I'm responding to a few different comments by a few different people, but I didn't quote anyone. I'm lazy today and I know you're all smart enough to figure it out anyway.
I agree that Danny isn't a player, and I don't think him being intrigued—attracted--whatever by another woman makes him one. It doesn't mean he's going to hop into bed with the first chick he sees either. If he was that type, he'd never have taken all of Lindsay's shit and waited around for two years until she decided she wanted to bang him. A player might have pursued her for a little while just to boost his ego and prove he could get into her pants, but they'd never stick around for all Lindsay put Danny through. They'd just move on to the next conquest.
I also agree that "she's not all Danny thought she'd be" could end up being the key to their undoing. And I’m totally on board with the idea of Lindsay being the lab bitch. The franchise has always shown conflict between characters, but they've never had someone--who's a main character--on any team who was a completely unsympathetic character who doesn't get along with anyone. I love shows where there's someone I love to hate, and I'd much rather hate Lindsay because that's what TPTB want for her character instead of hating her because I think she's underdeveloped and useless to the show.
As for this Kelly chick, I agree whole heartedly that having some blonde, skinny, white Barbie-esque person is boring and insulting to the audience. DI-VERS-ITY. PTB--pick up a dictionary and look up the word. You may find you like it and that it will actually help the show on a few different levels. I mean, come on. If Adam dated a Suicide Girl, what could he possibly see in some stereotypical pretty, skinny blonde? Of course I'm speculating about the stereotypical part, but with Kelly's initial description, it's pretty easy to get worried. If she's gotta be blonde and thin and "beautiful" (read: the Hollywood version of beautiful), I hope, dear PTB, that she'll at least be interesting.
You know what character I really miss from CSI: NY? Dr. Giles. Here was a handsome, intelligent doctor who just happened to be in a wheelchair. And surprisingly, because it rarely happens when casting parts for persons with disabilities, the actor was a handsome, intelligent man who just happened to be in a wheelchair. Granted he wasn't a main character, but I loved seeing him; and I was so impressed with how TPTB made him just another character instead of making some big thing out of his disability. Now, I admit I'm completely biased about the character since I have a physical disability myself. There are lots of different people in the world; it would be nice if more than the pretty, white, thin, able-bodied (damn I hate that term, but I can't think of a better way to say it right now) ones showed up on shows like CSI: NY more often.
