Chase says its the one thing Olivers been afraid to admit even to himself.

Oliver has no idea what that is, so its back underwater for him.

Flashback, the first of many: Oliver and his wig (which actually looks pretty good tonight!)

spare Gregors life only to jump straight to torture to get the man to confess what Kovars planning.

Anatoly warns that Gregor will never tell the truth when hes in pain.

Everything and everyone that you love will wither and die at your touch.

As last words go, thats awfully metal.

The Pakhans dead, long live the Pakhan!

Meanwhile, Oliver offers to see if he can get any information from Kovars housekeeper, Galina.

As Merlyn leaves, he bumps into Anatoly, who amusingly introduces himself simply as gangster.

Kovar congratulates Anatoly on his ascendancy, and Anatoly blamesKapiushon, or the hood, for Gregors death.

In other words, its time for a coup.

Anatoly rightly recognizes this is a big, terrible plan and urges Oliver to return to America.

In the present, Chase is keeping Oliver shirtless and chained (calm down, ladies and/or gentlemen!)

Oliver starts to vehemently threaten him, and Chase next says hell locate Olivers son.

Oliver may not know his location, but Chase brags that hell find it.

He leaves Oliver to think about his confession along with the person Chase will kill next.

Olivers starting to break down, but he still doesnt know what Chase wants him to confess.

NEXT:Do heroic ends justify torturous means?

Flashback: Anatoly and his crew arrive at the docks, while Oliver-in-hood keeps watch from the roof.

They locate the shipment, and its sarin gas, like something out of an episode of24.

Oliver says the hood helped him direct the darkness inside him, but Anatoly strongly disagrees.

Youre a fool to think a piece of cloth can separate man from monster.

The rest was me practicing.

On opening night, Oliver breaks in, killing all the guards on the way to the security room.

However, he spots a monitor showing Kovar interrogating Galina.

He races to her, but by the time he gets to her, shes dead.

Honestly, Id forgotten all about Evelyn.

Chase tells them that whichever ones still alive when he comes back gets to go free.

But if theyre both still alive, hell snap Evelyns neck himself.

She reaches for the knife, whimpering that she cant spend another day here.

Oliver almost sobs as he says he doesnt know, so Chase snaps Evelyns neck.

Oliver slumps to the ground, hissing that hes going to kill Chase.

NEXT:Oliver shocks himself with his dark confession

Now we cut quickly between the past and the present.

Confess, Oliver, he taunts.

Youre right; hell face justice, Oliver says before delivering Kovar a vicious, fatal blow.

In the present, Chase says Oliver doesnt kill because he has to.

Why do you do it?

Oliver whispers, Because I wanted to.

Then hes screaming it: I wanted to.

And I liked it.

Closed captioning indicates all present tense want and a past tense liked.

Chase isnt surprised, like having recognized like, apparently.

And with that, Evelyn jumps up, her death just another psychological turn of the screw.

She tells Chase she knew Oliver would break, and yeah, this twist got me good.

But poor Olivers flat on the floor,leveled by his confession or realization.

You promised to let me go, Oliver finally chokes out.

Chase says he will, but not before giving Oliver one final gift.

He points at Olivers Bratva tattoo, which he says probably reminds Oliver of a great victory.

Man, Josh Segarra gives good torture in this role.

Oh my God, this is maybe the shows best-ever use of past and present emotional parallels.

Oliver says it wasnt him, it was the hood.

One last flashback, to Merlyn congratulating a surgeon.

Yep, Kovars alive, but with a heavily bandaged face.

Ooooh, yessss, were going to get scarred, out-for-revenge Kovar in the present, arent we?

In the present, Oliver opens his eyes, alone and unchained.

I dont want to do this anymore.

Im shutting everything down.

Alas, well have to wait for next week to hear how the team responds.
