Previously on "The 100"...
Clarke, on radio: Carl Emerson,
I have a message for your leader.
I will not stop until my people are free.
If you don't let them go, I will irradiate level 5.
We all have pain. Some of it is physical.
It'll make it go away.
Time to get back to work, raven.
The city of light is real.
And that's supposed to take me to the city of light?
On your feet.
The grounders out there will attack this camp.
We wait, we die.
This land is ours now.
Resist, and you will be greeted by death.
Here we stand on the brink
of another war, a war you could stop.
Blood must not have blood.
Mm...Mm...
Hey, hey, it's OK. You're OK.
What were you dreaming about?
Commanders before me.
They speak to me in my sleep.
I saw their deaths--
at war, at the hands of an assassin.
It was just a nightmare.
No. No. It's a warning.
They think I'm betraying their legacy.
Jus drein just daun has always,
always been the way of our people.
Listen to me.
A cease fire is not a betrayal.
What you did on that battlefield
stopped a war.
Your legacy will be peace.
Oh, um, that's, um--
it's not finished yet.
Enter.
Pardon me, Heda.
I didn't realize you were busy.
Are you going to tell me what's in the box, or not?
Forgive me.
This is a gift from king roan of Azgeda
for Wanheda.
The messenger said this is both proof
of Azgeda's loyalty to the coalition
and an answer to a yet-unanswered question.
May I?
Open it.
Emerson.
Stop him! Get him out of here!
Put him in a cage now!
I'm fine.
We done here?
10-meter draw, and I'm good.
Pike's detail is still at it--
soil and water samples.
Any idea what they're up to?
No, but considering how heavily they're armed,
I don't think they want anyone to find out.
- Crap. - What?
There's a grounder kid. Hang on.
Hello there.
Don't be scared.
We can't let him go.
He'll tell his people he saw us.
Octavia, please respond.
Hannah.
Fan out. With me.
Octavia, you there?
Huh!
They're going after the kid.
I'm trying to cut them off.
Split up.
Uh!
Shh shh shh shh shh.
We lost him.
Double back towards the river.
He can't have gotten far.
Mm.
Hey, hey...
You're welcome. Ah...
- Kane. - I'm here. You OK?
You need to find out what pike is up to
right now.
Whatever it is, they were willing
to kill a kid to keep it quiet.
We're on it. You stay safe.
How about now? Anything?
Nope. All good. Pain's gone.
Hmm, your leg's--
still doesn't work. I know.
I just don't hurt anymore.
Hey, hold on.
Pupils aren't dilated.
Jaha gave me the key to the city of light,
Abby, not drugs.
Yeah. Let's see what the blood tests say.
Thought you'd be happy for me.
I am.
It's just unusual for pain to subside this quickly.
Uh, so am I all clear?
Apparently.
Let Sinclair know that I said
it was OK for you to go back to work,
but you're benched again if I find
anything abnormal in those tests.
You won't. Thanks, doc.
You step aside in case someone answers.
I told you, no one's home.
What?
Bet you didn't think we'd be
breaking the law together when
this isn't a game, Nate.
If we don't find out what pike's up to,
more people will die.
Then let's not get caught.
Chancellor pike, good to see you.
Hey, you put it somewhere smart, out of sight.
I'll buy you some time.
There you are.
We need to talk about these things Jaha's distributing.
No, we don't. That's Abby's department.
I have much more immediate concerns.
Like the imprisoned grounders?
Interned for their safety as well as ours.
They came in for our help.
If we're not gonna give it to them,
They're a liability.
Let them go, they'll tell their people
what they know about us-- our defenses and capabilities.
We're talking about Lincoln here.
No. We're talking about the enemy.
Not all grounders are the enemy.
Kane, we've been through this, all right?
The election decided it.
Public opinion is a funny thing, Charles.
My job is to keep us safe, not to be liked.
Then keep up the good work.
They seem pretty happy.
Yeah. They sure do.
A lot more of them today, too.
I know you're tempted,
but let me figure out what it is first, OK?
OK. Let's get this meeting started.
Welcome farm station's own Monty green
and factory girl Zoe Monroe
as we begin our next crucial phase--
expansion and salvation, and this will lead the way.
