Derek crossed his arms over his chest, regarding her for a long moment.
"You're disobeying another order."
His tone was judgmental, even reproachful. How many times did he have to explain to her that she was not in charge? That when he gave her an order she needed to follow it, even if she disagreed with it? It was like Stiles, all over again.
He sighed and shook his head.
"Go. Now. Before I get angry and punish you for your disobedience."
