ok, who can see a Vegas episode coming? i know its a bit obvious, but still, a specialist in being able to recognize involuntary emotional responses to surprising or unknown events, in say, poker, where each drawn card is an exposure to an unknown stimulus; yet a game filled with people who specialize in being able to mask their reactions. come-on it writes itself! you don't even have to throw a murder in it to give it a twist, there's enough deception already. hell, the only person on the team who couldn't play is Loker (just barely though; i can so see him irritating players at a card table, but his honesty...). i cant wait till they do it.
i think, personally, the best possible set-up is that a group of high roller players personally challenge Lightman and the team to a game. i'd say high stakes game, but Litman seems like he wouldn't bother with a game where the only prize was money (which is why i hope its on pride). if i had to guess (or gamble, if you think thats clever) though, id say a casino hires him to investigate a cheater. quick, easy, predicable, but entertaining none the less.
