A/N: Thanks for the reviews!

I felt the need to go back in time, so you all know what exactly happened to Sara.

Oh and this should be a long chapter :D

60 Hours Earlier

"Hey, Sara," called Greg as she entered the locker room. Fighting the urge to sigh heavily, she'd just worked a double and was definitely not in the mood to talk to anyone, she smiled at the lab tech and grabbed a few things from her locker. "Hey, uh, me and the guys were gonna grab a bite to eat at the diner, you know. If you wanted to come," Greg offered, shrugging into his coat. Sara turned to him slowly, showing a soft smile, "I'm pretty beat, Greg, I'm just gonna head home and get some sleep," she finished changing her hike boots for a cleaner pair. Greg wished her a good night and was on his way.

As soon as she shut the door behind her, Sara rested her head against the wheel and closed her eyes, intending on staying there for just a few moments. However, when she opened her eyes again, the pre-dawn light was now a burning orange. Checking her watch, she cursed to see it was passing 8:30. She started up the engine and began to drive home, unaware of the dark vehicle following close behind. The welcoming green light turned an angry shade of red and she had to slam on the breaks to avoid hitting an oncoming cars. When she noticed a black SUV following suit, she checked the front seat in case it was one of the guys. The pucker between her eyebrows appeared as they automatically pulled together in confusion, there was no one sat in the car even though it had stopped just moments before she'd looked.

She swung her head back around to check for anyone, but a startled scream echoed through the cab when she noticed a tall figure stood outside her door. His thick black hair hung just below his jaw and was parted down the middle, curving round his face which was deathly pale and menacing. Before she could lock the doors or step on the accelerator, he was bending the handle upwards, allowing himself access to the car. Her eyes wide with shock, she climbed backward over the gear shift and hurtled herself through the passenger door. The cold pavement scraped her hands and elbows, but the pain went unnoticed, shadowed by her growing fear. She picked herself up and sprinted across the road, which was deserted despite the hour. His footsteps were close behind her, but she didn't look back, stretching her long legs ahead of her to cover the distance quicker.

She found herself following the curving pavement, leading toward a block of houses. Relief washed over her when she noticed a few people exiting their houses, smiling and acknowledging each other. She swallowed hard, building up for a scream, but before she could make a sound, strong arms were pulling her back and into an alley.

The man pinned her against the wall and inhaled deeply, for what reason she didn't know, but his eyes drifted closed. She took the opportunity to swing at him, but he must have sensed her move, because his grip tightened leaving her defenceless. "Hold still," his voice swirled around the small space and she squirmed despite his protests. He let out an angry snarl and bit her left palm, shocking her both from the intense pain and unexpectedness.

He might as well have dragged a knife across the skin. Glancing down at her hand, she saw there was a deep gash dripping with blood. The man licked his lips and she propelled into further terror, drawing his attention back to her face. His eyes were unfocused and his nostrils flared slightly. Her gut instinct was to scream, but something about him made her feel incredibly vulnerable and, considering he'd guessed her other moves she didn't act on it.

He removed his long, pale fingers from her arms and took a step back, drawing in deep breaths and keeping his eyes averted from her hand. His voice was low and breathless, like he was almost in pain. "I'm sorry... I'm so sorry... I'm just so thirsty... I can't control myself sometimes... I don't like hurting people... And now... Now, you're..." Sara was utterly confused by his words, he was sorry? Sorry for what? Chasing her? Biting her? Scaring her half to death? He dropped his eyes to the floor, "I'm sorry Sara... I'm sorry, I'm sorry, I'm sorry." How did he know her name? He repeated the words like a mantra, keeping his eyes on his feet.

Before she could say another word, her body collapsed with exhaustion and her eyes drooped.

TBC...

Review Please :)

A/N: I hope this clears stuff up for you, by the way just like Grissom and the guys don't remember, Sara doesn't. Yet.
