Mom!

When we fell through that sinkhole,

we ended up some time around 10,000 B.C.

There is a building with a portal.

It can connect to the future.

Every time that portal's bent to a new time,

it creates a new sinkhole.

We can fix the machine so it won't cause any more sinkholes

and we can still get home.

New sinkholes, they just keep opening up.

We have to stop them.

It's our only way home.

- Hey, guys! - You don't have to do this!

I'm trying to protect everyone.

I gotta stop it.

Every day since we've got here has been a struggle,

and we've certainly faced our share of hardships.

But we've also had our share of blessings.

I'm pregnant.

My entire life I've been fighting

to put my family back together.

We're not giving up.

There is another portal. We may still have a way home.

This is where the coordinates end.

Why are there nothing but dead bodies here?

Hey. It's okay, I'm a friend.

Where are you from? - Here.

How did a military barracks get to 10,000 B.C.?

If you help me find my mother,

I'll tell you everything I know.

This is it.

Amazing.

It's the machine.

Something's wrong.

Look at these dates.

They're all over the place.

Those auroras,

anything could be coming out of them right now.

Run!

Wait! Wait a minute!

Take this and go. - No, no, no, no.

We found each other once. We can do it again.

Eve!

She's gone.

Life's good, isn't it?

Hey.

You get some breakfast?

Heard someone found some hens.

They're making eggs.

Dad, I'm not hungry.

Hey, I... I know this seems hopeless.

But Scott and I, we're gonna fix the laptop.

It was connected to Moore's portal.

Maybe it can show us where your mom went.

Okay, then what do we do?

Hm?

Who cares where Mom is?

All of the auroras are closed, Dad.

There's no way to get to her.

Iz, I'm not gonna give up.

I'm gonna bring your mom back.

You've been saying stuff like that since the beginning,

all of these promises.

Look where we are.

Hey, Iz, Iz, Iz, Iz.

Dad.

I get how you're feeling.

I... I feel the same.

I miss her too.

Maybe we could, uh, work on this together.

C-could be good for us.

I can't do this right now.

Okay, security has to be our top priority now.

We need to light fires

all around the perimeter of the Clearing.

And we need to make that perimeter

as hard to break through as possible.

So you see these, these spikes?

We're gonna do the same thing side-by-side

until we got ourselves a good defensive wall.

Not an easy job, but it's doable.

Dude, we got dinosaurs down here now.

Gavin, didn't you say you and your kids

barely got away from a T. rex?

Yeah, we did, but, uh,

well, thankfully, that was a long way from here.

See? Gavin thinks it's dumb to build a wall.

No, I... I didn't say that.

Listen, no animal likes fire.

And they sure don't like running into spikes.

Look, I know it's not perfect,

but it's better than we got right now.

It's just... I mean, two days ago,

we thought we were all going home.

And now it looks like I'm gonna be taking orders

for the rest of my life from a guy who used to deal heroin.

Easy, Judah.

Let's just calm down.

Lucas is our leader.

He was elected fair and square.

All we can do now is push forward.

Got it? - Okay.

Look, I understand people are frustrated,

and we're scared. I mean, I feel the same way.

But I still think there's reason for hope.

And you're right, Judah. I did use to deal heroin.

Okay? I was no good to anyone.

I hurt people. I didn't care.

But I've changed, and now I have people relying on me.

And I'm not... I'm not just talking about you guys,

and I'm not just talking about Veronica.

Well, soon we're gonna have more people to protect.

I want to make sure our home is safe when they get here.

You're having a baby?

Yeah.

That's great.

Family's everything.

I would have donated a bottle of Malbec.

- Ah. - Congratulations.

Look, all of this to say, hope still exists here, right?

So let's get to work,

build some spikes, yeah?

Here. - Weren't you the one

who just told everyone they need to get to work?

What kind of example are you setting, Mr. Leader Man?

I know. I know.

But trust me, you're gonna want to see this.

You wanted to show me a bag?

Yeah.

Hmm.

No.

It is an extremely comfortable mattress.

Oh.

That's much better.

Right?

It fell through one of the auroras.

Anyway, we can put this in the bus.

- What? - Yeah.

The rest of the group seemed cool with us taking it over.

I think they're, you know, excited

to have a, uh, Clearing baby.

Oh, they are, are they?

Uh-oh.

You're upset I told everyone you're pregnant, huh?

