Pairing: Finneline, minor Flamin (Flame Princess and Finn)

Song: Better than Revenge by Taylor Swift

Requested by: RandomFanPerson

Disclaimer: Adventure Time and the song aren't mine.

"Hey, Finn. Wanna come over for movie night?" I said. Finn shook his head. "Sorry, I'm going to dinner with FP. Maybe some other time?" he replied.

I rolled my eyes. Ever since Finn and Flame Princess started dating, he's rarely with me to write songs. And if he does come, it's with her.

"How about you bring her to my place? We can all have dinner together," I tried. Finn shrugged. "Sure. I'll tell her. See you later."

He stood up and left. I raced back to my house and started to write a song. "This is going to be perfect," I snarled.

That night, pizza and soda were littered around my table. We all laughed and junk.

"Oh! I almost forgot. I wrote a song for you, FP," I said. She looked at me. "Can I hear it, Marceline?" she asked. I nodded and got my bass.

The story starts when it was hot and it was summer
And I had it all, I had him right there where I wanted him
She came along, got him alone, and let's hear the applause
She took him faster than you can say sabotage

I never saw it coming, wouldn't have suspected it
I underestimated just who I was dealing with
She had to know the pain was beating on me like a drum
She underestimated just who she was stealing from

Flame Princess blushed and scowled at me. Finn widened his eyes. I turned to him.

She's not a saint, and she's not what you think
She's an actress, whoa
She's better known for the things that she does
On the mattress, whoa

Soon she's gonna find stealing other people's toys
On the playground won't make you many friends
She should keep in mind, she should keep in mind
There is nothing I do better than revenge, ha

She lives her life like it's a party and she's on the list
She looks at me like I'm a trend and she's so over it
I think her ever present frown is a little troubling
She thinks I'm psycho 'cause I like to rhyme her name with things but

Finn looked at FP. She smiled nervously. Looks like the cat's out of the bag, now. I remembered all those times she stuck her tongue out at me or shoved me or even tried to spill water on me to make it look like I wet myself in front of Finn. I turned to her.

Sophistication isn't what you wear or who you know
Or pushing people down to get you where you wanna go
Oh, they didn't teach you that in prep school, so it's up to me
But no amount of vintage dresses gives you dignity

She's not a saint, and she's not what you think
She's an actress, whoa
She's better known for the things that she does
On the mattress, whoa

Soon she's gonna find stealing other people's toys
On the playground won't make you many friends
She should keep in mind, she should keep in mind
There is nothing I do better than revenge, ha

I looked at Flame Princess, triumphantly smirking.

I'm just another thing for you to roll your eyes at, honey
You might have him, but haven't you heard?
I'm just another thing for you to roll your eyes at, honey
You might have him, but I always get the last word

She's not a saint, and she's not what you think
She's an actress, whoa
She's better known for the things that she does
On the mattress, whoa

Soon she's gonna find stealing other people's toys
On the playground won't make you many friends
She should keep in mind, she should keep in mind
There is nothing I do better than revenge, ha

And do you still feel like you know what you're doing?
'Cause I don't think you do, oh
Do you still feel like you know what you're doing?
I don't think you do, I don't think you do

By now, Finn was inching away from Flame Princess, horrified. I smiled.

Let's hear the applause
C'mon show me how much better you are
See you deserve some applause
'Cause you're so much better
She took him faster than you can say sabotage

I floated down to the floor. FP was angry. Fire sputtered around her. "You embarrassed me in front of my boyfriend, Marceline! I hate you!" she yelled. She turned to Finn, and she simmered down. "Finn, none of that is true, I swear!"

Finn shook his head and pushed her away from him. "Marceline only sings the truth. And from what I heard, you've done nothing nice at all. We're through!" he shouted.

Flame Princess snorted and headed for the door. "Whatever. You're not worthy of me anyway, Finn!" She slammed the door behind her.

Finn slumped on the couch. He winced. "I forgot how uncomfortable this was," he exclaimed. I sat beside him. "You get used to it."

"Hey, Marceline."

"Yes, Finn?"

"Wanna go out sometime?"

Revieweth, pleaseth! Oh, I take requestes! :)
