Previously on Supergirl...
I have decided to hold a press conference
to reveal that I'm Guardian.
You can't do that.
If they expose your identity, then you're a vigilante.
It's like the cornerstone
of all the non-lethal tech that I'm creating for J'onn.
Demos, your belt!
It turns out the Harun-El we used to kill Reign
and save Sam split them apart. But Reign is not gone.
Reign and Sam are still connected.
If Sam gets stronger, then Reign would get weaker.
My thoughts exactly.
But how? Nothing we've tried has worked.
The Fountains of Lillith.
One fountain gave infinite strength. The other brought weakness.
I'm going back to the Dark Valley.
Let us begin.
Transform this planet into New Krypton.
On Zune, they terraformed her planet's natural resources,
so they'd go right through the planet's core to create a genesis event.
Go through the Earth's core, and you get pretty close to Madagascar.
I can stop this.
It'd rip you apart.
This planet is my son's home.
I intend to save it with him.
Nice one, Mom.
- It's hurting her. - No, it's okay, it's okay.
She's gonna get through this, and stop it.
Everyone down, as quick as you can.
Get away from the building.
Superman saves Madagascar,
more from our reporter on the ground.
Kick some ass, Clark.
Our time is short, it seems.
Give them all to me.
Every memory. I can take it.
We haven't the time.
But there is one more I must give you.
This is the dawn of our kind.
She was the first keeper of the sacred scrolls.
This is the moment she received them.
My son! My son is in there!
My son's on the second floor.
- Please... - You cannot go in there.
- Please, I've gotta get him. - No one will get hurt.
Get out of my way!
- My son, I have to get him. - Listen to me.
I will get him.
You have to trust me.
No, no, no. Ah! Supergirl, the waterfront.
We're on our way.
Okay, looks like we have some help.
You didn't think I'd miss out on the fun.
You're up.
Thank you.
You're all clear, kid.
Now let's blow this thing and go home.
I assume that's some sort of film reference.
We never showed you Star Wars? Not a single Star War?
I'm sorry I couldn't give you the rest.
Don't apologize.
Don't.
I had a good life.
I'm not ready.
You are.
You looked into the flames, and you had no fear.
That's because you were with me.
That will never change, J'onn.
Never.
Live as H'ronmeer taught, among the people.
Promote peace.
And be happy...
my son.
Is it done?
Myr'nn stopped it.

J'onn, I'm so sorry.
He saved us.
Saturn Girl.
Thank you for coming back when you did.
The city would've been lost without you.
How did you know to come back?
We got Mon-El's signal.
The message from the, uh... the time beacon.
Mon-El said it broke on Argo.
It did.
Uh, the... the beacon must've had a fail-safe,
to send a message even if it powered down.
Winn, did you track down the source of the terraforming?
Or Reign's location?
- Still working on it. - What about Sam?
Has she woken up?
She's gonna come through this, right?
She's gonna be able to fight Reign.
No doubt in my mind.
No. No. No!
- Get away from me! - Shh!
I'm trying to help you.
It's not safe here.
No, you're dead.
This is a mirage. I've been here before.
I'm not a mirage.
I'm your mother and I love you.
Get out of my head!
Where is she?
Perished.
No. No, New Krypton must rise.
The Cauldron is frozen.
Dead, useless.
Crush the world to make a new.
Well, thank you for being here.
I know the circumstances weren't what you were expecting.
And I'm sorry.
Don't be.
These things happen for a reason.
It's important that we both have our closure.
This distance has made me realize
our marriage was never what it should have been.
I mean, the fact that I didn't feel I could
tell you about the Pestilence mission.
The fact I lied to you...
I'm sorry.
Yeah, but we were still pretty good partners in the Legion, huh?
The Fountain of Lillith.
No!
It's the wrong well.
This is the fountain that gives strength.
That water will kill you.
You're lying to me! Just, please stop.
This... this is the water that gave Reign the strength.
Samantha, I failed you as a mother.
And I lost you.
And I've lived with such regret ever since.
But here, I have another chance, and...
All that remains of me is my love for you.
Please, you have to believe me.
I can't make a mistake.
Drink this. Now.
Trust me, Sam.
You're smiling.
That is not good.
