We need to get to London.

What's in London?

Him.

Here.

Hey. I think I see your Professor.

He was teaching at Tythehurst College when he wrote the book.

Have you thought about what we're going to do if we can't find him?

We have to.

That isn't really an answer.

They're out of cola bottles.

It's bullshit.

I found this in your pocket.

Whose blood is this?

It's mine. I cut myself...

Where?

Show me.

Did you kill Ash?

What?

What are you talking about?

Don't talk to me like that!

And don't lie to me...

I didn't mean to...

I promise, mum.

I really didn't mean to.

Sacha...

Bill wanted to take Emily to a lab so he could keep experimenting on her.

I had to stop him.

What is that to do with Ash?

Ash walked in on us. There was a fight.

I didn't mean to kill him.

It was an accident...

What about Bill?

What did you do with his body?

He's alive. He ran away.

What do you think the others will do when they find out you killed Ash?

They think the aliens killed him.

And if he comes back and tells them it was you?

I was doing it for Emily.

I love her.

You barely know her.

This is crazy.

You kill someone because you like some girl you just met?

I don't expect you to understand.

Oh yeah?

So make me understand.

We have to go.

We have to leave before the others realise what you did.

I'm not going anywhere without Emily.

They will kill you, Sacha.

I won't be able to stop them. We have to go.

You go if you want to.

I'm staying.

I won't let you become like him, like your father.

I won't let that happen...

I'm not a child any more. You can't make me do anything.

Sacha. Please...

You want me to choose between you and Emily?

I choose her.

Come on!

His name isn't on any of the offices, or list of classes.

You think it's the wrong university?

He wrote the book 5 years ago.

Maybe this whole thing was crazy.

I wanted to believe we could change things.

Because I needed to believe something.

You want me to take the first watch?

You should get some sleep.

You think I was wrong to make us come to London?

It doesn't matter what anyone else thinks.

That's not fair.

You know why Sophia went along with your crazy plan?

Because you needed it.

It was for you, because you're so screwed up

you can't even cry when the man you love dies.

You promised her that you'd make a better future for our baby.

I tried.

Was it really about our baby...

or was it a mathematical problem...

something you wanted to solve?

Don't worry.

It's not the first time you've let her down.

You've never been there for her...

I'll wake you in two hours.

I saw a light.

It might be our professor.

There were people living here.

You think he killed himself?

Looks that way.

He bandaged his wrist?

Maybe he changed his mind.

Don't shoot it! Don't shoot it!

What is that?

I don't know.

Wait.

Should you be doing this? What about the baby?

Don't worry. It's okay to carry dead bodies in your first trimester.

You think he'd just had enough?

I guess so...

I'll check the rest of the building.

This data is full of the same constants that appear in the notebook.

You planning on getting any sleep?

Hey.

Hey.

What time is it?

Just after nine.

How's your new pet?

Did you give it a name?

No.

He looks like a Bob.

Bob is really smart.

All this data.

It took me all night to figure out what it is.

-What is it? -Watch.

Wait. You're going to hit Bob with a hammer?

Look at the screen...

It's analysing my movement.

Not just my actual movement.

It's calculating every possible movement I could make...

Look.

This.

Or this.

Or this.

It's calculating all the possibilities in an instant.

And this makes Bob smart?

His sensors work on a quantum level.

I can feed this data into the formulas in the notebook.

It should help me understand them.

So you and Bob are working together now?

Yes.

He's my assistant.
