Serious

Damian and Joseph looked back in horror, their eyes widening in shock. What should have been a frail young woman suddenly became a monster in their eyes. There was nothing about her innocent expression that left them with any sort of ease any longer. 

The amount of torque you would need to twist a human's head off, let alone from such an odd position, was enough to make them shiver down to their cores. This young woman looked no different from any other in her early 20's. Yet, the strength she displayed was beyond the realms of reason. 

"Keep running!" Joseph barked. 

The young woman continued to observe the running group, her breathing hiccupping into a bubbling giggle every so often. It was as though she had overexerted her body, but her brain had yet to register the fact. It short-circuited, trying to decide whether she should prioritise laughing or breathing deeply. 

Damian and the others entered a state of high alert.
