Previously on Z Nation.
So what's your name?
Who the hell are you supposed to be? 5K?
You're with me now.
I'll never be with you.
And yet, here you are.
These injectors are our boosters.
It counters his bite and frees us from Murphy's control.
He's got my medicine! After him!
[growling and munching]
(female voice whispering)
Look what I found.
She should've had more faith.
She didn't deserve you.
Don't say that.
Everyone deserves me.
What do we do now?
You don't have to call me sir.
What we do now is we keep moving forward.
Dr. Merch, she chose her fate.
She chose to be afraid.
But you and I, we will make different choices.
What do you want us to do?
Finish the moat.
Get the power back on.
Now go. I need some me time.
I just wanted to say thank you.
I was gonna end it all.
I mean, why go on without hope?
But then you Thank you.
I'll just go help out with the moat.
You weren't actually afraid, were you?
Not of the zombies anyway. You're too smart for that.
So what was it?
Something go wrong with the vaccine?
Some unexpected side effect?
Ha ha. That's a familiar road, isn't it?
Why couldn't you just finish the vaccine before you decided to check out?
Why do I have to do everything myself?
Dammit, Merch. I'm a savior, not a doctor.
Now what in God's...
What in my name am I supposed to do now? Huh?
If only I knew what was going on in that pretty little head of yours.
Those dense, grey, greasy brains.
Those beautiful, spongy, delicious...

♪ Have mercy, ♪
♪ Oh, have mercy. ♪
Where are you?
Red: No, no. He's not dead.
10K: I tried to get to him.
There were too many.
I don't believe you.
To Z, or not to Z.
Sorry. I couldn't resist.
Alas, poor doctor, I thought I knew you.
I thought you knew me.
A world without fear. Not just for you and me, but for everyone.
We were so close.
And then you stopped.
You saw these people find safety for the first time in years.
You created that original vaccine for a reason.
I was chosen to receive it for a reason.
So why would you stop it?
Why would you stop me from helping them?
No, that's okay.
You don't have to say anything.
I will find the answer.
The truth is out there.
Or is it in there?
[yelling] Get out of here!
He sent you after me.
You're important to him.
What do we have here?
That's not the mark from the vaccine.
You got something different.
You stole the injectors, and you used them.
Where is it?
I don't have it.
I was ambushed.
They took my motorcycle.
Motorcyle you said?
Yeah. And the medicine.
You were traveling east?
So are they. Let's go.
To get the medicine back.
Take you and it back to Murphy.
Fractured love line.
Well that sucks.
Long life line. Hmm.
Well, I guess for the Apocalypse, you made it pretty far.
But you could've gotten further.
You could've had a long full life.
But you chose not to.
A booster shot.
The original vaccine.
This is what you took before you walked into the Zs.
So they could smell you?
So you wouldn't be protected?
So you would die?
No, it doesn't make sense.
Maybe you got the vials mixed up.
The vials mixed up.
Or maybe you were testing the blend vaccine on yourself.
Getting all Jonas Salk and sh1t.
You thought you were making yourself more zombie proof.
So it was an accident. Yeah, that's it. It was an accident.
Or was it?
Not an accident.
You took it on purpose.
More than once.
The original vaccine. That nasty cocktail.
The one that would make me more human if it didn't kill me first.
And you, it made you more human too.
And 10K. It made both of you more human and less me.
So what you're saying is it's worse being me than being dead.
Is that it?
You would rather not exist than be part of my world?!
As if there's something wrong with me!
Is there something wrong with me?
Because if there is, it's because of you.
You did this to me!
All of this!
So answer my question.
Is there something wrong with me, Dr. Merch?
Answer me, you bitch!
How's all this running away working out for you?
Murphy offered you peace and freedom.
But you ran away from that.
You like fear? Is that what it is?
What about pain? You like pain?
Did you know that Murphy has a plan to get the electricity going again?
And running water.
Can you imagine indoor plumbing again?
I know I wouldn't believe it if I hadn't seen it.
But somehow when Murphy says something's gonna happen, it happens.
That's what I'm afraid of.
Yeah, fear. That's what attracts the zombies.
That's how this whole thing got started.
But Murphy's cure, it fixes all of that.
How could you not want to be part of that?
You don't know him like I do.
All I know is that my daughter's still alive.
And me, my wife, my baby girl, for the first time in years, we're actually safe.
You're only saying that because he bit you.
I asked him to.
I begged him to actually.
And it was the best decision I've ever made for my family.
So you traded your freedom for safety.
Do you even remember what you were before he bit you?
Afraid. That's what I was.
But not anymore.
You wanna talk about freedom? That's freedom.
What do you think was in that injector?
My free will.
I don't think so.
That medicine wasn't meant for you.
It's messing with your mind.
It's making you paranoid and afraid.
These days, afraid and dead are the same thing.
That's why Murphy sent me.
To get those injectors back.
So nobody else gets sick in the head like you.
The world without Murphy.
It's just more of this.
An unending slog of fear and misery leading to certain death.
I could put you out of your misery. Give you mercy?
I don't want to be afraid anymore!
Welcome back to sanity, son.
The control of a human.
The power of a Z.
That's me. That's my legacy.
I need to make more booster for me and more vaccine for them to finish the plan.
Bring it to completion.
I have to do it myself. I have to do it myself.
What else is new?
It's low blood sugar.
You better eat something, Alvin. Got to take care of yourself.
People counting on you.
You were close.
I know you were.
10,000 doses in just a few more steps.
Maybe you just add water.
That's not it.
That's not it. No.
What the hell is dsRNA? Or IFNRA2?
How exactly does the pumpkin seed looking thing connect to the PacMan looking T-Cell thing.
And what in the name of all that is holy is cytokine or MAP kineses?
This the guy who robbed you?
I guess. That's the bike.
There's two of them. There's this man, and there's a woman.
There's lots of footprints.
There's too many.
I can't tell if they're zombies or animals.
They took off in about three different directions.
I don't know what we're up against here.
This could be a total sh1t show. We're gonna go back to Murphy.
He'll know what to do. Let's go.
10K, let's go.
It's time to go home!
Red: [whispering] 10K, wake up.
Go back where?
Up there? No way.
You can't leave!
What are you doing?
You can't leave!
Come on! We've got to get out of here!
Can't you hear him?!
They have him! They got him! Who?!
You have to save him. 10K, you have to save him this time.
[screaming and growling]
[screaming and growling]
10K, help me!
5K? You okay?
What are you...
[whispering] What am I doing?
There you are.
Hey, where's 5K?
And that makes my count 1,139. Can I go kill some more?
Thanks for saving me.
You know I'm not real, right?
I don't care.
Murphy: I don't know why I couldn't see it before.
You purify the recombinant proteins of the antigen with chromatography and ultrafiltration.
And then you strengthen the vaccine with an adjuvant that binds to receptors on the macrophages, which kicks Trif into action.
And stimulates the release of type-1 interferons, finally activating the T-cells.
It's so simple.
It's all about the adjuvant.
It's all about the adjuvant.
Hmm, so now, to adjust the adjuvant.
[laughing] Say that three times fast.
You're back. And alone.
What do you mean, dead?
It was a pack of wolves, I think.
Or maybe it was zombies. I don't know.
Whatever it was, it was fast.
It was faster than anything I've ever seen before.
Poor 10K. I saw You saw him die?
No, but Then he's not dead.
But, I found That kid has 10,000 lives.
If you didn't see him die, he's not dead.
He'll be going for Warren.
And then they'll all come after us.
We need to get ready. Gather the others.
Prepare for an attack or a siege or both.
The battle for the future of humanity is about to begin.
And I intend to win it.
