Catherine, Nick, and Sara walked into the break room. They were the first ones there and they made their way over to grab coffee.

Catherine wrinkled her nose as she smelled the small amount of coffee left in the pot, "I think this swill is left over from day shift."

Just then Greg breezed in, "Never fear, I've got a new bag of coffee. It's a special blend of South American beans with a hint of deeper rich African tones."

"If you can guarantee we'll never be without your coffee, I'll tell Grissom he needs to give you a raise," Catherine grinned at Greg.

"You're in a good mood, Catherine." Greg smiled at her. He looked at Nick and Sara who just smiled at him. "Your heads look better today."

"Thanks, Greggo." Sara commented, "Anything new on our foreign DNA?"

"I'm glad you asked, Sara. No. But then I haven't been in the lab yet, so I haven't been able to recheck CODIS." Greg answered. "So, did you have fun partying at Catherine's?"

"Greg, we did not party at Catherine's." Nick raised an eyebrow at Greg as he spoke.

Sara gave him an amused grin.

"Just wanted to make sure I didn't miss out on anything." Greg continued as he made the coffee.

"Just in time I see." Warrick breezed into the break room.

"Hey, Warrick," Catherine greeted with a sly smile on her face.

Warrick took it in and glanced over at Nick and Sara. He looked back at Catherine and she raised an eyebrow with a sly smile. He smiled, knowing she'd fill him in later.

"Ok, Greg's special blend is ready for the tasting." Greg poured himself a cup of coffee and made his way to the table.

Sara grabbed a cup and poured coffee into it before handing it to Nick. She grabbed another and filled it up and handed it to Catherine. She grabbed a third cup and filled it before giving it to Warrick. Finally, she got herself a cup and filled it up.

The rest of the CSIs looked at each other and smirked before thanking Sara.

"Where's Grissom?" Warrick asked.

"Right here," Grissom walked in and got himself a cup of coffee before joining the group at the table.

"Got our assignments?" Nick inquired.

Grissom's eyebrows arched as he replied, "Yes, you and Sara are still on the Vargas case. Your head looks better. Catherine and Warrick, follow up the case you were working on yesterday. I'll provide back up wherever needed."

The group finished their coffee and then headed toward their respective assignments. Nick and Sara went to the evidence room to go over what they had collected from the scene once again and see if they could see anything new. They spread everything out in one of the layout rooms.

Each time one of them caught the other's eye, they grinned. After about an hour, Nick walked over and stood next to Sara. He cleared his throat.

"Hey, Sara." Nick smiled at her.

"Yeah, Nick?" Sara responded with a smile as she looked at him.

Nick grinned at Sara, "Would you like to go out on a date?"

A mischievous grin crossed Sara's face, "With who?" She traced the buttons on his shirt with one of her fingers.

Nick chuckled and grinned back, "Well, I don't think Mel Gibson is available, so I was hoping you'd go out with me."

Sara grinned flirtatiously, "I'll go out with you, Mr. Stokes, but on one condition."

Nick raised an eyebrow, "And what's that, Ms. Sidle?" He reached over and brushed a lock of hair behind her ear.

"No country music." Sara tried to stifle a laugh.

Nick tried to act hurt and suppressed a grin, "That hurts. Country music has a bad rap. But seeing as how I really want to take Sara Sidle on a date, there will be no country music on our date." His fingers caressed her shoulder.

Sara grinned at him.

Greg walked into the layout room, "I found something interesting you both might want to see."

Noticing that Greg didn't make and quips about their close proximity, and that he wore a serious expression on his face, Nick and Sara followed him without question down to the DNA lab.

"Since CODIS wasn't spitting out anything, I thought I'd take a different route. I compared the foreign DNA to our known DNA donors. It came up with something very interesting. The DNA belongs to someone who is related to Dr. Vargas."

Nick and Sara exchanged a look of shock and then looked back at Greg.

"And, someone related to Delia Herrera." Greg continued. "It appears that Delia Herrera is a first degree relative of Dr. Vargas, as well as a first degree relative to our DNA donor."

"Delia Herrera said she didn't have any relatives in this country." Sara had an expression on her face that was somewhere between confused and angry.

"I'll call Brass, you call Grissom." Nick replied pulling his cell phone from his belt and punching in the number for Jim Brass.
