I also like that he chided her first about it - with the "before your time" thing.
I dunno... I guess that I figured that they were always going to address the age thing, but never - the first time - as a joke. Grissom used the phrase "young and beautiful", but that was on his own. I meant together. It seems like every GSR fanfic has him going, "Sara, I'm old - why do you want me?"
But judging from that scene, I'd say that it's more likely that if he ever did say that (which I doubt) that it was beat down pretty quickly.
Well, judging by the smile he gives her, and the cautious one she returns at the end, maybe Grissom was joking with her there, too. Like he could tell that that's what she thought, and with all of her romantic suppositions for why they didn't share the same bed, he wanted her to address the elephant in the room.
Again, I think they were together here, but either not sleeping together, or not staying over afterwards.
And the smile was maybe to say, "If that's what you think, stop it"
STONE HER!
Oh, c'mon - look at the grades. You know we're all Teacher's Pet Nerds.
Ziggy skipped, like, three grades in school.
The part I like the best about his burn out (and obviously there isn't much) but what I like is that before, when they weren't together, if there was a problem between them, he'd pretty much avoid her, ignore her or be short with her.
In Happenstance, he starts out being short, but it's more because he's in the middle of a book. Then he stops to share a passage with her that he obviously thought was nice. She, unfortunately, takes it the wrong way, but what I like is that even when he's at a bad place, he still wants to share with her or take her advice - hence the Port Mortem scene where she smilingly thanks him for giving Greg some support.
And it could be because Grissom now feels responsible for two people in his personal life, so while that's been rewarding, the real pressure might come from the fact that he can't work as late anymore, or doesn't want to. Sara coming in in Happenstance kind of reaffirmed that. He comes home early to be with her - or at least did, before he had to mill over Williams.
And maybe he begins to wonder if dating her isn't causing him to take away TOO much time from work...
Who knows?
Like I said - I'd rather Grissom leave their relationship a question mark so he can fully be a tabula rasa, and then return figuring out that he does, indeed, need to be with her.
Why? On many levels. The first is that it would be like a replica of a getting-together moment that we didn't get to see. The second is that I don't want to feel as though Grissom is trapped in the relationship and can't think that over as well.
is really really sweet ,maybe i am a dreamer i know
