Previously on "The 100"...
Luna, you're the last of your kind,
the last Nightblood.
Will you take it and become
the next commander?
No.
We take people in who are done fighting,
done killing.
Skaikru made me murder my entire family.
I have no one left.
I'm sorry for your loss,
but the chip, the technology,
it affected all of us.
I, King Roan of Azgeda, am caretaker of the throne,
and keeper of the flame.
The flame won't keep the clans at bay forever.
If they unite against us--
they come for Skaikru.
And the radiation comes for us all.
Aah!
We have to focus on riding out the radiation,
finding someplace safe.
That's it.
We're standing in our viable solution.
How many of us will the ship sustain
without a hydro-generator?
No more than a hundred.
Two meals a day for people working as hard as ours,
we won't make any friends.
Well, if there's one thing
our people understand, it's rationing.
Besides, once we close those doors,
it'll be one meal a day for the next 5 years.
Try one meal every other day.
Hunting parties are coming back with less and less.
Thanks to your friend Niylah,
we're preserving more meat than ever,
but it's still not enough.
Without a way to make water, growing our own protein
like we did on the ark is not an option.
Remember that when we're starving.
I won't be starving
because I won't be inside.
Yes, you will.
Does that mean you made the list?
No. What about drinking water?
Clarke, don't change the subject.
We need to know who's gonna be on the inside
of these doors when the radiation comes.
We don't need to know now.
We need some medical help at the front gate.
Looks like we got some sick people there.
Do not come any closer.
Please. They need Skaikru medicine.
Move. Stand back.
Nyko.
What if it's a grounder attack
like they did with Murphy?
What happened to them?
The sickness.
We lost more than 40 on the way.
Luna?
Please don't turn us away because of what I did to you.
Out of my way. Please let me through.
Mom, what is this?
Fever, lesions, vomiting.
- It's Ars. - What's Ars?
Acute radiation sickness.
When did the symptoms start?
Not sure.
Right before the fish started dying.
The fish are dying?
Floating on the sea to the horizon
in every direction.
It's not contagious. Let's get them to Medbay.
- Come on. - Uh, uh...
Come on.
I got you. OK. All right. There you go.
It's already here.
It's not safe for you here. What do you want?
I need you to handle something for me
the way you handled ambassador Rafel.
We should speak alone.
If you can't trust Indra,
you can't trust me.
The flame's been stolen.
How? When?
Just now from my quarters
while I was training.
How can you be so careless?
We need to lock down this city
and search everyone.
We can't.
If word gets out that he's lost the flame,
the other clans will question his rule,
Trikru loudest of all.
Then I'll be forced to answer their questions with my army.
Or we can just find it. Where do I start?
Whoever did this got in and out
of the tower without being seen.
In order to risk that, she'd have to care more
about the flame than her own life.
- "She"? - The new Flamekeeper.
Perhaps you should look closer to home.
You're not exactly beloved.
My people want an ice nation king.
The ambassadors don't.
The ambassadors are cowards
and know I'd have their heads,
the keepers of the flame--fanatics.
I'd do it myself, but my guards
won't let me out of their sight.
I'll handle it.
What's wrong?
You created a killer.
In the street, they're calling her Skairipa,
death from above.
- I'm so proud. - You should be.
One kill to prevent thousands,
that's good politics.
You said there'd be food here.
There should be.
These woods have always been good to me.
Now there's not even bugs.
Well, fortunately, I'm not hungry enough
for that to be upsetting yet.
I actually kind of miss Polis.
They had this drink there--
sweet, made out of sheep's milk.
Ontari gave this to you?
Yeah.
I told you, it wasn't all bad.
You told me you were trying to survive.
I was.
What else wasn't bad, John, sex?
Emori, I don't want to talk about this.
Fine. Then let's not.
I didn't have a choice, OK?
Emori...
I didn't have a choice.
Where are you going?
I'm gonna go to Arkadia.
What? Why?
I'm a better thief than I am a hunter.
- I'll come with you. - No.
I'll draw less attention alone.
- Tonight we feast. - OK.
They're getting worse.
There's got to be something we can do.
Delactivene might help,
but Raven's got the meds on lockdown.
Leave Raven to me.
What, exactly, do the tests show?
The exposure is acute.
Without treatment, there's little to no chance of recovery.
It looks like the radiation is internal,
ingested from irradiated fish.
None of the outbreaks appear
to be from airborne exposure.
- That's the good news. - Not for them.
You think I deserve this for refusing the flame?
No one deserves to suffer.
Besides, this would've happened anyway.
It's worth a try.
This is all that's left of my people.
Can you save them?
We'll do everything we can.
You have my word.
Tell me something good.
Raven's looking for us.
So Luna's rig is here, and if the fish
in these waters are dying,
well, basically, we're screwed.
I don't understand.
Alie said we had 6 months.
We don't.
Well, then how long do we have?
It's hard to say.
Radiation is dispersed by jet stream
and carried by ocean currents,
so it's not an exact science,
but the leading indicators are small species die-offs--
fish, insects.
Based on the new data, I'd say we have...
Two months of survivability...
Maybe less.
The ark won't be ready.
