One-Found

Finn laughed at Jake while he did some funny dance moves with BMO. Today so far had been a good day in his opinion, he had an absolutely mathematical dream about being a hero with both Jake and Flame Princess at his side and had an awesome heroic breakfast of sausages and eggs with his brother. Now he was just hanging until it was time for Jake and him to pick up FP for some trio adventuring.

He looked at the clock before getting up and made his way to the door,

"Hey Jake, it's time to pick up FP." he called.

The magical dog stopped at his words and turned to the still grooving little robot after nodding his understanding.

"Cool, alright see ya BMO; don't get into anything too bananas while we're away!"

Jake made his way to the door and followed Finn out while BMO called out an affirmative to stay out of trouble and continued to dance to his own soundtrack.

Both laughed at his antics as they closed and locked the door and headed off. They walked with their usual cheerful silliness, making jokes and simply enjoying the sunshine as they walked to Finn's girlfriend's house. Their mood was abruptly killed when they got there, for outside her house was Flame Princess, doing her best to fight off some odd rock golems. There were quite a number of them and although the young fire elemental was holding her own very well it was obvious she was in need of assistance for her opponents didn't seem very fazed by fire. She just kept shooting wave after wave of flames at them yet all it did was knock them over, their outer surfaces barely glazing over from the immense heat of her attacks.

The two heroes immediately kicked into action.

With a heated cry of "Hey! Don't be messing with my lady!" Finn grabbed his sword and charged into the fray, Jake right behind him and growing in size so he could start trashing the rock golems.

Flame Princess gave an excited shout at seeing them and, with renewed vigor, continued her fight with her opponents. And at first it seemed victory would be theirs with the way the golems began breaking under the combined efforts of the heroes. But almost immediately after being broken apart the pieces of rock creatures would reassemble into new beings, which in turn fought with never wavering strength. It seemed as if they might be over run.

"Finn, man, things are getting crazy here, we need to retreat!" yelled Jake just as a rock golem punched him in the leg.

"Ow!" He cried as he lifted his foot and brought it back down upon the same golem.

Finn grunted, acknowledging his brother's point and noticing how Flame Princess, despite her grand love of the battle and destruction of all things evil, was obviously getting tired of this fight and was visibly exhausted.

But then a shout rang out in the air, every one (including the golems) turned in surprise just in time to see a cloaked figure join the fray and start demolishing rocky homunculi. But instead of just breaking them (which they impressively accomplished with a single swing of a thick sword) they also smashed a small blue stone that Finn hadn't noticed fall out of the golems before. He noticed that once said stone was destroyed, the rocks formerly attached to it no longer moved.

He turned to his friends who had gone back to fighting

"Hey! Do was this guy is doing! Smash the blue stones!"

They heeded his words and soon all of the golems were gone and only odd, glazed rocks remained. They then turned to the figure who was standing tall and watching them. They breathed heavily and held their sword limply in their gauntleted hand at their side. Now that he was able, Jake took a good look at their sudden "ally".

They wore a thick looking dark green jacket with the hood up, this obscured their face with shadow but he spied some bits of blonde hair straying out into the sun. The stranger was rather tall, at least taller than Finn by half a foot by the looks of it, and lean and female if he was not mistaken. That jacket was thick and looked a little big but it did not hide their gender very well once one actually looked. The woman- he now saw- also wore thick black pants with black boots and carried a dark blue backpack on her back.

Jake squinted his eyes as he –and FP he idly noticed- shrank down to normal size and went to stand by Finn, who was closest to the female.

"Uh thanks for the help. Who are you by the way?"

"Yeah, what he said." Stated FP, on guard for anything, you could never be too careful in the land of Ooo.

But the figure just chuckled as she sheathed her weapon, seemingly not at all insulted or intimidated.

"Oh yes, I guess it is about that time to introduce myself." She said.

With that she lifted her hands to her hood and pulled it down, revealing blonde bangs and bright blue wavy hair swept back into a pony tail and a distinctly human looking face. She smiled at their collective gasps,

"Yes, yes. Hello, I am Bethilda Mertens the Human. But you can just call me Beth."

"Another human! Finn, I can't believe this brother! You're not alone!" Jake was ecstatic, his buddy finally found another of his species, now he wouldn't feel so alone like he knew he did sometimes. No matter how much the young teenager tried to hide it.

Flame princess simply stared at the now dancing dog and shell shocked water elementals- humans-she corrected herself; her boyfriend was a human.

"…..Your name is Finn?"

Although the young woman's voice was small and broken, just barely above a whisper, the desperate hope within her tone brought the others out of their thoughts and stopped Jake's dancing. Hesitantly Finn stepped forward and answered in the affirmative.

"Yes, I am Finn the Human, formally the last Human in Ooo and a Great Adventurer."

His tone was serious and cautious; Jake was concerned but curious to see what happened next. And of course Finn would never call himself a hero (even though he was) just an adventurer.

