In 1988, there's a sinkhole in the Santa Monica Bay.
It's opening right now.
We're gonna go back to 10,000 B.C.
and upload the virus.
And destroy the portal for good.
We agreed. If I threw the fight,
I'd give you the cure, and you'd let me go.
You and everyone you know will pay for this.
I had a vision. It was of your mom
surrounded by all these flowers.
I think she was dead.
Mom dies in 10,000 B.C.
I'm on the verge of stabilizing the portal.
We can get her home.
Stop the upload
and save your wife.
I did what you asked.
Now it's your turn.
Tell me your plan.
Gavin, I am going to tell you everything.
But first, I need you just to sit down and relax.
No, I don't want to relax.
I want answers.
The virus your mother designed
severely damaged the machine.
So step one, my team has to repair what was broken.
Okay. And then?
Then we fix it
so it can finally be used safely.
What's this?
Proof the solution exists.
I've been searching for years for answers.
I believe one scientist has discovered them.
Okay, great.
I want to talk to them now. - So do I.
But Dr. Harold Moore went missing a year ago.
But I believe he's still here in 10,000 B.C.,
and you just may be able to find him.
If you can't find him
with all of your resources, how can I?
Dr. Moore was a close friend of your mother's.
If you were to ask Caroline for help,
I'm sure she would listen.
No. She dedicated years of her life
to destroying your project.
Somehow, I don't think she will.
Caroline used to care about this work.
And deep down, I know she still does.
We can save your wife, and we can do it together.
Apparently, you have a visitor.
- Mom! - Hey.
Hey, I was so worried about you.
Are you okay? - Yeah, we're fine.
Fine? How can you be fine?
Why didn't the virus upload?
Because I stopped it.
Dad's got a lot to tell you.
Okay, when we came back here,
you asked me if I'd had a vision.
The truth is, I did.
Okay, look, there's no easy way to say it, okay?
But you-- you were in my arms, um...
But you were dead.
Okay.
What does that have to do with stopping the virus?
I did it because we need to keep the portal open,
because we need to get you out of this place.
In my vision, your death happens here in 10,000 B.C.
He--he saw these flowers falling around you,
but they only grow here in this time.
I--
From the looks of it,
I see that Gavin has broken the news.
I realize this is confusing.
But I am here to help.
I can save your life.
Eve, hey.
Just hear him out.
I understand why you're wary of me,
but I do care.
I'm the reason you got your son back,
and I asked for nothing in return.
Isn't that worth giving me the benefit of the doubt?
I really want to trust you,
but every fiber in my being is telling me not to.
We need to get back to Josh.
Son.
She'll come around.
Eve.
Hey, hey.
I understand how you feel about James.
Okay, I feel the same.
- So do I. - But if there's even
a chance to save your life,
why won't you consider it?
Hey!
Josh.
You're back.
- Hey. - Hey.
You okay? - Yeah.
We were so worried about you.
What happened?
Ah, I twisted my ankle.
It slowed me down, but I'm all right.
Yeah, next time try to keep up.
- Didn't even ask us, Sam. - Went behind our back.
Should have had a say about--
The right to make that decision.
What's that all about?
I may have had something to do with that.
Sort of told 'em what you guys were up to.
Caroline's plan to destroy the machine, the virus,
trapping everyone down here forever.
Josh, why would you do that?
It was raining fish, Izzy.
People were kind of curious what was going on.
Eve! Gavin!
You're all right.
Thank God.
What about you?
Those people seem pretty angry.
Well, apparently people get upset when they find out
you're trying to take away their shot at getting home.
You know it's more complicated than that.
I know. But like any society,
some people see it one way, some see it another.
So what happened?
We thought James caught you, or worse.
Gavin had a chance to shut it down,
but he didn't.
James has a way to fix the machine.
So it won't cause any more sinkholes
and we can still get home.
And you believe him?
I don't know.
But if there's a chance he's right,
then we have to do something.
Yeah.
I went to a dark place yesterday.
I was ready to do anything to keep that portal open.
So I gotta admit, this is welcome news.
Sam, to be clear, the virus damaged the machine.
There's no guarantee that my father can fix it.
Help! Help!
That's Riley.
Stay with the kids.
