Nick instantly rushed over to Sara, kneeling down in the dirt to grab her shoulder.

"Sara!" He said urgently, his heart beating a mile a minute. Almost immediately, her eyes fluttered open and she let out a small groan. Pulling herself from the dirt, she fell against Nick's chest, her body shaking with exhaustion. He clung to her, willing his breathing to slow. He slowly ran his hands from her shoulders down to her waist, and pulled her up from the ground.

"Sar, when was the last time you ate?" he questioned her gently, his hands still at her tiny waist. She had always been thin, but she seemed too skinny now.

"I don't remember," she said softly. Eating wasn't a priority to her. She had the occasional bagel and she practically lived off coffee, but she hadn't a decent meal in a long time.

Nick looked at her, concerned. "It's important that you eat, especially when you're menstruating. That's probably why you fainted."

She weakly pushed him away from her. "Don't tell me what to do," she said angrily. She brushed herself down with her hands, removing the dirt from her clothes. "You have no right to tell me how I should look after myself!"

"Geez Sara!" Nick replied, just as angry. "If you looked after yourself we wouldn't be having this conversation! What did you expect me to say? You passed out in the middle of the desert!"

His tone softened when he saw her clutch at her lower abdomen again, wincing in pain. Turning around, he grabbed the Ibuprofen and his water and took it over to the brunette. She gave him a weak smile and downed the pills, taking a long drink of water.

"Is that better?" Nick asked her gently, taking the water and pills from her. She nodded, and then suddenly fell to her knees again, crawling the few feet to the edge of the road, and throwing up what ever had been in her stomach. Her body was heaving, and Nick dropped to her side, pulling her brown locks away from her face, as her body continued betraying her.

When she had finished, Nick pulled her to him again, holding her against his chest as she shook violently. She was sweating, and he pulled her hair away from her face. Her eyes were closed, and she leant her head against Nick's shoulder, letting out whimpers of pain.

Nick could no longer hide his worry for Sara. She was so sick, and in so much pain, and there was nothing he could do. Pulling her up again, he half carried her to the Tahoe, helping her up into the passenger seat. She leant her head against the window, and Nick jumped into the car, turning the engine on. Leaning over, he placed a hand on Sara's forehead. She most definitely had a temperature, and lying outside in the cold Las Vegas desert air wouldn't have helped it.

Turning the heat on, Nick turned the car around and started to head in the direction of Vegas.

"Turn down the heat," Sara muttered. Nick shook his head.

"I'm sorry, darlin'. You have a fever. It's best if we try to sweat it out," he told her kindly.

"But it's so hot," she complained. Nick held back a smile. She was like a petulant child. He ignored her comment and continued on driving.

Sara let out another whimper of pain as another bout of pain shot through her abdomen. Having thrown up the Ibuprofen, she was experiencing dreadful amounts of pain again. She had a terrible headache and was feeling so nauseated, as well as the uncomfortable reminder that she needed a toilet.

"Nicky," she mumbled, "I need a bathroom."

He glanced at her and then back to the road, squinting ahead.

"I can't see one, Sar," he told her regretfully. "We're still in the middle of the desert. Can you hold on for 45 minutes?"

She let out a tiny moan. She didn't want to leak, as well as everything else she feeling right now. She nodded at Nick, and replaced her head against the window.

They continued on for another 25 minutes, when Sara began to feel dizzy and queasy again.

"Nick, stop the car," she croaked out. He immediately pulled the car to a stop, and she jumped out, falling again and throwing up nothing but bile. Nick jumped out as well, leaving the car on. Pulling her hair back again, he waited until her body stopped shaking violently, and pulled her to him again. He had never seen the strong Sara Sidle so weak and vulnerable before, and it was scaring him. He held her for a couple of minutes, the sound of her erratic breathing and the cars engine the only sound you could hear in the desert.

Suddenly he heard Sara give out a whimper and a sob. "Oh no…"

Nick pulled her up instantly, and saw tears streaming down her face.

"Oh God, Sara, what's wrong?" he questioned urgently. She locked eyes with Nick before her eyes swept downwards. He followed her gaze and to his horror saw blood, staining the front of Sara's slacks. He ran his fingers through his hair.

"Oh Sara," he whispered gently. He locked eyes with her again and saw pure embarrassment and misery reflected in them. He pulled her towards him again and wrapped his arms around her as she choked back more sobs. He couldn't help but feel partly responsible.

Letting go of her, he turned back towards the Tahoe. Opening the back, he pulled out a pair of department issue coveralls, a plastic bag, and the bottle of water. Turning back to her, he found her still standing where she had been before, looking completely humiliated.

