Holloway's log. The eggheads are at it already. Dr. Gaines was working in the lab, shooting soundwaves at crystals and pissing off his mutated test subject. Well what happens when you piss off a mutie? It breaks out of its cage and turns you into a human pretzel. They all swore that 'protocols were in place,' that they'd 'double checked.' We saw how well that worked out. Won't be the first time, won't be the last. Shame, though. Of all these schmucks, I liked him the best.
