Re: Your Thoughts on the upcoming Danny/Lindsay development (SPOILERS!
I don't think it's a good thing, for the show or the characters.
Danny and Lindsay both have flaws, which is fine, everyone does. But when they're together, they seem to really bring out each other's flaws. Now that they're having a baby together, I think that will continue. Danny and Lindsay aren't good together, IMO. Their relationship is immature and unreliable (on again, off again, up/down, each pushing the other away at certain times). They don't really seem to understand what the other wants/needs from the relationship - that was shown in their problems in s4, when Danny seemed genuinely shocked to discover Lindsay thought of herself as his 'girlfriend' - I think up to that point he hadn't thought of their relationship as being serious. And Lindsay pushed Danny away in s3, and then in s4 she was the one wanting more closeness and involvement, the one getting upset about him pushing her away.
Sometimes having a child together can save a difficult relationship. But I think having a baby will only strain Danny and Lindsay's relationship still further. Lindsay has already proved herself unreliable at times - when she was having various problems in s3 about the painful memories caused by what happened with her friends when she was a teen, she ran away from a crime scene, and in s4 when she was struggling with the problems in her and Danny's relationship, she left evidence out, when an inspector was around. What is she going to do when she has the stress of a baby to deal with? That's a big responsibility, and while sometimes having a baby can make a person 'grow up fast' and become more responsible, I can't see that happening with Lindsay. Danny too has his share of problems - he's not the most responsible of people either, although I can see him becoming more responsible with a baby. But he's still grieving over Ruben, still feels responsible for his death - will having a baby, his own child to be responsible for, really be the best thing for Danny right now? Finally, there seems to be a good deal of resentment and confusion between Danny and Lindsay right now, and is that really the best environment to bring a baby into?
If Lindsay was having a baby with someone else, despite my doubts about her ability to be a mother at this stage, or if Danny were to have a child with someone else, even with my doubts about his emotional state re children - I would be happier with the storyline. If Lindsay was in a relationship that was more secure and certain, and with someone that brought out her better qualities (yes, I do believe she has them) then I think she could be a good mom, or learn to be one. Also, at least that way, the character would be more than 'Danny's love interest', and not a character so very much propped up by Danny. I would also be okay with Danny having a baby with someone else. Also, that way, the whole baby thing could be kept minimal in terms of story, and out of the lab, more a short personal arc for either character. But Danny and Lindsay having a baby together....I just can't see it.
From a writing POV, I am really p*ssed off about this storyline. I am sick of the writers messing about with D/L. The constant on again/off again status of it, the way it's written (they sometimes act like they're in a high school drama, not CSI NY, like they are teenagers, not adults in their 30s). In s4, D/L seemed to be coming to an end, and now suddenly they're having a baby together? I also worry the writers are planning to go the 'twu luv' path with D/L, which, IMO, really doesn't fit with the way they've written D/L so far. I personally don't think Danny and Lindsay love each other. There's attraction there, and they care about each other, but that's it. Danny's scenes with Rikki in s4 seemed much more tender and passionate than any of his scenes with Lindsay.
And, just because two people sleep together twice and have a baby doesn't mean they love each other or fall in love. A baby can't be a 'fix all' for a deeply damaged relationship, and it shouldn't be, either.
Finally, I wonder whether the D/L baby will cause problems for the lab in general. Mac and Stella seem to have let Danny and Lindsay's involvement slide, despite a warning from Quinn, but can they overlook this? Maybe Mac and Stella will, as both seem to have the attitude that Lindsay can do no wrong (Mac ignores or forgives her screw ups on the job, and Stella covers them) but what about Gillian and Sinclair?
Do we know for certain D/L will keep the baby? Maybe they will agree to give it up for adoption.
