I found a new purpose down here.
I think we should get married.
We kissed.
You're the only person down here who understands me.
The exiles are back.
They were looking for this.
This must be Moore's journal, his complete work.
It's our way home.
I don't know if it was James or Kira who sent the exiles,
but I want us to figure this out together.
I do too.
So why are you back?
I told Gavin that I had a plan to bring everyone home.
But the truth is, I don't.
I'm here to kill James.
Where are you going?
I have to get back to Gavin.
But we just started.
You brought me Dr. Moore's notes,
so we could complete his work and get
Gavin and his family home.
We're not making any progress, Dad.
So we'll keep at it.
Gavin doesn't even know I have them.
If I don't get back, you know where he'll turn for help.
You're worried about James.
All those years ago, I-- I swore I'd protect your son
and keep him away from your husband.
I failed.
I'm sorry.
You did what you could.
Still, give me the papers.
I'll keep working on Moore's notes.
You go.
Protect your son.
There's the man of the hour.
Got to tell you, Riley is very excited about your wedding.
Look, this is her idea.
You look very dapper, my friend.
I'm glad everyone's looking forward to it.
Uh, how are you doing?
I'm good.
I'm good, just--
busy.
Sounds like me at my wedding.
I got to tell you, I had my doubts on my big day.
Listen.
Marriage is never perfect.
But from what I can tell, you're built to handle
whatever comes your way.
The gift exchange is the most important part
of a Tonga wedding.
You need to share some of your wine.
What wine?
Who says I have wine?
Oh, my god.
Are you kidding, Judah?
Look, your lips are stained red,
and you smell like Two-Buck Chuck. OK?
Cough up the stash. - OK, fine, fine, fine.
You can have two bottles from Argentina,
but nothing from France. - What?
No need to argue.
There will be plenty to drink.
I've heard the fermented corn is quite good.
Gross. You can have that.
No, you can have it.
No, man, I'm gonna be drinking your wine.
Hey.
I think this would look pretty great on you.
Yeah.
It's cute for a dress that was pulled off a wardrobe truck
and fell through a sinkhole.
- I'm gonna try it on. - OK.
So nice to see her smile like that.
I know.
Maybe a wedding is what everybody needs right now.
Right?
Actually, there's something I need to ask you.
I'd like you to be my best woman.
You've seen me at my very worst and at my best.
I know we haven't known each other long, but you're family.
Ty.
Oh, I would be honored. I would.
What else?
Eve, I went to the building,
and I learned something I need to share with you and Gavin--
alone.
Project Blue Moon-- what does that even mean?
James named the project after a drawing
that Gavin made when he was a child.
So he wants to go back to when I was a kid?
I think so.
If he wants to change his past,
it will also change all of ours.
Gavin will be raised by James.
You and Eve will never meet.
Josh and Izzy--
They'll never be born.
And I'll never come to 10,000 BC.
I'll never find the second chance I found here.
We can't let this happen.
How do we know this is even real, OK?
Ty heard this from Kira,
the woman who sent the exiles to attack us.
How can we believe anything she says?
It wasn't just Kira.
In my session with James, I saw his desire to go back.
And you saw that he was willing to sacrifice
his own grandchildren?
I don't know.
But I may have a way of finding out.
I invited James to the wedding.
Gavin, we can talk to him,
find out the truth about Blue Moon.
Could work.
Can you give us a second?
I do not like this.
My father is the only one who can save your life.
He can use that channel to fix the machine
and send you and everyone home.
But I'm not willing to sacrifice the lives
of our children.
Which is why I won't give him the journal
unless I'm sure about him.
I meant what I said yesterday.
OK?
From now on, we make choices together.
I won't do anything unless you agree.
I trust you.
Ty just told me about Blue Moon.
We have to stop James.
I told Gavin I would give him a chance.
I have to trust him, Levi.
I can't risk throwing everything away.
Gavin isn't seeing clearly right now,
because James is his father.
He's gonna be protected at the wedding.
I don't know if I'm gonna be able to get close to him.
But you're family.
You can.
Are you hearing what you're asking me to do?
What I'm asking you to do is make sure
that Josh and Izzy stay safe.
