Supergirl

Previously on Supergirl...

If you're gonna save your world,

you have to work with Lex Luthor.

You must give up everyone that you hold dear.

Lex Luthor has launched 32 satellites to space.

Well, Lex and Leviathan are planning something

using Obsidian's virtually reality platform.

And my tech likely made that possible.

I am a god. You are nothing.

Do you understand?

I thought it was forbidden to use Myriad.

What I'm doing is finding people your brother disappeared.

Humanity can't be fixed.

They need to be controlled.

I want to help stop Lex and Leviathan.

Wow. This is amazing.

Rather than kill the gods,

I'll shrink them.

You gave me exactly what I needed.

I'm just gonna kill Supergirl myself.

It's Brainy. He needs my help.

Guys, I think I'm close to finding Brainy.

I've dropped a pin at my location.

I just hope I'm not too late.

- Brainy! - Nia.

Let me in.

Can't.

Yeah. Yes, you can.

- There's a panel. You can hit it. - Radiation.

I'm not gonna let you die.

Nia, you should hear this.

You have to work with Lex to destroy Leviathan.

Pushing you away, hurting you,

it was to protect you.

I love you.

No, you're not getting off the hook that easily.

You.

You didn't die?

You cannot kill technology,

but technology can kill you.

No, poison.

Alex.

I'll get Alex and Brainy out of here.

Where'd she go?

She's in the computer.

I've got them. You get back in there.

This is Martian nanites laced with potassium iodide.

It's gonna give your system a chance to repair itself

now that you're out of that room.

But it's not gonna be fun.

Gamemnae. I know how to stop her.

The Anti-Life Equation.

Leviathan were ancient aliens,

but Gamemnae's a technological being,

which is exactly what

the Anti-Life Equation was designed for.

All we need is a method of uploading it

into that center console,

which has to be the ship's command hub.

Like this?

Yes. Brilliant.

Supergirl.

Put this in the center console.

Everyone out now!

The Leviathan energy transfer has been initiated.

Are you all right?

I'd say I'm more than all right.

Now you're just showing off.

Not yet.

To think you said you weren't obsessed with the Kryptonians.

I told Lena that she had it right.

Aliens shouldn't be Earth's saviors.

A Luther should.

And now I will be.

Leviathan is gone.

Next, I'll get rid of the Kryptonian and all her friends,

and then the non-believers.

And once I fix this planet, I'll do what the Anti-Monitor failed to do.

Fix every other planet in the universe.

Well, that sounds like a good plan.

Please get back to the part about ridding this planet of the non-believers.

Leviathan intended to use Obsidian Platinum to kill people in VR.

Instead, I used Obsidian to upgrade people's brains in perpetuity.

A little thing I like to call, I Love Lexi.

- That's very alliterative, dear. - Thank you.

I knew that fixing this planet would require big moves

that not everyone would appreciate.

So, I took advantage of Lena's delivery system

to make sure that everyone in VR would always appreciate me,

no matter what I do.

And what about the people who were not in VR?

The ones unenlightened to the goodness that is my son?

The satellites I launched during the Obsidian World Tour

are armed with sonic weapons poised to obliterate the minds

of anyone who didn't get the I Love Lexi upgrade.

My satellites will be aligned

to beam the kill frequency in about five hours.

I assume I will be safe without being brainwashed to love you,

since I already do.

Course, Mother.

There's a special do-hickey with your name on it.

And your sister. You can't kill her either.

Why not? She killed me first.

If you hurt your sister in any way, I will turn on you.

And no amount of brainwashing will stop me.

You'll be all alone,

save for the sycophants you detest.

Think of how tragic your father's demise was.

Is that how you want to end up?

Save your sister.

I just got your signal.

Where are Eve and the others?

William took her and her mom to CatCo.

She agreed to go on the record,

tell him everything she knows about Lex.

Well, that's amazing, but does William really think

any article about Lex is gonna help right now?

How is that possible? Everybody thinks Lex is a hero.

I think it's worse than that.

The program I was developing was supposed

to expand the human mind, to do no harm.

It was on the Obsidian platform, but I think...

I think Lex reworked it.

Rewiring the human mind so that they adored Lex

when they were in the Unity Festival.

That's half the world's population.

What about the other half?

Eve told me about an experiment that Lex did on two mice.

One had gold eyes, and it adored him,

and the other...

Lex emitted some radiation from a Q-wave antenna onto it and it exploded.

I saw people's eyes flash gold when they were coming out of the VR.

That's why he launched those satellites during his world tour.

Dreamer. What did you dream?

I saw Lex as the Anti-Monitor.

He was destroying every planet in existence.

I have located Lex's satellites.

Twelve of them orbiting the Earth.

Each armed with Claymore cannons to fire on hard targets

should any one of them be tampered with.

It would appear the only way to shut them down

would be to shut them all down at the same time.

But only four of us can fly.

Synchronizing our movements, too, could prove impossible.

We could shut it down with the Dorkri Surth-Uh.

The what?

A Martian ritual which translates to "the binding".

And you could use this on the satellites?

It would require M'gann and I to join our minds, synchronize our thoughts.

We could create a web of psychic energy

that we could literally bind onto things and move them in unison.

We can do it.

Okay, but even if you stopped the satellites,

half the people out there are still gonna be brainwashed by Lex.

Lena, if you had the code Lex used,

could you reverse it using Myriad?

Myriad. Yes, but...

You'd trust me? Even after everything?

You want to help people.

Whatever else has happened, I know what's in your heart.

I will go to Obsidian, download the server database into a hard drive

and get it to you.

Well, that solves two problems.

Now, if we only knew how to make Lex mortal again.

We need his Kryptonite.

Not Kryptonite, Jarhanpurium.

Fragments of that planet must have made it to Earth.

It would be toxic to Lex, just like Kryptonite is to Supergirl.

But finding it would be like finding a needle in a haystack.

That's what my dream was about.

There was a green bottle, Kryptonite green.

I could invert the energy in the bottle,

run it through the machine I used to make Kryptonite.

Sprock. It could work.

The monument Supergirl was trapped in

on Shelley Island was also in my dream. The bottle must be there.

It's the same energy station Lex used last year on Earth-38.

- I'll go. - No, you're still too weak.

- I'll go. - And I'll go with you.

Brainy, you and Lena work on Myriad and her Kryptonite machine

for when we bring you back that bottle.

I'll get Myriad from the Fortress.

And there's got to be something there

we can use to weaponize the Jarhanpurium.

That way we can strip Lex of his powers

and make him mortal again.

Let's not forget,

Lex still wants to kill us all.

And he has Leviathan powers,

which means he can sense us, especially Supergirl.

He'll strike as soon as we try to make a move. We need another diversion.

I can buy you guys time by offering myself up.

We're not gonna let you do that, Supergirl. It's too risky.

If that's what it takes to save half the population and stop Lex,

I'm willing to take that risk.

Your sister is still MIA. You shouldn't be celebrating.

You should be out there looking for her.

Can't, Mother. If I calculated correctly,

we should be getting a call any moment.

Oh, see.
