There was something different about her; Jim just couldn't put his finger on it. He knew what it was, but he just didn't know. She would have good days and bad days, but the twinkle in her eyes was a constant. It had been bugging him for weeks until, finally, Jim knew what it was. He'd seen it before, but it was such a long time ago. Now it was Catherine who had it, the 'glow'. After realizing what was different about her, Jim decided to wait until he had confirmation; confirmation that he would receive today.
"Hey Jim?" Catherine said from his office doorway.
"What do you need Cath?"
She closed the door behind her and sat across from him. "I have to tell you something."
"No shit."
Catherine gave him a look. "I'm being serious."
"So am I." Jim folded his hands on the desk. "How long did you think I wouldn't notice?"
She grinned. "Oh, I don't know…until I threw up at a crime scene maybe."
"You insult me by underestimating me." He leaned back in his chair. "How far along are you?"
"Almost 8 weeks."
Jim nodded. "Can I ask you a serious question?"
Catherine frowned. "Uh…yeah."
He spoke in a low whisper. "Is it mine?"
Jim hadn't heard her laugh like this since her 'bachelorette' party. "No." she managed to say after catching her breath.
He pretended to be disappointed. "Oh." Jim smiled at her. "If you ever need anything…go to Gil."
Catherine snorted. Standing up, she made her way to the door but when she turned the doorknob, Jim asked her another question.
"Is it Gil's?"
Her laughter could be heard all the way outside the building.
In case you're wondering...Gil Grissom is not the father. :)
