Even though it was short, the episode was AMAZING! My friend and I were texting one another back and forth, fangirling. I know when I see her at school tomorrow, it'll be even better since we'll be jumping up and down and basically crying tears of joy for our love of Marshall Lee.

So this chapter is the last one. I know, I'm sorry. But I'm going to move onto a new story I'm in the process of writing. It's another Adventure Time story and I'll be having a poll on my profile in a few hours or so about what you want it to be. Either Fionna and Cake or Finn and Jake. You pick and then I'll write it. The story can go either way. I'm also taking requests for oneshots or something. Just let me know, everyone!

There's one song in this but it's previously sung so... I'm no longer taking entries for this story. Sorry.

And guys, you broke the review record. This story is the highest reviewed of any of my other stories. Thank you all so much!

He took in a deep breath, hesitating at the door. Marshall then pushed it open and entered the prison room of the Nightosphere. Ashley was slumped in her cage, looking down at the ground. When she heard his footsteps, she looked up and saw him approach her. His expression was unreadable. There was no pity or apology. He was blank and almost bored. She smiled at him as he stopped a few feet away from the bars.

"Marshall Lee the Vampire King. I should consider myself honored that you've come to visit me," Ashley said.

"This place is too good for you," he said, observing the prison around them. "I surprised my mother didn't toss you into the eternal fire."

"I'm deathless, Marshall. She couldn't kill me if she tried."

"Who said anything about killing?"

Her jaw clenched as she glared at him. "What do you want?"

"I've just come to check and see if the magic draining is working. Since you haven't broken out, I think that's a good sign."

She laughed airily. "Yes. Heather is taking plenty of precautions to make sure I don't escape. I can't even conjure up a simple spell."

"That was a terrible thing you did," Marshall said darkly. "Nearly killing me and trying to kill Fionna. You have gone insane."

"You really think you've won?"

"Yeah. I do."

"She's a human, Marshall. She's going to die some day."

"If you lay one finger-."

"Not by my hand, you moron. Humans die. You know that, I know that. Even her cat knows that Fionna will die. The cat will die too. She's not immortal either."

Marshall knew that Fionna wasn't going to live forever but he didn't care. Fionna was tough enough to withstand anything and outlive everyone. Besides, Marshall aged too but his demon blood made it slow. Biologically, he appeared to be at least sixteen. Chronologically, he was over one thousand years old. But Ashley thought she was the winner. Marshall cracked a grin, which made her frown and glare at him.

"I hope you enjoy your time in here," he said, turning away. "You don't deserve it."

Ashley said nothing as he walked out of the prison and returned to the portal back to Aaa. He was transported back to the Tree Fort where Fionna was sitting, waiting for him. She looked up as he sealed the crack in the trunk behind him and turned to look at Fionna.

"How is she?" she asked him.

"Stuck with no where to go," Marshall said. "Ashley won't be bothering us anymore."

Fionna nodded. "I'm just glad you're okay. You almost died from the sunlight back there."

"I know but I'm fine," he promised. "I'll meet you at the party in the forest tonight. It's casual so don't worry about dressing up in a dress or anything."

"I'll see you tonight!" she agreed, watching him open an umbrella and flying home. Cake walked downstairs, her dulcimer on her back.

"Where are you going?" Fionna asked her.

"I'm going over to Mocro's to practice dulcimer," Cake replied. "I'll see you at the party, girl! Have fun!"

"What am I supposed to do for the next five hours?" Fionna demanded.

"I don't know! Play BMO or something. Visit Gumball for all I care. I've been waiting for a date with my man for a while," Cake said, jumping outside and leaving Fionna behind. With a sigh, Fionna called BMO and it waddled over to her, ready to be played. After about an hour, Fionna got bored of the game and left the treehouse, hoping to catch wind of a dungeon or monster. Even Ice Queen capturing a Prince would be entertaining to say the least. But Fionna found nothing that could satisfy her thirst for adventure. Aaa was strangely quiet and it bothered her. She was used to things jumping out at her and asking her to fight. Not that she didn't enjoy peace and quiet. She did but she preferred a little more action in her life. That was just how she was driven, how she spent her life. It was just a natural instinct to her.

Fionna trudged around the grasslands, her hands over the hilt of her sword, looking to slay some monstrous beast who dared to cross her path. Instead, her legs carried her to her favorite tree. The lone tree in the clearing that always stood waiting for her to climb it, to appreciate it. Fionna stepped up, sitting on its branch and leaned on the trunk, looking up at the leaves that sheltered her from the sun. She thought about how lucky she was to have such an amazing life here in Aaa. Lucky that she was born during this time instead of years ago during the war. Lucky that she was able to know Gumball, Marshall, Cake, Flame Prince, BMO, LSP, and so many more. Lucky that she was a hero.

