Setting: Rafe has been forcibly "hired" overseas, although this is fairly early on during his stint at the lab. He isn't exactly friends with Hollis yet, although they have spent quite a lot of time together professionally and therefore they have probably started to feel each other out a bit. Dashell is Hollis's co-guard, with whom he has an ugly and dangerous past. And Hollis once spent some time in prison, which is why he seems to be having odd concussion-based flashbacks.
