We've been "working" for the Agent for a few weeks now, and I've come to the conclusion that Jack knows something he isn't telling me. He'll leave the cave for hours at a time, come back exhausted, and go to sleep immediately, not even acknowledging my questions. I'll go to sleep before he wakes up, and then when I wake up the Agent is there, standing over the orbs while Jack sits in the corner.
When they were both gone one day I picked up one of the other orbs - the green one - and stared into it. I saw a man with a large camera taking photographs of trees. The scene shifted, and I saw another person taking photographs of trees in a different location. The scene continued to change, showing many people taking photographs with many different kinds of cameras. I put the orb back, and not much later Jack came running back in, giving me an accusatory stare - somehow, he knew.
I haven't looked into the other ones yet, but I caught a glimpse of something in the blue orb that, if true, means that we are in danger. I am awaiting a chance to look into it and see if what I saw was what is actually there.
If it is, then may God help me.
Actually, that should be god, not God.
