Wow. You really delivered this time. Throughout the story I kept wondering how much of what he was experiencing was psychosis and how much was reality. Then you made it clear that this was indeed happening.

As for the prompt--outstanding. It would be hard to imagine a story based on 'lens' that would be more on target.

I think we know what happened to Nathan's father. The two of them are possibly exchanging stories in some CIA black hole. Problem is, the lens is still out there (if his mom didn't destroy it). Who will be tempted next?
