There are a couple questions everyone asks, like "Why/how did the apocalypse happen?" "Why do they all live outside in tents?" and "What happened to Sequel's Brother?" But there are some questions I thought would come up that haven't.
I've got one character who's covered in scars, has a bandaged arms and a bad leg, but no one has wondered why he's is such bad shape compared to the other survivors. (that's a spoiler so I won't answer it)
Theres this moment, which goes unexplained in text but has a secret hidden in the reference:
Thesis’ mouth twisted as he watched her light the cigarette and take a first drag.
“That habit’s going to kill you, you know that don’t you?” He said daringly. Agony huffed out a short laugh.
“Oh yeah?” She gestured around them at all the fog and debris, “Tough fucking competition!”
“Even still. You’d probably manage to out-live all of us if you quit.” Thesis said. Agony didn’t say anything at first. She looked down at her boots and kicked a piece of something or other. She took out her cigarette and eyes it thoughtfully as she rendered a response..
“Have you ever read ‘The Witches,” you know, by Roald Dahl?” She asked conversationally, almost innocently even. Whatever move she was making, you couldn’t see it in her eyes. Thesis gave her a puzzled look. If she was trying to change the subject this was an odd way to do it.
I won't explain it unless someone asks because the implication is actually pretty dark.
