A/N: THANKS TO THOSE WHO REVIEWED!!!!

Catherine immediately pulled Sara inside, grabbing Sara's bag with her other hand as she closed the door. Placing it next to the door, she turned back towards the brunette. Sara was trembling, and her eyes were swollen and red. Catherine gaze swept her body, and she noticed that Sara's stomach had a slight bulge. She really was pregnant.

"He's back, isn't he?"

Sara finally spoke, and her voice was shaking. Timid. Vulnerable. Sara was scared.

Catherine nodded slowly, and Sara herself nodded. There was silence again for a while, before she spoke again.

"How… how is Nick?"

Catherine gestured towards the couch, and Sara gratefully took a seat. Catherine joined her, offering her a drink, which she politely refused.

"So?" Sara asked again. Catherine let out a long sigh. Should she tell Sara the truth? That Nick was suffering without her?

"Honestly, Sara," Catherine started. "Nick hasn't been the same since you left. You took a part of him when you went. You needed each other so badly, and you just left him. How do you think he is?"

Sara's eyes were wet, and Catherine could tell that Sara was hurting. Really hurting. She reached an arm out, and patted her on the shoulder.

"There's also the latest kidnapping…" Catherine added, and slowly trailed off. Sara eye's widened at the mention of it, and her hands twitched in her lap. "That's bound to hurt him some more…"

Sara nodded, and one of her hands came to rest on her stomach. Catherine raised an eyebrow.

"So why are you back?"

Sara looked at her again. "I just… I don't know."

"You going to see Nick?" Catherine questioned. Sara looked away.

"I don't know if I can."

"Why not?"

Catherine voice was soothing. She didn't want Sara to become defensive. That was the last thing she wanted.

"I don't want to hurt him again…"

Catherine gave her a small smile. "Sara, you are hurting him more by staying away from him. Plus…" She gestured at the brunettes stomach. "He'd be so over the moon about your pregnancy… this is exactly what the both of you need."

Sara's eyes flashed angrily. "She can't be replaced."

"Who?" Catherine asked innocently, despite the fact she knew exactly who Sara was talking about.

"Emily…"

Catherine leaned forwards again, looking deeper into Sara's eyes.

"Sara, I guarantee they'll be tough times…" she whispered. "And I guarantee that at one time or another, you and Nick will want out. But I also guarantee that if you don't fix this now… you are going to regret it for the rest of your life."

A few tears leaked out of Sara's eyes, and for a minute, Catherine thought she had gotten through to her. But after that minute, Sara's eyes hardened.

"Maybe it was a mistake coming back here," she mumbled. "Maybe I should just leave."

"No!" Catherine said. She wanted Sara to stay. The longer she stayed, the more Catherine could change her mind. Set her straight. Make her go back to Nick.

"It's alright," She told Sara. "You can stay here."

Sara finally smiled. Not her full 1000-watt smile she usually possessed, but a smile non-the less. It was a start, at least.

"Thanks…"

Sara stood up. "You can't tell Nick," she said. Catherine nodded reluctantly.

"I promise."

The layout room was empty except for Nick and the box of evidence from the 'Babysitter' case. It had been 2 hours since he had sat down with it, and he still hadn't found anything. Not that he was surprised. So many people had been through the case file, and they had not found any leads.

Nick just wanted to make sure they hadn't overlooked anything. Anything.

His hands stilled on Emily's file. He wasn't supposed to look at this file, and his hands trembled slightly as his fingers traced Emily's name.

Just because he couldn't look at the file, didn't mean he couldn't use things from it.

The dance teacher had seen the Babysitter. Well, not the actual killer, but the killers car. Of course it had been followed up, but nothing had come from it. Sara's car was not uncommon. There were over 100 registered in the greater Las Vegas Area.

The traffic camera's! Nick suddenly thought. They had played a small part in his own rescue. Maybe, just maybe, a car similar to the description the dance teacher had said could have driven through the traffic cameras.

But as Nick stood up, he suddenly remembered something else.

"I saw her get into her Mom's car! It was your car! Emily just got in! I thought it was her Mom! It was the same car…"

The killer had relied on Emily's resemblance of the car to lure her. Forget candy. This person used cars.

Was it possible the killer chose victims based on the cars he could get his hands on? Did he have access to many different cars?

Was Emily randomly selected because the killer could get a hold of the same car Sara drove?

What kind of person could get hold of many different cars?

Quickly, Nick made his way through the lab, and found a computer. Logging on, he quickly typed in Melanie Banks' details. And the brand of her car.

Melanie owned a Porsche Boxster X.

With a flurry of fingers he did an area search, looking for the same brand of car in the Las Vegas area.

There were only three, besides Melanie's. An uncommon car indeed. But as Nick glanced at the list, he realized it was unlikely that the killer's car was listed there. Although he followed all the other three names, it wasn't likely. A 73-year-old man owned one of them, and his car had been impounded when he had a heart attack a week ago. Another to a successful businesswoman, and the other to the 16-year-old daughter of one of Las Vegas's casino owners. None of them had connections to anyone who fit the profile of the "Babysitter".

But maybe it was possible that the car was unregistered.

Surely it wouldn't be hard to find an unregistered car…

Flipping open his phone, he made a call to Grissom. He reached voicemail. Angered, Nick tried Brass, and reached him.

"Brass? This is Nick. I need you to keep an eye out for a Porsche Boxster."

"Got anything else to tell me about the car? That's not much to go on."

"Its most probably unregistered," Nick told him. He heard Brass sigh.

"I'll do what I can."

The dial tone assaulted Nick's ear.

He couldn't just wait for Brass to find that car! That little girl was being hurt now! He couldn't just sit here and wait for someone to find the car, or worse, her body.

His mind set, he left the lab, and got into his car.

He would find that car himself, and he would find that little girl.

Even if he had to do it all by himself.