No, actually, Brainy, smiling is, uh... It's a good thing.
Yes, I know what smiling indicates.
But in your case, I ran a simulation,
and there is a zero-percent chance that you would be smiling
after what Imra was supposed to have told you, so...
Hey, Brainy.
Mon-El said that you, uh, want to talk to me.
Hey, sorry, Winn, just, uh...
Could you give us a moment? We're just talking about some Legion...
Oh, no. This involves Winn as well.
- Involves me? - It involves him?
Oh, yes, the Legion needs the both of you.
Killing Pestilence saved the future from the Blight.
Millions of people were spared.
Including my extremely distant relative.
The evil one,
who has created a plague to wipe out all AIs other than himself.
In short, all AIs are in danger.
And I can no longer stay there.
The future needs heroes.
The future needs leaders.
The future has leaders.
The future needs you, Mon-El.
To fight.
And it needs Winn to take my place in the Legion and save the AIs.
Uh...
What? No. Okay, rewind.
First of all, you've told me hundreds,
literally hundreds of times,
that I am far below a 12th-level intellect.
So how could I possibly be your replacement?
How'd you get this? What is this?
That's from the National Archives.
You're right.
And it's Winn's design.
The Nat... No.
They said it didn't work!
No, it didn't... It couldn't save Demos.
Regardless of what happened with your friend,
this design is the foundation
of some of the future's most groundbreaking technology.
It has saved countless lives.
And this, this dirty piece of paper,
is an artifact, treasured centuries from now.
The future needs you.
Both of you.
New world... New...
She has returned.
The Earth's core's tried to hold me captive,
but I broke through.
As I knew my daughter would.
- We must restart the Cauldron. - We will.
And then we will watch this Earth burn,
so that Krypton may rise again.
Any changes?
No.
Her vitals are weak, but they're steady.
We just have to hope she's strong enough to make it to the Fountain.
I know she will be.
She's a warrior for Ruby.
You know, you're really wonderful with Ruby.
You're gonna make a natural mother.
Yeah, and yet I haven't made any steps to, uh, make that a reality.
It took me forever to find Maggie.
So what am I supposed to do?
Am I supposed to hope that I fall in love again
with somebody who wants to have kids?
Or do I try and do this on my own?
And if so, how?
I mean, it's not like my job is conducive to being a single parent.
But then again, if we don't stop Reign,
I guess this is all just a moot point.
That's true.
But you've identified what you want, and that's half the battle.
People like you and me,
we do what it takes to get what we want.
And when we defeat Reign, I have no doubt you'll figure it out.
Wait, he wants you to move to the future?
I know, dude. It's insane.
Right?
Plus, I don't know where to begin to solve a problem like that.
Like, I don't know what Brainy was thinking,
but he is malfunctioning.
Or he's thinking you're the smartest dude he knows.
Oh, and then there's this.
And what is "Then there's this"?
Oh, you know, just my design.
Brainy brought it back from the future.
I...
Apparently, it's... It's an artifact,
and my apparatus saved countless lives or something.
Winn.
You are a genius.
The only person who doubts that is you.
Question is, what do you wanna do?
I made a shrine to, like, a cup full of dirt from the future.
- That's weird. - Shut up.
You know, and actually going to the future,
yeah, that's, like beyond my wildest dreams.
But, no, this is my home. Why...
I have you and Kara, and Alex and J'onn.
Like, you guys...
You guys are my family. I can't...
That's... That's... That's too hard.
I took off my mask today.
Wait, what?
Yeah, I took it off. I...
I met this woman with her kid, and she was in danger.
Panicking.
And there was nothing I could do to get through to her.
So, I don't know if it was the humanity in my eyes,
or my real voice.
But after I...
She instantly found her calm.
And that makes me want to unmask all the time.
But I get it, it's just...
It does feel too hard.
What happened?
J'onn's ship just sent out a distress signal.
A distress call? Why would Selena do that?
A trap? I'm just guessing.
Regardless, I've been able to access the ship's sensor.
My craft is sitting near a great power source.
I believe it might be the site of the terraforming.
But Sam is still unconscious.
We need her around if we're to stand a chance against Reign.
Actually, before you came back from Argo,
Lena figured out that she could end Reign,
with a lethal dose of Kryptonite.
