[Narrator] Previously on Supergirl:
The shrinking and collection of worlds is a common practice among our ancestors.
[Kelly] William and I discovered that Eve Tessmacher has been working for obsidian.
[Muffled grunting]
If you're gonna be a vigilante, maybe you should get better at hiding.
What do you mean, like wear a mask?
I don't know who this brainy is, but I know I don't trust him.
[Lena] Andrea knows nothing.
Seems on this earth, post-crisis, leviathan hasn't activated her yet.
[Lex] Gemma Cooper is warming to me.
And when she sees my newest present, she'll roll out the red carpet.
If that means helping them get a weapon or two, so be it.
You know what this weapon is, so you know what it needs.
Get it for me. And this time, do not fail.
Regarding your request to meet my colleagues?
- I'll send you a car tomorrow morning. - See you tomorrow.
I have made a terrible mistake.
Lex is working with leviathan,
and they are gonna use obsidian to do something terrible.
I wanna help stop them.
An elevator seems a little pedestrian for a goddess of technology.
Welcome to leviathan.
You know, I pride myself on seeing things,
connections where others see only coincidence,
pathways where others see only walls.
I anticipate everything, but I must admit, I did not expect you to live in a casino.
After you.
One small step for ma...
[Choking]
Lex Luthor, fabled man of tomorrow.
At least you have the decency to bow before the gods.
I told you to disable the shield.
As long as he knows where we live, it stays on, at all times.
- On whose orders? - Whose do you think?
The ship's defense mechanism, a proto-focused radiation shield.
This pin will protect you.
Wow, you really know how to make your guests feel welcome.
[Breathes deeply]
Well, now that the pleasantries are out of the way,
don't you think we should discuss our plan to take out Supergirl and her friends?
These rings bought you a ticket to board our ship.
So enjoy your photo op,
but leave the slaughter of Supergirl to us.
Thank you for letting me in, Kara.
It's been a year, and I still haven't come to terms with what I did.
I shot my brother and...
I mean, I know I thought I was protecting everyone, but it really started...
I don't wanna talk about the past.
All that matters now is the threat ahead of us and how we're going to stop it.
Understood.
[Door bursts open]
- [Alex] Get on the ground, now! - No. Alex, no.
Not about her. She's here to help us stop Lex and leviathan.
So Lex and leviathan are planning something using obsidian's virtual reality platform.
And my tech likely made that possible.
That must be why rama Khan went after the deo's kryptonite.
To keep Supergirl from interfering.
Well, the joke's on rama Khan and his big dumb gladiator outfit,
because I've already defeated him.
[J'onn] Don't be rash, Kara. He's tied to the earth.
Which means he can track your slightest movements.
If you use your powers even once, he will sense them and attack.
With all that kryptonite at his fingertips, he could kill you.
You guys will protect me.
Just like we protected the deo?
It's not checkmate.
Not yet.
I haven't made Kara an anti-kryptonite suit in this world, but I could.
We just need to get you safely to my lab.
Your lab is across the city, and Kara can't use her powers.
We could get her there, if we had the right distraction.
Or the right decoys.
No, no. No way. Absolutely not.
I can tell those pants will chafe.
[Supergirl-j'onn sighs then grunts]
[Supergirl-j'onn] I was right.
[Supergirl-m'gann] I quite like it.
This is just like the beginning of deathly hallows.
Moody and Hedwig died.
[Supergirl-m'gann] You lost comrades in battle? My condolences.
- No, they're... - It's the...
[Supergirl-j'onn] Dreamer and I will draw rama Khan out in Courtney park.
M'gann, Alex, you move across the rooftops to cover us.
While they're distracting leviathan, you and I will make our way to Luthor corp.
Come here.
I have to show you something.
Stay right there.
[Screaming]
[Kara] Oh, my god!
[Alex] J'onn made it for me.
She looks great.
[Supergirl-j'onn] Oh, it was a scream of delight.
Thank h'ronmeer.
Well, we should probably get going.
Stay safe out there.
[Gemma] I know that may not have been the most pleasant experience.
But rama Khan was just trying to protect the base.
Not only rama Khan, it seems.
And here I was thinking you were the top of the food chain.
I answer to another.
It took me a long time to gain her trust.
Which is why the unity festival must succeed.
I'm yours. Whatever you need.
Keep it.
You've earned it. That's why I brought you to the ship.
You're one of us now.
