Previously, on "Arrow" Twitch, and I will open your throat.

Slade Wilson.

Oliver Queen.

Let me show you how I'm going to die.

There might be a fighter inside of you after all.

[Both grunting] Sorry.

For what? For not telling you how I really feel.

Time to choose, Oliver, who lives and who dies.

No! No! [Gunshot] No! Whoever did this to her is going to suffer.

You cannot die until you have known Complete despair.

And you will.

I promise.

Amanda: A new player we've been tracking.

We've been calling him Deathstroke.

Slade's goal is to create [Indistinct] in the Mirakuru.

I can't stop him from doing anything.

Five years ago, I made you a promise.

I'm here to fulfill it.

[Thea sobbing] There is still one person who has to die before this can end.

Oliver.

Oliver, man, you ok? [Alarms and sirens in distance] The cure's not working.

We don't know that.

He still has a lot of Tibetan pit viper venom in his system.

[Alarm sounding] What's that? Proximity alarm.

I rigged the tower with sensors just in case Slade's goons came here to kill us.

Slade's goons are here to kill us.

Talk to me, Felicity.

They're inside, they're right underneath us.

[Roy groans] Where am I? They're inside, there's too many of them! [Shrieking] Felicity! Down the cable! [All screaming] Oh, my God! What the hell happened? Slade's army.

You were right about this place being compromised.

Lyla, your boss is going to bomb the city at dawn.

Yeah, Waller's never seen a problem she didn't think couldn't be solved with a drone strike.

Why do you think I'm here? You knew Waller was looking to level the city and you came here anyway? You're here.

You need to go back to A.

R.

G.

U.

S.

You need to stop Waller or buy us enough time to stop Slade.

Not without me.

Till death do us part, right? This time it might.

Guys? I need you to scrounge as many weapons as you can find, especially injection arrows.

We're going to fill them with the cure-- which clearly works-- and this ends tonight, without killing.

There's been enough death already.

No! [Sobbing] Malcolm: Thea.

It's called Kevlar.

[Scoffs] If you're going to kill me, just Get it over with.

Kill you? Why? Because you shot me? I'm glad you did.

You're sick.

Perhaps.

How else to explain the fact that not a year ago, your brother held a gun to my face as well.

Tommy? He lacked conviction.

The strength to pull the trigger, but not you, Thea.

You are made of iron.

You are truly my daughter, and I could not be more proud.

[Sirens and alarms in distance] Remember your training.

You be smart, you take clean shots, and you don't miss the-- Man on radio: Fall back to Meltzer Avenue.

We need SWAT at Union Plaza.

City hall's a crater.

[Gunshots] They're--they're everywhere! Fall back, fall back, I'm hit! Ok, listen, I know you're scared.

You wouldn't be human if you weren't.

But tonight, this city, our city It's counting on each and every one of you.

So you go out there and you be the heroes I know you all to be.

Go.

Where's your sister? I don't know.

Detective.

I've got one-P-P on the line.

Lieutenant Pike in the field, you're the ranking officer.

You should go.

I'll find Sara.

Listen, I don't want you stepping foot outside this precinct, you hear me? I won't.

I promise.

All right, sweetheart.

What do we got? My sister can't be a part of this.

I don't want her getting hurt.

Sara! What's going on? Laurel Well, it seems like I missed a lot.

Well, what do you remember? Leaving town and heading to Blüdhaven.

Was I out cold the whole time? Felicity.

You were out.

The whole time.

Slade has at least 50 or so of those human weapons.

We'll need a whole army if we plan on hitting 'em with the cure.

I know.

Which is why an army is what I've brought.

Gee, Sara, you could have called before you invited into our top secret lair.

What is she doing here? I asked her to come.

I'm Nyssa, daughter of Ra's al Ghul.

Heir to the demon.

Felicity Smoak.

MIT class of '09.

This is where you went? Nanda Parbat? The League of Assassins? These people are mercenaries, Sara.

Whatever they promised you, it comes at a price.

You don't have to worry about it, because I've already paid it.

You agreed to go back.

Look, I'm not going to let Slade Wilson hurt Laurel or my father.

And I'm willing to do whatever it takes to keep the ones that I love safe, and I hope you're ready to do the same.

Especially after what happened.

Ollie, I'm sorry about your mother.

I am willing to do whatever it takes, but that doesn't mean cold-blooded killing is the answer, Sara.

We have the cure now.

To fight the unthinkable, you have to be willing to do the unthinkable.

You may not want my help, Mr.

Queen, but there's little question you are in desperate need of it.

First we need to find Slade's base of operations.

