Corpse Girl falls asleep suddenly

“I don’t know, now I just worry I’m going to…”
St. George looked at her. “Going to what?”
She stared at the journal for a moment. Then the flashlight tilted and she slumped back against the wall of the tent. It gave under her weight, tilting her enough that she slid down to the floor.
“Maddy?” He picked up the flashlight and spun it around.
The Corpse Girl’s eyes were half-open. She looked relaxed. He lifted her hand and it was limp.
“Whoa,” said Barry. “Is that how she falls asleep?”
“Yeah. Haven’t seen it happen in a while. I forgot how sudden it is.”