Now, the only way to do that is to kill James.
There's no other way?
You know me.
I wouldn't be doing this if there was.
As long as he is alive, he is a threat.
Please, Eve. I can't do this without you.
I can't figure out how Aaron had this journal.
He has some connection to this place,
but I don't know what it is.
So the guy has that book on him the whole time
you're with him, and he never says
anything about how he got it?
Never.
But look, he added something to it on the last page.
Here. That's Aaron's handwriting.
What are those, Bible verses?
Same ones he made us memorize.
And look how he wrote them.
Some are horizontal.
Some are vertical.
It's like some puzzle, but I can't solve it.
Hey, don't beat yourself up about it.
I mean, maybe the Bible verses don't mean anything.
But it does.
I can feel it.
Aaron always said that these verses
served a higher purpose.
I just thought he meant getting into heaven.
But now I think that he must have been
talking about something else.
You know, I hate the fact you still got to think
about this creep.
He took away so much of my life.
I just want all the things that I went through
to be for some purpose.
Hey, whatever it takes, we're gonna figure it out.
I'm here for you.
OK.
Hey, lovebirds, you guys coming or what?
Thank you for coming.
Today is the chance to celebrate.
Here in this fort, we are people of mixed cultures.
With our union here today, we look forward
to welcoming even more.
Please enjoy the bounty.
- Great. - Oh, thank you.
Everything OK?
You know, it's funny.
Just a short time ago, I was a man with no future.
Now I've got one, and I'm terrified
of someone taking it away.
We can't control tomorrow, only today.
But today is good.
There's no DJ, no photo booth.
But I heard there might be some dancing.
I didn't know you could dance.
Are you kidding me?
Back home I'm--
kind of a legend.
Never do that again.
But you could talk me into a slow dance
since you clean up so nice.
Why, thank you.
Uh, guys, I think I need to leave.
You just got here.
The warriors are giving me wedding gifts
because I killed Taamet, like I'm some kind of hero.
Look.
Sweet belt. What's the problem?
I have been doing everything that I can to try and forget
the fact that I stabbed a man to death,
and I really don't want a trophy for it.
Then there's that girl behind me.
She won't leave me alone.
I need a mindful moment.
Gavin, how does it feel to be back home
after all these years?
It's a lot to take in.
I remember a lot of it-- the garden, the smell of the fire.
That's where you used to sleep.
Come.
Let's meet some old friends. - OK.
You go ahead. I'll catch up.
Levi?
What are you doing?
This is the Datura flower.
It's a slow-acting poison.
All you have to do is remove its seeds
and put it in his drink.
All right, listen. I've thought about it.
I'm not on board with this.
Eve--
I know the risks, but I made Gavin a promise.
And I'm not gonna go back on that.
- He'll understand in time. - How?
Because this is about your children.
Yeah.
And if he's right about James, then he can save my children.
All of us can go home.
No, Eve.
Why is this so important to you?
Because James took everything from me.
My wife--
My wife is dead because of him.
So maybe I can stop him before he takes
your family from you as well.
What happened?
Marissa and I were tracking sinkholes together.
One of them caught us by surprise.
The building collapsed.
I survived. She didn't.
I'm really sorry.
I really am.
But when you said Gavin wasn't thinking straight,
there's no way you are either.
This isn't who you are, Levi.
You're not a murderer.
James is responsible for those sinkholes.
He has blood on his hands.
Do you want to have blood on your hands too?
When Gavin was drinking and I was spiraling, I was so lost.
And you reminded me of who I was.
You steadied me.
Please let me be that for you now.
Please?
Thank you.
Let's get back to the wedding.
James.
I'm so glad you decided to come.
Well, it's an honor to be included.
It's been some time since I've been to a good celebration.
Come on, please.
So how are you?
I am--
well-rested.
You know, last night I thought about everything you said,
and something clicked.
I had my first sound sleep in months.
For so long, I thought there was
only one possible relationship with my son.
And now?
Now I'm learning to see that you have to appreciate
what's in front of you.
Gavin.
It's good to see you.
Thanks for coming.
What do you say you show me around?
Yeah, please.