I'll be right back.
Riley, are you okay?
I'm fine.
It's Wyatt.
He's gone.
What the hell happened to him?
Was it an animal?
Looks like a knife wound.
Wyatt was murdered.
I can't believe this.
Who would murder Wyatt?
There's a symbol in the dirt.
Anyone recognize it?
Nope.
Never seen it before.
Wyatt must have drawn that as he was dying.
He was trying to tell us something.
Why not just say who killed him?
Maybe he did, we just can't see it yet.
Whoever did this, we need to find them.
What you need to do is rest.
You shouldn't be on your feet at all.
Sam, I have to help.
All right.
The body still has some warmth to it.
This didn't happen very long ago.
First thing we need to do is look for witnesses.
So you guys take away our only way out of here,
and now you want to start giving orders?
We just want what's best for everyone here.
Well, I'm glad you can decide that for us.
But while you're off playing Ms. Pac-Man in '88,
some of us are trying to make this place livable.
Fine.
I'll interview people.
Honestly, I--
I don't think many of them want to talk to you right now.
We'll handle it.
But somebody should retrace his steps.
He wasn't killed here.
Yeah? How do you know that?
Broken branches,
scuff marks in the dirt.
I mean, obviously, Wyatt stumbled here
from somewhere else.
Both my parents are cops, dude.
Okay, but who would do something like this?
Could have been anyone here.
You think someone from the Clearing killed Wyatt?
How much do we really know each other?
Sure, but there are other suspects to consider, right?
The people from the building, the Exiles.
Agreed.
Until we know more,
we need to consider everyone a potential suspect.
Hey. Eve, hey.
Where are you going?
I'm organizing a patrol around the Clearing.
We need to secure the area.
Okay, you don't need to do that.
My vision, we--we can stop it.
Help me. Come on.
Gavin, it's a vision.
Nobody even knows if it's real.
And I think your father is using
your fear to manipulate you.
I understand why you don't trust James.
But you can trust Caroline.
If she can find this Dr. Moore, come on,
we can get you home, get everyone here home.
I know you're worried about me,
but you don't know when or where
or if this vision is even gonna happen.
Right now, what we do know is there's a murderer out there.
And I'm really worried about our kids.
Okay, I am too. But I am more worried
about our kids not having a mother.
We need to do everything we can to get you home.
I'm not going with you, Gavin.
So you arrive in the clearing today,
right before Wyatt was killed.
You actually think I'm a suspect?
Honestly, we don't know anything about you--
well, except that you're a time traveler from the future.
And you're a scientist.
And you're Josh's incredibly young grandmother,
which maybe is a lot.
Guys, I can promise you,
my mom had nothing to do with it.
Just dotting the I's and crossing the T's.
You wanna go do that somewhere else?
All right, Scott, come on.
Sorry about them.
They're just on edge.
Yeah. I am too,
and not just because there's a murderer here.
I heard what you did. Izzy told me.
I'm sorry I didn't go through with the plan, okay?
But James has a way to fix the machine.
All that work you've put in to stopping those sinkholes,
you might still get to do that.
You can't believe anything your father says.
Was he lying about Dr. Moore?
Apparently, he's been working on a solution.
He was, but he never solved it.
How do you know?
You left the Lazarus building years ago.
He's had plenty of time to work on it since.
Look.
This--this is Moore's work.
Okay? It's all James has,
and it's part of a larger equation,
but if we can find the rest,
we'll get the answer.
Come on, hey, I--
I know you couldn't be there for me when I was a kid,
but you're here now,
and I need your help.
Okay.
Thank you.
Everybody grab a weapon, a whistle,
and stick to your assigned areas.
And remember, the person we're looking for is very dangerous.
So stay in teams of two.
Damn. My bad.
There's an extra pair of sneakers on the bus.
I'll wait here.
Okay.
Ugh!
Dad needs our help. I'm going with him.
Hey, Mom doesn't think it's a good idea.
And neither do I.
Josh, you didn't meet James.
I did. This doesn't feel right.
Look, I get it.
But Dad says we have to do this.
We have to find a way to save Mom.
Is that what this is about,
or is it because you feel guilty?
What?
Josh, you spent years not believing Dad
about his visions. - Okay.
