"That place where you had to come get me, I don't know if you looked around at all." She's pulling her tablet out of her bag, turning it on and opening the drawing program, her stylus moving across the screen. "I didn't make the connection right away, because I was so scared. The building that I was in had a lot of equipment that I recognize, though. I couldn't figure out why it was there at first, but then I started thinking about the land around it, the trees, and the bodies of water." She's sketching as she talks, the layout of the area, the building she was in, the uniform bodies of murky water, the shelters where tanks for spawning and the early growth stages would be, even the area for waste reclamation.

It's a hatchery. Up on the top level, among the areas for growing food and storing livestock, they have a hatchery. She just needs to get it all down so that she can explain that to him.
