Summary: The virus breaks out in Las Vegas and the team are forced to believe in what is being said in the news. It's not long before Grissom starts his own experiment to see if he can cure the virus once and for all but not before all hell breaks loose.

Disclaimer: I don't own CSI or the 28 days later series, I never will and it makes me sad to keep saying it D: I don't have a beta so all mistakes are mine.

Thanks: As I promised any ideas that come from reviewers will be credited. I have to say JenstogForkeh and Grissom Is My Hero has given me a few great ideas and I Thank you for all your help. If none of you guys gave me any help this fic probably would never be completed :D Cheers!

"Help Him!" She exclaimed.

He wasn't responding, his legs and arms are jerking violently against the cold ground. Brass is the only one to act calm whilst his friend is violently shaking. No one is quite sure what to do or think. A few minutes earlier they had just managed to get to Grissom's townhouse, call anyone for help, check on loved ones, grab supplies and create a plan. Moments after leaving they had been bombarded by the infected. Everyone had withdrawn their guns and began shooting hap harzardly.

Everything was a blur. Sara had tried to replay the events to whether there was any sign that it was not her fault, nothing came to mind. One of the infected had taken a liking to Sara and began to run straight for her. Not thinking logically, Grissom had practically tackled the attacker to the ground.

They stumbled around trying to sufficiently kill one another. The 'zombie' looked no more than twenty five years old and it was just another perk to show people die young and inappropriate times. He was practically covered in blood, greasy hair and a large gash across his face.

Warrick shifted from his position to try and disarm the attacker but they were moving way to quick to get a clear and easy shot. It wasn't long before the infected had taken a clean chunk out of Grissom's arm. Nick instantly turned in shock and didn't hesitate to push the man from pinning Grissom down. He shot two bullets straight into the infected's head. Grissom's arm was bleeding out badly and it had soon hit the team, knowing that it wouldn't be long until he changed.

Sara was by his side in an instant, trying to apply pressure to his wound. The rest of the team were trying to figure out a way to reverse the effects. Brass held his best friend down by the shoulders, steadying him as he mumbled incoherently.

"If lemons worked to kill the zombies, wouldn't it make sense to use the juice during a transformation? You know reverse the effects?" Greg spoke trying to hold in his emotions.

"It wouldn't hurt to try, it's all we have at the moment. Where did we put the spare lemons?" Brass was still trying to control Grissom's spasm.

"Here…" Warrick handed one over to Jim where he fiddled to peel the skin from the yellow fruit.

Squeezing it carefully onto the bite, Grissom began to shout in pain. His fit had slowly calmed down and he soon became unconscious. Sara shouted his name trying to wake him up but nothing was working. She felt around his neck trying to find a pulse and relief had rushed through her when she could feel a faint rhythm of his heartbeat. Opening his eyelids to see if his pupils had dilated and they weren't bloodshot. He was okay.

"He's alive!" She shouted.

"We'll carry him the rest of the way." Nick pointed towards Warrick then back to himself. "Get him to the nearest hospital."

They grabbed Grissom by the arms and slung them over their shoulders. Occasionally he would make a grunt but never awoke. Nick and Warrick could hold him up enough to look like he had only passed out although his feet were dragging across the floor.

It was soon getting towards the evening and they had to move quickly. The parking lot was getting closer and they had decided to take a couple of the Denali's, earlier Greg had told them that Bobby always kept a couple of spare petrol container's in the back of his truck, once they were in the deserted lot Greg grabbed them and headed straight for the group.

"Who's got their keys?" Catherine asked.

"I've got mine." Sara held them up in the air and wiggled them so the keys rattled against each other.

"Anyone else?"

Brass looked around the group and answered. "Nope."

"Crap! Does Gil have any in his pockets?" Catherine pointed to Grissom still unconscious on Warrick and Nick's shoulders.

Nick fiddled around his trouser pockets while Warrick continued to try and hold him up. He found a set of keys and handed them to Catherine while he resumed his position beside Grissom.

"Right Sara, Warrick and Grissom can come with me, the rest of you go in the other." Catherine stated as Sara turned around and handed her keys to Nick whilst taking a petrol tank from Greg.

"Great so we get Ecklie?" Greg whispered to Brass.

"Just ignore him, he might go away."

"I heard that!" Ecklie pronounced his sarcasm to the young ex lab rat and the captain.

Nick helped Warrick move Grissom over to the Denali and placed him in the backseat where Sara got in on the other side. She buckled him in place and sat as close to him as possible, she ripped part of her thin jumper she was wearing to place a make shift bandage across his wound and placed his head on her shoulder as Catherine started the SUV.

The engine's roar caused a stir in the parking lot and soon another large group of the infected were on their tail.

"These guys don't quit do they?" Warrick said making sure none of them had caught up with the moving car.

"Obviously not. Is Brass behind us still?" Catherine asked while frantically looking around the front of the Denali.

"Yeah, step on it!" Sara shouted clinging anxiously onto Grissom's arm.

His head was swinging slightly from one side to the other, Sara wasn't sure if it was because of the speed Catherine was driving at of if his head was completely limp. She kept searching for his pulse making sure he was okay and every time it was there, just a little weak. Trying to keep her mind off Grissom's near death experience, with all truth he was far from being in the clear, she counted his pulse and got exactly seventy. 'His pulse is at seventy which means he's at his normal resting heart rate. That's good right?' She recalled the case that got him worked up and she had brushed his cheek for imaginary chalk. Really it was her attempt to calm him down and Sara always liked to think it had worked.

He was fully conscious of all the things going on around him, he couldn't bring himself to open his eyes and the throbbing pain in his arm was killing him. Grissom could hear Sara sobbing next to him, he wanted to just put his arm around her but his whole body seemed so much heavier than usual.

The two Denali's were racing out of the parking lot and into the dimly lit sky, slowing down wasn't going to be an option for Catherine or Brass but they had to make their way around the maze of cars sprawled across the strip. By now the group had worn off from their assault of the CSI's cars. Heading outwards to the Nevada desert, the team looked back at the destroyed city and sighed.

A/n: The last chapter will probably be short and it will be up soon. I need to end it somewhere and I apologise if it will be a bad ending. When I get the chance I'll probably revisit it and rewrite some chapters or something. Thanks for reading. Review this chapter and the last will arrive shortly.
