Swamped

One thing about the lack of people here is, if someone is around, they're going to make noise. Especially if they're running.

Now that you're alone, you just have to sit still for a bit and you can hear the pounding of feet on wood. It's a bit drowned out by the sounds of water tanks pumping, but it's distinctive enough for you to figure out where it is.

You think you also hear something faint... like an insect buzzing. That's odd, inside-out bugs don't make noise, and other insects are pretty rare on a ship. You'll have to look into that later.

You start running towards the noise. Hopefully you can catch up before she does something foolish. You don't even know what she's hoping to accomplish by running all the way down here - she's on a ship, so how does she hope to escape by running away from the lifeboats?

Well, the only other alternative is to get rid of the witnesses. Maybe you should have just reported this to the captain instead of just running around like a fool...

No, your gut's telling you you'd better be down here. Not that you know why...

Hang on. The pumping's getting louder. A lot louder.

You get the feeling you might have more than one problem here.
