The Protagonist:
[Points gun at wall and multiple bullets fly into the gun] Why does it feel so strange?

Laura:
You're not shooting the bullet, you're catching it.

The Protagonist:
Whoa. [Walks up closer to the wall] I've seen this type of ammunition before.

Laura:
In the field?

The Protagonist:
I was almost hit.

Laura:
Then you were exceedingly lucky. An inverted bullet passing through your body would be devastating. Not Pretty.

The Protagonist:
These look like today's.

Laura:
They may have been made today and inverted years from now.

The Protagonist:
Where did you get them?

Laura:
Came with the wall. I was assigned it, like all the material I'm studying here.

The Protagonist:
Do you have an analysis on the metals?

Laura:
Sure. Why?

The Protagonist:
The mixture of the alloys can tell me where they might have been made. Look...I'm not seeing Armageddon here.
