Laura:
One of these bullets is like us, traveling forwards through time...The other one's going backwards...Can you tell which is which?

The Protagonist:
[Shakes his head]

Laura:
How about Now? [Barbara holds out her hand out and bullet flies from table into her palm] It's Inverted. It's entropy runs backwards. So, to our eyes, its movement is reversed. We think it's a type of inverse radiation triggered by nuclear fission.

The Protagonist:
You didn't make it?

Laura:
No, we don't know how yet.

The Protagonist:
So, where'd it come from?

Laura:
Someone's manufacturing them in the future. They're streaming back at us...Try it.

The Protagonist:
[Holds out hand over Bullet that doesn't move]

Laura:
You have to have dropped it.

The Protagonist:
[Places hand over Bullet as if he just dropped it, Bullet flies up into his palm] How can it move before I touch it?

Laura:
From your point of view, you caught it...But from the bullet's point of view, you dropped it.

The Protagonist:
But cause comes before effect.

Laura:
No, that's just the way we see time.

The Protagonist:
Well, What about free will?

Laura:
That bullet wouldn't have moved if you hadn't put your hand there. [Plays a recording of the interaction with the bullet both forward and backward] Either way we run the tape, you made it happen. Don't try to understand it. Feel It.

The Protagonist:
[Bullet begins to move backwards on table from Barbara's fingertips to The Protagonist hands] Instinct. Got it.
