i just realized a strange parallel. if we assume that GSR became canon after Grave Danger, it means that they both made the most direct approaches towards one another after they got injured in/were close to a bombing. first Sara in PWF asking him out, and then Grissom, probably after Grave Danger.
Well, I think a lot of people assume Grave Danger because it came after Committed. While Grissom may have been driven to repair their friendship in that episode, seeing Nick almost die might've made him realize "Sara could've gotten her throat slashed, and you still didn't say anything."
Which is also why a lot of people assume Grissom made the first move (besides the fact that we wanted him to have. lol).
But I think it's kind of natural to assume that a traumatic incident would cause two people to become closer. If they see death every day, it takes a lot to wake them up to something. The potential of losing someone close to them may be something that they've really become neutral to... until they see it.
i mean, Grissom didn't do anything for example after Stalker (but yeah, it was too early).
Well, Grissom agreed to go into a barn with an unstable man who was asking for a ransome to save Nick. I think Grissom would do a lot for his team, he just has a bad way of expressing how he feels.
that's why i doubt he made a move as early as after Committed.
I'd be surprised to learn that he made a move after Committed. It was clear with him leaving her to watch at the end that he understood she needed some alone time to work this out.
of course we can argue if in PWF Sara didn't want to talk to him about it before, but i'd find it strange if she wanted to ask him out in the corridor of the lab in the middle of the shift. maybe she just wanted to give him a hint, but after the bomb she decided to go all the way.
I think it was a matter of working up the courage, and in that sense, it may have had more to do with how he ran over to her and helped her (because that was always in the script, honey was the addition) that sort of emboldened her to say something.
She could sense that he liked her, so until Butterflied she was likely confused as to why he wasn't doing anything about it. Even in Invisible Evidence she seems to be going, "Um... hello? Your body is against my body and we've figured out the case already."