Dirt?
Soil--fertile, arable soil,
vastly more rich than anything we've found since landing.
We'll clear the trees and plant within the month.
We start with soybeans and corn.
They grow the fastest.
What's wrong, Monty? Don't like corn?
I've never had corn, actually.
Is this where we're going?
That's right.
There's a village here.
What about the people who live there?
Sector 4. We talked about this.
The people there are not a threat.
We need that land.
With the loss of mount weather's resources,
Arkadia will be starving in less than a year.
With all due respect, sir,
you still haven't answered Monty's question.
You know the answer.
Every field must be cleared of stones
before it's tilled.
We were spotted by a child,
so they'll be expecting us,
but they lost their fighters when we took out the army.
We don't expect resistance.
They're grounders. They'll resist.
Even if they don't,
the commander's message was clear.
Blood must not have blood.
That doesn't mean we can start taking--
what would you prefer,
die fighting for your home
or starve to death?
Will you do what needs to be done
for your people to survive, or not?
We'll do what needs to be done.
You're letting her cloud your judgment at a time--
I thought you were supposed to be loyal.
I am, but you are too personally in--
here she is.
You wanted to see me, commander?
Yes.
I need to discuss the fate of the last Mountain man.
I believe he deserves death.
She can speak for herself, Titus.
Titus is right.
You see?
It is human nature to need vengeance.
Only once satiated can there be peace.
- That is our way. - That was our way.
Clarke...
So blood must not have blood applies
only when it is my people who bleed.
That was about stopping a war.
This is about finishing one.
I'm sorry, but if you want my advice,
I agree with Titus.
He deserves to die for what he did.
I'm not looking for advice. I'm looking for a decision.
He was gifted to you.
Crime he stands charged with
is against your people.
So what will it be, then, Clarke...
Banishment from our lands forever
or death by 49 cuts from your hand?
You have till sundown to decide.
Oh, finally. Where's my horse?
Outside. Nice to see you, too.
Octavia, wait a second.
You actually think that a bunch of grounders
are gonna give up their homes because you asked them to?
If it's that or be wiped out, maybe.
OK. Then what if they don't leave?
Then we're leading our people into an ambush.
Maybe if you just talk to your brother--
my brother is on the wrong side.
So, what, then, we don't even try?
What do you think happens
when Lexa finds out that Skaikru
massacred another grounder village?
War, more dead friends.
Stop the attack, stop a war.
Feeling better?
Better? I feel incredible.
Thank you, both of you.
Thanks you, raven.
More are joining the city of light
because of you.
Anything I could do to help.
What?
Now that you're back on the engineering core--
uh, thanks to Alie--
we'd like you to do a job for us.
Name it.
I've been looking for something for a long time,
searching for it in scavenged technology.
It's one of the reasons we came to Arkadia first.
I believe that version two of my code
is somewhere in the computer system of the ark.
Why did there need to be a version two?
Was there something wrong with you?
Oh, nothing's wrong with her.
No offense.
I'm just saying, programmers
and engineers generally don't go
to a version two unless there is--
raven--
of course.
Of course I'll help you,
but I got to say, I'm fairly certain
if there was an AI on the ark,
I would know.
It will likely be a dormant program,
that or an unfinished one.
If you can gain me access to the mainframe,
I can search for and download
any residual code.
Sounds like a plan, red.
See you on the other side.
Why would you not tell her the truth about me?
John Murphy knew the truth,
and we lost him, remember?
John Murphy never saw the city of light.
Call it an abundance of caution, then.
We are, after all, asking her to find
an upgrade for a computer program
that ended the world.
That's a lot of firepower.
Let's hope we don't need it.
What's the mission?
Planning for our future.
You know, that looks a lot like our past.
We are building a life here,
now trying to make peace with a people
who only understand war.
Damn right.
Hannah, you just got your son back.
Don't send him out there to die.
No one's dying today.
Now let's move out.
Hey, where the hell have you been?
Oh, I lost the damn horse.
Actually, the horse lost me, but--
I'm glad you're OK.
I wish you didn't have to go with them.
