Catherine stood in the middle of Nick and Sara's living room with a huge grin on her face. "It explains a lot actually."

Sara looked surprised. "What do you mean?"

Catherine approached the subject carefully. "Well, when I was pregnant with Lindsey, I didn't really start showing until I was about five or six months along."

Sara raised an eyebrow. "Five or six months?" She glanced down at her abdomen which was already starting to bulge slightly. "I'm only three months into this." Her face reflected a little panic as she looked over at Nick. "I'm going to be as big as a house."

Nick did his best not to laugh and glanced at Catherine who shot him a 'tread carefully' look. He walked over to Sara and placed his hands on her shoulders and looked into her eyes. "Honey, it's physically impossible for you to be as big as a house."

Sara furrowed her brows. "You know, you're lucky that I love you so much because, you're not funny."

"Sara." Nick's tone was serious. "I know that I'm very lucky that you love me, I love you too."

She smiled in spite of herself.

He smiled too. "I don't care what size you are, Sara. You're carrying our children and I love you." To emphasize his point, he leaned in and kissed her softly, smiling as he pulled away. "Now go spend some money and buy yourself some new clothes so I can have my jeans back."

Sara smirked. "What if I want to keep your jeans?"

He raised an eyebrow, but before he could say anything more, Catherine interrupted. "Sara, by the time we're done shopping you won't want to wear his jeans. You're going to be one hot pregnant lady."

Nick glanced over at Catherine and then grinned at Sara. "She already is."

A faint blush crept into Sara's cheeks.

"I had no idea that there were this many cute clothes for pregnant women." Sara looked in the mirror as she took in her appearance.

"Here, I've got more for you to try on, and then we can go grab a cup of coffee." Catherine handed her another pile of clothes.

"I can't have coffee; the doctor told me I couldn't have caffeine." Sara groused.

Catherine smiled. "Actually, one cup a day won't hurt, but you're right that you can't drink it the way you're used to."

Sara hung the last of the garments up in the dressing room and smirked. "I think I'd rather spend my caffeine allotment on chocolate."

"Smart woman." Catherine responded. "Now try those on."

Sara emerged a few minutes later with a smile on her face. "I think I've just found my new favorite pair of jeans."

Catherine chuckled. "I told you that you wouldn't want to wear Nick's jeans after we got done shopping."

Sara smirked. "I don't think he's getting them back any time soon. It's too much fun to tease him with them."

Catherine let out a deep throaty chuckle. "Sara, you never cease to amaze me."

Sara smiled. "What? I'm not allowed to seduce my husband?"

Catherine just laughed. "I didn't say that. You've just never struck me as the kind of woman that could keep up with Nick if you know what I mean."

Sara deadpanned. "You obviously don't know me very well."

Catherine chuckled. "You're right, I seriously underestimated you."

Sara looked at Catherine with a devilish grin. "So, do you think they have lingerie in this store?"

Catherine laughed again. "Don't worry, we'll find something that'll have Nick begging for mercy."

When Nick arrived at work that night, he tried to tone his smile down, however, as soon as Warrick walked into the break room and saw Nick leaning up against the counter sipping his coffee, he knew something was up.

He nodded at Nick as he poured himself a cup of coffee. "Hey, man, how's Sara?"

Nick couldn't restrain his grin. "She's amazing."

Warrick chuckled. "Do you two realize how sappy you both sound?"

Nick shook his head and continued grinning. "We got an ultrasound today."

"How did that go?" Warrick asked taking a sip from his coffee.

Nick pulled several printouts of the images from the pocket of his shirt. "Want to see the baby?"

Warrick's eyebrows shot up as he looked at the first image. "Hey, you can actually see features."

Nick nodded. "Yeah, the new technology is pretty amazing."

Greg sauntered in. "Whatcha looking at?"

Warrick glanced up. "Ultrasound of Nick and Sara's baby."

Nick tried to suppress a smile.

Greg glanced over and smiled. "Oh, hey, your doctor must have one of the newer ultrasounds."

Nick nodded. "Yeah."

Warrick studied the image for a moment and then glanced at Nick curiously. "Hey, I can see the baby there, but what's that?"

Nick took a sip from his coffee to keep his smile at bay.

Greg glanced at the image Warrick had referred to and glanced up at Nick with wide eyes.

Nick just lifted both eyebrows and smiled.

Greg just grinned.

When Warrick looked at the next image his jaw dropped and he looked at Nick. "Is that what I think it is?"

Nick nodded, unable to restrain his grin. "Yeah, that's exactly what you think it is."

"Two?" Warrick wanted to clarify.

Nick nodded. "Yeah, two."

Grissom chose that moment to walk in. "Two what?"

No one said a word.

Grissom looked at the three men over the rim of his glasses. "Two what?"

Nick took the image Warrick was looking at and handed it to Grissom. He couldn't help but grin. "Sara had an ultrasound today. We're having twins."

Grissom glanced at the image and then up at Nick, his mouth just hanging open.
