A/N: See chapter one. I really have nothing excessively witty to say, so I'll just recap what's happened with the story. Oh, and I'm going to put a little GS backstory in here that I have absolutely no basis for, but what the hell. Just for fun I'm going to do a little flashback that's a totally random tangent. I was going to put this in a separate story but since I've worked out how to smoothly put it into this one, I see no reason not to. Plus it gives me a great basis for a little Grissom/Sara/Nick triangle/angst. Woohoo.

Previously in It's a small, small world (hey, I came up with a title! Yay for me)

Greg's little sister Anna came to intern at CSI. She exposed Sara's feelings for Nick in chapter one. In chapter two, Anna and Greg's mother died, and Nick found out that Anna was his daughter. Boy, how's that for drama? Wow. I don't think I can even stand it. Anyway, here's some more of my lovely story.

Chapter Three: Telling Anna

Greg and Nick sat silently in the DNA lab, each lost in their own thoughts. Greg had finally found out who Anna's father was. He just didn't expect it to be Nick. "I don't know how to handle this." Greg rested his head in his hands.

"I'm totally clueless too." Nick heaved a sigh.

"I don't even know how to tell Anna." Greg shut his eyes.

"Tell me what?" Neither of the two men had heard Anna step into the glass-walled DNA lab. "Tell me what, Greg?" She asked more sharply.

"Anna, you have to not freak out." Were the first words that came out of Greg's mouth.

"Hey, with a preamble like that, of course I won't freak out." Anna's usually hazelish eyes were beginning to cloud. That's when Greg saw the resemblance. The hair, the eyes, the facial features, even the way she stood. She was definitely Nick's daughter. Greg still hadn't spoken. For the first time in her life Anna swore at her brother. "Dammit Greg, what the Hell is going on?" Anna snapped.

"Anna, you're not going to like what we have to tell you." Nick said softly.

"What do you have to do with this?" Anna rounded on the Texan.

"Trust me, he has a lot more to do with this than you think." Greg's gaze was tight and weary.

"WILL THE BOTH OF YOU PLEASE JUST TELL ME WHAT THE HELL IS GOING ON?" Anna yelled.

"Anna, you'd better sit down." Greg offered his seat to Anna. Obligingly, she took it. "Anna, uh...we found out who your dad is."

Anna's expression changed. She wasn't going to Harvard just because she was pretty. "Oh. My. God." Slowly she turned to face Nick. "You're my father, aren't you?"

Nick just nodded.

"Oh my God." Anna ran to the trashcan and promptly threw up. "Excuse me."

And that was why Sara found Anna huddled in the bathroom, crying. She was even more worried when Anna grabbed the trashcan and vomited. "Anna, what's wrong sweetie?" Sara flew to the eighteen-year-old.

"Oh God." Anna moaned.

"Anna, tell me what's wrong." Sara's voice was commanding yet gentle.

"Oh God. I can't believe this." She mumbled.

"What can't you believe, Anna?"

"He's my dad." Anna stared at Sara, her eyes wide and hollow.

"Who?" Sara's eyes narrowed in suspicion.

"He...here..." Anna was gasping now.

"He works here? Is it Grissom?" Sara's voice rose.

Anna shook her head vehemently. "Not Grissom. Nick. Nick is..."

Sara got it. "Nick is your father?"

Anna moaned again and reached for the trashcan.

"Oh, you're not well." Sara helped Anna off the floor and dragged her to Grissom's office. Sara followed Anna into the room and flipped the lock. "Grissom." She said.

Grissom looked up from his work. "What do you need, Sara?" It was only then that he noticed the intern's facial expression.

"Grissom, Nick is Anna's father."

Grissom's jaw dropped. "How is that even possible?"

This time Anna answered. "Mom was a professor. At the University of Washington. She did a lecture on criminal law at University of Texas at Austin."

Grissom was beginning to understand. Anna's mother had been in the same situation he'd been in with Sara.

"My mom had an affair with one of the students at the seminar. A few months later they found out she was pregnant with me. Mom never said who my dad was and then yesterday morning she died. I just found out that Nick-" She couldn't even bring herself to finish the sentence.

"Nick is her father." Sara said quietly.

Grissom put his forehead against a palm. "Alright. Anna, I want you to take the rest of the afternoon off. Go get yourself some coffee and something to eat."

Anna nodded.

"If you need some time off, just let me know."

Anna nodded again and stood up. "I'll be back tonight."

"Good." Grissom smiled. Anna left but Sara stayed behind.

"Boy, what does this remind you of?"

"Sara, Tyler was better off with a family that was around. He never would've grown up sane with us. Besides, you were only a college student, you weren't ready to be a mother."

"I know." Sara sat down. "You know, sometimes I think that maybe I'd like to see Ty. Call him up. Have lunch."

"I understand." Grissom nodded. "I'm not sure that'd be the best idea."

"Why not?"

"Because, Sara, Tyler would only be fifteen."

"Sixteen." Sara corrected him. Tyler's birthday had been just over a month ago. May seventeenth. The only day Sara ever needed a day off from work was her son's birthday.

"Still, Sara. I don't think you should do it."

Sara stared mutely at Grissom. She'd loved Grissom, she supposed. When she'd invited him out to dinner she'd wanted to discuss their lives and maybe getting back on track. Getting together again and then trying to find Tyler. Sara knew he lived somewhere in Vegas. She even knew that she and Grissom had visitation rights if they so chose to seek out Tyler. After what seemed like an eternity Sara looked at Grissom. "Do you remember?" She asked softly.

