"A party?" Sara asked dubiously.

"Yes, Sara, a party, and you are going. No 'ifs, 'buts' or 'maybe's'". Catherine told her firmly as she handed out the rest of the invitations in the brake room at the start of next shift. "Now, you're all invited" she continued as she sat down "and you can bring a guest or two if you wish, it would be good to have more people." She added, looking at Adam who was smiling at Sara and her annoyed expression. Grissom chose that moment to walk in.

"What are these?" he asked picking up an invitation form the table. Catherine sighed.

"The party I told you I am holding, remember? I rang you last night, you agreed and remember, you can bring a guest."

"Hmmm, how could I forget." Grissom asked dubiously and then looked at Adam and the pair made eye contact. Adam quickly signed something to his father.

'Are you thinking what I am?'

'She wants to meet Rex?' Grissom signed back.

'Yeah, so, should I bring him?'

'If you want, do what you like.'

'Greg knows.' Adam added looking over at him playing the Play station in the corner.

'How?' Grissom signed curious. It wasn't like his son to gossip with people.

'At a bar last night. He, Warrick and Nick where out having a drink, he "warned" me.' He replied chuckling. Before Grissom could respond Catherine left out a large sigh.

"What is it with Grissom's and signing, if you have something to say, say it to all of us." Grissom just looked at her, blinked and turned to the others.

"On with assignments."
