Vet of both Iraq wars. Loner. Survivalist. Smart. Bad heart. Greer hates having anything upset his routine. If there was a way he could disappear from human involvement he would think very seriously about taking it. He’s not particularly good at the long term, tending to focus on taking care of what’s now. But he’s also not stupid. He listens for others out in the world because he KNOWS eventually he’ll have to step outside.