Today is the last day of the old era.
Tomorrow, the future begins.
Did you get the ship's location?
Indeed, but it has a nasty defense mechanism.
They gave me something to protect from it.
Give it to me.
Not yet.
We've come all this way. We've done all those terrible things
so I can sneak aboard the ship and upload the mortality code,
so that I can kill the immortals.
And we shall.
But first, rama Khan and his element-bending goons
need to eliminate Supergirl's friends one by one.
And when she has nothing left, they'll slay her too.
After that, you kill the gods.
You think I'm just gonna sit back while leviathan murders my friends?
Former friends. And yes, I think you will.
Because if you get on that ship any sooner, you'll die with them.
Leviathan is the enemy, Lex.
Not Supergirl, not j'onn j'onzz, not dreamer.
You're right. They're heroes.
They would happily sacrifice themselves to save the world.
Maybe they'll even thank us.
There's no place I can't find you.
[Supergirl-j'onn] That's where you're wrong.
[Supergirl-j'onn over radio] M'gann, you're off the hook. We've got rama Khan.
[Supergirl-m'gann] Copy that. We're on our way.
Wait.
There's someone else.
Another element-bender.
[Thunder crashing]
Got you.
There's more than one of us too.
[Alex] Kara, we got her.
[Thunder continues crashing]
Kara, come on. We've gotta go.
[Grunts]
Dreamer. Dreamer, what happened?
J'onn, no!
[Alex] Go, go, go.
[Sighs]
The suit won't be ready for at least another few hours,
but I'm doing everything in my power to speed it along.
- [Alex] Hey. - What happened?
It's not just rama Khan. There's three of them, each with a different element-bending power.
Where are the others?
J'onn was injured. M'gann and dreamer took him back to the tower.
I should've been there fighting alongside you. I'm sorry.
Kara, it's okay. We all still have our ears.
[Phone ringing]
- Kelly, hey. - [Kelly over phone] Oh, thank god I got you.
William texted me last night that he was going after Eve Tessmacher.
I haven't been able to reach him since.
William went after Eve alone?
- [Alex] No super-hearing. - Sorry.
Eve Tessmacher?
She's back?
Look, I'll get to you as soon as I can.
If this Eve is working with Lex, William has no idea the danger he's in. I...
Alex, I have to do something. I can't just sit here. I have to help him.
Okay. Listen to me. Stop.
I know how hard it is for you to sit on the sidelines.
But Kelly and I, we will handle this, okay?
We'll access Eve's files at obsidian north, and we'll see what she's up to.
And if she has gotten to William... hey.
We will find him.
You just need to stay safe until Lena finishes your suit.
[Sighs]
Okay. All right, fine. But please, be careful.
- You know me. - Yeah, exactly. That's what I'm worried about.
Come on.
The satellite uplink is nearly ready.
We should launch.
Gemma?
[Breathing heavily]
I was communicating with her.
- The news isn't good. - What is it?
Tezumak managed to injure one of the martians.
But Supergirl never even joined the fight, and the others got away.
I've gambled everything on this unity festival.
Then we have to make sure it goes off without a hitch.
[Andrea] Lex, Gemma.
It's time.
Shall we begin ending the world?
["Olive garden daydream #47" playing]
J“ girl, let's get stoned on account of the little one j“
al's dive bar?
This is where you summon me at a time like this?
It's the place where you first gave me this mission.
Defeat leviathan...
No matter the cost.
Today, I will feel the full extent of that cost.
Querl, I know things spun out of control last time you disobeyed Lex,
but you don't have to do this.
You don't have to let your friends die.
I don't plan to.
I don't plan on using Lex's mortality code on the gods either.
But how will you defeat them?
By using this.
Rather than kill the gods,
I shall reclaim the actions of our ancestors...
For good instead of evil.
I'll shrink them.
I'll bottle them here in stasis
where they can harm neither this planet nor my friends.
But if you enter the ship without Lex's anti-radiation pin, you'll...
I pushed away everyone I loved because you told me I must.
You were right.
This planet, my friends...
It's worth it.
I called you here simply because...
I don't wanna die alone.
Citizens of the world, today we stand on the precipice of history.
Ours is a world of pain and suffering.
Of conflict, of chaos.
But when you enter obsidian's world, the problems of the real one melt away.
In virtual reality, there's nothing to want.
No reason to harm one another.
It's a place where we can be our best and truest selves.
