Swamped

Well. No need to overthink things.

"Actually... I think I need to relieve myself. And, well, if it's just going to end up in the latrine anyways..."

She sighs.

"I suppose it means I can get washed up sooner. Be quick about it, though." She starts to walk out. "Don't forget to head to the washing station. Stick to the wall on the left as you leave and it's the first door. Oh, and try not to get near any patients."

Oh, you'll be quick, all right. You get your mask on as soon as she leaves. Then you drag the metal cover right next to the board, and you try to just push the board aside with the cover, so the hole doesn't get exposed. If gas is already making its way through, best not to take chances.

You do see a small plume of smoke slip through a tiny gap between the two covers. It'd probably be bigger if you hadn't done it this way. You push a little harder in hopes of finishing up sooner.

When you're done, you take a closer look at the board. There's some dust on the underside, the same color as the smoke. Must have settled there.

Well, as the nurse said, you ought to wash up. Hells, they might even have a decent shower here - sure, it'll be the sort of shower they had fifty years ago, but that's still probably going to be better than what the Marsh Fortress has to offer.

But before you do that, you might want to look around the latrines some more. Better if you don't have to come back here, and for that matter, you've only seen two out of three for yourself.

So you start off by taking a look at the third latrine, in case you spot anything odd.
