Oswald chuckles at the end of the story.
"On that happy note, it seems everything's peaceful, I haven't heard any activity at all outside. You guys can probably go back to your cabins, if you want to."
"What're you looking for?"
Oswald realizes something, gets up and walks over to a jar with a strange liquid in it. He takes it and puts it away in a safe place so that the other's don't accidentally fuck with it or anything.