This world can be our real world.
And it all starts today with the obsidian worldwide unity festival.
Oh, nice. Did someone call for tech support?
I just said a mask, but...
Wow.
Bummer we have to get straight to business.
Yeah, I guess you inspired me.
I could have never gotten past security.
- My girlfriend's a badass. - Breaking into a tech corp, that's easy.
What I battled earlier today?
These are gods.
I mean, I finally got this baby working, but compared to what those guys are packing,
I might as well have brought a slingshot.
I've never felt so human.
[Computer chimes]
We... we... we got something.
Eve's ip address.
- Okay. - Wait, it's encrypted.
Better call Lena.
This program should be able to crack Eve's Cypher in minutes.
Talk about history repeating itself.
Tracking Lex down through Eve, it's...
It's just like kaznia.
Please, Kara. I'm sorry, okay? I truly believed what I was doing was helping people.
I told you, I don't wanna talk about the past.
Oh, come on. You can scream at me. I know I deserve it.
Working with non nocere was a mistake, that working with Lex...
This isn't about Lex.
This is about j'onn and Alex,
and all the other people that could have been killed today because they're on my team.
- Don't you understand that? - No, I do. Of course I do.
No, you don't.
You've never understood what it means to share a secret identity with someone,
how much danger that puts them in.
You never understood that I kept my identity from you because I wanted to protect you!
And I know, I know that I hurt you by waiting so long to tell my truth,
but what about all the ways you hurt me?
You pretended to be my friend for weeks just so you could manipulate me.
You stole from me. You convinced me to steal for you.
And then... then, you even...
You used kryptonite on me.
I made one mistake, one mistake
that was only ever meant to protect you, and in return,
all you did was hurt me in every way imaginable.
- I'm sorry. - I know you are.
But if you came to me looking for absolution,
I can't give it to you.
[Computer chimes]
It's Eve's location.
I'm going.
- No, Kara, your suit isn't ready yet. - I don't care.
Protecting people is what I do. You should know that by now.
Then I'm going with you.
[Eve] Now that you're up, you better start talking.
- Why were you following me? - I'm pursuing a story on Lex Luthor.
I know he's up to something criminal.
I don't know your involvement, but I believe you've been working for him.
You have no idea what you've gotten yourself into.
You should have stayed out of it. Now I have no choice.
I'm a journalist, okay? I can read people.
You're a good person who looks trapped.
It's clear you're not a killer.
What does he have on you?
Did he threaten someone you care about or...?
My mother.
[Gasps]
I am so sorry, but you don't have to fight this alone.
I can help you and your mother.
We can bring the truth to light.
If the truth comes to light, my mother is dead.
Eve, please.
I really am so sorry.
[Groans]
[Supergirl] It's okay. I've got you.
Okay. The bullet went through and through, but we need to get you to a hospital.
No, no, no. He's losing too much blood. There's no time.
Okay. I can cauterize it, but it's gonna hurt.
- [William] Do it. - [Supergirl] All right.
Don't do it!
Too late. Too late. It's done.
Are you okay?
Yes. I just... it just hurt.
All right, what happened here?
I was following a lead.
Gotjumped.
Uh, reporting 101, if you get kidnapped, you must be on the right track.
Something Kara Danvers likes to say.
She was working the case with me. I need to make sure she was all right.
[Lena] Kara's fine.
I spoke to her. She's in a safe place.
[Thunder crashing]
[Shrieks then grunts]
Get William and Eve out. I'll deal with this.
- Are you mad? They've got kryptonite. - Better get that suit here fast.
It's already on its way, and I'll call for backup.
[M'gann over comms] Did someone call for backup?
Now it's a fair fight.
Couldn't let you have all the fun.
I can't believe you left to fight earth, wind and fire without us.
They're... they're gone.
The explosion killed them.
We have to get out of here, now.
- [Metal squeaking] - [Grunts]
[Whooshing]
Let's replenish ourselves and finish this once and for all.
That's when their bodies started to reform like out of a horror movie.
- Yeah, but that means... - They're indestructible.
Immortal.
This isn't about defeating them anymore.
They want us to fight until we drop,
so they can distract us from whatever Lex is planning.
Eve will know what that is.
I'm gonna go find out.
Eve. Eve, can you hear me?
- Is the reporter okay? - Yes.
He told us everything.
Please understand.
I was just trying to protect my mom.
But Lex is gonna kill her.
