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.
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.
Ah, the maid of might. What a surprise.
We know you've placed satellites around the world,
and when they sync up, they'll send out a signal
killing everyone you haven't brainwashed.
What do you want? A gold star?
I want you to disable the satellites.
You do that, I'll give you what you've always wanted.
What's that? And don't say hair, that's low-hanging fruit.
Me.
Well, that is tempting.
I assume there's no strings attached,
no trap, no attempt to outwit me.
Or has the razzle dazzle of my immortality
made you forget that I'm the smartest man alive?
Do you really think I'd fall for something so prosaic?
I'm wearing a Truth Seeker,
and I think your obsession with me
outweighs your desire to kill half the world.
I surrender.
Name the place, and bring a way to disable satellites.
Any place?
As long as no civilians get hurt.
The Fortress. One hour. I hear it's beautiful this time of year.
I'll send you the coordinates.
You aren't actually considering going to the Fortress, are you?
Of course, it's a trap.
Ah, no. I'm taking advantage of an opportunity.
Supergirl hasn't seen new, improved me in action yet.
I will destroy her.
And while you're doing that, her friends will be busy undoing all your hard work.
With Supergirl out of the way, her friends will be easy targets.
And even if they're successful, at stopping my satellites,
I'm a god, Mother.
I'll have plenty of time to fix what they mess up.
Oh, uh...
and silver lining...
if Supergirl's friends go behind my back and take down my satellites,
you don't have to worry about Lena.
You see...
it is time to celebrate.
Andrea...
What happened?
My father, he...
he blames me for everything.
What do you mean?
Just...
Leviathan...
hijacking our technology, destroying our company.
He said I destroyed his legacy.
I'm so sorry.
I sacrificed everything for him.
I sold my soul...
to make Obsidian North a success.
Once the market opens tomorrow I'll...
I'll be bankrupt.
Not just Obsidian, but CatCo, too.
Your father...
is a selfish narcissist.
You are a brilliant woman...
who built this place from sheer force of will.
The mistake was doing it for him.
Well, I haven't seen you this tense since...
well, since the last time the fate of the world
rested on our shoulders.
Redirecting those satellites
isn't as simple as melding minds.
To engage on that level requires
complete openness.
M'gann will see everything about me.
Memories of my daughter, my wife...
every violent thought I've ever had...
about white Martians...
She will know things about me
that I would never choose to share.
What if...
subconsciously,
my apprehensions derail us?
We might not be able to take those satellites offline,
I could...
kill both of us.
J'onn, you have been through so much in your life.
War,
loss,
love.
You've had to face some hard truths.
But so has M'gann.
You know, I...
I know it's easier said than done,
but at the end of the day, all you can really do is trust.
And who knows,
engaging like this,
being this open with M'gann,
it could lead to something really beautiful.
I meant what I said before.
I truly am so sorry for everything.
You hurt me, Brainy.
You abandoned us.
I know it was to save the world but...
What's the point of saving anything
if it means you have to hurt the people who love you?
Yeah. You're right.
Take this. It's a loaner...
while I'm recovering.
And the first step in trying to...
make up for everything I've done.
Who knows,
it might be of service.
With Obsidian North set to lose billions
with the misfire of their VR platform,
Bernardo Rojas made a stunning public rebuke of his daughter
in an interview earlier.
There's a section of the armory
that's just artifacts from the Andromeda Galaxy.
-The Jarhanpurium weaponry should be in there. -Okay.
I may be able to reinforce the anti-Luthor protocol.
It won't kill Lex now that he's immortal,
-but it might slow him down... -Lena...
Kara,
he's gonna try and kill you.
All right? I won't let you turn this
into a suicide mission. I can't.
We've got no other choice.
It's okay. I've come to terms with it.
As long as you guys stop the satellites,
and help everyone with the Myriad...
It'll be worth it.
When Lex comes,
you're gonna wanna take the higher path, but you know him.
He plays dirty. Mean. -Hm-mm.
Maximizing the pain wherever he can.
Well, I was stuck in the Phantom Zone
replaying the destruction of my planet
for nearly a decade.
Bring it on.
We should probably...
Kara.
I know it wasn't easy to trust me again.
Especially with Myriad...
You're the only person in the galaxy
I know would do right by it.
Come on.
I'm sorry, Father.
I got the weapon.
I'll go get Myriad.
Oh, um, I'm gonna borrow this portal watch.
I think it could come in handy.
Yeah, as long as you return it.
I always return the things that I borrow.
Oh, yeah? Tell that to every graphic tee
I owned from junior high on.
You know, it is...
it's just really nice to see you working with Lena again.
Yeah.
Yeah, we've got a ways to go but...
It is nice.
