"Foreign substance was…paint?" Sara said looking at the results in trace. "Yep; non-toxic," David Hodges of the trace lab said nodding. "So, kid's paint?" Sara said looking at him. "Most likely," he said heading back toward his workspace. Sara left the lab and caught up with Catherine.

"Catherine, foreign substance was kid's non-toxic paint," she said walking along-side her coworker. "Huh, well get this- we got a sample of sweat from inside the shoe, ran it through the computers. Got a hit," she said handing Sara a paper. "Fred…Bondoza?" she said trying to pronounce the last name. "Yeah, Brass is heading over there now," Catherine said taking the paper back. "Okay, I'll see you later," Sara told Catherine as the blonde-haired woman walked off.

Sara walked past the DNA lab and decided to check up on the new lab-tech. "Hey Monica, how's your first day?" she asked with a kind smile. "Fine," the woman said plainly. "Uh, is everything working okay?" Sara asked the woman. "Yes, fine," she said processing some samples. "Um…alright, well, see ya," Sara said walking out. The young lab-tech was holding a small vile and clenched her hand into a fist, making it shatter. Sara heard the glass break and turned around.

"You all right?" she asked her walking over to her. "Yeah, I'm fine," she said not wanting any of Sara's help. She grabbed a towel and dabbed her hand before cleaning up the glass. "Okay," Sara said nodding and walking out. Monica glared at her as she left.

The cases were going smoothly, Catherine and Brass had just helped put an end to the de-comp case and Sara was just going home for the night. She headed to the locker room to find Catherine inside, going through her own things. "Hey," Sara said to Catherine opening up her own locker. "Nice work on the case," she told her. "Thanks," Catherine said smiling and closing her own locker. "Take it easy, Sara," she said walking out of the room and leaving the lab for the night.

Sara nodded as the woman left and fell back against her own locker a little, rubbing her head. She had a sudden headache, not sure what had brought it on. She shrugged it off and closed her locker as she headed out for the night. Grissom, Nick, Warrick, and all the lab-techs had already left for the night- there weren't any cases. Sara felt a sudden jerk in her stomach and ran out of the room and into the bathroom, getting sick.

She walked out of the bathroom. She thought it just must've been something she ate, or maybe she had a bug. She walked past the DNA lab, but stopped when she spotted a figure inside. "Monica?" she said walking over to her. The young lab-tech said nothing. "What are you doing here, everyone else is gone?" she asked her. The lab-tech shrugged. Sara headed out. "Like my little surprise?" the lab-tech asked not looking up from the book in her hand. Sara stopped.

"Surprise?" Sara said turning around. "Yeah, slipped it in your lunch this morning," she said now looking up. "Wait a minute, you're trying to tell me…that you poisoned me?" she said blinking. The lab-tech just nodded. "Why would you-" "Oh, spare me," the young girl said walking out of the lab. "Couldn't you tell I never liked you from the start?" she said looking Sara in the eyes. Sara did get a bad feeling after shaking the girl's hand the first time.

"I changed my name. My brother was a suspect in a sexual assault case four years ago," she said on a more serious tone. "You used to be in San Francisco, so I had to go digging to find your new location," the girl said simply. Sara was a little freaked out that the girl had basically stalked her. "I have no more family, and the other family I do have are in jail. You investigated the case and put him there! It's your fault!" she said grabbing a jagged piece of glass. Sara's eyes widened- it looked smooth, and sharp as hell- it must've taken days, maybe weeks to fancy it.

"You're brother raped three women and stalked four others," Sara said stepping back. "It wasn't my fault. I was doing my job. It was his decision to as whether or not he would commit those crimes," she said backing up a little more. "I do not regret what I did one bit," she told the girl. The girl's eyes were fuming with rage.

"You bitch!" she yelled running at her. Sara jumped out of the way, but the girl still nicked her arm with the sharp object. Sara kicked the weapon out of the girl's hand and it shattered onto the ground- it was made of glass, no wonder. The girl charged at Sara and knocked her into the DNA lab table, knocking off several bottles and books. The girl grabbed a hold of Sara's neck and tried strangling her, but Sara kicked her away.

The girl quickly regained her memento and punched her in the face. Sara fell back a few steps before the girl kicked her in the stomach, sending Sara to her knees. She then pushed her through the glass wall separating the rooms and Sara winced on the ground in pain, blood trickling down her face from the small cuts made by the glass. The girl punched her until Sara's own blood was all over the girl's hands, and Sara fell on the ground, motionless. The girl grabbed her pager from her bag and stomped on it, as she did to her cell phone as well.

The 'charming' lab-tech left the motionless Sara on the ground in a pile of broken glass, unconscious and badly beaten.