You need to come join everybody at the party
and have, like, a little bit of fun.
Just keeping an eye on James.
I'm not crazy about letting him in.
I don't like it either.
But I know that's not the reason why
you're sitting all alone.
OK, fine.
Maybe all this got me thinking about my wedding.
Did I ever tell you about this tiny church we got married at?
Only about 100 times.
Yeah, well, sometimes it just feels
like other people are moving on, making new memories here.
And mine are all still back home.
Dad, we're gonna go home soon.
We found Moore's journal.
Caroline's working on the notes now.
These are all really good things.
So you did find something in Moore's cave.
Josh.
Hey, come on.
Can we talk about this?
I think I heard plenty.
I'm sorry I lied.
After everything we've been through,
you still don't trust me?
No, Josh, this isn't about trust.
Caroline made me promise to keep this a secret.
Not from your dad.
So it sounds like maybe it's just about me.
I could slip 'em a few oranges,
get them to play "Brown-Eyed Girl."
You all right?
What's up?
I thought coming to the wedding
would help me get my mind off those Bible verses,
but it's not working.
You know, I might know how to fix this.
If you're up for an adventure.
How could I say no to that?
Did she say why she's here?
No, just that she wanted to speak to you.
Kira, you can't be here.
How are you feeling, Doctor?
You've taken me away from my wedding.
What is it that you want?
To talk about James.
There's nothing to talk about.
I heard you sent the exiles to our clearing.
I was only following James' orders.
He is obsessed with getting that journal.
Until he has it, he'll hurt anyone he needs to.
Let me in, Ty.
I can stop him.
And I will use that journal for the greater good.
Why should I believe you?
Because I actually care.
I joined this project to help people, to save our world.
James is only thinking about himself.
And what if I told you that you're wrong,
that he might have changed?
Then I'd say he's gotten inside your head.
The moment he has that journal, you'll see who he really is.
It's time for you to leave.
I'm sorry to say this on your wedding day.
This will not end well for you.
Keep your eyes closed.
Well, we're here.
Oh.
You can-- you can open your eyes.
Nature's hot tub.
What do you think?
I think it's amazing.
But that's not all.
No. Is that a Pop-Tart?
How did you--
It sure is.
How did you...
Uh, Lucas, how is this supposed to help me
figure out those Bible verses?
It'll take your mind off it.
Sometimes when you've got a problem,
the best thing you can do is just walk away for a bit.
Mm.
So jump in.
Relax.
See if it helps.
Come on.
It's really nice.
Oh, I-- I won't peek.
You're right.
This is relaxing.
Ah, see?
I told ya.
You're back.
What the hell is James doing here?
Maybe first you should tell me where you've been.
I was worried.
I did find a piece of Moore's work, pages of his notes.
I've been with my father trying to make sense of it.
But we couldn't.
OK.
There's something I need to show you.
We found this yesterday.
It's Moore's journal, his completed work.
Let me take a look.
OK.
So this is where you grew up.
Yeah.
I wish I could remember more from before then, but,
you know.
Hey, after we figure this out,
I'm gonna take you to a spot you loved.
It's up on a hill.
You used to picnic and watch the mammoths move
across the valley.
It's--it's beautiful up there.
You know, I'd really like that.
I would.
You should go.
Thank you all for being here today.
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.
Today is one of them.
We're surrounded by friends, family,
and the people we love.
No matter what time we're in,
those are the things that matter.
You've each been given a handful of seeds.
When you throw them, we each share in the blessings
of this union and this day.
You know, there's one of my traditions
I'd also like to share.
May I?
Now let's celebrate!
Can you save some for the rest of us?
Sorry. I was just--
You were swiping booze at a wedding
when no one was watching.
Your secret's safe with me.
You must be Josh.
I'm James.
I know.
It's nice to finally meet my grandson.
Looking at you is like staring into a mirror--
a very old mirror.
I'm sorry.
This must be a lot.
You know, we need to break the ice.
Fermented corn.
It's not as bad as it sounds.
No, not at all.
See?
Ice officially broken.
Tell me more about you.
How are you enjoying the wedding?
The drinks are good.
Girls are complicated.
