Okay, so this is kind of experiment. The idea came to me last night while I was trying to sleep and I immediately jotted it down. It's kind of a crossover with World War Z. I say kind of because the only thing that I use from that movie is the fact that the walkers only go after people who are healthy. They are still the same walkers from TWD otherwise. They don't run super fast and they don't just take a bite out of their victims. I've only seen WWZ once and I'm pretty sure that you had to be terminally ill for them to not notice you, well in this story one can just come down with the flu and be invisible to them. This story is also AU from season 3. Everything in Season 3 happens, except the Governor is dead in this story and Sasha, Tyreese and Karen are now running Woodbury. I hope that all makes sense and if it doesn't, feel free to message me or something. It's also not angsty at all, so that's a good thing, too. Well for me, it is. There is only so much sadness you can read. I hope some of you enjoy this, I am very nervous to post it. I don't know why. So, let me know what you think!

Enjoy!

Part One

Daryl Dixon had always been a healthy man. Even as a child, he rarely got sick and that had been a miracle considering the shithole he and his family had lived in. He supposed he had that period of his life to thank for making his immune system so resilient.

Being healthy and strong over ninety-nine percent of the time had been one of the only good things to come out of being a Dixon.

Much help that was now.

The apocalypse had started, the dead rose and started eating people. Not just any type of person. They preferred to dine on only the healthy ones. Who would have thought that being healthy was the only thing that could you killed?

It had happened so fast, the moment when the deadly virus had spread. One minute everything seemed fine and the next; people were turning and eating other people. No one knew how it had happened and no one knew how to stop it.

They didn't find out until the CDC that the walkers only went after those that were healthy. If you were sick with anything from the flu or to cancer, then they'd leave you alone. Like you were invisible.

It was useful information, they all agreed, but Jenner didn't let them dwell much on that before he dropped the bomb and said the place was going to blow up. If it hadn't been a talk with Rick and a grenade from Carol, then they would have all been dead.

Now, a year later, there was only five of the original group left, plus the Greene family, Michonne and baby Judith.

The prison was safe, for now. The Governor had been taken care of, but not until after he killed Andrea and Merle. Tyreese and Sasha helped run Woodbury with the help of Karen and a few others. They were on friendly terms with the prison group and things seemed to be going good. Well, as good as things could get when there was dozens of hungry walkers piling against their fences.

Daryl looked down from his spot on the watchtower. They no longer had to keep watch, with the Governor gone, but he still liked to go up there and get a bird's eye view of the prison. Now, he watched as Glenn, Maggie, Beth and Carol stabbed the heads of the walkers that had began to push on the fence and causing it to sag.

All four of them were spread out. Carol was at one end and Glenn on the other, with the other two spread out between them. Together all four of them banged on the chain link fence to lure the walkers to them. Daryl quickly noticed that none of the walkers went towards Carol. They looked in her direction when they heard the noise, but didn't move towards it. It was as if she was invisible to them...

In a matter of seconds, Daryl was out of the tower and walking quickly in her direction.

Carol banged at the fence with her crowbar, but none of the undead came her way. She paused a moment and watched as Maggie, Beth and Glenn thrust their weapons through the walker's foreheads. None of them had noticed that she hadn't killed anything yet.

Wiping the sweat from her brow, she went back to shaking the fence and shouting; hoping some would come her way.

A rough hand wrapped around her bicep and caused her to pause in her yelling. She knew that calloused hand anywhere, even if he rarely touched her with it. Turning, she came face to face with Daryl. Things with him were going a little...slow. Too slow. She liked him, probably even loved him, and she flirted mercilessly with him, but so far she only got a half smile and a half hearted 'Stop' whenever she did.

She was on the verge of giving up any hope that they could be something other than friends. It had been several months since they had first started to get close and nothing had come of it, yet. She was beginning to think he wasn't interested and when he said stop, he meant it.

"You sick?" He asked and his gaze raked over her body. His hand remained wrapped around her arm.

"No," she answered.

"Bullshit." He let her go, grabbed the crowbar from her hands and walked up to the fence. Within in seconds, two walkers had found their way to him. He turned and motioned for her to stand beside him. Without saying anything, she joined his side and watched as he began to walk further down the fence and away from where she stood.

The two walkers' eyes roamed over, but didn't lunge at the fence like she thought they would. From his new spot a few feet down, Daryl kicked the fence loudly and managed to gain the attention of the two walkers. Without a second glance at the woman in front of them, they began to limp and snarl in his direction.

He gave her a pointed look before turning to the walkers and stabbing them through the head with his knife.

She didn't feel sick. She did have a headache, but that was because she hadn't gotten much sleep the night before due to Judith's crying, and she felt hot, but that was to be expected when one worked outside during a summer day in Georgia.

Once again, his hand wrapped around her arm. "Come on, let's get you inside and checked out by Hershel."

"I feel fine, Daryl," she said as he led her away to their cellblock.

"Well, somethin' is wrong with you if them walkers were actin' like you don't exist." His hand moved to hover over the small of her back as they walked into the cellblock.

"Aw, Daryl, are you worried about little old me?" She smiled at him over her shoulder.

The corner of his mouth quirked up and they stopped outside of Hershel's cell, where the man was sitting and reading an old bible. "Shut-up."

Twenty minutes later, Carol found Daryl lying in his cell fiddling with an arrow. When he saw her in his doorway, he sat up. "Well?" He asked. "What the Doc say?"

"I just have a fever." She shrugged. "It's barely a hundred, but I guess it's still sick enough to become invisible to the walkers." She took a seat at the end of his bed when he moved his legs to give her room. "So, I told Rick that I would go on a run for him tomorrow if I'm still sick."

"What?" The arrow in his hand clanked to the ground and he sat up straighter to look at her better. "By yourself?"

Carol rolled her eyes. "No one else is sick, Daryl. It would kind of defeat the purpose if someone went with me."

"Like hell you're goin' by yourself." He got up from the bunk and stood in front of her.

Carol followed suit, crossed her arms angrily over her chest and glared up at him. "Are you saying that I can't take care of myself, Daryl Dixon?"

He looked lost for a moment. "What? No. It's jus' that anythin' could go wrong out there and no one should go out alone." He knew she was capable of taking care of herself. Hell, he was the one to make sure of it.

"Well, unless someone else gets sick between now and tomorrow morning, it looks like someone will be going out by themselves." She looked at him defiantly and willed him to argue with her. She had also become very stubborn over the months and he would deny it vehemently if anyone said that she got it from him.

Daryl stood silent for a moment and brought his thumb to his mouth to gnaw at the skin there. Suddenly an idea came to his mind. He looked down at Carol, who was looking up at him. Without a word, he grabbed her shoulders, hauled her body closer and smashed his lips to hers.

She gasped into the kiss and he used that moment to slip his tongue in her mouth. Surprisingly, she began to kiss him back almost immediately. Daryl thought she'd have pushed him away by now or slap him. Or both.

His tongue swept the inside of her mouth and danced with hers before he broke off the kiss. His hands never left her shoulders and he smirked down at her. "Now, all we gotta do is wait."

Carol returned his smirk with one of her own and wrapped her arms around his neck. "I don't think that just one kiss is going to work, Daryl."

What are your thoughts? Hopefully some of you will stick around to read the second part, which should be up soon! :)
