Somehow managed to forget to post this one over here, so adding it in now.

  Marion took a deep breath.

"Please don't shout at me," she said, in as pleasant a tone as she could manage.

"Why? You worthless idiot. One thing, I asked you to do one thing and you screwed it up."

"Sir," she tried again, "that was not what..."

"Are you trying to say I'm lying?"

"Mistaken..."

"You're fired!"

"Fired?"

"Yes, get out."

Marion felt a weight lift off her shoulders.

"Gladly," she said as the chains of loyalty in her head snapped.

The beast within her rose, no longer fettered. Fur erupted from her body, long fangs descended, and she attacked.  

Many thanks for reading.