Tears began to appear in the corners of the woman's eyes, "I have been searching for you for weeks! Finn….I-I know you won't remember me but I'm your big sister!"

They all gasped once again, none so more than Finn.

"What?! B-but that's not- how- when?!"

The poor guy was flabbergasted, how could this be? He already had brothers, how could he suddenly have a sister? A Human sister at that?! It was almost too good to be true. The young woman- Beth- took a step forward but Finn's automatic step back caused her to pause. But there was no hurt on her face, just sad understanding.

The others around her young brother-she could just tell it was her little bro from the face, he looked just like her dad as a boy- were simply silent until the two humans started to move. Suddenly the little orange dog-Jake was his name right? - was pushing the boy and flame using girl behind him and puffing up his size to be eye level with Beth.

"Hold on there, what you're saying is bananaz! My parents found Finn alone when he was just a baby, if you're his supposed big sister where were you!?" His words were defensive and challenging.

Last human or not, Jake wasn't about to let this lady get away with anything.

Beth protested desperately, "I can prove it!" and briefly dug in her jacket pocket before producing a much abused laminated photo. Jake took it and backed himself, the still shocked Finn, and the silently observing princess of flames away a few steps. He held the photo up so all three of them could see. The picture was of a small family, a group of four.

There was a middle aged man in the photo wearing adventurers' clothes in tones of blue and red and had long, wavy brown hair tied back in a ponytail. On his face was a large daring smile surrounded by an epic short beard, cleanly combed and with a few braids. He looked what Finn would look like in another twenty years and a dye job. In his arms he held a brightly grinning little girl; she wore a dark green, sturdy looking dress with what looked like black leggings and boots. Her hair was an odd two-tone of blond bangs and golden brown hair, her face like a miniature version of the owner of the photo. Next to the happy pair was a smiling woman with Beth's face and shining blonde hair cropped stylishly short. She also wore adventurers' clothes in orange and black tones, in her arms was an adorable young baby boy wrapped in a baby-blue cloth and a little white hat over his head. It was a tad too big, allowing for just a tuft of gold hair to sneak out. His smile was one Jake would recognize anywhere.

"Whooooaaaa…" The dog was speechless, it was true. All eyes were wide.

The almost crying woman before them really was Finn's long lost sister. He heard a sniffle next to him and turned his head see Finn barely containing tears of his own. "Finn-"He stated but was interrupted by the young man by his side.

"I-I'm okay brother, g-give me that"

Taking the photo from Jake's paw Finn walked over to Beth, he stopped just a step away from her and stared. A million questions swirled in his head and a weight he had never realized he held was lifting off his shoulders. He handed the photo back to Beth and she immediately folded it and put it back in her pocket. A small smile came to his face and he stepped forward, embracing the now audibly weeping woman before him.

"Finn!" she cried, burying her face into the fabric of his hat.

"He sis." He said softly, silent tears falling from his eyes as he felt her arms wrap around him tightly.

A sense of unfamiliar familiarity settled within him. He rested his head on her shoulder and took a deep breath, taking in the smell of another of his race. After a few minutes Beth was reduced to just sniffles and she pushed them apart enough so they could face each other.

"I know you have a lot of questions, and I'll do my best to answer them all."

He grinned, "All in good time. For now let me introduce you."

Turning in her embrace-it seemed he was as reluctant as her to reduce contact- he pointed to the flabbergasted dog.

"This is Jake, my adopted brother and best bud in all of Ooo." He turned to the girl she now realized was made completely of flame, not just using flames.

"And this is my girlfriend, Princess of the Fire Kingdom, Flame Princess or FP for short."

She was cute.

'Way to go bro.' she thought.

Both of Finn's companions waved as they were introduced and smiled a little, both humans looked so happy. Still grinning Finn broke out of Beth's embrace to take her hand and start pulling her forward.

"Come on! You need to come see our home; it's an awesome tree house! We'll give you a big tour, right Jake?"

The dog had seemed to finally break out of his astonishment and was now all curling, shifting energy, "Right! And she can meet BMO!"

"Right! And then you can tell us everything! Come on."

He was grinning so much right now. Finally! Finally he would know, and now he had one more ally to add to the team. He tugged a bit harder of Beth's arm in his excitement and continued to go on about everything she'd see and what they would do. She sighed happily, not at all bothered by her brother and his understandable enthusiasm.

Her brother, oh thank the goodness of the world for allowing her to achieve her goal after her long journey. She looked off to the right to see the flame girl standing a tad awkwardly to the side, making no move to follow them, a frown on her face. Finn noticed just as she did.

"Come on FP! You're a part of this too!"

Beth smiled as the small frown on the girl's face turned into a small grin and she quickly caught up with the group, taking a place next to Beth.

She smiled and said "Nice to meet you." A little shyly.

Still smiling, Beth said "Nice to meet you too" and they both laughed as Finn tugged on her arm again to gain their attention. The group made their way down the road, toward the next big adventure.
