Supergirl

Previously on Supergirl...

My fiancee died fighting on the front lines.

I saw Alex almost die.

Give me the medallion.

Can you translate these markings?

I got something from Rip Roar. A name.

Leviathan.

I can use Supergirl to achieve my ends.

That is easier to do if she believes there is trust.

Malefic's back in the Phantom Zone.

You like it here, don't you?

I like it very much.

You're off your game today, Supergirl.

I could say the same to you.

Not so fast.

I need to be ready.

We don't know when Leviathan will strike next.

We don't even know what it is.

And what are they after?

All these unknowns make me feel anxious.

And when I feel anxious, I want to punch things.

We've faced unknown dangers before.

This feels different.

I have a bad feeling about it.

Well, Alex has the DEO working overtime on Leviathan.

Are you sure something else isn't bothering you?

Before I told Lena I was Supergirl,

I was terrified how she would react.

I was so afraid I was going to ruin the friendship.

Ugh. I still hate thinking about it.

Watching William lose his friend

hit a little too close to home.

J'onn? J'onn?

You can come out now.

Give me the medallion.

I don't think so.

I have the most intricate security system in the world.

I know all about Leviathan.

No one knows all about Leviathan.

Leviathan is unknowable.

I'm not afraid.

You will be.

She's gone.

I've reactivated heightened penthouse security.

You were right as always, Ms. Luthor.

Leviathan will attempt to retrieve the medallion at all costs.

But why would you provoke them over something of no value?

It has value to me.

The medallion was special to my mother,

and the fact that Leviathan wants it makes it useful.

Lex theorized that Superman kept every weapon

that was ever used against him in a special facility, a fortress.

And although he never found it, I think Lex was right.

I think the perfect dispersal device

for Project Non Nocere is hidden there,

gathering dust.

And Leviathan is gonna help me find it.

Please don't underestimate the danger of Leviathan.

You should cancel the L-Corp event at the park.

They will come after you.

Let them come.

Supergirl will save me.

Tell us exactly what happened.

I already told you, I'm fine.

Alex, you should be tracking Leviathan.

Yes, and Rip Roar, but Brainy's on that,

so just stop deflecting.

Before I fell, I was seized by another vision of Malefic.

"Another"? You've had more of these?

Yesterday. I felt Malefic during the psychic attack.

It's as if I can sense him all around me.

But how? We sent him to the Phantom Zone.

All I can think is these flashes are...

maybe symptoms of my guilt.

I know we had no choice but to send

Malefic back to the Phantom Zone, but...

I mean, he's too dangerous to be contained here on Earth.

Even so, I can't help feeling

I've wronged my brother again.

This is the third time

he's been sentenced to confinement by my hand.

No, your brother made his own decisions.

You can't blame yourself for that.

But it seems like you're going through some sort of trauma.

Maybe Kelly can help.

She can't provide the help I need.

I'll deal with this the Martian way.

Where's the medallion?

I...

I couldn't retrieve it.

It was a simple task.

It would have been simple with any other human, but...

she is a Luthor.

Do you know how long that I've been safeguarding this planet?

Since the beginning.

And since our ship, as big as an asteroid,

wiped out the dinosaurs.

Then humanity rose...

and became a scourge to this planet,

and for eons we have kept

their destructive behavior at bay, but now...

They're ravaging the Earth like never before,

and I granted you the privilege

of serving our cause, and you failed.

Is it her failure, Rama Khan?

Or is it yours?

You can go, Margot.

Using a carrot instead of a stick

is not what we need right now.

Well, they are known as the "snowflake generation."

So what does that mean, they melt?

Never mind.

You and I both share the same goal...

of wanting to put a stop to people who disrespect this planet.

I'm here to offer my help.

How can you help?

The world is shifting, evolving.

Moving faster than it ever has.

We have to remain ahead of the curve.

The old ways aren't working...

Oh, the rising of oceans and the raging of rivers will always work.

Give the brute force a rest, Rama Khan.

Let's try my technology.

Our elder left the caretaking of this planet to me...

for a reason.

You want something done, you have to do it yourself.

Thank you all for coming on such a wonderful day.

What was that?

Running these trails has always

been my favorite way to clear my mind.

- What was that? - Did you feel that?

It means so much to me

that L-Corp can have a hand in preserving these grounds.

You have something that belongs to me.

What was that?

Leviathan.

Thank God for selfie culture.

Because of this generation's constant need to livestream everything,

we've got a clear image of your attacker.

And I knew I had seen that face before.

Do you recall Antioch, 526 AD?

It was an earthquake.

It was the eighth-largest natural disaster in modern history.

Precisely. It's good to have you back, Lena.

A myth was born that this man was the cause.

Now, of course, scientists insisted that

the natural disasters were natural,

but, in an ironic twist of history, they were wrong...

and the fearmongers were right.

Several reliable sources place

this man at the scene of the crime throughout history.

Pompeii, the Yellow River flood of 1887, the Bhola Cyclone,

even as far back as Noah's flood,

this Earth-Bender has been spotted.

Excuse me, did you say "Earth-Bender"?

How else would you describe him?

He... He literally manipulates the earth.

Wait, Pompeii? Noah's flood?

I mean, what is he, thousands of years old?

Correct. Which means that he is an alien

with powers of longevity this civilization has never conceived of.

No wonder people thought he was a myth.

With all this destruction, his existence is still shrouded in mystery.

He's managed to convince the world he doesn't exist.

It seems so.

The word "Leviathan" occurs six times in the Hebrew Bible.

Never once does it appear in any historical scientific literature.

So how are we supposed to fight a highly secretive, thousand-year-old alien

with powers that we have no idea how to beat?

Well, I know one person who spent his life fighting aliens,

- both real and imagined. - Your brother.

I know most of his minor weapons are in Fort Summit,

but his truly horrendous ones, they were all destroyed by Superman.

That's not necessarily true.

A lot of Lex's weapons are in the Fortress of Solitude.

Oh, it's... It's a place Superman created.

We keep things there that can harm us.

Well, you just go to the Fortress,

and I'll give you a list of every weapon that Lex ever created.

Why don't you come with me?

I mean, there's no telling what weapons we'll encounter.

And then, Brainy and I will stay here, and we'll continue our search

for Rip Roar and this Earth-Bender.

Supergirl, remember the strongest,

most potent weapon is knowledge.

So send me whatever you can find from the Fortress database.

You ready for a road trip?

Are you sure me going is a good idea?

Of course. Why wouldn't it be?

I don't know. A Luthor in the Fortress of Solitude?

It's gonna be great. But you're gonna need a jacket.

Father,

I haven't been this lost since after I killed Manchester Black.

You came to me then.

You helped me find myself.

I need your help now.

J'onn, my son!

Father. It's good to see you.

I am... I am so sorry.

I know now what I did.
