[narrator] Previously on The 100:
[Sheidheda] I ask only that you take a knee to show your loyalty.
The killers and the thieves are at your service.
If you try to come in here, I blow the reactor.
[Sheidheda] Stay here and wait them out. When the door opens, kill them all.
- [Cadogan] She has the key. - [Clarke] The Key is the Flame.
Is my daughter in the Key?
If I can get the Flame, you can find out.
My Shepherd... Clarke doesn't have the Key.
All of you will die if I don't give him the Flame.
I'll take you to it.
[dramatic music playing]
What the hell happened here?
[suspenseful music playing]
Russell...
What the hell is this?
Who the hell are you?
That's not Russell.
This is Malachi Kom Sangedakru.
And you will kneel before him.
I guess we found Sheidheda's code.
Since my ascension, protocol has become rather simple, really.
Kneel or die.
Ordinarily...
I would relish the opportunity to recruit your forces to the Cause.
But, unfortunately,
I have neither the time nor patience to suffer your primitive tribalism.
[Clarke] Murphy!
Invisibility and ray guns I can accept.
That needs some explaining though.
Tell me Madi's safe with Gaia.
We thought Gaia was with you.
Madi's safe for now.
Restrain the soldier with him.
- No. - Hey, hey!
- She's with us. - [Kelly] Let's go.
She was standing unrestrained by the throne.
The only reason she is not dead is, she was unarmed.
[yells, then grunts]
The microphone.
That wound is deep.
I have no interest in removing you from your throne.
Here's my proposal.
You give me undisturbed passage to get what I came for...
That means I see not a single soul on our path.
...and I leave Dr. Santiago here to treat you.
When we're gone, you're free to continue the debasement of our species
until you're saved, like the rest of humanity, by the completion of my quest.
Refuse this and you die.
[mutters indistinctly]
Right, then.
Onward to the Key.
[theme music playing]
[indistinct chatter]
That's Russell Prime's dog. Not yours.
He wouldn't want a COG petting her.
Come on. You know you wanna pet her.
[tender music playing]
I bet she's hungry too.
I'll be right back.
Everyone's hungry. How is Jackson gonna get our rations past that?
John Murphy will think of something. We're safe now because of him.
I have faith.
No offense, but if our lives really do depend on Murphy, we're screwed.
[Cadogan] A fire-burned castle surrounded by a city of garbage dumpsters.
[man on PA]...stay out of sight.
[Cadogan] Everywhere human beings go is worse off for it.
But thanks to us, we will transcend.
Thanks to us, we will reach the Promised Land.
For God's sake.
- Hey, so what's our play here? - No play.
Don't get me wrong. You look good. Not as good as me,
but I know a thing or two about pretending to be something you're not.
This isn't an act, Murphy. I'm trying to save us all.
I don't expect you to understand.
Just know, I am your friend. I'm looking out for you.
That's very reassuring. I'm just gonna...
All right, tell me he's not serious.
Welcome to the party.
Hey, I'm not gonna lie, feeling a little out of the loop.
Mutual. You said that Madi was safe "for now." What does that even mean?
She's safe. She's with Emori...
in the reactor.
I know, I know. But, believe it or not, it was the safest place in Sanctum.
What the hell's been going on here?
Hold.
[Clarke] Look, I'm in a hurry.
You have our friends.
I would like them back, then to see my daughter.
If you wanna see yours, the Flame is this way.
- New plan. - [Clarke sighs]
You go. We'll stay here.
[Bellamy] Sir, you heard her.
As long as her friends are out there, she won't risk their lives.
That's why these two are staying with us.
Hurry along, Clarke.
I don't wanna be on this infernal moon a moment longer than I have to.
[suspenseful music playing]
Well, what do you say we wait in the tavern instead?
- [yells] What the hell? - You get used to it.
Yeah?
Come.
I like this spot. High ground.
So Sheidheda's alive, and Madi's in a nuclear reactor?
You did good.
All of our friends are missing, and Bellamy is a sheep.
[softly] So did you.
[man] All right, give me a hand.
[Musgrave] Be happy you don't have to clean up the blood.
Now, if the blade hit your kidney, there's not much that I can do for you out here.
And something tells me they won't take you to Bardo.
Good. It's time we let him find out what death is like a second time.
She'll miss me when I'm gone.
Did he suffer?
Who, Russell?
No, it was quick.
[Josephine] Oh, come on. Like you care.
What's the matter, Gabriel? You don't look happy to see me.
No.
- No, no, no. Not now. - What's wrong?
Don't tell them. Just say you need Band-Aids or something
for whoever's wearing daddy's last body so we can be alone.
I need antitoxin. Suns are eclipsing.
