James laughed again. He couldn't tell if she was oblivious to the fact that he had just kind of insulted her, or if she simply didn't care and bulldozed right over it. Whatever the case, he was warming up to her more and more. And to be honest, he would have considered himself one of the killjoys, but if she didn't see it that way, fine by him.
The sudden outburst made the agent take a step back and give her a disapproving and concerned look. He was quiet for a moment, shoving his hands in his pocket thoughtful. "I think you are being too harsh on your teachers. You certainly can't teach what you don't already know. And I think some of them may realize there are enough people who want the glory and the excitement of an agent's life, and not enough who want the dullness of a teacher's life." James didn't mean to belittle the teaching staff's accomplishments - that was his point. He figured that Tori saw an agent's life as glorious, as important, and a teacher's as somehow the opposite. He disagreed entirely. Aside from that, there was a slight twinge of... something at her indication that she wanted to be the best Centurion agent. By learning from him. He who had considerable secrets.
The twinge was brief, though, and he had to chuckle at her suggestion that he would have restless nights because of her. That was doubtful. "Alright. Let's go," he said, heading back toward the building. They'd need somewhere high, and that was quickest.
