Author's Note: Wow, this is my first time writing a fanfic! Anyways, I created this story because I ship Cartman and Heidi as a couple. There's not enough fanfic revolving around them, even now since they are technically canon. I kinda hope they stay together in Season 21, but that won't happen since it's really heavily implied that they will probably break up. *Sigh* A person can dream, can't they! Enjoy the story, folks!

On a bright day in South Park, the town was on its path to recovery. The gender war that the boys and girls of South Park Elementary were going through has ended and the website called , which has caused mass hysteria in America, has been wiped off the face of the Earth. In its wake, the town has become a place of peace. It was like the town had reached a peaceful state, which it has not experienced for a very long time.

Strangers passed each other on the sidewalk and happily greeted each other as if they personally knew one another. Cars were driven slowly with drivers sighing in awe. Kids were out playing in the park, laughing in glee. It was nothing but sunshine and happiness all around. In the middle of this, two boys were walking beside each other on the sidewalk, happily talking to each other.

"Stop, I don't want to hear it! " said the portly boy in the red jacket with a blue hat. " Just shut your mouth, Butters!"

"But Eric, I'm telling you this because I don't want you go through what I been through. " said Butters with pity in his voice as he looked at his friend. "They're all conniving snakes in the grass. All girls are!"

"No, not Heidi! She's different! She makes me feel a lot happier than I ever been. " argued Cartman, not sounding too convinced by Butters.

Butters shook his head and patted his friend on the back " That's what they do to you. They build you up, making you feel like you're a gosh darn king. Then, they tear you down by pooping on your heart. That's how it's always been. " Cartman rolled his eyes and scoffed.

"Please, Butters. Just because it happened to you, doesn't mean it will happen to me too." Cartman said with confidence. Butters, on the hand, pressed on with his speech.

"Eric, it will happen to you. Trust me, you have to dump her or she will poop on your heart like my no good ex-girlfriend did." said Butters, sounding more serious as he spoke. He was trying his best to convince Cartman to see his way. The last thing he wanted to see was his friend all heartbroken and sad.

Without warning, Cartman quickly stepped forward and stood in front of him with anger. "Why don't you back off? I know what you are trying to do!" said Cartman harshly, pointing at him with a scowl.

Butters looked unsure at what he was saying. "What do you mean, Eric?"

"YOU KNOW WHAT I FUCKING MEAN!" yelled Cartman, anger rising in his voice. "You're trying to make me dump her first so that you can have a shot at her, aren't you?!". Butters closed his eyes and sighed.

"I told you before. I want nothing to do with girlfriends ever again." Ever since what he was told by a certain someone, Butters' view on girls has been completely warped, making him believe that they work in evil heartless ways. In the corner of his eye, Butters noticed something behind Cartman. He looked past Cartman and noticed someone approaching them. He looked at the approaching person and then to Cartman.

"But I guess, you just want to go through that then, huh. Don't say I didn't warn you, buddy." said Butters calmly as he closed his eyes shut. Cartman simply raised an eyebrow at this.

"Look, it's not going to happen. She's different and I won't let you take her away from me, you piece of-".

"Hey Eric, what are you doing?" A sweet voice coming from behind Cartman interrupted him. All the anger Cartman felt at the moment disappeared as he turned around to face the person behind him. It was a girl with a green jacket, wearing a red winter cap with strip over it.

"Oh, hey Heidi." smiled Eric, as he looked at his girlfriend. "I was just talking to Butters about how a great friend he is."

Heidi tilted her head and a look of confusion was spread on her face. " What do you mean, talking to Butters?"

Confused by what she had said, he stood to the side for her to see Butters. "That's Butters right there." Heidi stared ahead of her and looked back at Cartman as she shrugged her shoulders.

" What, that's Bu-" Cartman trailed off as he looked too and didn't find Butters behind him at all. He blinked and looked around. He swore Butters was right behind him. There was no way that he could have run off without a trace. Suddenly, Cartman felt a soft hand on his shoulder.

"Babe, What's the matter?" asked Heidi, sounding worried for her boyfriend. Almost instantly, Cartman wiped his face off of confusion and turned around to face her with a grin.

"Oh no, nothing babe. You got nothing to worry about. "said Cartman in a confident tone, slowly bringing his hands to interlock with hers. He would have to wonder about Butter's mysterious disappearance later. "I'm glad to hear that. Come on, I want to show you something. " said Heidi with a smile. She pulled on his hands, prompting him to walk with her.

While they were walking, Cartman was not paying much attention to where they were going, as he was too deep in thought. He was thinking about what Butters had said to him before he vanished. It was the same thing that he said from before but he sounded more serious this time. Could he really be helping him? No, he couldn't be helping. Butters is an asshole and just wants him to get rid of Heidi for himself.

Upon thinking of her, he looked at Heidi, who looked happy and anxious to show him something. He couldn't help but smile and look away. She was the only girl who actually got really close to him. Every other girl would rather watch paint dry than get to know him. She tugged at his heart, revealing a feeling to Cartman that he did not believe he could feel for somebody else other than his mom and Mr. Kitty. It was a really nice feeling. Ever since they became boyfriend and girlfriend, she held a special spot in his heart.

That's what they do to you. They will bring you down when you're at your happiest. Cartman's mind paused at this. For some reason, those thoughts formed in his mind without warning. Strange, considering that he has not had those thoughts before.

He shook his head and looked at Heidi again. She has not once done anything to wrong him. The kind and caring spirit she has shown him never wavered. All the trust she has placed in him was incredible. Nobody who knows him or of him would ever do that. There was just no way she could be a snake in the grass.

Maybe she is doing that so you'll let your guard down and then she can close in for the kill. When that thought crossed his mind, he placed his free hand on his head, trying to get rid of that thought. He had no idea where these thoughts were coming from.