I love you.
Always.
We have to go.
Right.
I will see you later.
With this. Maybe.
Good luck, Kara.
You, too.
I am Kara Zor-El.
I'm entrusting a record of all of my knowledge
and experiences into the crystals you see before you...
in the hope that they will bring guidance to others,
whenever they need it,
now that I'm...
now that I'm gone.
This is my legacy download...
Audio-visual, volume one.
We have to make sure that all the satellites
are in exact alignment to start the binding.
-What's wrong?
You realize,
after this,
win or lose,
everything will be different between us.
Well, then we better make this count.
How's it coming?
Kelly was able to access Lex's code at Obsidian.
Thus far, it's been easy enough to reverse engineer,
but the sequencing, the control flow...
the way Lex was able to override free will
with a few keystrokes...
is quite terrifying.
The code was my design...
Are J'onn and M'gann in position?
Affirmative.
And we're ready to trigger Myriad
as soon as they take down all the satellites.
Hopefully, Supergirl will keep Lex busy long enough
so we can stop him.
Lena, I...
I need you to know that
I had no idea that this was Lex's plan.
I thought that if... if I was...
close to him, I would be able to know...
how and when to stop him, but I...
I didn't.
I was so worried that...
by working with Lex I was becoming the villain,
that... that I lost track of...
of what he was up to.
I thought...
that by doing this I would help save the world,
but...
look what it's done...
Brainy,
you were willing to sacrifice everything
to save your friends.
On the other hand, I was the hypocrite
who believed that she had the answers to all the world's problems.
It's the closest I've ever come
to seeing things through Lex's eyes.
Self-pity and blinding hubris
should be the Luthor family motto.
So if anyone's gonna win the culpability award,
I've got you by a landslide.
What do we do now?
Try and cope with the mistakes of the past and...
appreciate that we have friends who still believe in us.
Now let's go save the world.
Volume one is complete.
Shall we move on to volume two, Kara Zor-El?
Volume two?
I suppose brevity was never in your arsenal of superpowers.
Did you bring it?
Behold...
my remote controller...
preloaded with the key codes
to deactivate every one of my birds in the sky.
Brainy's intel was spot-on.
Let's find that bottle.
Hey, little guys,
Uncle Otis is gonna protect you no matter what.
Otis? -Hand over the bottle.
You didn't actually think I was gonna give you
the real key codes, did you?
No!
A word of advice?
Next time you land on somebody else's planet,
try one where the sun boosts your brain and your brawn.
Oh, but I just remembered...
for you...
there won't be a next time.
The satellites are coming into alignment.
The signal...
-It's the satellites...
Aw, somebody got a little boo-boo in their head?
-No.
We are not giving up.
Okay.
-J'onn and M'gann must've shut down the satellites. -Yeah.
I'll activate Myriad and restore normal brain functions.
I'm afraid we haven't time for any last words, Dream Girl...
It's "Dreamer."
-Who's got the headache now?
Here.
Let's hope we're not too late for Kara.
-What,
no pleading, no hopeful pontification
about how I can change
and learn to be a better person...
That's your problem, Kara...
you, Leviathan, you're all the same.
Pushing an agenda, trying to make humanity bend
in ways that it just doesn't want to.
Yeah, like you tried to bend Lena...
pitting her against me?
You're a man with alien DNA coursing through him,
thinking he knows what's best for this world.
Sound familiar?
Sounds like someone willing to do
whatever it takes to save humanity.

Well, if you're here to save the Girl of Steel,
you're one glam rock hit too late.
Are we?
-How? -You're predictable.
You can thank your sister for proving that.
You still think you can beat me?
I'm invincible.
Not if we have anything to say about it.
Welcome to mortality, Lex.
Oh, that's just embarrassing.
I didn't think this day could get any better.
A Phantom Zone Projector.
No!
Kara! No!
I won.
Careful. I bruise easily.
I'm not immortal anymore, remember?
Brainy, what's taking so long with that Projector?
The date has been wiped.
I don't know if it's recoverable
and the Projector itself...
No, we don't need it. I'll just open a transmat portal
like I did during Crisis.
No, no, no. Even if that were to work
without the coordinates of where he sent her,
she could be anywhere in the Phantom Zone.
Guys.
I found recording crystals.
Ah, yes. When I arrived,
she was in the middle of a missive.
Sort of a last will and testament.
Very dry.
You're lucky I cut her off when I did.
No, no, no, no. We're not watching those
'cause Kara is not dead.
We are bringing her home.
And you are going to wish that you were dead
while you are rotting in that cell.
Hmm. About that...
I'm not going anywhere near a cell.
Unless you want me to reveal Supergirl's identity.