Oh, for Prime's sake.
When that happens, the trees release a toxin...
That drives everything mad. I'm aware.
It's nighttime, there are no suns. How can you be sure?
Because the Red Sun paints the planet we're orbiting.
I'm already feeling the effects.
[dramatic music playing]
So just to recap, the Shepherd right over there is the same guy
who built the bunker that saved humanity from Praimfaya twice.
And he now wants the Flame, broken by you, so he can start a war with...
whoever built the Stones,
in order to turn all of us into beams of light.
Yep.
Huh.
Is it weird that, to me, the craziest part of all this is Bellamy's robe?
Nope.
Echo and Octavia are hostages, and look at him.
Yeah, well. Not to point out the obvious, but we're hostages too.
Yeah, something happened to him out there.
- [Cadogan] What's taking her so long? - She'll be here.
I know how hard this is on you, son.
Believing in something with all your heart that the people you love don't understand.
You remind me of myself when I was young.
- Would you excuse us, please? - Of course, my Shepherd.
Doucette's a good man. He'll make a fine replacement for Anders.
- But he's not like us. - Sir?
The Disciples are taught our ways from birth. They know nothing else.
Makes faith easy.
We, on the other hand, know the pull of love between individuals.
What it makes us do. The highs and lows of it.
How it leads to hatred of the other.
Tribalism.
I've spent generations dedicating my life to something greater.
Transcendence.
Now you know the weight of that too.
The path of a prophet is always hard. Your friends will understand eventually.
You had a family.
How did you manage it?
I feel like I'm failing both you and them.
You're not failing me, Bellamy. Far from it.
You're special.
You were given a glimpse of what comes next, just as I was.
They all think I'm crazy.
And so we ignore their judgments and we save them anyway.
For all mankind.
- [Gabriel on PA] Attention, Sanctum. - What is this?
Red Sun toxin has been detected.
Make your way to your assigned location for evacuation.
Let's play another round of "Who Wants to Murder Your Friends?"
We should get you back to Bardo.
I'm not going anywhere without the Flame.
For all we know, this is another one of Clarke's tricks.
If it is, then it's a good one.
[alarm blaring]
Attention, Sanctum. Red Sun toxin has been detected.
Bugs.
Make your way to your assigned location for evacuation. This is not a test. Go now.
It's okay. We're safe. The reactor's airtight.
- Toxin can't get in. - [thud, then men grunt]
It won't be airtight for long.
They're calling our bluff. They know we won't detonate the reactor.
[Gabriel]... Sanctum. Red Sun toxin...
Trey, Jeremiah, get everyone into Secondary and seal the door.
Go! You too. We've only got one gun.
[dramatic music playing]
Surprise.
- Dad! - It's been swell, but I think I'll be going now.
You're cute, but I will kill your daddy if you don't step aside.
He knows we can't let you open the door.
[Emori] Nikki, it's true.
Look.
If those men open that door, Red Sun toxin will spill into this reactor.
Human shields only work if you're not willing to let the other person die.
Shield. Here.
The hell are you doing?
Stop, or in three seconds, this kid's fatherless.
One.
Two.
- Turn on the damn lights or I cut this... - [blow lands, body thuds]
[banging on door continues]
You let the bugs in?
Yeah. Two bugs with one stone.
I just hope it's not three.
- [man 1] Let's go. Come on, follow him. - [man 2] Let's go, let's go!
Let's go. Everybody move!
We should be going with them to Ryker's Keep.
Or maybe you'd like to drown me again in the pond.
[Raven] Power's out. That means the shield's down.
Guys...
[suspenseful music playing]
- We should run. - She's right. We should go right now.
Not without the Key.
[Doucette] I agree with Bellamy.
We should execute the hostages and get you home.
Bellamy never said that.
Clarke heard the alarm too. She'll go for Madi.
Yes, right. Good. The reactor.
Perfect. I'll get the power back on. Kill the bugs.
Or they kill us. Everyone, grab a torch!
Sir, stay with me.
[alarm blaring]
He's the last one.
I sent saline ahead to Ryker's, just make sure the IV stays in.
[man] Will do. Hey! Where do you think you're going?
- Hey, wrong way. We're evacuating. - It's okay.
- Go! - [Josephine sighs]
It's good to be back.
Not sure how I feel about all the old me's being turned into a chair,
but, hey, I do believe in recycling.
[Jackson] Dr. Santiago?
Dr. Santiago, right?
You okay?
Antitoxin.
Get him to the Keep. I'll be right behind you.
[grunts]
Mmm, Josephine Il. I liked that body.
[Jackson] Where are the others?
- They went looking for you. - Right. Yeah, that's a long story.
