I don't own any of Adventure Time.

Chapter 1: Prologue

September 14th 2008

"Hey, you two! Where are you going!?"

She ignored the officer as she ran through the doors, smoke fuming around her as she entered the skyscraper's lobby.

The heat of the flame and smoke in the lobby made her eyes water. It was hot inside. There was too much smoke already that it began filling her lungs. Without a second thought, Bonnibel continued walking through the smoke, hands covering her eyes and mouth, shielding from the smoke and ash spewing from the fires. Her head swirled as she became dizzy, feeling as if she could pass out at any second from the thin oxygen alone. But then a familiar hand grasped Bonnibel's just as she was about to fall over.

"Bonnie!"

Marceline's cry jolted Bonnie back to consciousness.

"Marcie! What are you doing? I said to wait outside!"

"It's too dangerous! You can't breathe in here! But I can!"

She had a point. The black smoke and dust were building up in Bonnie's lung's, causing her to cough up a clear mucous, whereas the vampire didn't have such an issue. Nonetheless, she had to find them.

"They're in here somewhere, Marcie!"

"I know, but let me find them! I could fly up and get them!"

"You know you're not allowed to! Someone could see you!"

Bonnie held the neck of her shirt up to her mouth, wetting it with spit which filtered some of the smoke out of her throat. Time was running out. What if it was too late? What if they're dead already? She didn't even know which floor her parents were on. They never talked about work. Maybe they did, but she never listened. She hated anything business-related. If Bonnie didn't know where they were, what hope did Marcie have in finding them?

As if reading Bonnie's mind, Marcie brought her hands up to Bonnie's cheeks.

"They'll make it out! Maybe they have already!" Marcie shouted, her voice becoming desperate as she began to tug Bonnie back to the entrance. "They wouldn't want you doing this!" Before Bonnie could protest, the sound of leather shoes had made it inside the lobby from the entrance.

"They ran in here! We need to get those kids out of here!" the police captain ordered, his voice slightly muffled, "Search the smoke!"

The uniformed men spread out, gas masks protecting them from the leaden smoke and heat.

Bonnie winced at the thought of abandoning her parents. Her instincts were telling her to leave. Maybe they did get out already? If she tried to find them, she would pass out for sure. Then she would lose Marceline who would undoubtedly try and save her. God, she hated her reasoning sometimes. With a woeful sigh, she had to follow her head.

"Okay..." she whispered to Marceline, unsure if she had even heard her as the vampire already began pulling them back to the entrance.

"Sir! I think I heard them that way!" an officer yelled over his shoulder, pointing vaguely in Marceline's direction.

"Good! Find them and get them out of here! HQ says the tower's going to-"

Before the captain could finish, a rumble shook the earth beneath them. The building's steel beams echoed and screeched throughout the lobby as the ceiling began to collapse. Brick and cement hailed onto the captain, knocking him flat onto the floor, cracking the brim of his mask as he lay eerily still.

Marceline's stomach lurched as she saw what happened.

Bonnie, unaware of the captain's fate, held onto Marceline as the tremors showed no signs of stopping. She was terrified, stumbling with Marceline as they headed towards the entrance.

Steel cracked and moaned under the weight of the building, dry wall rained, bricks hailed from above. It was then that Marceline used her vision to see through the smoke and saw that debris had already blocked the way they had come in.

Bonnie, confused to as to why Marceline stopped, opened her mouth to say something. In that moment, a stray brick from the ceiling struck the back of Bonnie's skull, and her body suddenly felt limp.

"Ughh…"

Dark viscous blood dripped out of her scalp that left a trail of droplets on the floor as Marceline turned when she felt Bonnie's grip loosen.

"Bonnieeee!" Marceline screamed, seeing the wound the falling brick had made. She swiftly held onto Bonnie before she could fall over, praying that the ginger child was okay.

With the entrance blocked and Bonnie losing consciousness, Marceline was out of options. She disregarded the need for discretion as she flung Bonnie over her shoulder and flew upwards at the window directly above the entrance.

Marceline was still young. Same age as Bonnie. Her powers weren't fully developed yet as she had only started using them a few months ago. She knew her flight could only last a short time before it physically drained her. Even worse was that the sun was still up. Even with this knowledge, her path to the window didn't falter.

Twelve-year-old Bonnie felt the smoke quickly dissipate from the front of her face only to be replaced with the feeling of glass as Marceline burst through the window. The taste of smoke and ash was gone to be replaced with cool air and the metallic taste of her own blood.

The pair broke through the window and fell at least ten feet before rolling to a stop onto the street pavement.

The cries of the officers could be heard a few moments later when the lobby of Sphere Corp's building finally caved in, tipping the scale in the direction for the building's total collapse.

The emergency workers outside could do nothing but watch as smoke plumed out of the lobby and listen to the struggled cries of their co-workers inside.

Recovering quickly from the fall, Marceline heaved herself up off the cold street, her body's exhaustion amplified from sudden contact with the midday sunlight. Her legs were fatigued, yet she still managed to limp over to Bonnibel who lay on her side with eyes half-open.

"Bonnie! Can you hear me!?" Marceline shouted with the little energy she had left, tears pricking her eyes as she cradled Bonnie's head with her knees.

The ginger child fought to keep her eyes open as she watched her best friend plea for help. She looked into her best friend's eyes, tears clouding their viridescence. At this moment, Bonnie could think of nothing but how beautiful Marcie looked. Her jet-black hair was so close to Bonnie's face, frizzled from her short flight, the sound of her voice soothing the pain of a million needles coming from the back of her head.

"Somebody help me!" Marceline cried, yelling to the emergency workers who had already begun running away from the collapsing building.

With no-one to help, Marceline had no choice. This was meant for the direst of situations only. She reached for the silver necklace around her heck which held a small vial of her own blood and with a sharp tug, pulled it off her neck. Raising the vial above her head, Marceline shattered it on the nearby pavement and chanted words Bonnie could barely hear.

Her vision began to fade. Time was short before she lost consciousness but she was content knowing that Marceline was okay. Mama and Papa had to be fine too.

Because nothing else could have happened to them.

That's what happens in Papa's stories. Happy endings.

Her shoulders relaxed as her head rolled back and her eyes quivered closed. The last she heard was her best friend screaming her name.

"BONNIBELLL!"

Then all became cold.

A/N: Hey all. This is my first AT fanfic and hope that it will satisfy you. Be warned though, I plan on making this a slow-burning long story. -SnowyZoe