That sounds a lot like my teenage years.
So even in the future girls crush your soul.
Oh, yeah.
I wish I could tell you that our species
has evolved as much as our technology, but no.
I see you two have met.
I would say we've become fast friends.
Yeah.
He was giving me some relationship advice.
You want some real advice?
What I've come to realize as of late
is that mistakes are made in every relationship.
All you can do is apologize, hope you've learned a lesson,
and move on.
You can't move backwards.
I like this version of you.
Being outside of the building suits you.
Look at us, three generations all together.
I wouldn't trade this day for anything.
- Hey. - Hi.
You having fun?
Yeah.
You have some admirers.
Why don't you go talk to 'em?
It's a wedding.
Have fun.
Maybe later.
You all right?
It's probably nothing, but--
Levi seemed a little off.
I know. I know.
I think maybe being at a wedding
just brought up feelings about his wife.
Yeah.
That's what I thought, so I followed him
just-- just to talk.
But he was picking flowers.
What flowers?
Ones that Scott told us were poisonous.
Mom.
Mom, what's going on?
Eve, everything OK?
Yeah.
Yeah, everything's gonna be fine.
I was just given the most inappropriate gift
for someone dealing with the emotional fallout of killing
a man with a freaking dagger.
You want to leave?
No, man, I want to keep drinking and play
my favorite game, No Filter.
I've never heard of that.
Easy to pick up.
Just point at someone and say the truth about them
without any--
Filter?
Yeah.
OK.
Uh--
is convinced those dance moves are sexy.
Someone really needs to talk to him.
Right?
Mm... bah!
Very attractive when she's angry.
No, dude.
- What? What? - Scott.
Oh, come on. Come on. Get over it.
Real talk.
Your turn.
Fine.
Uh--
Prefers lying over the truth.
Wow.
That got dark quick.
This a fun game.
Can I play?
Worried about what I'm gonna say next?
Go on and get us all drinks now.
Love that idea.
I just want to ask a simple question.
You like my daughter?
Is it OK to say yes?
Well, if you like someone, you want them to be happy.
So why are you both miserable at a wedding?
I'm-- I'm not sure I want to have this conversation.
Well, we're having it.
I know you've gone through some tough times with your parents.
You've seen what secrets can do to a relationship.
You're afraid of the same thing happening to you.
Yeah.
Yeah, I guess that's kind of it.
I understand how you're feeling.
But a lot of this relationship crap
boils down to one question.
You want to be right, or you want to be together?
Caroline.
You're here.
I should go.
Please.
It doesn't have to be like this.
Do you think maybe we could talk for a bit?
You sent agents after me, exiles after my family.
And now you want to talk?
I didn't know about any of that, I swear.
You know about every decision that
comes out of that building.
Times have changed.
There are others who see the project
very differently than I do.
I am capable of many things,
but hurting you was never one of them.
I don't believe you.
Whoa.
Easy, fellas.
I just want to have a drink with the big boss man.
It's all right.
Any friend of Gavin's is a friend of mine.
- Hey. - Hey.
Wanna dance?
So I have this habit--
more of a ritual, actually, from the air force.
Every time I'm stationed somewhere new,
I find the guy in charge and buy him a beer.
I'm kind of a guest here, but a wise man
never turns down a free drink.
Cheers.
- Everything OK? - I'll be right back.
Stay right there. Don't move.
Hey, Levi, I think you accidentally grabbed my drink.
I don't think I did.
We were just trying to have a conversation.
Yeah, sure, I know.
I just wanted to get my drink back.
No need to argue on my behalf.
Thanks.
My mistake.
Let's get back to our friends.
Yeah? Can you excuse us?
Yeah, no problem.
Let's have a drink another time.
Definitely.
OK, that bite just changed my life.
You have to try this.
No, come on. I got it for you.
So did any of this help?
So far I got nothing.
It's been a pretty great day, though.
Silas, hey!
Hey.
You have to help me.
I have to get to my grandson.
You're all in terrible danger.
I thought we agreed you were done with this.
I know you were trying to help me earlier,
but you're the one who's not thinking clearly.
James is dangerous.