Mm, "upset" might be a strong word.

Well, I'm sorry, I just...

I'm... I'm excited, you know,

to be a dad.

I mean, we had to tell them anyway.

It just kind of slipped out. It w-won't happen again.

I'm sure it won't because I think Judah

pretty much told everyone in 10,000 B.C.

Okay, so you are upset?

I'm... excited to be a mom too.

I'm just nervous. I'm...

I mean, we don't even have any medical equipment

down here and...

You okay?

What's going on?

Oh, that.

You all right?

You feel better?

Well, we might not have medical supplies,

but we got that...

your morning sickness,

every eight hours, like clockwork.

Sam said that is a great way to tell the baby's doing okay.

So my extreme nausea's a virtue?

Okay, well, it's not ideal, but it's... it's something.

I mean, we got a home, a mattress.

And we're gonna put a wall around all of it.

It's gonna be fine.

It's gonna be great.

It is.

Okay. Grab your mattress.

I need a nap.

As you wish, milady.

Hey, Gavin Harris, the man I was looking for.

- Yep. - Hey, why don't you go ahead

to the Clearing while I talk to Gavin.

So what are you doing out here?

Just trying to get this computer to work.

This solar battery's fried.

You didn't find anything to charge it with, did you?

Did I ever.

Ta-da.

A potato?

Okay, you look like you're being serious,

but I don't think you should be.

Okay, a potato can be used as a source of power.

All you need is some zinc, some copper nails,

some wires, and a bit of good luck.

Uh-huh.

And this is something that you have done before?

Okay, look, you're missing the point.

The potato means progress.

You should be more excited about this, because I am.

Hey, hey, not that I don't appreciate it.

I do, and thank you, but you don't need to do this.

Don't you have your own problems to sort out?

I do.

Meeting Petra has totally messed with my head.

I was supposed to have a job interview with her mother,

Maya Schmidt, back in L.A. before the sinkhole opened.

But Petra told me that they're from a military base

that somehow ended up in 10,000 B.C.

And you're certain that Petra has no idea

where this base is?

She doesn't, and she doesn't know where her mother is

or why her mom reached out to me in the first place.

So since I can't figure out any of my problems,

I may as well help you solve yours.

All right, well, thank you. You're a good man.

All right. Let's give this thing a shot...

What the hell was that?

I think it came from the Clearing.

Hey, Petra!

Are you all right?

Veronica?

Veronica, hey, hey, hey. What's going on?

The dinosaurs, they're in the Clearing.

Where's Izzy and Josh?

I don't know. I'm sorry.

Iz!

Get back.

Hey, hey!

You guys okay? - For now.

They're destroying everything.

Should we run?

No. No, no, it's too dangerous.

And we're too exposed. Wait, wait.

Dad, it's gonna collapse.

Now. Go, go now!

Let's go!

You okay?

You sit right down there.

Someone will fix you up, okay?

Gotta say, we're lucky no one died.

Eh, you're right.

But that's where our luck ends.

I mean, the Clearing as we know it, it's gone.

Are the dinosaurs leaving?

It's worse. There's more of them there now.

So whatever anyone grabbed,

that's what we got in terms of food and supplies.

Hey.

I have to go back.

Look, we can find shelter and water in other places.

Nah, what I need, I can't find anywhere else.

I have to get that laptop.

Couple days, we see if our friends have left,

and we can get it then.

Right now, we got frightened, injured people

we got to get safe.

On that front, I talked to Ty.

He said that we can regroup at the Fort.

That's exactly what we need right now.

Agreed.

We got a couple of stragglers we have to grab too.

Josh and Riley were off gathering berries

by the dry creek bed. I can find them.

Hey, I can get my own son, thank you.

All right, we'll grab a group to find our kids.

Why don't you take the rest back to the Fort?

Keep in contact, okay?

Happy to help.

Let's go.

Have you ever been to Finn's Bakery on Third Street?

Nope.

They have this raspberry cobbler thing.

It should be illegal.

It's that good.

I'm gonna make one.

Little side hustle,

I like it.

Maybe set up a little kiosk under the Petersen?

But this is our life now,

and in life, the little things matter.

Raspberry cobbler means more than you think.

What?

You're beautiful.

Well,

I'd hunt a saber-tooth tiger for a mani-pedi,

and I haven't changed my clothes in a week.

You're kind and smart.

