yeah... the team does LOVE Grissom, but when they find out about Grissom and Sara being together, i don't think they'll really look up to him that much anymore. Nick has ALWAYS looked up to Grissom as a father-figure, but now that he's with Sara (the girl that he wants to be with) it's a whole different ball game. In the past few season (mostly after Grave Danger) Nick seems like he's because... more independent. like, he doesn't look up to Grissom as much anymore, he's like LIKE Grissom now. in the episode "The Good the Bad and The Dominatric", Nick was being completely complimented about being a hero and humble and i think Nick's trying to be like grissom for one reason.... SARA.
Now that the team knows about GSR, i'm not sure how they will act toward Grissom. I think they might act a litle different toward Sara, but i think that they'll just be plain out disgusted with Grissom. They all know that Sara has had a thing for Grissom, but i think they all knew that Grissom would never go with her becuase it's against the department's policy.
In Season 5, when the team split up... OMGOODNESS, nick was SO MAD! i forget what episode it was in but Nick's like: "it was just alot better and easier when we were all on the same shift." and catherine said: "so you don't like me as your supervisor?" then nick said: "ugh.. whatever."
even in the 7th season, Nick and Sara just seemed.. out of it, not themselve UNTIL Empty Eyes. the episode on (since they worked together and Nick was there for Sara) it seems like they just can't get enought of each other and that they want to be together more so they can actually be happy. that's my thoughts on that. i REALLY hope that they will get the romance right and make SNickers happen. GSR was been made to happen since the beginning and that's why i don't think it's a good relationship; because it was PLANNED. SNickers, you can just tell because of their smiles and the flirting. Sara and Grissom had a relationship before but that's what stupid. CSI is all about the unexpected and GSR was expected... now let's just get over this stupid GSR stuff and get right too... SNICKERS!
