Fionna just ran into another human! Le gasp!

By the way, tomboy, I will use your song just in a few chapters. It was really good and I liked it but please hold on a while.

I have nothing more to say. :)

Disclaimer: Nope. Don't own it.

He stared at her wide-eyed, her sword glinting dangerously in the weak lamp light, pointing directly at his heart. Fionna didn't dare move an inch. She was practically frozen on the spot as the sight of the boy sunk in, realization spreading through her body like a cold drink after you drink it on a hot day. The silence echoed loudly, their equal surprise pounding in the hearts as they took in the sight of one another. Fionna had to be dreaming. There was no other explanation. Humans were gone, right?

But wasn't this the kind of thing she was searching for? More humans to talk to about the war? Fionna's hand gripped the hilt of the sword, unsure if he was still an illusion or just a monster, demon, or shapeshifter playing a trick on her like they would have back in Aaa. The boy blinked a few times before calmly adjusting his glasses. His eyes glanced down at the tip of her sword and them back up at her. Then he spoke with the most curious accent Fionna had ever heard.

"So... are you going to stab me?" he said, his eyebrows raising slightly.

"I'm still deciding," Fionna replied truthfully.

The boy grinned and shook his head. "Don't worry. I'm no threat to you. I can see by your stature that I couldn't stand a chance." Fionna hesitantly lowered her sword, eyeing him as he continued to talk. "Well, welcome to my library... of sorts. I do apologize for the mess but it hasn't been cleaned for over one thousand years, it seems."

"Why do you talk like that?" she asked, cocking her head a little to the side.

"Well, according to halo-tapes I've seen about my culture, my ancestry hails from a place called England. Sometimes called the U.K. for United Kingdom," he explained, scratching his brown hair, thinking about an explanation. "By your accent it sounds like you're from America or perhaps small bits of Canada."

"Wha-?" Fionna said. "I've never heard of those places."

He looked surprised. "Really? They were quite popular tourist attractions before the Great Mushroom War."

"You know about the war?" Fionna said, her face brightening and a glimmer of hope igniting in her heart.

"Why, yes. I've been researching it ever since I turned thirteen," he explained, smiling at her expression. "And it seems you're interested in what happened to the humans like I am."

"I thought I was the last one."

"As did I. I have heard rumors that they reside somewhere beyond this city." He pointed in the direction towards Aaa. "Somewhere over there."

"You're outta luck, dude," Fionna said, shaking her head. "There's nothing there but Candy people, vampires, ghosts, Lump Space people, you name it. I'm the only human that has ever lived in Aaa."

"Aaa? That's what it's called."

She nodded and he chuckled a little.

"That's a fascinating name, isn't it?" he said. "Speaking of names, I have yet to introduce myself. I do apologize. My name is Charlie." He stuck out his hand towards Fionna and she shook it.

"My name is Fionna the Human- erm, uh, just Fionna now," she said, a small blush crossing her face, giddy at the thought she was actually talking to another human being.

They dropped the handshake and Charlie picked up a few books he had dropped from his encounter with her. He then led Fionna back to the desk that was now obviously his. Placing the books back on his desk, he began to explain a few things to her.

"I found this place over a year ago," he said.

"But your note says four days or something... sorry I read it," she said quietly.

"That was four days after I found it last year," he said. "And I forgive you. Curiosity is not a sin, Fionna. It's no big deal anyway... As I was saying, I found it over a year ago and took residence here to study up on human history and hopefully find some information on the war. It seems to be a pre-war library so no such information exists." He sighed and dusted off a book. "And I have found so much out of the pages of a book and they became my ally. Sadly, they have yet to provide any information on the war." He turned to her. "But what's your story? If you come from Aaa, why did you leave?"

"I'm trying to find out what happened to my people. Our people," she said, a smile crawling across her lips. The joy in saying that filled her to the brim. "I'm traveling to the big crater that was caused by the Mushroom Bomb. A friend of mine said that was the end of the world as he knew it so... there has got to be something useful there, y'know?"

Charlie nodded and began to write something down on a notepad he had taken out of his pocket. "I see. That's a very good deduction, Fionna. I never thought about searching the crater. These abandoned cities only supply bad thoughts and theories... the next thing to check would logically be the crater."

Fionna had never heard someone speak so intelligently and respectfully towards her. Sure Gumball cared for Fionna but she knew that he felt a little superior to her due to his brains. While Fionna supplied the brawn and did dangerous tasks for him, Gumball still looked down on her slightly. Charlie barely knew Fionna for ten minutes and was threatened by her in half a second but he spoke to her as if he had known her forever. This pleased Fionna greatly and felt like an equal for once.

"You think so?" she said softly.

"Of course!" he said, his head perking up from his writing. "Fionna, I do believe you're on to something."

Her face burned with flattery and excitement. This boy was... so nice to her. Fionna had a feeling in her gut that he was going to be a great friend for the short time they had with one another before she had to troop back off to her destination. Maybe she'll see Charlie there...