You've shown me a better version of myself.

Have you been drinking the fermented corn again?

You help me forget what we're up against down here.

When I'm with you, everything just feels normal.

Those are all the reasons... why I love you.

You know, sorry. I... maybe I...

I love you too.

You do?

Yeah.

Like, a whole lot.

Wait.

Don't move.

There's something behind you.

Hey, that is my pancake.

I... I called dibs on the last one.

Then I get last bacon.

Oh, oh, h-hold on.

Didn't you say you were going vegan?

That was a thought experiment.

I'm okay with all this

as long as you save me some coffee.

Ah-ah, that's mine.

Delicious.

All right, everybody.

Hold up.

Let's take a break.

Uh, there's a... a creek over there.

We can refill our water.

Hey.

You got a little blood on your forehead.

You all right?

Oh, yeah. I fell over in the attack.

I guess I hit my head harder than I thought.

Let me see.

You can't fool around with head injuries.

Why didn't you say anything?

Because these people put me in charge,

and that's when they needed me most.

And honestly, I didn't want to worry Veronica.

Ah.

I get it.

You want to be her rock.

That's not always the best move.

It-it's better than being a burden.

Trust me, my dad was barely there for me,

put all the responsibility on my mom.

And, dude, look how that turned out.

Right? I made a promise to myself.

I'm not gonna be like him.

Whatever Veronica wants, needs,

I'm gonna give it to her.

Okay, that's admirable,

but it might not be the whole picture.

What does that mean?

Listen, being a parent, it's a beautiful thing.

I mean, I love my kids more than anything in the world.

But it's hard work.

And you can't do it by yourself.

You need a partner,

someone you can be open and honest with.

You can tell me to shut up any time.

Nah, you're fine.

Okay, well, once I get Veronica settled into the Fort,

I'm gonna work on that.

There you go.

Help!

Help! - Was that Josh?

Riley.

Riley!

What happened?

We were... we were attacked by...

by a raptor.

I-I tried to stop the bleeding the best I could.

Riley.

Sam, is there anything we can do?

There's nothing.

She's sutured and bandaged.

All we can do now is pray that an infection doesn't set in.

Hey, look, I can watch over her if you need a minute.

That's okay.

I'd rather be alone with my daughter if you don't mind.

I'm gonna make sure everyone from the Clearing

has a warm meal and a place to lay their head.

- Will you thank Paara for me? - Yeah, of course,

when she returns.

She and Silas left this morning to shore up alliances

with the neighboring villages.

A lot to discuss, given all the new threats down here.

I'll, uh... I'll catch up with you soon.

Yep.

Riley's unconscious still, but she's stable.

Is she gonna make it?

All I know for sure is, she's a fighter.

Maybe you should get that wound cleaned up.

No, it's fine.

I... I just got a couple scratches.

But... but Riley...

Hey, Josh, it's not your fault, okay?

You did everything you could.

It wasn't enough.

Doesn't matter.

All that does is I...

I-I couldn't save her.

J-Josh, hey.

Dad, I've got him.

Okay.

Hey.

I know things look pretty bleak right now.

I hope this can help.

You went back?

I hope you find what you're looking for.

And this is why you pay attention in science class.

Because if you don't,

you wind up eating your best source of electricity.

Okay, tough crowd.

You all right?

Do we have to turn the computer on?

Well, yeah. If we want to find Eve,

the computer's kind of key.

Is there a problem?

What if it signals them?

Signals who?

I didn't tell you this before, but...

me and my mom didn't just leave that base.

We ran away.

You did?

Why?

Because my mother said there were bad people,

and they wanted something from her.

What did they want?

I have no idea.

She told me it was safer if I didn't know.

Petra, why didn't you tell me any of this before?

I was afraid you wouldn't help me.

Hey.

I promise that no one is gonna make you go

anywhere you don't want to.

And this thing is not gonna bring

any of those bad people here, all right?

Hell yeah.

You did it.

Okay, Scott, how long does it take to power up?

Don't know.

Well, apparently, not that long.

Whoa.

What's that mean?

Well, I'm no computer engineer,

but I think it means that there's

an electromagnetic transmitter broadcasting a linear signal

to this machine's receiver.

Uh, this computer here is talking to something out there.

There's someone else on the line?

Uh, I mean, technically, yes.

Hello.

Gavin Harris.

Who are you?

Is this some kind of a joke?