Even though she was sometimes bothered by the fact she was the only human in known existence, she thought about how the world around her seemed more natural without other humans. Fionna sighed and closed her eyes, listening to the sounds of the forest with a gentle smile.

Her thoughts trailed off to Marshall Lee in general. How she wanted to tell him of her affections. That she loved him with all her heart. That she's never felt like this about any guy she's ever liked. Marshall had become her world and, even though he could outlive her, she'd still hold onto his heart and give him all of her love. Even if her greatest fears were realized and he didn't love her back, she would still want to remain friends with him. That would be the worst part about admitting her feelings, like she had once stated in a song. It was a sacrifce that wasn't fair.

She spent quite a while just sitting there and dwelling on her love for the Vampire King before she found that it was time to go to the party. Lumpy Space Prince was throwing one for no apparent reason but it was going to be fun. So Fionna jumped down from her tree, patted its trunk, and ran off deeper into the forest to one of its many clearings. She knew where it was since she heard music playing from an old boom box that LSP owned.

Night had fallen by now and it was in the same location as Marshall's jam session. The only difference was that there were more people and the stage was gone. Cake was there with Lord Monochromicorn and Prince Gumball, who waved at her to join them. She smiled and was about to but Marshall Lee stopped her by grabbing her shoulders. He gave an apologetic smile to their friends and turned Fionna around to face him.

"Nice of you to show up," Fionna said with a smile.

"You knew I was coming," he said.

She shrugged and dragged him over to their friends. They sat together and enjoyed each other's company, watching the party-goers go on about their business. Some began to dance and Marshall invited Fionna to dance with him. She took his hand and they walked off to dance together beneath the moonlight.

"Marshall?" she said after a while, looking up at him as they swayed on the spot.

"Yeah?" he said.

"Can you sing our song?" she asked with a shy smile.

He leaned his forehead onto hers and grinned. "Only if you sing it with me."

She nodded and he began to gently sing in her ear. Fionna began to "Aaaa" quietly as he sang to her.

Good little girl

Always picking a fight with me

You know that I'm bad

But you're spending the night with me

What do you want from my world?

You're a good little girl.

She pulled him closer, resting her head on his shoulder and she sang, Marshall softly "Aaaa-ing" along with the song.

Bad little boy

That's what you're acting like

I really don't buy

That you're that kind of guy

And if you are

Why do you want to hang out with me?

He chuckled and rapped, toying with her hair.

Don't you know I'm a villain?

Every night I'm out killing

Sending everyone running like children

I know why you're mad at me

I've got demon eyes

And they're looking right through your anatomy

Into your deepest fears

Baby, I'm not from here

I'm from the Nightosphere

To me you're clear- transparent

You've gotta thing for me, girl

It's apparent

They both began to laugh together, Marshall Lee twirling her around. He looked about the party, noticing that no one was paying any attention to them.

"Let's get out of here," he said.

"Sure," she agreed, letting him pick her up and fly her away to a plain, dirt area where they sat atop of an old mobile home. Fionna leaned on him and he wrapped his arm around her shoulders, the party just barely visible from where they sat.

"It's so strange. Months ago, you and I were singing that exact same song together in that very same clearing," Fionna said.

He nodded. "Time sure flies fast."

"A whole lotta junk happened through that time."

"Yeah. A whole bunch a' stuff."

They sat in silence for a while as the party raged on without them. Their eyes were upturned at the stars, winking at them from above with a warmth they could feel from all the way from the Earth. It was a soft , calming feeling that made the two of them relax with one another faster than ever before. A peaceful, loving moment that the two of them were blessed to share. Fionna felt like Marshall wanted to tell her something but was holding back. She glanced up at him and he noticed her stare. He looked down at her, eyebrow raised.

"What?" he demanded.

"Is there something you wanna say?" she pressed.

He was slightly taken aback by this but realized that he was thinking about telling her that he loved her. After that whole mess with Ashley, he wanted nothing more than to let Fionna know that everything was going to be fine between the two of them. There was a long pause as Marshall contemplated how he could put his feelings towards Fionna into words.

"Yeah... I do," he said. "But it's not easy to say and never gets easy to say. No matter how long you've lived, you can't just throw these words around like play things."

Fionna felt her face warm up, realizing how deep he was getting into this. She didn't say anything and let him continue. He took in a deep breath and tightened his grip on her shoulders.

"Remember this, though. No matter how old you get or how much we fight or whatever, I'll always mean these words, Fionna. I'm not perfect. I'm the son of a demon and a bad guy. The villain in every scary movie imaginable," he said, trailing off a little.

