Don't look back. 

Why?

Because. 

What would you do even if I looked?

Nothing. What could I do?

Stop me?

Stop you? Or me?

Is there a difference?

I don't know. You're the smart one. You tell me.

Tell you what?

The reason. Why not to look back.

It was your idea, not mine. You tell me.

Was not. Why would you eaven want to look back for?

To see whats's there. What's behind me.

You came from there. You, if someone knows what is in there.

No I don't. I wasn't looking.

You... what?

I wasn't looking. 

You came all this way. And you don't know what's behind you?

Came all this way to what?

Here.

Here where?

The now, I guess.