How do you know my wife?

Where the hell is she?

How do I get my wife back?

Come on, answer me. Come on.

Sierra? Who's that?

Sierra.

- What happened? - Hey, where'd it go?

Scott? Scott. - Uh, here.

Can't you get it back?

Um...

No. I can't.

It's disconnected.

Gavin, you okay?

Dad.

Hey.

Hey.

You're awake.

Well, I had a pretty good doctor patching me up.

I don't know what's gonna happen,

so I'm gonna say a few things while I still can.

No, no.

You just need the rest.

You can tell me when you're better.

Dad.

I have internal and external wounds.

My heart rate's fluctuating.

Fever's high.

The edges of my vision are blurry.

I mean... I think it's an infection.

No, no, no.

Dad.

I don't have much time.

Riley, just rest.

It's funny, when that word "Sierra" came on the screen,

I thought you might have recognized it.

I have no idea where it comes from or why, I just...

I know it means something to me.

This might sound strange, but I feel like, uh,

it's connected to my family somehow,

to a breakfast we had together.

I bet it's less strange than you think.

Our minds often hold answers

whose origins are at first inexplicable,

until they're not.

So tell me more.

Uh...

A few days ago, I was looking at the laptop with Scott.

All of a sudden, I had a flash of this memory.

Haven't been able to stop thinking about it.

It's just a morning with Eve, the kids, Levi.

Same day like any other,

simple, we were happy.

I don't know what the connection is

to the word "Sierra," but I feel like...

I feel like it's related somehow.

You know, in my practice,

when people needed to recover repressed memories,

I'd often suggest they find something or someone

connected to that memory.

Yeah. Like my kids?

I don't think Josh or Izzy are in the best headspace

to help.

Right.

I was thinking more about a friend.

You want me to bring it to Levi?

I do.

Look, I know his actions affected all of us...

- That's an understatement, Ty. - But when it comes

to helping your wife,

he's your best shot.

I believe he's still your friend.

Guys!

I come bearing good news.

So I was trying to get that chat screen back online,

but I think I found something even cooler.

Whoever you were talking to,

they were transmitting a signal.

Now, the origin of that signal is nearby.

I think it's within a few miles.

How would you know that?

Uh, pretty simple. There was a map on the laptop,

had a blinking dot.

I don't know what we're gonna find.

Whatever it is might help us get back to Eve.

Thank you, Scott.

Hey.

What happened to Riley...

It's so awful.

Yeah, I know.

Uh, I checked in on Sam, and, uh,

I think he's just in shock.

Makes you think about how fragile life is.

Look, I know things are hard and scary,

but we're gonna be okay.

Really, we're gonna build a home here for... for us,

for, um... all of us.

Are you okay?

Yeah, I'm fine. I'm fine.

- You don't look good. You should sit down.

- I'm good, I'm good. I think I just...

I need to eat something.

You know, I thought I saw Judah picking some fruit

for a smoothie, so I get some food,

so I might, um...

Lucas!

Lucas?

How is she?

Not good.

I've been trained to handle a lot of things,

but nothing prepares you for this.

You need to know,

wh-when that thing attacked us,

she fought back.

Riley fought back with everything she had.

You know... you know, the truth is...

she saved my life.

And if you could, you'd trade places with her.

In a second.

That's not what she'd want, Josh.

I... I just...

I just don't know what to do.

Sam? Sam!

Lucas passed out. Can you help him?

All right, keep your eyes peeled.

If the bearings in that computer were right,

I think the signal should be in this area.

What exactly are we looking for?

Uh, that's the million-dollar question.

Something that can relay a signal,

a... a radio tower, something metal.

I think we'll know it when we see it.

I don't see anything.

No, no, it's gotta be in this area.

Let's split up, keep looking.

All right?

Levi?

There's something we need to talk about.

Yeah, sure.

- Something from our past... look, I gotta be honest.

It's not easy for me to talk about with you.

I understand. Gavin, I'm here to help,

so tell me how I can.

Look, I keep having this one memory.

It was at a breakfast.

Eve was making these smiley face pancakes.

You were there. Might be hard for you to remember.

It's not.

It wasn't just a random breakfast.

It was Izzy's birthday.

- It was? - I still remember

exactly what I got her.

Hey, that's my pancake.

I-I called dibs on the last one.

Then I get last bacon.

Hold on, didn't you say you were going vegan?

