Brian smiled back. "I'm persistent. Remember when you said you didn't want to have sex? Where you wrong or what? Besides, I like to keep trying; it's fun." It didn't even matter if he ever got his way. The back and forth was enjoyable, and the fact that John could joke about it proved that he was smarter than these so-called grown ups.
He snorted at Callen. "What type is that? The type who has fun?" Brian frowned. "Wait, would I be the agent? Because then I must have learned that lesson really well since I'm volunteering nothing, not that there is anything to volunteer in the first place. Just because you and mind reader over there – even without his power - think that I have one, it doesn't mean that I do."
He grinned at John. It would always be amusing to have a teenager sounding so mature even while trying to reprimand him. "I think the boss would be very happy to know that you're in such good hands," he said, knowing that it couldn't have been further from the truth. The man would probably have a heart attack if he ever knew about a threesome. Of course, the entertainment died out with one simple word from John. He loved watching people get angry because of him; he did not enjoy listening to people plea with him, especially when they were people he cared about. He might not show it, he might not react like people wanted him to, but he didn't like it.
Brian straightened up and stared at John for a moment. The things he did for teenagers. "All right, let's go home," he said, finally. He took his arms off of John and turned toward Callen. They were too close for what he wanted to do, which made it even better, because when he changed into a panther, his head was practically against the man's crotch. He yawned, opening his mouth as wide as possible, before changing against into a much smaller cat and walking away only to turn into human form next to John again. He put his arm around John and stared at Callen and then Derek. "I can do lots of them, and I'd show you all of them, but I prefer teenagers to boring middle-aged men, so I'm going home."