It'll be close.
If we triple the man hours and work round the clock,
we should be able to achieve a hard seal
before the black rain comes.
We just have to decide who gets to live here.
Raven, we're not talking about the list again.
Clarke, we are running out of time.
We have to make a plan for the day we close the doors,
drill for it, make sure
only the survivors have guns,
agree on protocols for dealing with the people
who are pissed off they're not chosen.
You asked me to be in charge of rationing,
and I am doing it, but choosing
who gets to live or die is your specialty.
No one's scheduled to take the rover.
Out of the vehicle.
I need to make a run.
All supply runs go through me,
and shouldn't you be working
on the patch to sector 5?
A patch for a ship
that can only save a hundred people?
Why are you surprised?
I am an engineer.
We have no way to generate water.
The harder number is 400.
Can you really sentence 400 more
of our own people to death?
We don't have a choice.
What if you do?
What if I told you there might be a fallout shelter
less than a day's drive from here,
a fallout shelter built to sustain thousands?
We've been through the chancellor's files.
All the bunkers you considered for the hundred
were listed as compromised or unviable,
and now mount weather is, too.
Those were government bunkers.
A doomsday cult?
That's right-- the second dawn.
They built a bunker?
Their whole theology was based on riding out
the end of the world.
And why didn't you consider it?
We couldn't prove it existed.
So why are you considering it now?
Because before now, we didn't need it.
You found it, didn't you?
We can't be sure unless we check it out.
No. No way.
We need that rover for hauling pieces
of a 3-ton patch we're build--
yeah, but if he's right, we don't need a patch.
Can I talk to you guys for a second?
Can you please remind Clarke
what happened the last time Jaha
went looking for salvation?
Raven, if that bunker is real,
we can save a lot more than a hundred people.
If it's not, we've lost another day.
Hey, look. If it's not, I'll make the list...
OK?
Oh, do what you want. I've got a ship to seal.
I'll drive.
The end is coming.
Hear me as I say it this time.
The end is coming, and it's coming soon.
He gave this speech two weeks before the bombs.
The world is dark and getting darker all the time.
Everything we once trusted has turned on us--
government, religion.
Even technology has become a weapon in their hands
used to poison our minds.
I know you're in pain.
I know you're afraid, but it doesn't have to be like this.
There is a way out of the darkness.
I can show it to you. You can be saved.
Join me.
Join us, and together when the horsemen come,
from the ashes, we will rise.
Please tell me you have more than this.
In the two years before the bombs,
Cadogan sold off most
of the second dawn's real estate holdings,
generating tens of millions of dollars,
but there was one thing he didn't sell.
I found this in his autobiography.
It's his childhood home.
His father build a bunker there to save his family.
I think Cadogan used the church's money to expand it.
Grew up there.
Maybe he kept it for sentimental value.
Hmm. His father beat him almost daily in that house.
He hated living there.
Why keep it if you're liquidating everything else?
Because that bunker is there. I can feel it.
Guy sounds like a religious fanatic to me.
Maybe, or maybe he was just a leader
willing to do whatever it took to save his people.
Look who's back.
Thought you ran off with your...Girlfriend.
You jealous, Miller?
There's enough of me to go around.
Of course, Bryan would probably kick my ass, so--
You here to stay, John?
Till something better comes along, yeah.
Close the gate.
All right. Start it up.
Already told Jackson, we can't spare anything,
especially not antiradiation meds.
We're talking about 7 doses.
That's a quarter of our supply, Abby,
a supply that has to last us for 5 years
on an irradiated planet.
We're gonna need every one of those pills,
and you know it.
You're right.
We put you in charge of the supplies.
It's your call, but those people--
will it work?
Can you guarantee the medicine will save them?
You can't
because Delactivene needs to be used
within 24 hours of exposure.
It's on the damn label.
The rate of effectiveness goes down,
yes, but it doesn't mean it won't work.
- We have to try. - No.
There's a child in there with them.
At least give me enough for her.
I'm sorry, but we can't waste our supply
on a long shot.
If we can save one life,
would you call that a waste?
Even if it worked, even if we could save them today,
they'll be dead from radiation inside two months.
You tell yourself that if you need to,
but the radiation isn't killing that child.
You are.
You looking for these?
Where did you g-- never mind.
I didn't know how many you needed,
so I took it all.
What are you waiting for? Go. Be doctors.
Give it to the child first,
and if it works,
you give it to the others.
I'm glad you're back, John. I was worried about you.
Thanks.
OK.
It's OK. OK? It's OK.
Adria...
It's OK.
You can trust them.
It's like food.
Just put it in your mouth
and take it down with the water.
There you go. That's it.
Easy, easy. OK.
I got you. I got you.
What about the others?
We'll monitor Adria closely for the next few hours.
If her symptoms improve, then we'll treat the adults.
Thank you.
His father got floated
for stealing medicine to save him.
Who knew he had it in him?
I did.
Hey, no, no, no.
What's the point?
Alie used tech to control us.
No one'll ever take over our minds again.
So you're the new Flamekeeper.
This is a sacred space. Leave before you get hurt.
Give me the flame.