"Do you wish to stay a while?" he asked politely. "I'm afraid I don't have beds but there are some very comfy couches in the reading room we can use. Perhaps we can discuss our separate theories on the supposed human extinction."

"Sure! That sounds Math," Fionna said with an ecstatic grin. Then it faded a little. "And, Charlie, can you dumb it down a little for me? I'm afraid I'm not that smart."

Charlie laughed. "Fionna, you're just as intelligent as me. No worries. I think you can get the gist of what I'm saying."

Fionna's smile lifted and she followed him into the reading room where several more piles of books were stacked against the walls, crumples pieces of paper littered the floor, and one of two couches was covered in a worn out blanket and a pillow that was slowly losing its stuffing. Other notes with Charlie's handwriting were scattered about, some on another desk, some on the floor. A coffee table with discarded, yellowing magazines sat between the two couches, more of his notes piled on top. Fionna took in the room, the weak light being cast down by a single lightbulb dangling on a string in the ceiling. Charlie shrugged humbly and said,

"It's not much..."

"It's nice," she said truthfully, walking over to her couch. "You really don't mind me staying here?"

"Not at all!" he said, striding over to his couch and sitting down. He nodded for her to sit and she did so, putting her sword sheath against the armrest and pack where a pillow would go. "If you don't mind me asking," he said, "would you tell me how old you are?"

"I'm seventeen," Fionna said without blinking. "What about you?"

Realizing she didn't care one way or the other what he asked, he replied feeling less awkward. "I'm seventeen and three quarters."

"Well, Charlie, I'm very pleased to meet you," Fionna said, imitating his accent, making him laugh.

"Likewise, Fionna," he replied, trying his best to imitate her accent as well.

They both started to laugh with one another. Fionna decided to sleep for the time being until morning since she no longer had to worry about getting burned by the sun. Charlie slept too, tenderly placing his glasses on the coffee table. They awoke around the same time and spent the day talking about their own theories and reading up on human history. Fionna couldn't remember having this much fun while learning. Around noon, they took to snacking on a few things Charlie was able to salvage from the bakery's freezer that wasn't completely gross. Fionna took out the sack of little people and took out her little self and three friends. Charlie watched, fascinated, as little Fionna jumped on little Marshall Lee's back and pointed forward. Begrudgingly, Marshall moved forward and little Fionna laughed with glee. The bigger Fionna pointed to each of her friends and told Charlie all about them.

It was a while until he spoke up, "How incredible. Tiny replicants of you and your friends. How did you come across them?"

"I just found the bag in my pocket one day," she said, taking out Ice Queen and putting her on the table. She watched her mini self and little Ice Queen battle it out while the others cheered on the sidelines. Charlie laughed at their interactions and tried his hand at playing with them. He put Gumball next to Marshall and watched them start a normal conversation but soon grow enraged with one another. He didn't understand why Fionna was giggling so hard as the mini boys started fighting with one another but Charlie didn't question her about it. Fionna took them away from the table and placed them back in the bag. She and Charlie finished their meals and moved on with looking up an old age war called the Cold War.

"It says here that it wasn't a gun war," Charlie said, peering up at her from a book. "More of a war of intimidation. Several mini wars were spread throughout the span of the Cold War but it wasn't an all out war like the Great Mushroom War."

Fionna laughed. "You said 'war' so many times it sounds weird now. Warrrr... wwarrrr-a."

"War is simply a weird thing in general," he mumbled to himself. "I can't believe there were so many hateful people. Why couldn't they be more like us? Simple, kind, and intelligent."

"There were few," Fionna pointed out. "The last one was probably Simone Petrikov."

"Who?"

"No-one... she's long gone."

Charlie looked at her questioningly but continued on with his research. Fionna ended up staying with him for two more nights until she felt that she had overstayed her welcome and that it was time for her to move on. So on her final night, she told Charlie that she had to return to her journey and get to the crater. Instead of looking crestfallen, he brightened and put down the piece of cake he was munching on.

"That's what I wanted to ask you about, Fionna," he said. "I was wondering if I could possibly join you on your little adventure."

"You wanna go with me?" Fionna said, surprised.

"Of course! I feel like it is not only your duty or mine on our own. But our duty," he explained. "Fionna, you and I could go to great places together. Two heads are certainly better than one, correct?"

"I suppose."

"If you will allow me to, I would be honored to go along with you."

"You know what, Charlie? You're absolutely right. You and I have a job to do for our peeps. I'd love it if you joined me."

So after dinner, Fionna helped him pack up his own backpack with some books, containers of food, his blanket and pillow, several of his notes, a map, some technology he claimed to be useful, and among other things. He said he had a few other places he had inhabited over the years and said they could stop by and search for his old stuff he might have left behind if they came across it. Fionna agreed and the two of them left the library together, the moon hanging in the sky. The female human ran a little ways ahead, her sword banging gently on her side as she twirled a little, pumping her fist in the air, no longer feeling alone or upset.