Today, Bryan.
Duty calls.
Yeah. Hey, be careful, please.
All right.
AI nou na bash yo op.
Liar. I've seen your face.
You were at the battle of the Mountain.
Your guns killed our brothers and sisters,
warriors sent by the commander
to keep you safe.
I'm sorry for your loss,
but I'm here to warn you that the soldiers
who did that are coming here now.
They want your land, and they will kill
all of you to get it.
You need to leave this place right now.
Are you threatening us?
Uh! Ah!
Rrgh!
You're the one who saved Gavriel?
Don't leave.
Couldn't have said something before I got kicked in the face?
Chronic pain just doesn't go away overnight.
The data says it does.
Elevated levels of serotonin and dopamine
in raven's blood are consistent
with her claims, and since it's
within normal limits, I'd say
it's not drug-induced.
You look disappointed.
No. Surprised.
We've all been through so much
that it's hard to recognize hope,
even when it's right in front of us.
Jackson, can you go check
on the grounder patients in lockup?
Report back to me, OK?
Octavia should be at the village by now,
but if she can't convince them to evacuate--
you have done everything you can.
No.
No, I haven't. I let this happen.
I demanded an election...
And now we have chancellor pike.
We're on the brink of a war we can't win,
and all I can do to stop it
is send kids into harm's way.
Hey, in case you haven't noticed,
they're not kids anymore.
With Clarke gone, Bellamy's the key.
I've been trying to reach him,
but pike's influence is strong,
and he really believes he's doing
the right thing.
Everybody always does.
What was that?
Let's call it hope.
You can pet him if you want.
Gavriel...
Go on.
His parents were warriors,
both killed by Skaikru guns.
You decided to leave.
As you say, we're no match for Skaikru.
What you're doing is as brave as going to battle, Semet.
Uh! Agh! Ah!
Ah...Ah...
What is this?
You think you know us? You know nothing, girl.
Rragh!
All set. We just got to patch you in.
Can I ask you a question?
Why would the second AI be in space?
My creator thought she needed
a more secure work environment.
So did you go, too?
No. I was the reason
she wanted a more secure environment.
She's in.
Who's in?
Jasper, you don't have access to be down here.
Like that's ever stopped me.
Is that Jaha's backpack?
What do you want, Jasper?
Came to apologize.
Might have stolen Finn's ashes,
spread them at the Dropship.
You're not... Pissed?
I'm not pissed.
OK. What are you on,
and how do I get some?
Simple.
I just decided I'd suffered long enough.
So have you, Jasper.
If you're ready, Jaha has the key.
Give us a minute.
Carl Emerson,
mount weather security detail.
I've heard what they call you now--
Wanheda, commander of death.
I should've known it was you
who told them how to destroy the Mountain.
I didn't destroy mount weather.
You did.
381 people--
182 men,
173 women,
26 children.
Two of them were mine.
Your president gave us no choice.
Raagh! Guh!
What's the matter,
you don't like to be faced with your demons?
If you want mercy,
you're gonna have to ask me for it.
Ha ha ha!
I don't want mercy.
I want revenge.
I want you to suffer
the same way that I've suffered.
You can kill me, Clarke.
You can never escape what you did.
My pain ends today! Yours has just begun!
Titus, what are you doing in my room?
You spend so much time talking about peace,
I think it's time we made peace
with each other, don't you?
All right.
I appreciate the predicament you're in, Clarke. I do.
After convincing Lexa not to avenge the massacre
of our army, it must be hard for you
to choose to take your own revenge.
Perhaps now you realize how difficult
this new policy will be for our people to accept.
This has nothing to do with what happened
to your army.
Emerson is guilty.
Wiping out my people for the crimes of a few
is not justice.
Did you not wipe out his people
for what a few of them did to yours?
You're a leader, Clarke. Lexa listens to you.
Help me to protect her.
Blood must not have blood is folly.
Our people will not accept it, and I fear--
I fear it will get her killed.
I can't help you do something
that leads to war against my people.
Then we're at an impasse.
Does it hurt?
He's ready.
Takes away pain. It doesn't cause it.
What if--what if you don't have physical pain,
and what if it's more-- it's more in your head?