I know you want to make up for that, I do.
But I don't think this is the way.
Josh, I'm worried.
We worked so hard to get back together,
and this is already breaking us apart.
Nothing's gonna work out if Mom isn't here.
We have to do something to save her.
Are you coming with me or not?
Ty says he's gonna retrace Wyatt's steps.
I'm going with him.
Do what you want.
Judah, the whole Clearing saw you two arguing yesterday.
- Yeah, it got pretty heated. - So?
I saw you arguing with Wyatt too.
It doesn't mean I'd kill him.
We were friends.
But--but maybe I can help you.
Okay, um, the last I saw of Wyatt,
he told me he was heading to the mushroom field to forage.
And were you anywhere near that field?
Come on, man. I didn't do it.
But I got a hunch who did.
the Illuminati.
- Judah. - Okay, fine.
You're not buying the Illuminati.
- No. - Um,
consider the Knights Templar.
Seriously?
Judah, leave.
Man.
15 interviews, and we've learned nothing--
except Judah's still annoying.
I think we need to reconsider what we're doing.
The killer might not be here.
Dude, we still got a bunch more people to talk to.
I know, but there are some scary people out there.
Like those Exiles, they're freaking crazy.
Okay, but Taamet ran away,
and no one's heard from him since.
Why would he be a threat?
You all right? - Me?
- Yeah. - Totally.
Yeah, just a bit hungry,
low blood sugar.
Let me get a snack, and then we can get back to it.
Help.
Help me!
Somebody, help me!
Hey there.
Oh, you're hurt too, huh?
Okay.
I'm gonna get us out of here.
Where are the flares?
There they are.
All right.
Okay.
This is the last place Wyatt went.
Hey, why don't you two take a look down here?
See if you can find any clues.
You've been awfully quiet.
Anything you want to talk about?
No. No, I'm good.
Thank you though.
Actually, I'm not.
It feels like everything down here
is trying to rip my family apart.
Whether it's-- it's a saber tooth tiger
or a family member I didn't even know I had,
it just--
I can't see any way for us to be together.
Take it from a man who's had his fair share
of scrapes since getting here.
Hope can appear when you least expect it.
You'll find it.
Or it'll find you.
Hey, maybe Sam was right.
Maybe you should go back.
Look, I know you're sick.
My mom told me. I'm--I'm really sorry.
It's all right.
Izzy, that building,
they said it's from the year 2076.
Is that right? - Yeah.
Was there a hospital?
An infirmary.
I know what you're asking.
Those people are dangerous.
I would not trust anything in there if I were you.
Right.
Okay.
Look.
It's definitely blood--
and a piece of Wyatt's shirt.
This must be where he was stabbed.
Harold used to come here to think.
He said the view cleared out the cobwebs.
Looking at it now, I couldn't agree more.
So where do we go?
We once explored a cave system nearby.
He said it would make for a good shelter,
but I can't for the life of me
remember where the entrance is.
Okay, well, let's split up.
We track down Dr. Moore, we find his research.
And we'll all go home.
Exactly.
Okay, we'll go this way.
You know, I wanted to say thanks for coming.
It means a lot.
Of course.
But I'm here for my dad too.
He really scared me yesterday.
All my life, he always had a way through.
But now that we're stuck in this place,
he doesn't.
And it's killing him.
Hey, we're gonna get out of here.
Riley! Josh!
Over there. Come on.
Oh, my God.
Yeah.
Is it Dr. Moore?
It is.
Looks like our search is over.
Hang on.
Look at this.
I think that's a key.
Maybe the key is for a hidden lab
or, like, a safe or something.
May--maybe it's in that cave you were telling us about.
We have to keep looking.
Let's go find that cave.
You know, I was a hell of a softball player
in high school.
Told you.
Things are looking up.
If I thread the needle just right,
then maybe somebody'll see us.
Damn it.
Eve's gone missing.
They lost track of her while they were out on patrol.
- You think something happened? - I don't know.
But with everything going on, we can't be too careful.
Yeah, well, I hope you were careful
when you moved that body.
People are upset.
Last they need is to watch
me do a prehistoric autopsy.
You could have destroyed evidence.
I know why you're mad.