I know you must feel like there's no way out,
but it is when things feel their most hopeless that we have to dig deep to do what's right.
Othennise the bad guys win.
Help us, Eve.
Help us fight.
And I promise I will do everything to keep you and your mom safe.
Gemma Cooper is not who she says she is.
Her real name is gamemnae.
She's a member of leviathan just like rama Khan.
Tonight, they're planning to attack the unity festival.
Once all four billion subscribers are inside...
Gemma will kill them all.
I recommend the chocos.
How's j'onn?
Recovering.
You can't fool a psychic. I saw you hesitate during the fight.
You dreamed something.
And it terrified you.
What did you see?
- Brainy. - You two were a couple, right?
You know j'onn. For a deeply serious man, he's got a big mouth.
I know.
It was more than a relationship.
We were partners.
We protected each other.
It turns out the one thing I couldn't protect him from was himself.
I told him to take off those inhibitors.
Maybe these dreams are because of my guilt.
There may be more to what he's going through than you know.
When j'onn discovered that I was a white martian,
he thought the worst of me.
Until he finally saw my soul.
- I'm not a telepath. - No, you're a dreamer.
And like it or not, you're dreaming now. You have to engage with it.
It could have meaning far deeper than you realize.
I'm sorry, m'gann. I need to be keeping brainy out of my mind, not letting him in.
There's nearly a billion people logged into the unity festival already.
- Can we shut down the system? - Or destroy it somehow?
No, the Luthor powercore has an indestructible fail-safe.
So you're saying we need to convince billions of people
to log out of a virtual reality paradise of their own free will?
Hope you've got one of those classic hope speeches handy.
I mean, I've done it before, but never on this level.
[In unison] If anyone can do it, it's you.
Jinx.
All right. So, what do we do about leviathan?
[J'onn] We'll fight till our last breath.
J'onn, are you sure?
With you by my side, a hundred percent.
We need to do something to draw leviathan out.
I'll send them a message.
- What are you gonna say? - Something to get their attention.
[Gasps]
That arrogant martian thinks he can speak to me like that?
I'm a god!
Once we're done with this world, I'll turn to Mars next.
Now's your chance.
[Chokes]
[Groans]
Place your hand on the central terminal. You'll be able to upload the shrink code.
[Grunting]
Now you can't move your hand, or else you'll have to start over.
The upload will take 10 minutes.
- I don't know if I can last that long. - You can. I'll be with you the whole way.
[Grunts]
Kelly opened a backdoor into the festival. It should protect you from the kill switch.
Hopefully we can get everyone out before they hit it.
[Exhales sharply]
Let's do this.
This is amazing.
I've never seen anything like this.
No wonder so many people signed up.
- [Alex] There's still no sign of them. - [Dreamer] Guess they didn't take the bait.
Maybe you should have been meaner.
[Thunder rumbling]
I was just mean enough.
What, no Supergirl?
Let's see if we can't convince her to join us.
- [Lex] What's wrong? - Supergirl.
She's inside the unity festival.
We need to hit the kill switch.
Wipe out as many as possible before she has a chance to interfere.
There aren't enough people logged in yet. We need to hit 50 percent saturation.
What good is wiping out one quarter of the world
if the other three quarters rise up?
- We'll worry about that problem tomorrow. - This is about tomorrow.
You told me you answered to a higher power.
How will she feel when you give in on the mission before it's complete?
And if Supergirl is in the unity festival, then her physical body is vulnerable.
Rama Khan, tezumak and sela might be able to make it back in time.
- They need to take out Supergirl's friends. - Then what do you propose?
Send another assassin.
Someone who won't fail you.
We are nearing two billion simultaneous users.
Our dreams are finally a reality.
- Not just our dreams, Andrea, your father's. - Hm.
And leviathan's.
Leviathan?
How do you know that name?
Because I am leviathan.
What does that mean?
All I know is that leviathan rescued me that day in the cave.
It was I who rescued you.
And I've been looking out for you every day since.
But now I need your help.
Yes. Yes, of course. Anything.
There is great power in you.
I know you feel it.
The power of shadows.
I need you to use that power...
To kill Supergirl.
What?
- I... I can't. - Yes, you can.
And when you do, you'll have power beyond your wildest dreams.
And your company will be untouchable.
If you don't, your company will collapse.
You will lose everything.
Your father will be crushed.
And we both know he won't be able to survive the blow.