"It's Adventure Time!" she cried out, grabbing Charlie's hand. The two of them ran together down a road that was unknown to the both of them.

Back in Aaa, things were quiet. All around the Grass Lands, to the Candy Kingdom, to the Ice Kingdom, the Nightosphere, Lumpy Space, the numerous graveyards, and so many other places, everyone was in a hushed silence as they dwelled on the whereabouts of the greatest hero in the land. King Gumball, Marshall Lee, Lord Monochromicorn, and Cake were all in the Tree Fort after a quiet dinner together. Cake had invited them over since it was very lonely by herself without Fionna. Mocro suggested that she stay with him for the time being, telling her that their kittens often visited but Cake denied the offer. As much as she loved seeing her little kitties, she felt that leaving the treehouse was like Fionna leaving Aaa: the place would be vulnerable. Even though she hated Gumball for saying it, she had to admit that Aaa was a dangerous place without Fionna to protect it. But Cake found it odd that Ice Queen wasn't leaving her castle and that monsters refused to come out of their hiding places. It was as if they didn't want to take Aaa or any princes or whatever their evil business was without a fight. Fionna was what made it a challenge and Cake was a little relieved she only had to fight a monster on only a few occasions.

Marshall Lee had taken care of Ice Queen. He was starting to see her more frequently and spent time with her, telling her to back off from the princes. Something about him stirred something in Ice Queen so she sourly listened to the Vampire King by staying home and playing with her penguins. Marshall would bring other things to keep the two of them entertained such as a keyboard or his guitar or something like that. He would spend countless hours begging her to take off her stupid tiara willingly and think. But Ice Queen would laugh and call him crazy, making his attempts fruitless and bare. Ever since he had told his story to his friends, a fire arose in him. It was a tiny, desperate flame that was begging to be kindled to new heights that was trying to get some sort of closure with the Ice Queen. His fire was trying to put out the icy prison she was held in and all he wanted was for her to remember something. So his time was spent with Ice Queen instead of teasing and flirting with Fionna, scaring the daylights out of Cake, annoying the heck out of Gumball, or haunting the Grass Lands in the late hours of the night.

Gumball was now more preoccupied with his kingdom now that he wasn't being captured every other week or so. His experiments were still the same but he was happily focusing on ruling his people. It wasn't like he didn't miss his time with his friends but he felt... freer than he had before. He was able to deal with problems with the Lady of Orangegrab, keep Goliod in his place with the help of Storma, and only caused one zombie attack that lasted for an hour. Things in the Candy Kingdom were never more peaceful without it being threatened everyday or so.

Cake was still as lonely as ever. Taking his offer into slight consideration, Cake would only visit Mocro and her kittens when they would come to call. She would be the hero if there were any disturbances around the land of Aaa but they were usually small things. She would spend hours in the treehouse playing BMO or practicing her dulcimer. Cake had taken to sleeping on Fionna's bed, curling up beneath the many animal furs her sister had collected over the course of her life. She would somberly sing "Bacon Pancakes" to herself and make a small batch. Without Fionna's heavy appetite, there was no need to cook a huge meal for just one cat. Cake deeply missed Fionna and wished for her safe return every night before she drifted off to sleep.

It was as if Fionna's leaving was a good thing. But it wasn't. Even though Marshall was having and okay time and Gumball was managing well on his own and Cake was living her life a little differently, there was huge hole in the world. The hole that Fionna left empty when she left. She was truly the light of Aaa and made it exciting to live there with all of the mystical creatures and grand adventures. Cake would sometimes find Marshall singing somberly to himself, a few lyrics entering her ears that would sound like he was talking about the bunny-hatted girl. She would even catch he and Gumball having civilized conversation. Fionna's leaving left time to patch things up, Cake concluded. Since there was so much to worry about with Fionna here and Ice Queen running wild, it was hard to stop and actually appreciate life in Aaa as it was.

The conversations, although sounding civil, were still critical when Gumball and Marshall Lee met up. However, something was eating the two boys from the inside out and they both knew there was much more to be said to one another than just lowly snaps. They had a past together that had to be fixed and perhaps Fionna's absence was the perfect time to do it.

So they went on with their lives. Slowly, but surely, days passed and soon Fionna had spent an entire month away from home. Of course, the others in Aaa had no idea that she was now traveling with Charlie in a larger city, spending a few weeks there searching for things that could help them on their journey. So far, nothing was of use to them but they kept on moving on.

They were running to their future but diving deeper into the past.

There you have it! Chapter five. And someone asked me to tell when I would be updating and here's my answer:

It's all really irregular. It depends on my mood and whether or not I want to write Adventure Time. I'm currently borderline with a Hetalia and AT phase so I can work with both. Don't expect weekly of daily updates. Just please bare with me and my random updates.

Thank you all so much for reading and please review!

See you next ADVENTURE TIME!
