I found him.

He's a Professor of Neurogenetics at the University of London.

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

We have to.

You think he killed himself?

How's it going?

I'm pretty sure this constant measures

the gravitational force on the quantum scale.

I think they understand quantum gravity.

Who doesn't?

It's only a small step from there to manipulating space-time

on the quantum level.

I think they see matter as a series of interacting waves.

These equations predict the energy

and direction of the forces their interaction produces.

There are videos on the dead guy's phone.

He was keeping a diary.

He had his girlfriend here with him.

Something happened to her.

She left, or she was killed.

Maybe that's why he killed himself?

Look. I found a map.

The university admin building's off campus.

It's not far.

Maybe they have records that can tell us what happened to the professor guy?

It's worth a look.

You going to eat something?

Yeah.

The ripples in space we detected at the observatory.

I think they were caused by a quantum event.

It must have been huge.

What's the guy saying in the videos?

He's just found Bob.

Who's Bob?

It's a nickname I gave the alien creature.

It was injured. He brought it back here to work on it.

Has he said what happened to his girlfriend?

Not yet.

You can see he tries to not think about her. It's too sad for him.

You should watch the videos.

Why would I do that? I have more important things to do right now.

I don't know.

Maybe so you can take an interest in others for once?

Just an idea.

Here it is, look!

Professor Bill Ward, London.

We found him...

What happened?

-It was Bob. -Oh, my God...

I'm okay. He missed my artery.

Dylan didn't kill himself.

Bob killed him.

Wait, I'll find some bandages...

I watched the videos. Dylan helped me solve it...

What do you mean?

If you follow the formulas and notes, I think it's some sort of map,

or pathway.

To where?

The alien who came to the observatory...

he said their journey to Earth took no time at all.

It's not about where the pathway leads, but when.

I don't understand.

They travelled back in time to get here.

They travelled through time.

You said you found him. The professor?

Yes. He moved to another college in London.

It's at a different campus.

You were right. I should listen to people more.

They make me feel stupid.

You're the smartest person I know...?

I'm smart at science.

I find people hard to understand.

You were always so popular.

It was easy for you.

I was jealous. I hid behind my books.

I still hide now.

I see you peeking out, more than you used to.

Did you find out what happened to his girlfriend?

You want to see?

You okay?

Yes.

We should go find your professor.
