She wasn't quite sure where she was, but judging by the length of the drive, Sara figured they were nowhere near the hotel.

Her foot was still aching, though she'd managed to stop the bleeding by tying a cloth to it.

The room they were now in was small. It reminded Sara of the dorm room she'd lived in during college. There were some semi-transparent drapes on the windows and all the furniture was cheap and dirty.

"Ally…why?" Asked Lauren and Sara noticed her pain seemed to have escalated.

"Don't 'Ally' me!" Allyson replied bitterly as she looked through the curtains. "You know perfectly well why. It's your own fault. Yours and Carl's!"

"Carl?! Allyson, that was 9 years ago!"

Allyson didn't seem to care "You caused my depression, you cost me the past nine years and you're responsible for my baby's death."

Lauren knew that to some extent this was true. Looking back, she couldn't help regretting her actions. She'd been 17 at the time and Carl 23. Her sister, 21, and he were to be married, but at the rehearsal dinner, Champaign, margaritas and other sneaked-in drinks had lead to Lauren and Carl being found together in the linen closet; by Allyson. Devastated, Allyson had fallen into a terrible depression that ultimately led to the loss of her unborn child and her commitment to a psychiatric clinic.

"The doctor thought I was cured! He let me go home. But, as you're about to find out, you never get over loosing a child." There were angry tears in her eyes now "when that letter arrived, you told us you were pregnant and, like nothing had ever happened, invited me to come along to celebrate it. No therapy could cave stopped me seeking revenge!"

Lauren's pain had spiked with the tension of the situation and she was clutching her stomach as tears continued to flow down her cheeks smudging her flawless makeup.

Allyson either didn't notice or didn't care. She merely reached into a drawer and pulled out an ultra sound which she threw at her sister.

Lauren simply brushed it to the floor, tears dripping off her chin.

Sara, who'd been sitting on the floor picked up the fallen image and examined it.

"That would have been your nephew." Allyson spoke slowly as she held Lauren's head, forcing her to look at the picture.

Sara recognized the image immediately, she'd processed six identical ones in the last week. A finding that would normally have solved a case and made her happy was now making her fear for her life. This woman had mercilessly taken the lives of 10 innocent people and had made it perfectly clear that four more were on their way. Did any one know here they were? Would they be able to get to them in time? Her thoughts were racing but the one that hit her hardest was the idea that she might never see Grissom holding their child.

Having processed everything they could without their kits, Grissom and Catherine sat down at their table waiting for Nick and Warrick to return.

"She'll be fine, Gil…" Catherine tried to reassure him as he stared at Sara's full glass of champagne.

"It took me so long to admit how I felt about her…too long. Now she's gone…" His voice was shaking at Catherine didn't know what to do to make him feel better.

"Gil, she'll fight her way back, you know she will."

Again he didn't seem reassured "No she won't, Catherine. Sara's almost five months pregnant. She won't risk it. We have to find her." His voice was shaking more and he sounded desperate.

"It'll be fine, Griss. Pregnant, huh?" She smiled as Grissom took a sip of the champagne "You? A father? Don't take this the wrong way, but I never pictured you as the daddy type."

He smiled "To tell you the truth, neither did I. But now, I was actually looking forwards to it."

He knew he was coming off very pessimistic as he used the past tense. But the criminalists in him told him to prepare himself for the worse.

"Don't talk like that, Gil." She would have continued comforting him if Warrick and Nick hadn't just walked in.

Sara knew they hadn't been there for long, but it felt like they had. Allyson had said she wouldn't kill Lauren. She would wait for Nick, "the perfect CSI" as she'd called him, to turn up. She'd then kill him and then her child leaving Lauren with nothing like Lauren had left her. As for Sara, Allyson had decided to wait. She was going to do it, no doubt there, but she thought that to really make Lauren suffer, all the deaths should happen at the same time to make her feel as guilty as Allyson had felt depressed. After all, if Lauren hadn't done what she did to Allyson, Sara would still be safe.

Right then, Allyson was in a different room. She'd locked Sara and Lauren in the small bedroom and was now sitting in the living area waiting for Nick.

"Are you alright?" asked Sara as Lauren clasped her stomach in pain.

"No…"Breathed Lauren as tears tumbled down her cheeks "I…I need to get to the hospital."

Sara tried to comfort her. However, all Lauren could do was cry. Allyson was right. All the murders Nick had been working on were her fault. Sara was going to die and it was her fault. Nothing anyone could tell her could ease the guilt.

After processing every inch of the room, the CSI's had taken the evidence back to the lab and got on with analyzing it.

Greg was in the lab analyzing the blood samples. Catherine and Warrick were looking at the surveillance, Grissom was with Nick in the other lab trying to find a match for the prints they'd gotten off the window.

When they finally got a match, disappointment took over hope. There was no perp. The prints from the window had matched Allyson Watson's. They'd known all along she'd been in the room, so finding her prints wasn't a significant finding. What was a significant finding was the fact that Allyson had a record. Nick knew Lauren didn't enjoy talking about her family, but a sister with a record fro violent behaviour was something he'd expected to know about.

"Well, I guess…that gives us a suspect" Grissom said as he printed the sheet.

Nick nodded "but why would Allyson kidnap Lauren? And Sara?" He took the sheet from grissom and looked puzzled at it.

"I've no idea, Nick. But we could ask her parents, maybe they'll know something." Grissom said raising his eyebrows as Nick picked up the phone.

Minutes later, Catherine informed them that the surveillance tapes showed Allyson driving the get away car and all doubt that Allyson was the perp vanished.

Once Lauren's parents arrived, Grissom and Nick began questioning them.