We don't have much time.
Just tell me if Nate's okay.
You have no idea who that is, do you?
- Nate? - Miller.
Of course. Yeah, um, Nate's fine.
- Is he here? - No, but he's safe.
Ah, there you are.
Almost empty.
The Primes used it to get to space after Russell threw the bomb.
All the ingredients are here. We can make more.
This one's yours.
It's the only dose. I don't know how to make more. You take it.
Yeah, Gabriel.
You take it.
I'm used to working under the influence of the toxin.
You're not, and I really need your help.
Oh, I missed you too.
- Be quiet. - Excuse me?
Nothing.
First, we steam-distill the actual toxin into a supersaturated solution.
Three grams per milliliter to start.
Copy that.
God, it's sexy when you get all science-y.
Not now.
Why not now? Who cares about these people?
Let them tear each other to pieces. All we need is the Flame.
You're a "Nightblood." We fix it.
We put it in your head and save humanity.
I know you're thinking it or I wouldn't be.
Becca Franko designed the mind drives and the Flame.
They speak the same language.
We can repair the code.
Different connections.
Gabriel, you engineered memory drives to hold entire minds.
Consciousness.
On Skyring, you used a damn Etch A Sketch
to watch the Colin Benson Show.
Surely you can rig some Eligius tech to pull data off the Flame.
You can solve the mystery of the Stones.
Start the Last War, the test, whatever.
No. No.
Not for Cadogan.
For you, then.
You've got the blood. Not him.
You take the test for all mankind. We level up because of you.
What better way to make up for all the things you did in this lab to conquer death.
Hm?
All the broken eggs it took to make this omelet.
What do you say, my love?
We came across the stars to save the human race.
Now's your chance.
[suspenseful music playing]
[men yelling]
[man] Get them off!
[Trey] It stopped.
[all screaming]
[Bellamy] This way. Here we are.
[Murphy] We don't have much time till the bugs come back.
[Doucette] Scatter them!
Let's get the door opened. Seal the windows. The swarm's still outside.
[Clarke] Wait. Hold the door.
[Raven] Clarke!
What's in the bag?
Antitoxin.
- From the farmhouse. - For your daughter?
Enough for all of us. But, yes, I was thinking of Madi before you.
Another lesson in the destructiveness of familial love.
[dramatic music playing]
[Jeremiah] It didn't work.
Do you have the Flame or not?
If you open this door, I'll give it to you without a fight.
[Cadogan] All right. Disciple Kelly, the door.
[Kelly] Yes, sir.
Here they come. Stay behind me!
- Go, go! - Go!
Whoa, hey, hey, hey. Good guy, good guy. Good guy. Remember?
- Hey. - Hey.
Raven. Hey.
[Murphy] Don't worry. We have antitoxin for everyone upstairs.
You took down the shield?
Yeah. Sorry about that.
No, it worked. I'll get the power back on.
Hopefully without killing anyone this time.
[suspenseful music playing]
For all mankind.
It's been too long. I can hear the bugs.
[Musgrave] Control, Disciple.
[groaning]
[Sheidheda in Trigedasleng]
[Musgrave] I told you our orders are to guard the Stone and the prisoners.
[Hull] We don't need the prisoners.
[Sheidheda in Trigedasleng]
[Indra in Trigedasleng]
[in English] First, I kill my enemy's enemy.
Then I kill my enemy.
I don't think you should've given him that.
Why?
I remember things.
- Your sketchbook? - [softly] Yeah.
Madi, don't tell anyone that. Okay? Never.
How much longer do we have to stay here?
Once the power's back on, the bugs will kill each other,
and the shield will prevent more from coming in.
Till then, it's not worth the risk.
Hey, finally! Stranger.
It's good to see you, Bellamy.
It's good to see you too.
Well, those are the clothes of a man with a story.
Yeah Bellamy, why don't you tell us a story?
[power humming]
Another time. Not long now, my Shepherd.
[computer] Power restored to all sectors.
And the crowd goes wild.
Seriously?
[computer] Secondary containment cleared.
[suspenseful music playing]
Hatch used to say, "Returning to the scene of the crime
is like a fish that was caught and released, biting at another hook.
Only fools and fish do that," he'd say.
[gasps]
But he's dead now...
because of you.
It doesn't matter what he'd say now, does it?
- Nikki, wait... - I've waited long enough.
You're going to die today, in the same place that he did.
There's poetry in that. Coming full circle and all.
But first, I wanna hear you say what you did.
There it is.
Yeah, cry while you confess your sins.
The Grim Reaper will wait.
I killed him.
I knew radiation was leaking in and I sent them.
Then things got really bad, and I... I locked him in here.
