The nurse at the cart smiled as a mother would to her child. "Here you go, dear," she said as she put it on the table for her. "Enjoy the meal with your friends. Will you be helping us out again today?"

Benjamin looked from the nurse to Sara; surely she heard it too, the nurse didn't think of her as a member of the staff, but a patient who was allowed to help out. At least, that was his take in her words and the tone of her voice.
But he didn't have long to wonder about that; suddenly Ray snapped and went for Dia. Immediately Benjamin jumped up and grabbed Ray's arm. 
"What the hell, Ray! What's wrong with you?"

Benjamin wasn't the only one who had reacted; two male nurses rushed to the scene to save a fellow nurse from an aggressive patient.