Slade Wilson and Isabel Rochev are using your former office building as their base of operations.

How are you feeling? Ready to serve up some payback.

Then remember your training.

Remember everything that you've learned.

Are--are you for real? Someone--a friend-- once told me that if you survive a crucible, you grow the stronger for it.

This is to remind you of that.

What happened to Thea? Is sheOk? She's fine.

She was headed out of the city before this started.

We do this my way.

The league does not take prisoners.

It does tonight.

[Dialing] Thea, it's dangerous out there.

Better than here with my psycho-villain dad, who's happy I tried to kill him.

[Cell phone rings] Roy? Thea, it's-- it's me.

I just wanted to make sure you were all right.

I'm fine.

I'm at the train station.

Thea, listen to me.

You're not safe there.

Can you please meet me at my place? I'll be there.

Soon as I can.

Ok, be safe.

Who was that? Roy? You're my daughter.

There's not much I don't know about you.

Interesting how you run back to him after resolving to run away to escape all the lies and half-truths.

He's no different, Thea.

No different from your mother or Oliver.

If you don't believe me, then you should go to him.

I will.

And if you try to follow me, I'll shoot you again.

When you need me, I'll be there.

[Elevator dings] Elevator bank's clear.

[All grunting] Conference room's clear.

Deathstroke: You must have quite a bit of faith in this cure if you've come alone.

We didn't come alone.

Sara, don't! Kill me.

Don't kill me.

It doesn't matter.

I beat you.

I took away the one-- Your reticence to do what is necessary is why your city burns.

This isn't working.

I can't get close enough to Slade to hit him with the cure.

So what do we do? [Grunts] Another disappointment! Bring me another! Come on, Slade, what are you doing?! Advancing the cause of science.

Wait, no, no, wait, I know you blame me for Shado's death! I blame myself! He should! It's his fault we aren't together.

You said once that we were brothers.

And right now, I am begging you, brother to brother, just listen to me! Don't listen to him! All his words are lies.

I wouldn't be alive right now if it wasn't for you.

I would be alive if it wasn't for him.

Think about Shado! She--she cared for both of us.

She wouldn't want this.

She wants us off Lian Yu.

She'd want all of this to end! He's right! This needs to end.

You need to kill him.

Anatoly: Two hours now.

Prosti menya, moy drug.

I'm sorry, Oliver.

Do it.

Slade, no! Shado: Pull the trigger! Slade! Laurel! Laurel! Sweetheart, sweetheart! What--what happened?! Sara! She's gone, sweetie.

Oh, my God.

You ok? She's with that woman! The woman that took mom.

[Gunshots] Man: Please, no! Stay right here.

Stop right there! Don't take one more step.

One more step! Slade Wilson wants to see you.

No, no! Drone's locked on target.

Starling City.

Why does this Wilson guy have such a mad-on for the Queens? I don't know.

Good thing Thea and Oliver got out of town in time.

So they have to go after my family? What's she doing here? She's here to help.

Just trust me, please.

I guess today I'll have to work with anybody who can help get my daughter back.

What? One of these masked guys, they took Laurel.

I--I couldn't stop them.

Believe me, I--[Grunts] I tried.

Oh, we have a new, big problem.

Which, considering our other ones, is really saying something.

I hacked a satellite and tasked it for thermographic imaging-- all of Slade's men are gathering at the Giordano Tunnel.

I thought these guys were trying to destroy the city, not escape it.

A.

R.

G.

U.

S.

is going to level the city to stop them from getting out.

That's what Slade's planning on.

He knows Waller's tactics.

Fortunately, with Slade's men attempting to leave via the tunnel, all our targets will be grouped in a single place.

We need to take it.

Gather your men.

What about Laurel? Wilson took her for a reason.

I know what it is.

But the city comes first.

This is my daughter.

This is your sister! You can't just leave her like this! Look, I know you said you were trying another way, and I respect that.

But Slade Wilson? His men? They're monsters.

And monsters, they need to be destroyed.

You've killed before.

Tonight, I suggest you get back in the habit.

He's wrong.

He's right.

I've lost everything because I'm fighting Slade Wilson with one hand tied behind my back.

The man murdered my mother.

I have to kill him.

You told me you had a choice.

That years ago, you could have cured Slade but you chose to kill him instead.

This isn't happening because you're not willing to be a killer; it's happening because you were one.

You're right.

That's how this started.

It's how it has to end.

The only move that he has left for me is to kill him.

I can't cure him, I can't capture him, I can't even out-think him! Then don't.

Don't Just make him out-think you.