Because I was afraid he was as much of a coward as I am.
He wasn't. He was brave.
I chose to let them all die.
And save myself instead.
It should've been me.
That should have been me.
If it'll bring you peace, do it, Nikki.
- [sobs] Please. - I have a better idea.
You live with what you've done.
[knife clatters]
Raven?
- Hey. Hey. - [sobbing]
It's okay. It's okay.
You're okay.
[tender music playing]
[Sheidheda in Trigedasleng]
[Indra in Trigedasleng]
[Hull] I'm going after the Shepherd!
[Musgrave] You will not. You'll follow my orders.
[Sheidheda in English] Natives are restless. Hurry.
- [Indra in English] I'm going as fast as I can. - For God's sake, before I bleed out please.
Is there a problem over there?
No. No problem.
[Hull] I am his shield and his sword.
Those are my orders.
[in Trigedasleng]
Smart move killing that one.
You got the others on your side.
Now, if only you could get the antitoxin to the Shepherd, then you'd be heroes.
I can take you to the lab where...
[man 1] Indra!
[man 2] Get in your helmet!
[neck snaps]
[suspenseful music playing]
[in Trigedasleng]
[yells]
[Sheidheda]
[Indra's mother in Trigedasleng]
[Sheidheda]
[door opens]
Looks like we missed all the fun.
Indra?
[Sheidheda]
[Indra's mother]
[dramatic music playing]
[in English] I saved your life, Indra.
Surely, that's worth something.
[in English] Yes, it is.
[yells]
I don't need to kill you because you're already dead.
No one treats him.
- Wasn't planning on it. - Me neither.
[in Trigedasleng]
[man 1] Report position.
[man 2] Entering the Great Hall with the Shepherd.
Where the hell is my daughter?
Who the hell is your daughter?
[Bellamy] Indra, hold on.
We didn't know she was missing till today. Nobody did.
We're gonna get everyone back.
Put down the gun.
It's okay, Indra. He's gonna help us.
- Does that mean you have the Flame? - I do.
Now is the time. Tell him.
I believe I can restore the damaged code.
With this.
It's used to repair memory drives, stitching together broken strings of code.
Code that, like the Flame itself, was created by...
Becca Franko.
[suspenseful theme playing]
Show me.
[Josephine] It's okay. You can do it.
If Becca's memories are still in here...
this will find them.
Then we can start the Last War.
[Cadogan] It's working.
I'm so proud of you, baby.
Now volunteer. He needs a Nightblood.
What is it? What's wrong?
We are.
I'm sorry.
Helmets off and weapons down. All of you. Right now!
Antitoxin.
No, Gabriel, you need me.
- Gabriel, please don't... - Gabriel?
Gabriel, we need him to get our friends back.
Your friends.
Echo and Hope too.
Now put down the gun.
- Take him! - [gunshot]
No!
No.
Don't lose faith.
Raven, fire it up. We need to get to our friends.
[Raven] Which planet? Where are they?
It's offline.
Only I know the code.
[Raven] He's telling the truth.
There's one planet we can't get to.
Enter the code and you get to live.
[dramatic music playing]
- [Cadogan] There's your bridge. Go. - You're coming with us.
Now move.
You should have more faith, Clarke.
Not you. You've made your choice.
I really hope this new thing you believe in is worth it.
It is.
Come on. Let's go.
[Clarke] Indra, watch him.
I said I wouldn't lose anyone else.
But I have.
You.
That doesn't matter to you though, does it, Disciple Blake?
So much for together.
Let's go.
I can help if you help me.
My throne.
The book.
[Clarke] Bellamy.
[in Trigedasleng]
[gun cocks]
Clarke, Madi isn't in danger, I'll make sure of that.
[Clarke]
- I am trying to save us all, Clarke... - [in English] I'll kill Cadogan.
Is that what you want?
[in Trigedasleng]
- Get her! [grunts] - Hold, hold!
Clarke, this isn't about Cadogan. It's bigger than any of us.
[in English] Don't make me do this.
You're not gonna shoot me, Clarke.
The Bridge will close. You should go.
[Clarke] Not without that book.
Look at yourself.
What you feel right now...
the need to protect someone you love so badly,
you're willing to kill your closest friend, someone you trust,
who's telling you that the fate of the entire human race is at stake.
All that suffering can end.
Madi's suffering too.
I have no choice but to share this.
[Clarke] I can't let them hurt her.
This is how we do better.
This is the only way.
I'm sorry.
We need to keep this safe for the Shepherd.
Me too.
The Bridge is closing! Get her! [grunts]
[gun clicking]
[dramatic music playing]
[sobbing]
[theme music playing]
