Walking down the hallway you don’t realize how warm it’s gotten until suddenly you notice sweat is running down your cheeks. You could turn around. You know it’s cooler back there, but then you’re no longer moving forward. If you go back to the benches, where the ceiling goes up an extra fifty feet and the concrete flooring is covered over by lineoleum, where they set up the man-portable fluorescent lamps and the ventilating fanwork, if you go back there and sit down and let yourself cool back down, maybe assisted by a nice cold drink of water trucked in from the surface, if you do that you’re just delaying the inevitable. Sooner or later we all go down the hallway. Maybe later rather than sooner, but it’ll only be hotter later, and then you’ll be back where you started, but older and sweatier.
If it helps, imagine that there’s someone stalking you. Someone not quite human, that they woke up when they came down here and started taking pictures. He’s taller than you’d think, given how low some of the doorframes are, and he’s almost totally silent when he walks on concrete. On the linoleum his feet (are they shoes or are those his feet?) squeak, but you can’t stay on the linoleum forever. You can pretend that he’s got teeth, sharp ones, big ones, and an oddly square jaw to match. Maybe the jaw can distend like a snake’s and he can swallow you up, or failing that maybe he can fit your whole hand into his mouth and bite it off just past the wrist. Maybe then he sucks the blood out of you, at the stump. You can imagine that’s what he’s really after: your blood, hot and wet.
It’s hot and wet walking down the hallway, but if you turn around and go back to the relative cool of the benches you might see him stalking you, and then there’d be nothing for it but to shriek and run and you could basically count your lifespan in heartbeats, then. Maybe you haven’t seen the rest of the team yet, their sucked-dry handless corpses strewn further down the hallway, just around that corner. Is your light flickering? Maybe you should turn it off, to conserve power, and fumble forwards in the almost-dark. At this point in the hallway you can still see light from the man-portable fluorescent lamps, back behind you in the gallery. When you turn the corner, that will be gone.
You slow down as you approach the corner. It’s only natural to fear the unknown. But you know if you stop moving, then the one who’s stalking you will strike. He won’t have any other option; this is how it is, down here. The best you can hope for is that when you turn the corner all the rest of them will be there, hale and hearty and no worse for the wear, a little sweaty but otherwise fine. You can hear something dripping, up ahead. Maybe it’s sweat dripping off one of their still-alive brows. Probably that is what it is.