Residents are being urged to stay in their homes amidst unconfirmed rumors that mayor Blood is among the casualties as masked men terrorize the city I'm sorry.

I'm sorry for everything.

I No, it's ok.

I know--I know that I haven't exactly been myself for the past few months.

I was injected with With some drug.

I know.

Sin told me.

But are you ok now? Yeah, I'm fine.

I woke up here.

I lost a lot of time, but And what about the Arrow? He said he was going to take care of you? I don't know anything about the Arrow.

I'm done with all of that, but I You're the only person that I've ever cared about.

Are you okay? Did something happen to you? It doesn't matter.

Look, let's just-- let's just get out of here.

Let's start over.

We can be whoever we want to without anyone getting in our way.

I'm never losing you again.

[Cell phone beeps] Yeah, there's just-- there's just one thing I need to take care of before we go, ok? So just stay here and get some stuff packed and I'll be right back.

No, Roy, it's dangerous.

I know.

But I have to do this.

I wouldn't feel right if I left without trying.

Do you trust me? Yes.

Then when I get back, we're getting out of here forever.

I love you.

[Door opens and closes] Felicity: Oliver.

What are we doing here? The whole city's falling apart.

I know.

[Exhales] You need to stay here.

What?! Why? You can't just ask me to-- I'm not asking.

I will come and get you when this is all over.

No! Felicity No! Not unless you tell me why.

Because I need you to be safe.

Well, I don't want to be safe.

I want to be with you.

And the others, unsafe! I can't let that happen.

Oliver.

You're not making any sense.

Slade took Laurel because he wants to kill the woman I love.

I know, so? So he took the wrong woman.

Oh I love you.

Do you understand? Yes.

Johnny.

Yeah? Never mind.

Hey, Lyla.

I love you.

You know that, right? I do, actually.

But it's good to hear it.

[Beep] Amanda: Time to impact? Drone is 52 minutes out from target.

Get me sergeant Gomez at the Giordano Tunnel.

Easy company's not responding, ma'am.

I need a visual.

They're in a tunnel, ma'am, I can't get a picture.

What the hell is going on in that tunnel? Sergeant Gomez, come in! Sergeant Gomez! No kill shots.

Let the cure do its work.

Ready? Ready?! Ready, fire! Agent Michaels, this area's restricted to all unauthorized-- What the hell is this? Early parole? Waller's looking to bomb Starling City.

We need your help to stop her.

As much as I'd love to show the Wall what we think of her, there's just that little matter of tick, tick, boom! Ok? We've got all that miniature bombs in our spines.

You have to trust me.

And Lawton, no dropping bodies.

Yeah, sure, take the fun out of it.

Nyssa! [All grunting] Get off the ship! Sara: Not without you! Give it to me! Give me the Mirakuru! No! Ollie! Sara! Prep the drone to fire.

Weapons hot was set for oh-six hundred.

Prep the drone to fire! [Gunshots] Down, now! Everybody get down, down, down! Waller, call that drone off! This is treason, agent Michaels.

Treason that risks hundreds of thousands of lives.

Have you thought about that? Have you thought about how you're going to explain that to your son? Or is it your daughter? Did doctors specify, or did you want to keep it a surprise? Congratulations, Mr.

Diggle, you're going to be a father.

Go! Slade: You've been busy, kid.

It's over, Slade! Your army is broken.

And I pity them.

But once again, you miss the point.

I have the one you love.

You're going to meet me where I say.

Otherwise, I'm going to kill her.

No, you do what you have to.

I'm done playing your games! You're done when I say you're done! I was surprised.

I thought you had a thing for stronger women, but now that I've met her I can see the appeal.

She is quite lovely Your Felicity.

Slade: Twitch, and I will open your throat.

My first words to you.

Do you remember? I do.

I remember the exact moment.

My blade against your neck.

Just like my blade is against the neck of your beloved.

If only I'd killed you then, everything would be different.

Drop the bow, kid.

Do it.

[Felicity gasping] Slade: Yes.

Countless nights dreaming of taking from you all that you took from me.

By killing the woman I love? Yes.

Like you love Shado.

Yes.

You see her.

Don't you? Well, what does she look like in your madness, Slade? What does she say to you? I remember her being beautiful.

Young.

Kind.

She would be horrified by what you've done in her name.

What I have done? What I have done is what you lack the courage to do! To fight for her! So When her body lies at your feet, her blood wet against your skin, then you will know how I feel! I already know how you feel.

I know what it's like to hate.

To want revenge.

And now I know how it feels to see my enemy so distracted, he doesn't see the real danger is right in front of him.