Grissom let out a short bark of laughter that was halfway between bitter and resentful. "How could I forget?"

Sara was so excited. She was twenty-one and in love with the world. She had a little piece of plastic in her wallet that said she was old enough to legally swallow alcohol. She was entering her senior year at Harvard. She'd finally put that scumbag Mike Hanson in jail for raping her, just like he deserved. Sara was on top of the world, in love with the world, and just plain happy to be alive. Sara opened the door to McKenzie Hall. Though she loved physics, what really drew Sara was forensics. Ever since she'd started to read about it last semester, Sara had been totally fascinated by forensics.

"Now Sara." Her mother had gently chided her. "Don't forget what happened with ballet lessons. And piano." Sara remembered with a smile. Ballet had lasted a month before Sara didn't like it anymore and piano had only lasted three weeks.

"Look, there's a seminar this September." Sara had argued. "I'll take the course and we'll see if I like it."

Sara's mother had agreed to that plan so Sara had enrolled in the class. And here she was, on the last day of the seminar. Every single lecture she'd listened to so far was fascinating and Sara was surer than ever that she wanted to pursue a career in forensics. This was the last lecture of the seminar. Sara strode into the class and took a seat in the second row. She didn't want to seem too eager by sitting in the very front, but she wanted to seem at least mildly interested. Sara glanced at the lecture schedule. This lecture was supposedly on entomology. Gil Grissom. Sara considered the name. She liked it. As soon as the lecture hall had filled up, a man carrying a brown leather briefcase strolled into the room. Sara's breath caught in her throat when she saw the professor. He was in his thirties, Sara was sure. He had curly brownish-black hair and the most startlingly blue eyes Sara had ever seen. He wore wire-rimmed glasses and a serious expression. She observed his style of dress. "You can always tell what a person is like by the way he or she dresses." Sara's roommate, Amanda, had told her when Sara was going through her closet. Slacks. Sara noticed. Gil Grissom wore khaki slacks and a black golf shirt. He had strong, tanned forearms and his chest was muscular. Sara kicked herself. This was the professor. Sara listened raptly to the lecture and was disappointed when it was over. Sara told herself she was ninety-nine percent disappointed that the actual lecture was over and only one percent disappointed that she was leaving the presence of Gil Grissom.

"Excuse me, do you have a question?" Dr. Grissom looked up at Sara.

Sara blushed. "Actually, yeah. I was wondering if I could take you to lunch and pick your brain."

Grissom was always eager to impart his knowledge of forensics and entomology onto young students. "Sure." He nodded. "Just let me grab my coat."

They sat in Speedy's Deli, Sara munching on a hamburger and Gil devouring a tuna melt. "I don't think I could ever be a vegetarian." Sara scarfed the hamburger down. "I couldn't live without my hamburgers."

Gil smiled. "So, what do you want to know about forensics?"

The two talked for hours, wandering to an ice cream parlor to get desert. "You like chocolate chip cookie dough too?" Sara eagerly licked her cone.

"It's been my favorite since I was five. My mom used to make it the good way though. She made the actual dough and mixed it in with vanilla ice cream."

"Mmm...sounds good." The two strolled in comfortable silence until they reached Grissom's hotel. "I guess this is goodnight." Sara smiled sadly. She'd had such a good time with Dr. Grissom. Whoa. She thought. This is your professor. Let's not get too friendly.

But still she found herself accepting Gil's invitation up to his hotel room. They had coffee and discussed forensics only a little more before their attraction was too hard to fight. In a matter of minutes they were both under the covers of the bed.

Sara knew she shouldn't have continued, but her lust for him was too strong. They were lovers for three months before it all went wrong.

Sara was sitting on a horrible examining table in her doctor's office. "No." She pleaded. "No, I'm not old enough to be a mother." Her eyes had lost their fire. When she'd told Grissom he'd offered to marry her, but Sara had refused. "I'm not ready to be a mother. And I don't think you're ready to be a father." She'd told him. "I don't want to, but it'll be the best thing for the baby if we give him up for adoption."

And so another six months later when Tyler Michael Sidle-Grissom was born Sara refused to hold him, for fear she would get too attached and not be able to give him up. Sara had considered abortion, but it wasn't fear to the fetus inside of her. It had never done anything to her. Sara had always been a staunch believer in abortion and a woman's right to choose, but when the time had come, she'd chosen to put the baby up for adoption. Gil had been called, but Sara had refused to let him be with her while she birthed their baby. He'd left.

Seven years later he'd called her. The most contact they'd had since she'd refused to let him be with her when she was in labor. He wanted to know if she would come to Las Vegas to help him with an IA investigation. How could Sara say no? She still loved him and she knew it. So she was on the next plane to Las Vegas and she made her way to the hotel where Grissom was supposedly. Sara pushed away the bad memories of giving up her son and Grissom and focused on how good they'd been together. She was happy. It was later that she noticed the dark haired Texan and his flirtatious way. Slowly Sara had been drawn away from Grissom and towards Nick.

"I remember it." Grissom repeated. "Oh how you screamed at me when you found out you were pregnant. Oh how my mother screamed at me."

Sara laughed. "Gris, I don't care what you say. I'm going to find Tyler, and I'm going to tell him what happened." She caught the look on Grissom's face. "If it's okay with the parents." Sara rolled her eyes. "Have a good day Grissom."
