She's been gone for two years and Gil is doing better with handling it but misses her immensely. He wants her to come home but she says she can't, she has something to do first.
He doesn't quite understand, but he does know that going after her when she told him not to wouldn't be a good idea, and he didn't want to risk losing her forever if he did.
One Monday night she walked into the lab and a very surprised Julie says "Miss Sidle it's great to see you. Mr. Grissom didn't tell us you were coming back."
Sara smiled back and said "Well I didn't tell him. I thought it would be a nice surprise. Is he in his office?"
Julie looked a little confused but answered "I believe so, yes."
Sara thanked her and walked towards his office, passing the break room she noticed that the rest of the team was in and knew she wouldn't be able to walk by with no one seeing her so decided to say hi before going to see Gil.
She walked up to the door and overheard Nick and Greg talking. "I'm telling you Greggo, I don't think doing that will impress this girl."
Sara had to suppress a giggle when she heard Greg's response "But Nick I am telling You that she'll love this sort of thing."
Catherine chose that moment to look up from the paperwork she was reading and took a sharp intake of breath, making everyone in the room look up and follow her gaze. Catherine jumped up, ran over, and threw her arms around Sara who did the same in return.
Everyone else came up and gave her hugs and Catherine said in an irritated yet ecstatic voice "I can't believe Grissom didn't tell us you were coming home"
Sara responded through the hugs with "well he doesn't exactly know I am home."
Nick looked dumbfounded and Warrick just started laughing at the looks on Greg and Catherine's faces as they excitedly said "you came to see us before you went to see your boyfriend?"
"I knew I wouldn't get passed this room without someone seeing me, and decided to grab some coffee for him while I'm here." She said before heading over to the machine and pouring two cups of coffee, making sure to fix his just the way he liked it. Commenting she would see them later and headed towards his office once more.
