Are they or aren't they in a relationship? What evidence do we have? Let's put them in chronological order.
Evidence nº1: Committed at the end of the episode:
GRISSOM: Well, jail or no jail, ... I don't think she'll last six months. She'll die without her son.
SARA: That would be better for both of them.
Was she talking about her relationship with Grissom or was she talking about her past? The look on Grissom's eyes tell me the first. So It makes sense to me that in this episode they weren't in a relationship. He cares for her but keeping a little distance between them
Evidence 2: Grave Danger
At the begining of the episode, after the credits, they were discussing a case and my question is: What was about the frame and that certificate?
They were interacting like friends, or maybe more. It's like they were seeing how the land lies, testing each other, and when was Grissom so open up? I mean, it was necessary that he gave her all this explanation about the certificate? They were very comfortable with each other.
About the rest of the episode, I don't know. What happend right next after Nick was put in the ambulance? Like i said, I don't know.
Evidence 3: Bodies in Motion
When Sara, Greg, Sofia and Grissom were closing the case about the two teenagers found dead on a car, their interaction it's very comfortable. She take the reins and he is paying attention to her
Evidence 4: Room Service
When she was searching for clues in the car, and Grissom left the scene without a word, a guy asked her:
MTB REP: Why's he leaving?
SARA: Well, that's kind of what he does.
It looks like she knows him. 'Till what point? Well she is working with him for 6 years. In 6 years, you can know how a person works. So this isn't provatory.
Evidence 5: Bite Me
The room scence. I'm not going to put the scene here because all of us know it very well
.
What was that about "i'm going to see the doctor" with a smile? Well in that scene they said a lot of things for me. That's when i realized that they ARE in a relationship, but I think they weren't sleeping together. All these talking about sex, and Grissom uncomfortable...the look she gave him when he said "Maybe they were suffocating each other and he couldn't breath". I don't think she gave him the look "Who are you talking about?" I think she was saying "Bastard! How could you say that?". But it's my point of view. Her hesitation when she mentioned "or...romance".
Evidence 6: Bite me (again)
Sara and Cath found out that the vic's was having an affair with her boss (a parallelism?) and Catherine says: "lovers and co-workers. That never works.
Sara quickly look at her, like she was going to reply her, but she continued talking about the case.
Evidence 7: Gum Drops
When Sara arrived to the scene she said that Grissom called her to help Nick with the case. Why he called her istead of calling Nick? He was primary on the case.
Evidence 8: The missing scene
Well, mystery at YTDAW posted the famous missing scene. But it was true? I mean, (please don't take me wrong, mystery posted a lot of scenes and dialogs that after were showed), what proves do we have? It's like a witness (I repeat, don't take me wrong, she shares a lot of information to us. Like Grissom says "I'm following the evidence", and for me she is like a witness, a good witness, but only that. I repected her a lot and I'm grateful for her. I'm just trying to be objective, that's all).
Well I don't know you, but I really think that they are in a relationship. Everybody or at least most of you think that after the missing scene. I'm just trying to put two and two in all we saw since commited. Maybe i don't get the correct words, but it's my point of view.
I'm sorry if my words have mistakes, i'm not an english native and i'm doing my best to express me in that language.
Wow! Did i put all these words? It's the longest post I ever wrote!
