Time goes by quickly and soon it is time for Catherine's 4 month check up at the doctors. Nick is walking with her and she is noticeably pregnant now. She has a healthy glow about her and she and Nick are holding hands. They are talking quietly and Catherine looks up at Nick and smiles. She laughs and says "You didn't have to come with me. I am feeling much better and…."

Nick stops her as he says "I wanted to come. Besides, that is my baby too. I want to be there for everything."

Catherine smiles as they walk inside the doctor's office. She signs in and goes to sit beside Nick. He is talking with another couple and smiles as she sits down. They talk quietly until Catherine's name is called. Nick stands up and walks with Catherine to the door. The nurse has her step on a scale where she takes her weight and records it on her record. She smiles and says "You have gained 5 pounds."

Inwardly Catherine groans and she hears Nick let out a little chuckle. She gives him a look and can't help but laugh at the smile that is on his face. He looks so handsome. Once they are inside the exam room and the nurse leaves she motions for Nick to come to her. He smiles and walks over to her. She smiles as she kisses him. They are lost in each other. At least until they hear someone behind them clearing their throat. They reluctantly pull apart and see the doctor standing behind them. He is wearing a smile on his face and says "Hello, Catherine."

Catherine smiles and watches Nick sit down next to her. She is totally focused on her husband and the doctor smiles and says "So, how has the morning sickness been?"

Catherine shrugs and says "Not as bad as it was in the beginning. I am actually able to keep some food down now."

The doctor laughs and says to Catherine "Well, if you want to lay back, we can start the exam."

Catherine lays down and smiles as Nick takes her hand. They are only half listening when they hear the doctor say "Ummmm, I think I need to do an ultrasound. There seems to be something odd here."

Catherine and Nick stop looking at one another and are suddenly focused on the doctor. Catherine looks at the doctor and says "Is there something wrong with the baby?"

The doctor shakes his head and says "No, but I do believe there is more than one heartbeat and…"

Catherine looks at him and says "More than one?"

Nick is speechless and sits there opening and closing his mouth. Catherine laughs and says to him "I think this is the first time I have ever seen you speechless Nicky!"

Nick laughs but says nothing. He merely watches as the doctor sets up for the ultrasound. He watches as the doctor proceeds to perform the ultrasound. It is at that moment that Catherine and Nick see their babies for the first time. The doctor is quiet and says nothing while he is performing the ultrasound. He smiles at Nick and Catherine and tells Catherine to get dressed and that he will see them in his office. They look at each other and smile and Catherine gets dressed and they walk into the doctor's office. The door closes and the screen goes black.

Nick and Catherine are walking out of the doctors office. They look like they have been knocked for a loop. Each is speechless as Nick opens the door for her. She says nothing and simply sits in the Denali. She smiles as Nick climbs in and starts up the car. Finally she finds her voice and says "Can you believe this? I..."

Nick smiles at her and says "Those were my thoughts to. I can't believe it."

"Who would have thought that…."

"Wait until the team finds out about this. First us and then this…"

Catherine smiles up at him and says "Are you happy? I mean are you…."

Nick looks in her eyes. Without looking away he reaches over and kisses her. The kisses become more intense and he looks at her and says "Catherine, you have made me the happiest man in the world. This is more than I ever could have wished for."

She smiles and says "Let's go home."

He nods and says "We have to tell Lindsay. She is going to be blown away."

Catherine smiles and says "That is putting it mildly."

They smile at each other and drive in relative silence. Catherine starts to say something when she hears her cell phone ring. She smiles as she sees that it is Sara. She picks up and says "Hi Sara!"

Sara smiles and says "So!! How did the doctor's visit go!!?"

Catherine smiles and says "Well. It went well."

Sara kind of looks at the phone and finally says "That was cryptic! Come on Cath! I want details!!"

Catherine laughs and says "Well, it was definitely informative!"

Sara groans and Catherine laughs. She is being intentionally evasive with her friend. She is not quite ready to share her secret yet. She smiles and says "Listen, how about if you and Grissom come over for dinner tonight! You are both off. I will tell you then!"

Sara agrees and hangs up the phone. She runs into the kitchen and says to Grissom "We are going over to Cath's and Nick's house for dinner tonight! No arguments!"

Gil laughs and says "I wouldn't dream of it. What's the occasion?"

"Well, Cath went to the doctor's today and apparently she has some big news for us!"

Gil laughs and says "I wonder what it is?"

Sara laughs and goes to get ready for dinner. Gil watches her and smiles as she goes into the bedroom…..