The machine's not working now because of what we did.
- Yeah. - Truth is,
I fought against that.
But I realized I didn't want
more families torn apart like mine was.
So we made a tough call.
You want to be a leader?
You'll see it leaves you
with some pretty unpopular decisions.
Now let's focus on what's in front of us
and work together here.
Fine.
You learn anything new?
It's definitely a knife that killed Wyatt.
Looks like a straight edge.
I'd say seven inches long.
Seven inches.
What is it?
Just give me a minute.
Hey, Virgil.
- Hey. - Everything all right?
Yeah. Yeah, yeah.
I was just, uh, you know,
thinking about my wife, Jane.
I used to prepare sea bass like this
in my restaurant every night.
It was her favorite thing.
I didn't realize you were married.
Yeah.
Worst part about this place is being separated from her.
All I can do is just, you know,
remind myself what she always said.
"Work mends the mind."
You, uh--you mind us asking where you were this morning?
Listen, man, I didn't know Wyatt, all right?
I just saw him around the Clearing like everybody else.
- I didn't ask that. - You were going to.
So where were you?
Well, a ton of fish fell from the sky yesterday.
I was in the woods looking for more.
Was anyone with you?
No.
What happened there?
Stampede, man. I...got injured.
I saw you after the stampede.
You were fine.
You accusing me of something here, friend?
Lucas, maybe we should stop.
You're missing a knife.
Seven-inch blade.
I found that roll in the woods.
That one must have came out
when it fell through the sinkhole.
- Oh, yeah? - Yeah.
Or you used it to kill Wyatt.
- What? - Hey.
Get your damn hands off me.
Dude, are you sure about this?
Wait, shouldn't we talk to Sam first?
Go ahead. Tell him we got our guy.
Lucas, where's Virgil?
In the truck.
Scott says you locked him up because he's missing a knife.
I had to voice my concerns.
Yeah, a seven-inch knife,
and he has a cut on his hand, no alibi.
Plus, he is cagey as hell.
- That's not enough. - Sam,
my gut says I am right on this.
You're only halfway there.
What's his motive?
Look, I--I--
I don't know yet.
But why don't we lean on him,
get a confession?
I'm telling you,
he's our guy.
Guys,
you gotta see this.
We think we found the murder weapon.
It has the same symbol on it that Wyatt drew in the mud.
Look.
If I had to guess, this belongs to the Exiles.
You need to let Virgil go.
Sam, Virgil spent time with the Exiles.
He could've easily got the knife there.
You made a mistake.
You accused Virgil with no proof.
And now you need to fix it.
Okay, fine.
Fine, I'll just let Virgil go.
Something else?
I think, uh,
I might know a bit more about who's behind this.
Looks like we found Moore's cave.
Spread out, keep your eyes open.
His research could be anywhere.
Hey. Check it out.
There's stuff back here.
You guys search here.
I'm gonna check it out with Josh.
If his research was here, he would've hidden it.
Caroline, look at this.
Oh, my God.
I think he might have done it.
Okay, here it goes.
I think Taamet's the killer.
Why?
The symbol on the knife,
I've seen it on Taamet's clothes.
When Taamet was at the Fort,
I went to his cell, and I saw it up close.
Why would you go to his cell?
'Cause I'm the one that let Taamet go.
- What? - Lucas was dying.
I didn't know what to do, so I made a deal.
I told Taamet that I'd free him
if he threw the fight against Ty and healed Lucas.
I messed up. I know, I know.
But the worst part is that the last thing Taamet said
before he left was that he'd be back for revenge.
Jesus, Scott.
Why the hell didn't you say something sooner?
I didn't know how. I--
I was ashamed.
But it is Taamet.
It has to be.
All right, but we gotta tell the others.
No, please.
I'll do whatever it takes to make this right,
but just please don't tell them what I did.
I'm sorry.
But you don't get to make any calls on how this goes.
All that matters is stopping Taamet
before he tries to do this again.
Oh!
Ah!
Ugh!
This is what I do.
I think I can--
I think I can just--
just barrel through it.
I think I can put--
put the blinders on and that I can get through it.
And... that's what I did today.
I just pretended like everything was okay,
and now I'm here.
And I'm--and I'm gonna lose everything.
