I imagine it wasn't half of her backstory when they held the audition, otherwise they probably would've put more work into what that backstory was. I think they only put it in to explain why Lindsay would be disappearing for x episodes, and I think they created it drawing on the element Belknap had already added to the character - her tendency to push people away/hold them at a distance. Which brings up your point about Lindsay being written for the purposes of being warm and enthusiastic - I don't think anyone who suffered tragedy in their past would be warm and enthusiastic to any person she met, boss or coworker or no. Maybe she was initially written to be warm, but the fact that the writers decided to run with Belknap/Lindsay's coldness indicates that they probably saw it as a far more interesting dimension. They could have put a lot more thought into the storyline, though, and I'm still of the opinion that Belknap bungled it because of the Over-the-top-ness of it. I don't know how well Emily Procter could have acted the part, but in the more emotional episodes I have seen her in, the slight hardness to Calleigh's character is more believable because of the comparatively understated nature of her tragedy(ies). Alcoholic dad that she looks up to, parents in a bitter divorce, ex-boyfriend kills himself on the job. Things like what Lindsay went through usually leave people with severe PTSD, especially if they went through them as kids - they don't usually become warm-and-enthusiastic cops in New York. Well, I think Belknap pushed this as far as it could go, what with the buck-knife, and the ongoing tale of the Graveline tours, and etc. But like you said, Montana isn't outer space, it's not even international, so there's not a lot of definition it can give a character. It would be like trying to make a backstory out of Mac being from Chicago, or Adam (or is this just AJ?) being from Vancouver. Yeah, I definitely agree he wowed everyone, and he did give inflection to the line he was given in the episode. But I remember that line - it was in Bad Blood, and thinking back on it, if it was the only thing I still knew about Adam, I wouldn't have pegged him as the endearingly-nervous guy we know him as today. It sounded more like he was standing up to a guy he was routinely picked-on by (lol, Danny ). But in the same way, I think this is how Lindsay was (though badly) fleshed out when S3 came along. Well yeah, I agree she was a character written to be sassy and loveable. But this is like putting a bungling-someone in charge of a head office based on the recommendation of a friend, while passing on a capable-someone who was actually interviewed and is known to be good at their job. I know that this sometimes happens (and Lindsay's intended role on the show probably isn't as important as hiring a CEO or other kind of executive), but if the casting for the CSI shows is generally good, this seems kind of irresponsible. If her audition sucked, why would they imagine she'd get better because Hill said she'd get better? How would he know?
