If it was any person in the world, Derek would have already seized her by her lying worthless throat. An Argent was tricky and Derek had tangled with this particular one a few too many times before to be so stupid as to get close to her. Knowing Kate, she would have about a dozen surprise weapons on her somewhere and Derek didn't much feel like being stabbed, tased or shot at today.
Using an inordinate amount of self-control, Derek was able to turn his eyes back to their usual green. But there was no mistaking the anger on his face and he didn't bother to hate even a hint of his hatred. And he did hate Kate Argent. She killed his entire family. She was responsible for him being even here. He thought he could see Laura again and while Peter killed her, it was because he had been trapped and twisted by the flames that had devoured his body. It was the fire that Kate set. Everything was her fault.
"I heard you're one of us now," Derek said. "You should do us all a favor, follow your stupid code and kill yourself."
Derek narrowed his eyes at her. That was the problem though, wasn't it? Kate didn't follow her code. Kate did whatever the fuck she wanted and even when she was human, she had a greater bloodlust than Derek would ever have.
Right about now, Derek wished that he had red eyes. He wished that he had a pack of strong betas at his back. He had given it all away, relinquished his deep need for power when he gave up his alpha status to help Cora. Somewhere he knew that what he had been doing was wrong but Derek was afraid. He was afraid of people like her. And now he and Cora were just two betas out on their own. They were the worst of the wolves. They were omegas and that made them weak.
