[Prologue:]

In the Land of Ooo a young boy sighs as he looks outside of the tree fort home in which he resides in during a rainy storm. As he watches the outside, he wears a cyan shirt and navy blue shorts; as well as a white hat with small bear ears.

Noticing the young boy depressed, a light orange talking dog asks him, "What's wrong bro?"

Rather than respond, the boy just sighed and continues staring out the window.

The dog continues,"Finn, buddy. I'm sorry ok? But you know why we can't see her, right?"

"Mmm..." was all Finn could say in response.

"Well, I'm off to bed then, don't go do something crazy." the dog finishes as he climbed the ladder to their bedroom.

"ok Jake..." Finn mumbled. As he best friend and brother went off to bed, he remembered what happened that fateful day a couple nights ago...

[Flash-Back]

"..It's a girl!" Finn exclaimed as he saw the girl dowsed from PB's liquid-rockets begin to fall off the tree fort's roof. Without a second thought, Finn quickly reacts to save the girl from falling, Using the wad of hair to hold him. Once he caught her and dragged her back into the home, he took a quick glance on her beauty.

Now awake, the girl quickly gets off and dries herself, then yells at him.

"What's wrong with me, huh? You don't like me!" She yells in anger.

"I like you..." was all Finn could say in response.

Blushing, she paused for a second. She snaps out of it and continued, "What's wrong with you!" After drying off, she shook her hair back to it's original state and gave a good hard slap to Finn, leaving a stinging hand-shaped burn mark on his face. "Don't EVER mess with me again!" she warned him as she left, leaving the home in ruin from her presence.

Finn was shocked at what had occurred that he didn't say anything for a while. Then, as though to break the silence Finn turned to his bro Jake and asked, "Who was that?"

"The Princess of the Fire Kingdom..." Jake responded nervously.

Finn looked back to the window then back to Jake, quiet. "... Dude...I think I have a crush..."

"Whaaaaaaaat!" Jake shouted just as histerical as he reacted when he found out that Flame Princess was evil. "Dude, you can't have a crush on her! She's evil! She just tried to burn our house down!

"Y-Yeah, but..." Finn looked down,"I really like her..."

"NO! NO BUTTS! I know it's my fault this had happened.."

"Wait... Jake? What did you do?" Finn asked with a stern look.

"Oh uh... well..." Jake felt guilty that this had happened that he didn't want to say.

"Jake! Tell me!"

"Ok! ok! Fine..." Jake then took a deep breath and then shouted everything that lead to what had just happened in a quick long and hard to listen sentence. After Jake quickly finished telling Finn, it became silent again.

Using this time of silence, Finn tries to fully comprehend everything what Jake had told just told him.

"Finn..?" Jake suddenly asked.

After a minute or so, Finn then says,"I still like her..."

"No way, dude, you can't! SHE'S EVIL! We both just saw what she can do!"

"So? You said Marceline was evil too, and she's actually a radical dame"

"Well she's different"

"No she isnt"

They then continued arguing with Jake saying about how Flame Princess was not right for him and Finn going against it. It ended with Jake forbiding Finn to go after Flame Princess, even if it meant he had to tie Finn up. Rather than go through with that, Finn reluctantly agreed...

[Back to present]

After everyone in the tree fort was asleep, Finn quickly got his prepared stuff and went out to meet with the Flame Princess. Knowing that Jake had caused such an uproar, he felt it was his duty to resolve the misunderstanding. He also couldn't wait to meet with her. As he was about to sneak out, Finn looked up to their bedroom and said to himself, "Sorry Jake, but I need to do this..."

In a not too far off distance of the tree fort, a mysterious person looked upon the young hero leaving his home in the dead of night. The person grinned as Finn had soon disappeared from sight and said,"What a perfect chance. I think I'll take advantage of this his and spread some chaos" As the person had finished saying this and began laughing, the moonlight soon revealed the person to look and sound exactly like Finn. This doppelganger's menacing laugh continued as he went towards the tree fort.

[End prologue]
