The guys never saw Derek with anyone, let alone a woman. He looked as if he could crush them with his bare hands, so they never really questioned it. This one however had somehow managed to sway him away from work all together. He even left with her without saying a word! He just....walked off. They didn't dare ask him now, but there would definitely be something to talk about come the next work day.
Thor took his lady love's hand. She could still be a guise, and he had fallen for it again. He would be a fool then.