[Groaning] Do you understand? Yes.

Kill her! Get them out of here! Poor Sara.

How many times you going to watch her die? [Grunting] You can't kill me.

The Mirakuru isn't what made me hate you! [Groaning] The end is near.

But maybe I'll be merciful enough to let you live and see your city burn! [Both grunting] We both know there's only one way that this can end.

To beat me, kid, you're going to have to kill me.

But in the moment of my death, you'll prove one thing-- that you are a murderer.

[Both grunting] What are you going to do, kid? Stick me with the cure? It doesn't matter.

I'll keep my promise! I'll take away everything and everyone you love! Sara was only the first! She was only the first! Your sister, Laurel, your mother! [Both grunting] You can kill me, or not.

Either way, I win.

[Beeping] Oliver: Amanda, it's over.

Slade's down, his army's been taken out.

Call back the drones.

Amanda, it's over! So what now, kid? It's time.

Why--why are they making you do this? Why are you making her do this, huh? Why? Dad, she's not making me do anything.

I chose this.

What am I going to tell your mother? Tell her that for the first time in my life, I'm deciding my own fate.

She'll understand that.

Yeah.

I love you, sweetheart.

I love you, too, Dad.

I know the power of a father's love, and I would die before I let anything happen to your daughter.

Well, here's hoping.

So, where you're going, will you be able to email or call? I'll see you again.

I know.

If there's anything that I've learned this year, it's that you always find your way home.

And we'll always be here waiting.

I love you.

I love you.

Oliver needs you.

And, hey I think that this would look good on you.

It fits.

Bye, Dad.

Bye, sweetheart.

About that jacket Don't get any ideas.

[Laughs] I could really use a meeting.

Yeah, probably a good idea for the both of us.

Listen, I got to pick up a little pepto on the way, though, 'cause I'm feeling kind of weird.

Dad, she'll be ok.

Yeah, I know she'll be ok, but ok what is what bothers me.

[Groaning] Dad? Dad! Oh, my God.

Dad! Dad! Oh, my God! I can't get my breath! I can't [Gasping] Dad, stay with me! Daddy, daddy, stay with me! Hello?! I need an ambulance.

My father's with SCPD.

Yes, now! Daddy, stay with me! Thea.

Thea! Thea: RoyI'm sorry.

I made a mistake.

I thought I could still be with you.

I thought I could still be Thea Queen.

But Thea Queen was trusting.

And I don't trust you.

Or anyone.

Not anymore.

Thea Queen was also weak.

And no matter what it takes, I will be strong.

Don't try to find me.

You won't.

Even I don't know where I'm going.

I only know one thing-- I am never coming back.

[Gasping] Where am I? As far away from the world as I could get you.

Where you can't hurt anyone ever again.

That's your weakness, kid.

You don't have the guts to kill me.

No.

I have the strength to let you live.

Oh, you're a killer.

I know, I created you.

You've killed plenty.

Yes, I have.

You helped turn me into a killer when I needed to be one.

And I'm alive today because of you.

I made it home because of you.

And I got to see my family again.

But over the past year, I've needed to be more And I faltered.

But then I stopped you.

Without killing.

You helped me become a hero, Slade.

Thank you.

You think I won't get out of here? You think I won't kill those you care for? No, I don't.

Because you're in purgatory.

I keep my promises, kid.

I keep my promises! I keep my promises.

Last time I didn't notice; It's actually kind of beautiful here.

Don't get me wrong, I'm counting down the seconds until we shove off minefield island.

So you think that'll be enough to hold him, A.

R.

G.

U.

S.

' super Max? Him, and anyone else we send here.

This battle may be over, but there will be others.

Starting with getting my family's company back.

That's not going to be easy, since you're poor now.

You're going to have to get a job.

If Slade doesn't scare you, that's got to.

Do you know anyone hiring ex-billionaires with superior archery skills? Hey, why don't I, uh, give you two a second? Well, you did it.

I had help.

Yeah.

That's really smart.

How you out-foxed him.

Talk about unthinkable.

You and me, I mean.

When you told me you loved me, you had me fooled.

For a second, I Maybe you might have meant it.

What you said.

You really sold it.

We both did.

Let's go home.

Dig, what was the news about you and Lyla? It can wait.

I'm flying.

Be my guest.

I got one more question! Wouldn't be you if you didn't.

If you spent five years on this island, when did you learn how to fly a plane? [Gasping] Gun ngo lei.

My name is Amanda Waller, Mr.

Queen.

We have a lot to discuss.

Welcome to Hong Kong.