Now, she wouldn't do that when Sam and Reign were connected.
- But now... - No.
I don't kill. Not even her.
There's got to be another way.
What way? You can't contain her.
You said she's grown invincible
to everything that would normally hurt a Kryptonian.
Look, sometimes, the thing we thought we'd never do,
the thing that goes against our very core,
is the one thing that we must do.
If all else fails,
and we have no other recourse, I agree.
We do what we must.
Okay. Whatever it takes.
Send Mon-El and the Legion the coordinates to my ship.
We'll meet them there.
I can't...
No, you need to drink a little more.
I can't drink any more.
Yes, you can.
Sam, do you remember?
Do you remember when you were little?
And you were terrified to go to sleep at night,
so I would sing you a little lullaby.
? Hush-a-bye, don't you cry ?
? Go to sleep, You little baby ?
? When you wake ?
? You shall have ?
? All the pretty Little horses ?
? Blacks and bays ?
? Dappled grays ?
? Coach and Six-a little horses ?
It's working.
It's you.
I'm so sorry I doubted you.
Sam, I'm so sorry for everything.
For all the pain that I caused you.
It's okay.
It worked.
Mom, you're super.
Where are they?
They went after Reign and the witches.
Don't worry, I've got this.
A force field.
They're here.
What is this, devilry?
A little piece of home.
I can't hold the force field.
You cannot win.
There is no prison you can build that can contain me.
There is no one on this planet
of equal power that can kill me.
That's what you think.
- J'onn! - Supergirl.
Mon-El gave his life to save me.
All that time I spent with my father,
I'd learned nothing.
I still came in fighting like a Manhunter.
No, this is my fault.
I came in here ready to kill her.
I knew I should have found another way.
I knew it.
I... I've lost track of what I stand for.
What have I done?
The Rock split them apart.
It could put them together.
There was a prison strong enough to contain her.
Alex.
Supergirl, did Sam get there?
She did, but I screwed up.
- I need you to find me a disruption. - A disruption?
I need to go back in time, like the Legion.
You can't breathe in space.
I'm wearing Mon-El's ring. I can breathe with it on.
If I can turn back time, I could use the electricity in the Harun-El
to take us to the Fountain of Lillith.
Okay, but it disrupts...
The pressure alone is gonna crush you.
Just find me a disruption now.
Kara Danvers is my favorite person.
She's saved me more times than Supergirl ever could.
You saved me, remember?
You taught me that my loss made me stronger.
You will do extraordinary things.
You cannot win.
There is no prison you can build that can contain me.
There is no one on this planet
of equal power that can kill me.
That's what you think.
No!
Throw me the Harun-El.
Shock us again in five minutes.
Sam, now!
Welcome home.
This one's for Ruby!
This one's for Patricia.
This one...
This one's for me.
No!
What have you done to me?
No, no, no!
No!
Well, you did it.
Just like a Greek myth, you went down to the underworld,
and slayed the three-headed monster,
and saved Persephone.
Uh, I think in the myth, Persephone eats pomegranate seeds,
and is confined to the realm of Hades forever.
Yeah, well, that just strengthens my point,
because the Greek gods have nothing on you.
I couldn't have done it without you.
No, that's not true.
This, uh... This victory was yours.
It was flawless.
What's on your mind?
Before we went to Argo, I just had this thought
that I could be Kara Zor-El, ordinary citizen.
That I would feel like I was home.
But when we were fighting Reign and the witches,
I had this moment,
this realization
that Argo City's not my home anymore.
National City is.
Earth is.
And my mission is to protect it.
I mean, my whole life is here.
- Yeah. - Messy, complex.
Balancing Kara and being a hero, that's...
That's who I am.
I have loved fighting by your side.
Being there through all of it,
the ups, the downs, the particularly tough days.
You know, for a moment there, I thought that...
that maybe this was my...
my place,
my time.
But I learned some troubling things today, uh, about the future.
I need to go back.
I can't abandon the Legion.
Or the world that I swore to protect, right when they need me most.
I know you can't.
You wouldn't be the man you are, if you did.
The man I admire so much.
Well, I guess we both got some saving to do.
Hey.
