La Brea

You had PTSD.

So I started taking something for it.

This morning I lost my last pill.

Damn it!

Sure about this, Sam?

She's a threat to everyone here,

especially Lilly. -Let me out of here!

Go save them.

-That's not gonna happen. -This is private property

so I hope you have a warrant.

What about my family?

There's another way to save them.

Go back to the beginning, Gavin.

Looks like a sinkhole.

I'm in that place.

I don't think the things I've been seeing are visions.

They're memories.

It's your last warning, Rebecca.

Let him go.

- -Oh, my God.

The boy, you need to find him.

Isiah is Gavin

and he needs your help.

What do you mean Isiah needs my help?

Everything depends on it.

You have to find him.

You have to get him to Topanga.

Hold on.

I'll be right back.

She needs you. Hurry, hurry.

We need to get Sam here right now. She needs a doctor.

-I'll go but what happened? What did Aldridge say?

We need to find Isiah.

Dad, I don't understand.

How could you be from that world?

-I must have come through the sinkhole when I was a kid.

I--I wasn't alone.

You think Ella was with you.

We were found together,

less than a mile from here.

-You've got two seconds to get the hell off my property

or I'm calling the police.

-Ella. -Who are you?

Why have you been following me?

My name is Gavin Harris.

This is my daughter, Izzy.

This is Dr. Sophia Nathan.

We can explain everything.

Please, we need your help.

With what?

I know this is gonna sound crazy,

but somehow,

I think you're the key to saving my family.

No... way.

Hope you're all hungry.

Again with the mushrooms?

-Hey, until they get back from the fort with other options,

this is all we got so

eat up, Mr. Juice Cleanse. -Yeah, very funny.

Hey, guys, you're never gonna believe this

but I just saw a cow in the woods.

Okay.

Cattle, along with Christianity and smallpox,

came here with the Europeans,

specifically the Spanish

in the 16th century.

Okay, what I'm trying to say is that

there were no cows in North America in 10,000 B.C.

-Scott. -Yeah.

Buddy, were you--

Don't make this about the weed.

The cow was there.

-I believe you. -Thank you, Lilly.

Say there was a cow.

Who cares?

Uh, cows make milk. It could help us.

If it wasn't already eaten by a saber tooth.

-You know, you don't really take good news very well.

Has anyone ever told you that?

Levi.

What's going on? Where's Mom?

She's back at the village with Ty.

They're fine but someone else is injured.

Who?

It's a lot to explain.

Where's your dad? I need his help.

Are you sure you're up for this?

Riley, I'm fine.

Dad, you just got off your meds.

You're gonna start going through withdrawal.

Someone's hurt. They need me.

All right.

Then you won't mind if I come along.

Riley.

Consider it on the job training.

After everything that's happened down here,

let's just say I'm... reconsidering med school.

Really?

Yeah.

Also, I'm not taking no for an answer.

We should get going.

We're ready.

I know something's going on.

What aren't you telling me?

You should come back to the village.

You need to talk to your mom.

-Any sign of Silas and Isiah? -No, nothing.

Your people are still out there looking.

Maybe they'll have better luck.

-How's Aldridge? -She's unconscious.

I've done everything I can

but if your doctor doesn't arrive soon,

I don't know if she'll survive.

Eve, are you okay?

Well,

that woman just told me that Isiah grows up

to be my husband so no, not really.

And you believe her?

-Honestly, I don't--I don't know what to believe.

-Silas stabs Aldridge and then takes off with Isiah.

Why would he do that if there wasn't something else going on?

-What more can you tell us about Isiah and Silas?

Where did they come from?

They joined our village a few years ago.

Silas said they fell through another sinkhole.

That the boy's parents didn't survive the fall.

We had no reason not to believe him

so we took them in.

But it seems there's more to him than we knew.

Unbelievable.

Sam, thank God you're here.

-I'm the doctor. Where is she? -This way.

Josh, what are you doing here?

Uncle Levi thought I should come.

He needs to hear what Aldridge told you.

If there's even a chance she's right,

he should know.

Mom, this is insane.

How the hell could that kid be Dad?

I'm just telling you what she told me.

Well obviously, she's wrong.

Hold up. You don't actually believe her, do you?

-I don't know. It's just-- -It's just what?

There's something about him.

His eyes and--and his smile.

-Mom. -Your dad doesn't have

any memories from childhood.

And he was the same age Isiah is now when he was adopted.

And I'm not saying I believe it.

I'm just trying--I'm trying to understand it.

Hey. She had blood in her lungs,

but Sam was able to drain it.

She's going to be okay.

Come on, she's awake.

-Have you found Isiah? -Not yet.

Our people are still searching.

Okay.

All right, so...

when you said Isiah is Gavin--

I understand why you wouldn't believe me

but it's true.

How is it possible?

Gavin was born in this world.

He came to ours through a sinkhole

in Topanga in 1988.

That's where your dad was adopted.

-There's a portal on top of a mountain in Topanga.

It's open right now and it leads to 1988.

You have to get Isiah through it.

I was gonna do it myself until Silas stopped me.

How do you know all of this?

It doesn't matter.

The only thing that does

is finding him and getting him through the light.

It's on the highest peak in the area.

No way.

I don't trust her.

Neither did Gavin and Izzy at first.

-Wait, you were with them? -Yes.

Before I came down here,

we were trying to rescue you.

Are they okay?

For now.

What does that mean, "for now?"

If Isiah doesn't make it to 1988,

you and Gavin will never meet.

Josh and Izzy will never be born.

You don't have much time.

The light is gonna close.

-When? -Tomorrow.

So we're just supposed to send Isiah alone?

He'll be fine.

You already know how it turns out.

Mom, come on, this is crazy.

Josh, you may not believe me now,

but when the light starts to close, you will.

You're gonna begin to get sick.

Izzy will too.

The more it closes, the worse it'll be.

What are you saying?
