Instead of heading home, Catherine drives straight to Nick's house. She feels as though she is on auto-pilot. She remembers nothing of the drive there. When she pulled into his driveway, she sat there for a few minutes. Until she started getting looks for his neighbors, then she decided that she needed to go inside before one of them called the police.

She took a deep breath and knocked sharply on the door. Nick answered and he was absolutely stunning. He was wearing boxers and no shirt. Catherine was able to smile and say "I hope you don't answer the door like that for everyone?"

Nick laughed and said "Nope, just for the beautiful women."

Catherine laughed and stepped forward to hug him tightly. Nick got a concerned look on his face. Something was wrong. He could sense it. He led her over to the couch and sat down with her. He looked deep into her eyes and smiled as he said "What's wrong?"

"Who says anything is wrong? Why can't I just come and see the most handsome man in Las Vegas?"

Nick's brow furrows and says "I can read you like a book Cath. Come on, this is me your talking to. Did someone at the station find out about us and…."

Catherine shook her head and said "No, not yet."

Nick held her face in his hands and said "Come on Cath, talk to me."

The tears that had been present lately threatened to break thru. Nick looked at her and said "Come on Cath! Talk to me baby!"

She put her face in her hands. How had she gotten into this situation? She was a grown woman and should have known better. It wasn't like it was totally unexpected. These things happen, but she wasn't sure how Nick was going to react. She looked up at him. Her face was bright with tears and finally she took a deep breath as she said "I want you to know that I love you. So very much."

Nick is getting worried at this point and says "I love you too."

Hearing those simple words Catherine smiles and says "I hope you know I didn't plan this. It was a mistake. I never thought it would happen. I…."

Nick it totally confused at this point. He looks at her blankly and says "You've lost me Cath! What are you talking about?"

She is finally able to manage a small smile and says "I'm not doing this very well. Am I?"

Nick shakes his head and says "No, your not."

She takes a deep breath and starts over again "Well, you know I haven't been feeling well lately. So, I went to the doctor, and…"

"Are you okay?" Nick's voice was filled with concern. Catherine smiled and said "I am fine. At least I will be in 8 months or so."

Nick takes a minute to let it sink in. Finally he looks at her and says "Are you saying what I think you are saying?"

Catherine nods her head and says "Yes. I'm pregnant."

Nick lets out a whoop of joy and picks her up and hugs her tightly. Suddenly he gets a concerned look on his face and says "I didn't hurt the baby did I?"

Laughing Catherine smiles and says "They are pretty tough at this stage."

Nick sits on the couch with Catherine. His hand rests on her still flat stomach and he whispers softly "A baby. Wow."

He finally looks up at Catherine with a smile on his face and tears in his eyes. She looks at him and says "I didn't mean to make you cry Nicky!!"

"These tears are from joy Cath! You have just made me that happiest man in the world. I love you Catherine! In fact wait right here."

She watches as Nick goes in his bedroom. We hear the opening and closing of a few drawers. Finally Nick emerges from the room. He walks into the room and over to Catherine. She smiles up at him. Instead of sitting next to her on the couch, he gets down on one knee and says "I love you Catherine Willows. Will you marry me?"

Catherine is speechless. So much is going thru her head. She looks at him and before she can speak he says "I know you are probably thinking it is because of the baby."

This gets a nod from Catherine. Which causes Nick to chuckle as he says "It's part of the reason. I actually bought the ring before tonight, yesterday in fact."

Once again Catherine is speechless. She simply looks at him and says "Yesterday?"

Nick nods and says "Yes, yesterday."

She finally finds her voice and is able to say "Ask me again."

Nick opens the box and looks at her and says "Catherine, I love you. Will you do me the honor of becoming my wife?"

Catherine smiles at him and nods as she says "Yes!"

Nick is speechless and finally says "Alright!!"

Catherine laughs and smiles as she holds out her hand. He takes it and puts the ring on her finger. She smiles and looks at the ring. She pulls him close and kisses him deeply. Afterwards she says "Well, I guess we are going to have to tell Eickle!"

Nick groans and says "Do we have to? I mean we could keep it a secret!"

Catherine laughs and says "It's going to be a little hard to keep the baby a secret. I mean I am going to start showing soon and…"

Nick smiles and puts his hand on Catherine's stomach. He looks at her and says "That could mean that we won't be working together anymore."

"But we will be living together, which would be even better."

Nick smiles and says "So, should we go tell him now, or later?"

Catherine laughs and says "Well, there is no time like the present."

"Why do I feel like I am being led to the gallows?"

Catherine laughs and says "Cheer up Nick! It won't be that bad."

They both stand up and walk outside and head over to the lab.
