Maybe They're All Dead

The screams grew louder as they drew nearer to the fairgrounds, and Charlie began to look anxious.
"That doesn't sound like happy times," she said. "That sounds like terror."
Jen nodded, suddenly afraid to speak. Charlie moved closer and took her hand.
"Don't be afraid."
They walked forward slowly, minds flickering over countless possible scenarios, each less likely than the last.
"The whole town is in there," Jen whispered. "What if something terrible has happened?"
"Except us," Charlie said firmly. "We're okay."
They were entering the car park when a man emerged from the big tent, running at them and shouting.
"It escaped!" He sobbed, and as he drew closer they could see that he was covered in blood from head to toe.
"What escaped?" Charlie asked, instinctively stepping between Jen and the man. He opened his mouth to speak but the words became a scream, as a second figure lurched into view and grabbed him with bloody hands.