It's about time you had one of your own.
Thanks.
In case you ever need me.
Hey, you guys.
Hey. Oh, my goodness.
Oh, yeah, I'm... Okay.
Well, I came to say thank you,
but I think Ruby just did that for the both of us.
Yeah.
You made me feel safe when everything was horrible,
and you made me have faith that my mom would get better.
And I don't know what I would've done without you.
Well, I mean, you're a pretty great roomie.
So, wanna give the good news?
Sam, all your blood tests came back, and they are normal.
There is no trace of any Kryptonian DNA.
You are 100% human.
Thank you.
Come here. Thank you.
Oh, God, thank you.
Hey.
I gotta go.
I've been...
I've been searching for my calling, you know. This...
This is it.
I must save the future.
What about you?
I can't keep waiting on the world to change.
My future's now.
I don't know how much longer I can do this, J'onn.
I put my life on the line every day.
And every day, I run the risk of losing it.
And I feel like I haven't even had the chance to really live it yet.
I'm afraid that if I don't make a move soon, right,
if I don't reach out and take hold of my future, of what my heart wants,
then I'm never really gonna be happy.
So, that said, I, uh...
I wanna give notice.
So that I can find my new beginning,
and I can have a family of my own.
You're a hero. It's in your blood. You can't resign.
Because I want to promote you.
This year, I have had the most priceless gift.
I found my father.
I lived with him, I learned from him.
He reminded me that the Martian way is to live amongst the people,
and to help them.
Not hiding behind walls, like I have been here,
but with open hands and compassion.
You're stepping down?
I am.
But I am not leaving you.
I would never leave my family.
Alex...
- Uh... - I want you to run this place.
Be the director.
With you in charge, I feel the DEO will stay on the right path
to protecting this planet,
and helping those who cannot help themselves.
And being in charge,
you won't have to put yourself in the field all day,
risking your life.
You don't have to deny any part of yourself to be complete.
You can have a family.
And you can be a mother.
All on your own terms.
Congratulations, Director.
That's not how I saw this going.
Thank you.
- Congratulations, sir. - All the best.
He's a hero.
So are you, Kara Zor-El.
I am so proud of you.
You stuck to your ideals,
and found a way when there was none.
I will miss you, my daughter.
I love you, Mom.
I love you.
And I will bring Selena and the witches back with me.
They will stand a just trial, I promise you.
Good.
Uh...
Lena.
This is the Harun-El your daughter asked me to make.
And the recipe to make more.
Thank you.
With this Harun-El, Argo will survive.
Though I hate to depend on it.
There's so many things that we don't know about it.
Its uses, its powers, its dangers.
I'm so glad that none of it will be left on Earth.
Agent Schott.
You have been a fine agent,
and a spectacular friend.
I'm gonna miss you too, Papa Bear.
Do not tell Clark I taught you that.
No promises.
- I'm gonna miss you, man. - Yeah.
You were the first person I told I was Supergirl.
You made my suit, kept it safe.
You've been a true friend.
I'm really gonna miss you.
Okay.
I'm gonna miss you guys.
Come here.
Come on.
Eh... Ahh!
Hey, incoming. Incoming!
The future's gonna be a steep learning curve.
- To saving the world. - Hear, hear.
Mmm. Excuse me.
Yeah.
Oh, I have a comment.
I'm the Guardian.
We can now confirm that CatCo's
very own James Olsen is Guardian.
He did it.
How about Winn joining the Legion?
Do you think he'll make them new outfits?
Oh, absolutely.
I still can't get over J'onn.
Following in his father's footsteps.
Leaving the DEO.
I did not see that coming.
Yeah.
What about you,
Director Danvers?
You're just so brave.
Yeah, look at you. Okay?
I mean, leaving your mom after you just found her,
coming back to Earth.
I mean, that takes courage.
Mmm.
I just realized that everything that makes me me is here.
This is my home.
With you.
On this couch,
with this insanely huge pizza that we just downed.
There's no pizza on Argo, huh?
- Nope. - That's a shame.
You have no idea how happy I am that you came back.
Are we gonna be okay?
We're gonna be okay.
Ms. Teschmacher,
we're ready to begin phase two of our trials.
Throw me the Harun-El!
