"String theory?"

"What, you don't think so?"

"I think you got that from the TV show, The Big Bang Theory." The show had been mentioned before to him, he'd given it a watch once though tv in it's entirety couldn't quite capture him.

Tilted head, thin lips curling into something "knowingly", quietly waiting for a reply. To which, Austin shared in this smile before crossing a leg over another. "Alright, you caught me," Spencer means to declare a playful victory but is just short of words when she adds, "I see you got the joke, not many do. Are you a mathematician or a scientist?"

"Behavior Analysis Unit of the FBI." He replied, fixing the fez that threatened to fall if he continued to tilt any further, not having realized he had. "I take criminal and based on-" "I'm aware of job description." Austin interrupted before he could go on. "Actually, I know who you are, Dr. Reid."

He tensed, taking a slight lean back from the other. All exits being mapped for easy access or possible moves he might use to escape. Austin being all of 5'3 and female, even with her fit build, he could manage some tactical moves that Derek had taught... probably -they hadn't been as successful in trial-.

"Not like a crazy stalker. Oh god, sorry, that sounded a bit off. I mean I'd seen you speaking at lecture on Psychology and followed a bit your work via news." She shook her head, face pillowing in a pale pink. Mortified by her lacking ability to sound smooth. And in the moment that her face begun to burn, Reid whether accidentally or not, bellowed out a laugh.

"Oh, you're in school? What are you studying to be?" He'd narrowed it down to 67 possibilities based on their conversation.

"I happen to be a mathematician. More specifically, I work within the realm of game theory." Explaining as she adjusted her bow tie.

She looked all of 18, maybe 22. Ah, there was that feeling he hadn't experienced since the Zodiac copy cat. "Game theory?" Not somethings that's come across in his readings.

"It's the study of mathematical models of conflict and cooperation between intelligent rational decision-makers. Mainly in economics and information. See, it has four essential elements. The acronym being "PAPI", it-"

"Reid, thank god, I have been looking everywhere for you. You couldn't bother- oh, oh gosh, I'm sorry." Garcia flickered between the two. Confused at the sight; Reid talking with interest to a female who appeared to adorn the same Doctor's costume. Relieved to having found him after ten minutes.

"No, it's fine." Austin assured her with a smile, pulling the strap of her book bag on and out reaching her hand to Spencer. "It was nice meeting you, Dr. Reid. Hopefully we meet again."

He took her hand with a firm grip and shook, small smiled. "Please, call me Spencer and I'm scheduled to make another Psychology seminar two weeks from now. I have some things I think you might enjoy."

"It's a plan." She nodded, moving to leave the convention center. And he watched as she faded into the crowd of cosplayers and out of view.

"Who was that?" Garcia probed, a tease in her voice already. She was definitely going to dish on this to the rest.

Reid wasn't sure how to answer quite yet.

I hope you enjoyed chapter one. And I hope you enjoy the rest. Feel free to comment, lovelies.