Levi, after everything I've seen today,
I think maybe he deserves a chance.
So he got in your head too?
Levi--
Hey.
What's going on?
Whatever it is, you two need to tell me right now.
Gavin, Levi tried to kill James today,
but it's over now.
I was trying to protect your family.
You knew about this, and you didn't talk to me?
I mean, I thought we were past all the secrets.
Clearly, I was wrong. - Gavin, just hear me out.
No, no, no, no. You and I, we're through.
I don't want you anywhere near my family.
I have to check on Caroline.
Silas!
He's been shot.
I'll go get Sam.
They're here.
Who?
- Caroline? - Gavin.
Gavin.
Uh-- listen.
Something terrible has happened.
I found her like this.
She's gone.
I'm sorry.
Mom.
I'm sorry.
Did you-- did you do this?
I would-- I would never. Why would--
For the journal.
What journal?
She was trying to protect me from you!
I should've never let you come here.
You did let me come because you know-- you know
deep down that you can trust me.
No.
I needed to know the truth about you, about Blue Moon.
If you want the truth, Gavin, I can give that to you.
Blue Moon is real.
I was in pain.
I needed some way to make it stop.
But then I met Izzy, and I met you, and I met Josh.
And this family, your family,
taught me that Blue Moon was wrong.
I did not take the journal, and I would never hurt Caroline.
Well, I don't believe you!
Gavin, stop!
He killed her.
He killed her!
No.
No, Gavin, I don't think he did.
Silas is here.
He's been shot.
What? By who?
Kira.
Close the gate!
She's got Moore's journal!
Let him go!
Take another step and I'll shoot him.
Paara, please, my love, stay there.
I don't want you or anyone else getting hurt.
I'll be OK.
I promise you.
Get in the truck now.
Are your scouts back yet?
No.
They're still tracking Kira.
We are gonna do everything we can to get Ty back.
I'm sending my people to a village south of here
to gather more warriors.
When we go after Ty, we go with force.
Hey.
You know, when I was a kid, I used to imagine meeting her.
She'd take me for a drive, and she'd tell me everything--
her funny stories, her favorite food.
We never did any of that.
I barely know a thing about her.
You know she loved you.
That's all that really matters.
What happened today?
I thought we were in this together.
When Ty told us about Blue Moon,
I got really scared for the kids.
It was all I could think about.
And then-- and then Levi came to me and he wanted my help.
So you considered it.
Yeah, but just for a minute.
And then I shut it down, and I thought he did too.
Yeah.
Gavin, I made a mistake.
You know, one way or another, I feel like my entire life
I've been fighting to put my family back together.
Please don't stop trying.
Please.
OK.
How's he doing?
Sam thinks he's gonna be OK.
Want to tell me what this is?
I asked Silas if he knew Aaron, and he did.
Silas said he worked in the building.
Holy crap.
He was a computer engineer, worked in the basement.
He was like, nobody important.
But he had the journal.
Well, I think he stole the journal.
And he used the portal to get to our time.
Silas said that he would take work from other scientists
and try and pass it off as his own, try to get noticed.
Yeah, once a creep, always a creep.
He acted so smart, so in control.
Anyway, the computer thing gave me an idea.
Programming is all numbers.
And Bible verses, also numbers.
If you write out just the numbers of Aaron's Bible
verses the way that he put them in the journal,
what does that look like to you?
Longitude and latitude.
This is a map.
What-- what do you think it's for?
I don't know.
But I have a feeling it's gonna help us get everyone home.
I did it, Lucas.
I beat him.
Thanks for helping me.
How are your children?
They're hurting.
We need to know more about Kira.
I have known her for years, and I never saw this coming.
But since both my guards left with her,
it's safe to assume she's now in charge of Lazarus.
She'll tell you it's for altruistic reasons,
but the truth is, she's always wanted to be in power.
Do you think there's any way to reason with her?
No.
She sees everything outside the project as a distraction.
And given you tried to destroy the machine,
she'll never let you near that building again.
We need the machine to save Eve's life.
Well, then it's a good thing I kept
a few secrets from Kira.
You have a way into the building?
I do.
We can get back inside together if you
are willing to trust me.