That was a thought experiment.

I'm okay with all this

as long as you guys saved me some coffee.

Happy birthday, kiddo.

That's so strange. Wh-why can't I remember that?

Your visions, Gavin. That was the year they started.

Changed everything.

Your mind was completely scrambled.

Yeah, everything was a blur.

My drinking didn't exactly help that.

Okay.

Anything else you remember from that day... anything?

Yeah, yeah, um,

at some point, you went outside.

I figured you were just drinking,

but when you came back, you were really upset.

Hello, Gavin.

It's my daughter's birthday.

You can't be here, Sierra.

I-I know it's not ideal,

but this is the safest way for us to talk.

There's nothing for us to talk about.

I'm done with the program.

Unfortunately, we're not done with you.

Hey, hey, hey, hey.

This doesn't work for me, okay?

You come here, you know where I live,

you know who my family is.

I don't know a damn thing about you.

I don't even know your real name.

No, I'm done here.

I'm going back to my daughter's party.

You're right.

You deserve to know who I am.

My name... my real name is Maya.

Maya Schmidt.

Sierra.

It's not a name. It's a military call sign

for a woman I used to work for.

What are you talking about?

Levi, I remember, okay?

I spoke to her that day, outside Izzy's birthday.

Her real name, it's Maya Schmidt.

That's Petra's mom, who's down here in 10,000 B.C.

Right. We have to find Petra now.

Petra?

Petra!

Petra!

There you are.

I need you to come with me now.

Gavin needs to ask some questions about your mom.

Are you all right?

Petra?

Petra!

Ah!

What the hell?

Levi!

Petra! - Hey.

What's happening?

Levi and I were looking for Petra,

but I can't find either of them.

Levi!

Oh, no.

It's Petra's locket.

Where the hell did that Huey come from?

It must be from the base.

Petra was worried that they'd come after her.

Okay. We have to go after them.

Let's go. - Wait.

There might be something you want to see first.

Here.

I think this is where the signal was coming from.

It's an aurora.

But why is it two different colors?

Because it goes to two different places.

My mother told me about dual auroras.

So it's possible one of these leads to Eve.

Yeah, we just don't know which one does.

Dad!

Hold on. What are you all doing here?

Sam, what's going on?

Scott radioed back what you guys found.

We gotta get her through the aurora,

maybe get her to a hospital.

Okay, Josh, I appreciate you want to help her,

but it's too dangerous, okay?

If... if Sam wants to take that risk, it's his choice.

Look, there's something else you all need to know.

What do you mean?

Look, Petra's mother, I...

I used to work with her.

She's the key to getting your mom back,

but she's here in 10,000 B.C., so we need to stay.

You... you want us to stay here?

No way. I... I can't.

Josh, you're not going through!

You need to stay. We do this together.

Uh, guys, it looks like the aurora's about to go away.

Dad, I have to go.

I can't lose her too.

- No! No! - Josh!

Riley!

Dad, what do we do?

Ty!

He's gone.

They're all gone.

How you feeling?

Like I should be the one taking care of you.

You know, you don't always have to be the protector.

You just have to be honest with me.

Sam said the same thing.

Hm.

So why didn't you listen?

Because I'm stubborn.

And honestly, I don't want to be like my...

my dad.

You're different. You want to be a good parent.

Of course I do.

So then you're gonna be great,

as long as you don't get in your own way.

So you want honesty?

Yeah.

All right, well...

I'm really excited to do this.

But I'm also terrified.

Why does that make you happy?

Because I'm terrified too.

I... I want to be in this together with you.

I don't want us pretending like everything's fine if it's not.

If something sucks, then we'll say it sucks.

And if it's great, then we can say it's great.

Okay?

Yeah.

Okay.

You want some more honesty?

Mm-hmm.

Every time you throw up,

it kind of makes me want to throw up too.

I'm just being honest.

Would now be a bad time to tell you

that I just threw up before I came in here?

Mm.

I mean, I guess I'm just gonna

have to kiss you anyway, so...

Mm, papaya.

Jesus, man.

What are you doing in the middle of the road?

I don't know.

Sorry.

Are we in Los Angeles?

What kind of question's that? Of course we are.

Can you tell me what date it is?

- You all right, friend? - Please, the day and the year.

It's September 12, 2021.

That's a few weeks before the sinkhole.

Unbelievable.