Pain is pain.
Your scars run deep, Jasper.
You only get scars once you've healed.
I'll see you on the other side.
Am I interrupting?
Not at all. Please join us.
May I?
You seem to be working miracles with these.
What is it?
And I don't want to hear that it's a key.
Give me the science.
It's all right.
Tell her.
It's a silicon-based device.
Once ingested, the filaments reconstitute
in the brain stem
and interrupt pain receptors,
inhibiting certain neural pathways
from firing.
Should've stuck with key.
Ha ha!
Would you mind if I run some trials on it?
I just want to make sure that there aren't any side effects.
Would you have given it to Wells without testing it first?
Wells?
Your son.
Yes.
Yes. Of course.
Jasper, I need a minute, please.
Could I have that back?
Now, please.
I'm shutting you down.
That's not necessary.
Please, Abby, it's been so long
since I've thought of my son.
Huh. I'm sorry.
I'm not gonna let you give this to anyone else
until I get a chance to look at it.
I am only trying to help eliminate pain,
same as you.
Whatever it is,
it's eliminating more than just pain.
We cannot let her stop us.
Don't worry, Thelonious.
I'll keep an eye on her.
Mm...
No.
Mm!
I don't hear anything.
Maybe no one's home.
Hello? Anyone here?
Maybe they saw our lights and left.
Mm...Uh!
- Uh! - Yah!
Contact, two o'clock.
Bellamy! Get them out of there!
It's a trap!
- Fire! - Incoming! Take cover!
The smoke is poison!
Fall back. Fall back!
Stay away from the smoke. Get back to the rover.
Monty! Help!
Let me go!
Please help me!
I have to save her.
- Monroe! - Monty!
Stand down! Fall back!
Hannah, come on!
Come on!
Monroe! Monroe!
Monroe!
Uh!
Monty!
Monty, come on.
We got to get her away from the smoke.
How the hell did they know?
Monroe?
- Monroe. - No.
Your sister did this.
How the hell did she know?
We have traitors in our camp.
Wanheda...
Vengeance is yours.
No.
I don't know if your death would bring me peace.
I just know I don't deserve it.
This man must die.
If Skaikru will not take his life, then Heda will.
Heda will speak for herself. Enough, Titus.
What the hell is this?
I wouldn't be killing you for what you've done.
I'd be killing you for what I've done.
Wanheda knows this.
Her actions show us a promise for a new future,
a world in which violence does not always answer violence,
a world in which our children can flourish
without the shadow of death.
This prisoner is banished from my land.
He will live, but he will live
with the ghosts of those he has lost,
haunted until the end of his days
by the knowledge that he
is the last of his kind.
May you live forever.
You wanted to see me, sir?
- How you holding up? - I've been better.
Yeah. We all have.
We need to talk about your sister.
Two of our people died today because of her,
not to mention the ash-poisoned soil,
making the land useless.
The grounders did that. Octavia tried to warn them.
Yes, after she warned them.
Someone in this camp is giving her information.
I need to know who.
We both know who.
Kane.
We have no proof.
We need to find me some.
Yes, sir.
You're dismissed.
Please listen to me, OK?
I don't know anything more about Clarke, all right?
Listen. I don't know anything.
Forget about Clarke.
Tell me about this.
We have some willing converts, but no keys.
That's gonna be a problem.
One problem at a time.
There's no trace of Alie's code
or anything like it on the ark.
You were sure.
I remain certain that Becca went into space.
Unfortunately, it appears that she wasn't
on any of the 12 stations
that made up the ark.
I'm sorry.
I know how important it is to you to find that AI.
13.
13?
The ark was made up of 12 stations--that's true--
but there were supposed to be 13.
I didn't find that on any of the data.
That's because it was scrubbed.
Blowing a space station out of the sky
to get others to join isn't exactly
an inspirational unity day story.
No. Hold on. Hold on.
Wait, wait. Just listen to me, OK? Listen.
Aagh! Aah!
Tell me more.
I wish I could.
All I know is that it happened...
- Yah! - Ah!
Yaah!
That it was called Polaris.
Agh! Aah!
