Charmer, Kite, the two of you are in a spot. This is the bottom of the station, what was once a small, unfinished, limited-service station a good twenty feet deeper in the ground than the other platforms. Nobody lives down here, and not too many people even want to visit, since it floods out with black water somewhat regularly and the damp left behind breeds weird life ... insects and fungi, generally, but not of types anyone has seen anywhere else.
The actual tracks are never dry, always running with a foot or so of dark, fragrant water, like an underground river. Nobody knows where the water flows from, nor what pool or waterway it ultimately discharges into.
The station, for being such a small platform, is actually quite expansive and complicated. It was never finished, and it seems like it might have been intended to end up much larger, so it goes back quite a ways in cave formations built of rusted supports, cracked and half-poured concrete, and the raw, jack-hammered stone of the the city's bedrock. Here and there, rotten scaffolding is built across wide pits that disappear into bottomless darkness, and partially-built cinderblock walls scatter haphazardly, jutting up spears of rebar.
You two are trapped back in the shadows of this place, hunkered down behind a 10' by 10' sheet of corrugated steel, while Hugo and Winkle search around the place for you. At the rate they're going, you've got some time, but they'll turn you up eventually unless you get a move on. Hugo's girl, Mimi, is over at the broken-down escalator bank with a pump shotgun, so that way's sketchy. You've heard there're other ways up out of here, like maintenance hatches and shit, but you don't know of any specific ones, yourselves.
Winkle's got a light, and so does Mimi - big battery torches, we're talking about, sending shadows crawling around the tangle of this place. If you have a light, it's probably kinda crappy, since I figure a good light is worth barter down here. And it's off, obviously - you're not looking to draw attention, as is.
So, uh. What's got them after you two? Why are you together down here in the first place?
