He doesn't look up from his writing.

"Made a bunch of notes and maps while I was looking around away from you guys. Sketched some interesting stuff, too. Those pages are all blank now. Trying to write down everything I remember. If we can find some ruins like that place we'll know if what just happened was real. Some good tech to look at too if it survived. Didn't get much chance to see the place from the air though so we'd have to find that one building to be sure."