No.
No. No.
I'm not gonna die today.
Hey, look. Look.
You like jerky, huh?
Go get it.
Okay.
I hear you're heading off to find Taamet.
If it's cool, I'd like to come.
It's the least I can do after making this mess.
You didn't make this mess.
Taamet did.
Hey, you know what's the hardest thing
about being a Navy SEAL?
Being shot at while you're carrying someone
through a war zone?
Forgiving yourself.
Sometimes we find ourselves in situations
where there are no good options,
only bad ones.
So you make the best call you can in the moment,
then don't look back.
But Wyatt is dead because of me.
And Lucas is alive because of you.
You did fine.
I should have said that earlier.
I'm sorry.
It's been a tough few days.
So should I gear up then?
Eve still isn't back yet.
What I really need is someone here
in case there's another problem,
someone who knows how to make hard choices.
You know anyone like that?
I think I might.
Mom?
Oh, my God. Oh, my God, Mom!
Are you okay?
- I need to lie down. - Okay.
Let's get her on the bus.
Does this mean we're going home?
These are just rough notes.
They're not finished.
But you think he was on to something, right?
Yeah. I think so.
I'll get Josh and Gavin.
Uh, Riley, wait.
No one can know about this but us.
Why?
If we share this with Gavin,
it'll end up with James.
I promise you it will not end well for anyone.
You want me to keep this a secret
until you know exactly what you're dealing with?
Hey.
There's nothing back there but some old equipment.
You guys have any luck?
No. Sorry.
Okay. We should get back to the clearing.
Hey, how's your mum?
Sam says she'll be okay. She just needs rest.
How about you?
What happened today with my mom made me realize
that the best way to keep my family together
is just to stick by 'em, so that's what I'm gonna do,
no matter how crazy it gets.
Sounds like a smart plan.
Where are you going?
I want to go with Sam to find Taamet.
But I don't think I can.
I can feel myself
getting weaker by the moment.
Look, whatever you're gonna do,
just be careful.
Someone's coming.
I mean no harm.
I'm here to see James.
Sir.
Normally, we don't allow visitors.
But my guards tell me that you are a friend of my son's.
So how can I refuse?
Please, have a seat.
No, I--I know, I know, it's a lot to take in.
I had the same reaction
the first time I stepped into Lazarus.
Glass of wine?
No.
This is very nice, but I didn't come here to drink.
Oh.
What did you come here for?
I was told you have a good hospital.
And unfortunately, I'm in need of one.
I have a brain tumor.
It's terminal.
I am sorry.
Cancer can be cruel and unfair.
Believe me, I know.
But whatever cards you were dealt,
we can reshuffle the deck,
help you play another hand.
You're saying you have a treatment?
A cure, if given the full regimen.
It took doctors until the mid-2060s to discover it,
but they did.
And we have it.
I'm sorry. I--
I've gotten bad news for a very long time.
And this...
it seems too good to be true.
You are wondering if there's a catch.
Is there one?
Only a request.
In my position,
I'm expected to have all the answers.
I still have questions,
and no one to confide in.
Having someone to speak with can be a powerful thing.
During your intake, you told my guards
that you're a psychiatrist.
I am.
Do you think we could arrange a time to chat?
How about now?
Hey.
Just got back.
You okay?
Sam says it's a pretty bad concussion.
But I'm happy to see you.
Yeah, it's, uh--it's like the one in your vision.
Believe me, I thought a few times today
it was gonna come true.
Doesn't mean we're past it.
We have to talk about my vision.
Just because you don't want it to be real,
doesn't mean it isn't.
I know.
And you're right, I was scared.
But I'm not gonna hide from it anymore.
Okay.
We'll deal with it together.
But we have to be on the same page about everything.
That includes your father.
I found Dr. Moore.
Dead.
But he had this.
I don't know what-- what it does yet,
but I believe it could help get you home.
So I have to go talk to James and get some answers.
Gavin.
Eve.
I'm tired.
I messed up.
I mean, I was just trying to keep everyone safe.
You know?
Anyway, um,
I'm--I'm sorry.
Don't worry about it.
We're all just doing the best that we can down here.
Yeah.
Well, good night.
Yeah.
