Elizabeth.

He was very upset about the couple murdered right in front of their 7-year-old kid.

I didnt do it in front of their kid.

He was in another room.

I didnt see him, Elizabeth shoots back.

What do you want me to say?

He doesnt want her to say anything.

Hes the one with more to say.

Im not doing the thing with Kimmy.

Elizabeth is pure venom.

Of course you arent.

You were never going to do it.

Then, a twist of the knife: You just wanted to f her.

You werent getting enough action here.

She tells Philip that she will take care of the Kimmy situation.

I warned her not to go to any Communist countries.

Im never going to see her again.

She pulls away, isolating herself upstairs.

Philip has just betrayed her, their homeland, and their entire partnership.

That would be a fatal mistake for most people.

At the FBI, Adherholt asks Stan to join him for a moment in counter-intelligence.

Every time I go someone dies, Stan says.

They are joined in the elevator ride by the traitorous mail robot.

Dont ever sayThe Americanswriters dont have a sense of humor.

Down in the safe room, Stan learns there has been a breakthrough.

Theyve ensnared an illegal, a Soviet spy living as an American citizen but this one is in Chicago.

They havent arrested him, but theyre watching.

And theyre unpacking his life from afar and gleaning information that could help them track and capture other spies.

And its all because the late Mr. Teacup had a pouch of diplomatic information that mentioned the sensors.

This operation is code-named Harvest.

They want to look peaceful, but really theyre just trying to screw us.

He tells Stan: Its gonna happen fast.

Theyre going to find the other spies.

(And we know, there are just a few episodes of the series left, so yeah.

You should be here, Aderholt tells Stan.

Its Thanksgiving, and Philip picks up Henry from his boarding school.

Henry has been detached from the family, but that may have allowed him some perspective on it.

He tries to help his dad with the failing travel business.

Hes offering to get a job.

Hes taking a lot of liberties that make Philip feel like a loser.

Elsewhere, Elizabeth is taking in a movie.

The 1955 heist dramaRififi.

But for now, with the summit looming, Elizabeth is following up on Paiges lead.

Back home, Henry has the first of two awkward encounters with his mother.

He catches her smoking and asks when she started.

Ive always smoked, she says.

I dont have to hide things anymore.

The next day, Henry and his dad play hooky.

Henrys parents are losing it.

Philip doesnt want to talk about it.

Its the first the entire family has been united in a long time.

Then a call comes in.

The Chicago operative sent an emergency signal.

Its her job to go help him get out although this could lead to her capture, too.

She would be expected to commit suicide.

Back home, Philip cant believe Elizabeth is packing a bag.

Its not going to look good.

Figure it out, she snaps.

One of us is in trouble in Chicago, Philip.

Im going there to help him.

Someone whos still doing his job.

At the Thanksgiving meal, even Aderholt and his wife are there.

He makes a remark about getting Renee, Stans enigmatic wife, a job in the bureau staff.

Meanwhile, Stan delivers a bizarrely political speech.

Im grateful for everything we have in this country.

Not everybody around the world wants us to live in peace and freedom.

But arent those the things the pilgrims came here for in the first place?

He goes on: There are people out there who dont like our way of life.

They are afraid of it.

That night, Philip is restless.

While rooting through a drawer, pulling out passports, he finds Elizabeths drawings.

Whatever he was planning to do, he just goes home instead.

Back in Chicago, Elizabeth is working with her accomplice on the plan.

It seems very likely they wont pull it off.

At the FBI, things are in full swing.

Henry gets a call from his mother.

Shes clearly thinking about the future or lack of one.

They have the second awkward mother-son conversation, wasting long-distance minutes on small talk.

Later, Henry tells his father about it and muses.

I dont know why shes so unhappy.

This was something Philip never considered.

Hes thinking of the drawings.

Hes thinking of his wife, not just his espionage partner.

He has isolated himself from that business, but she has sunk deeper.

He has left a dead-drop message for Oleg Burov.

We see Burov begin to translate it, but we don tknow what it says.

Then Philip makes a call to Elizabeth.

He knows shes in trouble.

He wants to know if she needs him.

She says she will handle it.

But its clear that shes scared.

Ill come, he says.

No one is asking you to do that.

Just sit tight, he says.

Im on my way.

For the first time in a long time, Philip and Elizabeth will be on the same side again.
