Karyn rolled the die across the floor and it came up as ... Zombies.
A grim expression came over Karyn's face as she realized that she was about to become a zombie. She watched in horror as Jon's face decomposed right before her eyes. And she knew that nearly the same thing was happening to her.
After a few seconds, she started to lose focus, as if her intelligence was slipping away from her. Instinct began to take her over. Jon made nonintelligable grunts and moans. And Karyn began to also.
They walked across the room. Jon was dragging one of his legs and Karyn was just walking awkwardly.
There was very little intelligence or awareness left. They couldn't even talk. And at one moment, there was something crawling out of Karyn's nostril. It was a millipede. It then walked across her partially decomposed face and into her ear. She didn't mind it happening.
But, because they were in the room where the die was thrown, Jon and Karyn still had some sense of what was happening. They proceeded to leave the room and go outside.