"Marshall?" Fionna said, egging him to go on.

He smiled, thinking about how cheesy he sounded. "Oh, nuts that was stupid," he said, laughing.

"No! It was cute!" Fionna promised but that only made him laugh harder.

"I'm sorry that I sounded like a total dope," he said, regaining his breath. "But if you like it, hey. Whatever."

"Go on! Or was that all you had to say?"

"No... I wasn't done."

"Then finish. I wanna hear what was on your mind."

"Usually you say 'penny for your thoughts'."

"Yeah, well, I don't have a penny with me."

"Alright, alright. Lemme go on." He took in a deep breath and went on with his little monolouge. "Fionna, I guess the only way I can put any of this garb into words is if I actually say what I've been procrastinating to say-."

"Spit it out," Fionna said, giggling and punching him in the arm lightly. "Before you bore me to death."

Marshall grinned and looked her in the eyes, red clashing with blue.

"I love you, Fionna," he said, making her smile vanish out of surprise and her face glow with embarrassment.

"You do?" she whispered.

He nodded. "A whole heck of a lot."

She closed her eyes and smiled, a single tear of joy slipping down her cheek. "Marshall Lee... I love you too. And you have no idea how long I've been waiting to say that... to hear that."

"Why didn't you?" he questioned.

"Because I didn't wanna lose you as my friend," she explained, wiping away the tear. "That was something I never wanted to experience."

"Well don't worry about it anymore, Fionna," he promised, kissing her cheek. "I won't be leaving you as a boyfriend, let alone a friend, any time soon. I swear."

"That's good to hear," she said, smiling at him. She poked him in the chest and her smile turned into a smirk. "But don't expect any of this lovey-dovey stuff to change me or us in general."

"How do you mean?" he said, smirking too and raising an eyebrow.

"I still want to play fight, adventure with you and Cake, goof off and embarrass Gumball sometimes, jam with you and our friends, and still be your best friend," she explained. "I don't just wanna be your girlfriend. I'm not that kind of girl."

He grinned, flashing his fangs at her. "Oh don't you worry! Nothing's gonna change there. I know exactly what you're like." Then his smile softened a little, making sure to add on a little something and get his point across to her about how much he cared. "But at the end of the day, I'll always be there to say that I love you."

"I'm counting on you, dude," Fionna said, standing up from her spot.

"I won't let you down," he said, standing up too.

"Cool. Well then, I guess it's time," she said.

"For what? The party isn't over," he said, peering over at their friends who were still cheering in the clearing. Then he felt himself get pushed over and heard Fionna laughing as she jumped off the trailer.

"You're it, man!" Fionna yelled after him.

Marshall began to laugh too and leapt off the mobile home to chase his girlfriend down. The two of them spent the rest of the night playing tag and getting everyone else to join in on the fun. After the party, Marshall and Monochromicorn dropped their girlfriends off at their home. And, like Marshall promised Fionna, he told her that he loved her before flying off into the sun rise, leaving her breathless, smiling all the while.

"The End," Marceline said, closing the book.

"Oh... my Glob! Marcy, that was great!" Finn said, clapping his hands.

"Great story," Jake said, nodding approvingly.

Raincorn was translated to say, "I loved that! Can I get a copy?"

"I really enjoyed it, Marceline," Bubblegum said earnestly. "Good job."

"It was so amazing," BMO said.

"Well... it was lumping incredible," LSP admitted, crossing her arms.

They looked at Ice King, expecting him to have some sort of outburst but his cage was empty and Gunter was gone.

"Oh what!?" Finn said, running to the Tree Fort's window and spying Ice King running away. "Dude! That's just lame!"

"Relax, Finn. He was just intimidated by my skills," Marceline said with a smile.

"So there's no more?" Jake said, frowning a little.

"Sorry guys. But hey, you can always reread the story. It'll always be here for you. A little piece of Fionna and Cake in Ooo," Marceline promised, floating up and placing the book on Finn and Jake's bookshelf.

They all bid one another goodbye and returned to their homes after a nice night of reading Marceline's fan fiction. When Finn was alone, Jake going to take a shower, he took down the book and went into the bedroom to reread his gender-swaped adventures. Even though he knew what was in store for Fionna, he couldn't help but feeling that every time he was going to read this, her adventure was going to start all over again.

And that's a wrap! I hope you all enjoyed reading my story as much as I enjoyed writting it. There's more Adventure Time in store so be sure to check out my proflie for the poll titled Next Adventure Time Story: and then the two options (Fionna and Cake) or (Finn and Jake).