It does not belong to you
or your red-blooded king.
I can't let you leave with it.
You don't have a choice.
Ah!
Good technique. I know it well.
Uh! Yah!
Stop. Put down the sword, Octavia.
- She has the flame. - She's my daughter.
I'll talk to Roan.
If we give him back the flame,
I can convince him to show mercy.
Azgeda knows no mercy.
Give me the flame, gaia.
It's around her neck.
That's nothing, a totem she's worn
since she joined the faith.
You are interfering in matters you do not understand.
Wrong. I'm a Flamekeeper.
I'm honoring my faith,
a faith you once believed in.
Don't you question my devotion.
A devoted follower would die
before giving the flame to an unworthy king,
an Azgeda king.
You pervert our faith. Heda would be ashamed.
I'm doing what's best for Trikru.
You would understand that if you had stayed
and done your duty.
I was called.
My daughter was not meant to wander the earth
looking for Nightbloods.
My daughter was meant to lead armies.
My daughter was meant to lead our people.
Looks like you found that daughter now.
Roan sent me here to kill you.
If I don't come back with the flame,
he will send others.
If the spirit of the commanders
deems it my time, then so be it.
Indra,
tell me what you want me to do here.
Without the flame, the king is vulnerable.
We will need to fight to keep him on the throne.
If that's what you want me to do,
I'll do it for you.
- I can run. - He'll find you.
Don't throw your life away.
That's what you said the day I left.
You still don't understand.
The looters.
If they find the flame, they'll destroy it.
I'll take the tunnel.
Wait.
Drop your weapons.
You're making a mistake.
We just want the tech. No one has to get hurt.
Uh! No.
Give me the pack.
No. No. Let go. Give that back.
Don't. Uh...
Please. That's not tech.
That's the spirit of the commanders.
Please. Ilian, you don't have to do this.
Yes, I do.
- Yaah! - Aah!
Whoo!
They're gone.
Ohh...
Sorry about your necklace.
Don't be. That was a good plan.
Thank you.
You got what you wanted.
So did you.
Indra...
She's family.
Roan will still want her head.
Not if he doesn't think it was her.
Hey, hey, hey.
What the hell are you doing here?
Now is not a really good time.
Once a cockroach, always a cockroach, huh?
Seriously, Raven, not now.
Oh...
We only wasted one dose.
Ohh...
Ohh...Ohh...
Cadogan learned how to survive from his father.
They hunted in these woods.
Huh.
This is it.
Well, if anyone's entitled to a lucky break, we are.
You hear that?
No insects.
What?
Luna said the fish were dying.
What are the things that eat the fish
and bugs gonna eat now?
What happened to us deserving a lucky break?
So what are we looking for?
The bunker would have been at the lowest point.
Anything structural. Be careful.
She's lucky to have you.
Leadership is a lonely pursuit,
but you--you keep her centered.
You got it backwards.
Still blaming yourself for killing that army.
You made mistakes-- it's true--
but your intentions were pure.
Every choice you made you made to save your people...
Even shooting me twice.
As long as that's the truth, you don't need redemption.
- You better hope so. - What's that?
Well, if you're wrong and there is a hell,
then I guess I'll see you there.
How many people do you have to save
before you forgive yourself?
Over here.
Huh. Stay behind me.
Watch your head.
OK.
"From the ashes, we will rise."
Not this guy. Hmm.
The 11th seal.
Their faith was based on 12 seals.
Followers could level up
by unlocking them one at a time.
Only those who reached level 12
could achieve salvation.
Huh. Maybe that's why they didn't let him in.
I was right.
What if they're still in here?
Hey! Is anyone there?
It's still sealed.
There's no locks, no handles.
That's because it was designed to be opened from inside.
Or from the outside by somebody with a rover.
What happened?
Let's go find out.
It worked.
Huh.
This can't be.
It wasn't sealed.
The radiation would have killed them in days.
This won't save anyone.
Leave us.
He was one of the looters.
You were wrong about the Flamekeeper.
And the flame?
Destroyed before I could kill him.
I'm sorry.
It'll be more dangerous now.
More people will have to die to keep me in power,
not that that bothers you,
Skairipa.
People fell in line behind the flame.
Now they'll fall in line behind the sword.
Let's hope Clarke finds a way
to save us before they have to.
Get out.
Oh, finally.
Emori.
John, what's wrong?
It looks like we may need my people, after all.
There's a storm coming.
When it hits, we need to be
on the right side of that door.
So we make ourselves useful.
Yeah. Yeah, exactly.
I've already started working on Abby.
Come on. I'll explain on the way.
Mm...
If I'm on that list, you're on that list.
- Bellamy, I can't. - Write it down.
Write it down, or I will.
So what now?
Now we put it away and hope we never have to use it.
You still have hope?
We still breathing?
Get some sleep.
Luna?
Impossible.
We didn't treat her.
Your fever's down.
How?
Her body's rejecting the radiation on its own.
Here. Please sit down.
I'd like to run some tests.
Jackson.
What did you do?
Nothing. There's only one variable.
There's one thing that separates Luna from the others.
Nightblood.
From the ashes, we will rise.