Unfortunately, this didn't do anything except make him feel really uneasy. These random thoughts were starting to conflict with what he should believe in. On one side, these thoughts could possiblly be true and that Heidi is a conniving snake. On the other hand, he could dismiss them and truly believe that Heidi is genuinely nice because she really likes him. He was very troubled on this matter. In the midst of this entire struggle, he knew what had to be done in order to clear these thoughts. Cartman stopped walking and released his grip on Heidi's hand.

Upon sensing that her hand was empty, Heidi stopped and looked at him. "Something wrong, boo?" asked Heidi.

"Heidi, I want to know something," said Cartman, with a blank face. " Are you hiding something from me?"

Heidi tilted her head in confusion. "What do you mean, babe?" said Heidi, unsure why he is acting like this. He pressed on.

"Are you hiding something from me?" said Cartman, pronouncing each word as slowly as he could. She didn't say anything, only dawning a blank expression on her face. Her silence made Cartman uneasy, slightly regretting for asking her. Finally, she spoke up. " I am."

Cartman blinked and raised an eyebrow at this. "You are? Can you tell me then!?" exclaimed Cartman, making sure she didn't hear how pissed he sounded. She didn't respond. Instead, Heidi stepped closer to him, her blank expression not changing. She was getting closer until she was only a few inches away from his face. Raising her hand, she pointed a finger to his chest.

"I'm going to break your heart, Eric!" said Heidi but not in her usual voice. Cartman jumped back by the change in her voice. It didn't sound like the sweet voice he was used to. In fact, it sounded very demonic. Something was not right. He slowly backed away from her then immediately stopped when he noticed something odd. They were not standing in South Park anymore. The surroundings around him changed from the peaceful town he knew to a barren wasteland. Destroyed buildings and burnt down trees decorated the environment. A strong gust of wind blew around them, almost blowing Cartman's hat off.

"Where the hell are we?!" yelled Cartman as he frantically looked around. He was so distracted with his thoughts that he had no idea where they were or how they even got here. Suddenly, the same demonic voice spoke up, causing Cartman to look back at Heidi. Cartman froze at what he saw. Instead of seeing Heidi, he saw a large, furry monster in her place. Its body was deformed, not even recognizable as a human anymore. Its monstrous eyes were glowing red and they were trained on him. Cartman backed away slowly; his heartbeat quickened at the thought of what might come next. The monster licked its razor sharp teeth as it stared at him.

"Where's Heidi?" asked Cartman, looking from side to side. The monster laughed whole-heartily and stared at him.

"I am Heidi, you fool" Seconds later, the monster's face morphed into Heidi's face. "Don't you recognize me, babe"

Cartman started shaking when he saw that this beast was indeed Heidi. Seeing him shake in place, the monster laughed as it morphed back to its original face. It then raised its hand and brought it to its neck, mimicking a slicing sound as it moved its hand across its neck.

"Heidi, you don't have to do this." said Cartman, surprised at how scared he sounded. The monster laughed as it stared at him with those eyes.

"I have to. You lied to me, so you must pay!" yelled the monster, showing its razor sharp teeth. It took a step toward him, looking menacingly. Cartman quickly looked around him, hoping to see anyone near to help him. His search didn't last that long when he saw her let out a bloodcurdling scream and in an instant, lunged at him. Darkness fell over his mind as he screamed in terror.

"Aaaaaaaahhhhh!"

Sweat formed at the base of his forehead as he breathed heavily. Cartman was gripping onto something soft very tightly. He looked around where he was now. He was no longer with the monster in that wasteland. Instead, he saw that he was in his room, lying in bed. Wondering if he was truly awake, he pinched himself. The sense of pain told him that he was now in reality. It was just a nightmare. Suddenly, the door to his room opened up quickly, making him jump.

"Poopsikins, what happen? Is someone here?!" said Liane Cartman as she took out a gun and was pointing it around his room. She was in her pajamas, most likely about to go to sleep. Sighing in relief that it was just his mom, Cartman gained some of his composure.

"No, mom. Nobody is here. I just had a nightmare." said Cartman as he signaled for her to put the gun down. Ms. Cartman looked at her gun and then placed it away quickly, feeling embarrassed by what she did. She sat on the side of bed, next to Cartman.

"I'm sorry hun. What was the nightmare about?" asked Ms. Cartman as she wrapped a hand around Cartman.

"It was about my girlfriend. She turned into monster after telling me that she was going to break my heart. I begged her not to but then she told me that she has to because I lied to her about something but I know I didn't. I was so scared for my life and wanted to get away from her but then she attacked me." said Cartman quickly as a small tear was rolling off his eyes. Ms. Cartman took a couple of seconds to process what she just heard.

"There, there, Eric. It was just a nightmare. A nightmare cannot hurt you." She comforted him as she patted him on his back.

"But it looked so real" wailed Cartman.

" I know it might have but its not real, sweetie." said Ms. Cartman, trying her best to cheer him up. Moments later, Cartman finally calmed down with the help of his mother. He thanked his mother, who in return smiled back at him. She got up and tucked him into bed properly.

"Sweet dreams, Eric." said Ms. Cartman as she turned to leave his room.

As she was starting to head out of his room, Cartman instantly remembered something.

"Mom, do girls turn into a monster if you lie to them?" asked Cartman with curiosity. Ms. Cartman paused for a moment then shook her head.

"No, sweetie, they don't. Now, try to get some rest." said Ms. Cartman as she left the room.

When his mom left, Cartman laid in bed as he stared at the ceiling. He was glad that his mom said that but part of him didn't believe it. For all he knew, this nightmare could turn out to be true. Heidi could turn into monster if she found out that he lied to her. As soon as that thought crept into his mind, he had trouble falling back to sleep again.
