She didn’t seem like someone who wanted retribution on her boss.

Then in the midseason finale, the twist: It was Dembe who poisoned Red and nearly killed him.

But… that didn’t make much sense either.

She’s been busy thinking about her past and how she ended up in the employ of Raymond Reddington.

But she can do something about it.

She can keep her word, herrealword.

DEMBE ZUMBA, NO.

And it’s worse than I could have imagined: Janet,nee Elise.

He leaves Janet, and the Post Office team is quickly on the scene.

Aram is skeptical, but he says he can reach the log of who has opened the safe.

He does get the databut it would take him days to figure out who that data actually points to.

So Dembe tells him he’s free to go and asks Aram to yo forgive him.

and even more frightened when Aram informs him that Samar and Ressler have just entered the building.

“We’re both guilty, Raymond,” Dembe tells him.

“I came here to see for myself: She’s not here.”

The Hunter knows who Dembe is and knows that his “slick-suited friend” can’t be far behind.

So he calls Aram demanding to know what they uncovered together.

So Aram tells him the name: Kathryn Nemec.

Red tells Liz, “Man’s greatest enemy is the dark forces pent up inside himself.

Every trespass I committedexpunged, cleansed as if it had never happened.

My confessor, who doth condemn me.”

It’s a little dramatic.

He tells Red, “Kate’s also very dangerous and absolutely relentless.

I guess she learned that from you.”

Indeed, she did, as we shall find out.

It sets off a bomb under the cabin.

You told me if he ever figured out you’re still alive, he’d come at you full-bore.

Well, lock and load, Katieyour war has come."

In the Roman Catholic Church, a requiem is a mass for the souls of the dead.

More broadly, it’s an act of remembrance for the dead.

In this case: Gloria Gaynor’s “I Will Survive.”

The little girl asks why her mother didn’t take her body when she left.

What happens in life writes a story in your flesh…

They’ll take this body and bury it deep."

She pulls over, shaking, and takes a pill from a prescription bottle.

“You will be what I am to her,” she tells Kathryn.

“With one exception: You will not love her.”

Three months later, Kathryn is taking care of baby Masha (also a very well-cast baby!

That is a profound gift I would do anything to protect your baby."

One night, as Kathryn is washing her face, she hears a man and woman arguing.

Katarina gets a cord around his neck, but he gets her by the hair.

So Kathryn slides a knife across the floor to Katarina… and Katarina slits his throat.

(Step 1 toward the Mr. Kaplan we know.)

Katarina says that Alexander can’t see this, and Kathryn tells her to go upstairs and shower.

“While you do what?”

“Clean the mess,” Kathryn tells her.

(Mr. Kaplan: Step 2.)

Before she was Red’s cleaner, Kathryn Nemec was Katarina’s, apparently.

Which I think is pretty generous, because Kathryn seems to be the only oneparticularlyconcerned with safety.

Because there isa lotto take in… Masha was abducted: “I started pulling away; we couldn’t continue the way we were.

He didn’t take it well.”

I was never going to end up with Raymond."

“Not on your own,” Kate tells her.

Between all these flashbacks, we get quick glimpses into what Mr. Kaplan is up to in the present.

Katarina comes stumbling in with Masha, both covered in soot and burn marks.

But Katarina tells her in Russian, “It wasn’t your fault.

He was a bad man.

I love you.”

She tells Kate to take Masha to Sam Milhoen in Nebraska.

I’m begging you, walk away…

I love you, Kate."

And so Kate does.

In a really lovely series of scenes, we find out that Kate moved to Amarillo with Annie.

That they fell in love.

That Kate did find herself a mortuary job because she doesn’t mind blood or guts.

Annie introduces herself as Annie Kaplan.

“I guess that makes you Mr. Kaplan,” he sneers.

And then he shoots them bothAnnie in the heart, and Kate in the head.

Kate was induced into a coma for three weeks while the minor damages to her brain healed.

Annie died before the ambulance even arrived.

In flashback, Kate is sitting at the front desk of Little Niko’s when Sam shows up.

And he wants to speak with Kate.

They just let a few shadows do the work.

That seems pretty damn clear!

it’s possible for you to never undo it."

But Red has an answer for everything: “Indeed, I need to control the danger to Elizabeth.

I have a vast criminal record predicated on that very principle.

It’s time to live up to my mission statement.”

Red’s flaw, of course, is that he forgot Mr. Kaplan’s mission statement.

From the ice rink in present-day, Mr. Kaplan accepts a call from Raymond.

Somewhere along the way, I stopped serving Liz’s needs to help enable yours."

You almost get her killed, and youbetrayedme."

Mr. Kaplan and I scream in unison.

“I kept my word to you.”

But in reality, I was helping you become a monster."

And she remembers what her father taught her: “Our stories are written in flesh.

And I am going to use that lesson to render you powerless.”

And Red, somehow, after all of this, still underestimates Mr. Kaplan.

She can’t get inside.

“You forget I was by your side the whole time,” Kaplan responds.

More importantly, as your cleaner, I know where the bodies are buried."

“And I’m going to use them and their stories to put you in the ground.”