She may be gone, but she still has
an awful lot of enemies out there.
It would be tragic if Mama Danvers
or your lovely Kelly Olsen
were to become the target of one of...
Sorry. Did you want to do that?
No. Family first.
M'gann and I will take him to the authorities.
Then I'll go and speak to my brother Mal.
He spent time in the Phantom Zone.
He may be able to help us locate her.
What am I going to do with Kelly?
How am I supposed to explain all this?
Kelly doesn't know that Kara is Supergirl?
Lex Luthor has been arrested
in what sources are calling a plot against the world.
Can't believe it.
Lex Luther, a bad guy?
Believe it, Mackenzie.
Lucky for us, our very own William Dey
has the inside scoop.
This firsthand account Eve Tessmacher gave you...
It's going to earn CatCo another Pulitzer.
You mean we're still in business?
After what happened with Obsidian?
Sadly, Obsidian North has folded.
But that is my father's problem.
He bought all my shares right before the company crashed this morning.
I realize in retrospect, I was undervaluing CatCo.
We could be a beacon, the crown jewel of investigative journalism.
We certainly have the talent.
And reporting in-depth, real news,
we can change hearts and minds.
We'll start our relaunch
with unparalleled news coverage on Lex Luther,
thanks to William.
Well, it wasn't just me, Andrea.
That story has a shared byline.
Kara Danvers...
She's been with me following every lead on Lex,
since I got to National City.
Oh. Well, where is Ms. Danvers?
I'd like to thank her.
She's with Cat Grant on a story.
She said it was supposed to be the biggest of her life.
Kara left town?
I guess when Cat says "jump," you jump.
Well, since Kara is exclusive to CatCo,
whatever story Cat's pulled her away to do
will be our front page soon.
Let's hope it's a doozy.
Tick-tock. Everyone back to work.
We've got a paper to put out.
Nia?
Did you speak to Kara yourself?
I just can't believe she left without telling me.
Alex told me.
I'm sure she would have called you
if she could have, William.
I want it on the record that I'm resisting the urge
to say "I told you your obsession
with the Kryptonians would end like this."
I'm glad you held your tongue, Mother.
Lena?
Hey.
I think this belongs to you.
Came in handy.
Thanks.
I should have protected Kara.
I failed.
I failed everyone.
You didn't fail, Brainy.
You defeated Leviathan.
Supergirl is gone.
Lex Luther lives.
I should have let the other Brainiac-5's take on Leviathan
because clearly I was too stupid to get it right.
Brainy, stop!
You are not stupid.
You were put in a no-win situation
and you did the best you could.
I hurt you.
That... was not the best.
You did.
But I still care about you.
How can you be so kind after...
after everything?
It's not logical.
The heart isn't logical.
When we thought you were dying on the Leviathan ship,
you said that you loved me.
If that's still true and...
you want to fix us,
you need to start engaging with me honestly,
no matter what.
Even if you think you're protecting me.
Because, Brainy,
I am not a woman who needs to be protected.
Of course.
You're a woman who stops tidal waves...
and who dreams impossible things.
And loves you too.
No more secrets?
I promise.
Hey.
Did Malefic have any advice about getting her back?
Unfortunately not.
He was only able to find Midnight in the Phantom Zone
because he knew her exact location.
He did tell me about someone who once mounted
a rescue mission there, though.
We need to get to them, now.
M'gann is already looking for him.
J'onn,
I need my sister.
Hey, the people out there...
Nia covered for her at CatCo,
but everyone else, they need to know
that she's still around, that she's protecting people.
You're not your sister,
but you're every part a hero as she is.
I've seen that every day I've spent with you.
And I saw it today,
when you summoned the strength
and belief in yourself to take down Lex Luther.
In fact, you remind me of a colleague I once had
on Mars called N'orr Cott.
We were a team.
Every time I put criminals away,
she would always stand guard
in case of a surprise escape or an ambush.
She had patience, courage and commitment,
just like you.
We called her Sentinel.
I want to show you something.
This was her symbol,
and now I think it should be yours.
Sentinel.
I like that.
We will get her back.
Until then,
together we will keep this city safe.
Sorry. I didn't mean to interrupt.
It's okay.
I came to return Myriad for you to safeguard it
till Kara gets back.
I have to admit though, I did use it
one last time tonight.
On Lex and my mother and everyone associated with them.
I wiped their minds of Supergirl's identity.
To protect you all.
I understand now why keeping Kara secret was meant to keep me safe.
But, Alex,
you really need to tell Kelly.
She's your person.
And you're going to need someone to talk to through all of this.
If you don't, you'll just end up walling yourself off.
Trust me, that won't do you any good.
Lena's right.
Kara would want you to tell her.
We will get her back.