Everyone, listen to me.
There's something wrong with the program. You need to end the simulation now.
What are you talking about?
There's no one in here but my late husband.
It's so good to hear his voice.
Hey. Hey, kid.
Kid, can you hear me?
You need to disengage from the program.
Leave me alone. My mom is back.
I missed her.
It's not working.
There are too many people. They... They feel connected to their loved ones.
It's... it's spiritual. I have no idea how to break through to them.
I can give you a way to talk to everyone at once.
Try now.
[Supergirls in unison] I need you all to listen to me. You're in danger.
If you and I fan out to the side, we can draw their fire.
While you two attack from the middle, sound good?
Why not?
You ready?
- Nope. - Me neither.
Let's go.
[Groans]
Five more minutes.
Stay focused.
Andrea.
You've been activated.
If I don't kill Supergirl, they'll kill my father.
[Supergirls in unison] I know it can be addictive to live in a perfect place where nothing hurts.
But that's not reality.
Killing for them...
Going down this path, it won't keep him safe.
- How do you know? - Because I've been down it before.
We all get hurt,
but it's only by going through that pain that we're able to appreciate the good.
Pain is what helps us grow.
Without it, we'd never be able to...
To evolve, to overcome.
To forgive.
I've done terrible things to protect myself and the people I love,
but it has never kept me safe from pain.
It's just brought me a new kind of misery.
And I moved further and further away from the person I was,
until one day, I woke up and I was utterly alone.
Each of us came here because we're afraid.
I'm afraid of getting hurt, just like you.
And I do everything I can to escape pain, just like you.
But the cost of escape is too great.
[Groans]
[Lena] Years ago...
We made a promise to each other:
"You jump, ijump."
If you choose to go down this path...
I will be there.
If you wanna get to Supergirl,
you're gonna have to go through me.
We have to wake up now.
We need to end the simulation once and for all.
I believe in you.
[Groans]
I believe in you.
[Sobbing]
Hey. Come on, it's okay. It's okay.
It's okay.
End simulation.
[All] End simulation.
End simulation.
[Grunting]
All...
Done!
I had hoped you'd die screaming.
But I'll take what I can get.
[Rama Khan] What have you done?
Ibeatyou.
[Static crackling]
What's happening?
The coluan.
[Groaning]
I never thought I'd see the day.
Obsidian platinum, the most popular vr platform ever created...
And not a single person's using it.
Alex called. Leviathan has disappeared.
- You did what you said you would. - Almost.
I still have one promise left to keep.
You did it, querl. You did it.
You saved this world.
You saved your friends.
Will you stay with me?
Until the very end.
Nia?
Who do you think you are?
We had a plan.
Leviathan kills Supergirl. You kill leviathan.
And then together, we save this planet from the invulnerable aliens
who think they know what's best for mankind.
Why couldn't you just wait for Supergirl to die?
Underestimated me.
My friends...
I'd never let you kill them.
[Laughs]
No, brainiac-5. I underestimate nothing.
I knew you would decide to shrink the gods instead of kill them
due to your precious moral code.
I planned for that.
I just didn't think that you would kill yourself.
Well, Supergirl lives, but I have the bottle.
You gave me exactly what I needed.
I'm just gonna kill Supergirl myself.
It'll be fun.
And you...
Can die alone.
Just like you intended.
No, no, no. Brainy!
I should have listened to you.
It's brainy.
He stopped leviathan.
He saved us.
He needs my help.
- Mom. - I can't believe it.
- Oh, my god. It's actually you. - [Eve laughing]
[Eve's mother speaking indistinctly]
[Eve sighs]
In the last world, she betrayed us.
I may never know what was driving her...
But I do know what was driving you.
You didn't wanna tell me who you really were because you didn't want me to get hurt.
But I did get hurt.
And I did what I always do when people hurt me.
I built a wall, and I suffocated behind it.
Makes it very difficult to see things from other people's point of views.
But I see yours now.
And I am very sorry it took me so long.
You know, when you showed up at my door this morning, I...
I didn't wanna let you in.
And I kept waiting for you to let me down.
But at every turn, you came through.
Building that suit,
protecting my identity, supporting me.
I wasn't ready to accept your apology.
But maybe, maybe I am now.
Okay.
What now?
Well, there's still one bad guy left to catch.
Let's go take my brother down.
[Screaming]
Let's get to work, doc.
Right away, dear.