"Hey, it's okay," he assured her tenderly, handing her the said items. "You get changed behind the truck, okay? I wont look, promise." He flashed her a smile and she couldn't help but let out a small one of her own.

Walking to the front of the Tahoe, he leant on the front of his bonnet, waiting for her to change, and keeping watch incase he saw a car approaching. The car was still running, the bright beams of the headlights illuminating the dry desolate tract.

His mind wandered to Sara. Something in the back of his mind told him that this was no ordinary monthly occurrence for her. Something was up. The fever, nausea and her bad stomach pain was something else. She needed to see a doctor. He needed to make sure she was alright.

"I'm done," came Sara's husky voice from behind him 5 minutes later. He walked towards her and noticed she was still shaking. She still had a fever.

"You don't usually get this sick every month," he stated softly. She shook her head, and climbed into the car. Nick followed, and soon they were on the road again.

She let out a soft sigh. "I don't know what's wrong," she admitted. Nick glanced at her.

"I think we should stop at the hospital," he said calmly. She turned to him, glaring slightly.

"I don't need a hospital, Nick," she snapped. Nick let out a groan of frustration.

"Why do you always have to be so damn stubborn?" he asked angrily, his voice rose to highlight his annoyance.

She remained silence for a few minutes, before speaking again. "Nick, I don't need to go to a hospital, I just need to go home and sleep it off."

"Come on, Sara," Nick pleaded. "You have a fever, you've been sick and you have cramps so bad that you fell unconscious. I'd sleep better knowing that you're okay." His voice quavered with emotion, and she bit her lip, surprised at his caring.

"I'm fine," she tried to assure him. Another wave of pain passed through her and she winced. Maybe she wasn't fine, but she didn't need to go to a hospital.

"I got a spare pair of clothes of in locker at the lab," she told him, "And after shift I'll go straight home and get some rest."

Nick opened his mouth to tell her something but she interrupted him.

"And I'll have something to eat as well," she said teasingly. He forced a tight grin at her, and turned his attention back to the road. The bright Vegas lights soon became visible.

Nick tried to keep his attention on the road, but he could hear Sara's whimpers of pain, even though she was trying to mask it. It was killing him. She was in pain, she needed a hospital. As they drove into Henderson, he made the decision to take her to the hospital.

She would have given just about anything to get her hands on some high end pain killers. She closed her eyes as the bright Las Vegas lights hit the window. Only a couple more minutes to the lab, she thought desperately. She'd take a shower, get changed, and then ask Grissom for the rest of the night off.

The minutes passed and eventually she opened her eyes. They were not even going in the direction of the lab. She turned to Nick quizzically.

"Nick?"

He smiled at her.

"Where are we going?"

"The lab."

They turned the corner and Desert Palm Hospital came into view. She looked back at him furiously, and folded her arms across her chest.

"I told you I'm not going to the hospital!" She muttered.

"Just have a check up?" he asked her. He pulled into the parking lot and turned the car off. Within seconds she was out of the car. He got out too.

"You have no right to tell me what to do!" She screamed out angrily. "You're not my boyfriend! You are just my co-worker! You can't tell me what to do!"

He masked the hurt of being called only a co-worker, and marched over to her.

"You're sick, Sara!" He yelled, "I don't care that I have no right to tell you what to do, I care about you! And if something happened to you tonight, I'd feel guilty that I didn't take you to the hospital! Just get checked out!"

She let out a frustrated groan, and turned on her heel and stormed out onto the street.

"Where are you going?" He called out, running after her. He grabbed her arm and pulled her back.

"Let me go!"

Nick couldn't understand why Sara was being so irrational. He was just looking out for her. She flailed against him, but she wasn't as strong as the Texan, and she soon fell against his chest.

"You're so stubborn," he told her. She looked up at him.

"I'm not going to the hospital."

"Fine," he stated. Letting go of her, he walked back to the car, and she followed. Getting in the car again, they drove in silence to the lab.

"I'm sorry for yelling at you," Sara told him as they pulled up in front of the lab.

He didn't say anything, and then turned to her.

"Did you mean what you said, Sara?" he asked quietly. "That I'm just a co-worker? Because I always thought we were friends…"

"We are friends," she said.

"Then why won't you listen to me?"

Sara made a face. "If this is about the hospital thing…"

"What if it is?" He asked her, annoyed. He furrowed his brow. "I'm just worried about you."

She opened the car door and grabbed her kit.

"Don't worry about me," she told him shortly. "No one else does."

And with that she turned away and marched back up to the lab, leaving Nick sitting in the Tahoe alone.

Please Review :D Trouble ensues! hehe that rhymes :P
