Just a reminder, Finn is 20 years old here.
"Ok Finn, all you need to do is..." Marceline started.
"I know," Finn said.
Finn clenched his fists.
"I never wanted you to be in my mind,
But you cracked up my senses and made me go blind,
You promised me that you'll be kind
Now it's like you and me combined.
I hated you but you made me see,
What I can really be,
So come on don't be afraid
Yeah, come on let's trade." Finn said to himself slowly.
Finn turned into a bat like monster.
"Wow, Finn!" Marceline cheered.
Finn looked at Marceline. He's eyes were red. Blood red. He grabbed Marceline by the waist and screamed.
"Never escape."
Finn reverted back to vampire form. Half of his hair was black and the rest was blonde. His fangs were longer. Marceline was shocked. Finn wasn't Finn anymore.
"Vampire King!" Marceline gasped.
"Yes, Marceline. You're correct. I AM the Vampire King!" The Vampire King said.
"What have you done to Finn?! You monster!" Marceline screamed freeing herself.
"Muahhh... Finn's no longer here..."
Marceline's eyes started to well up.
"Finn..." Marceline sobbed.
"Finn? You have me! I made you a vampire, I made YOU my queen! So YOU should be MINE" Vampire King bellowed.
Marshall attacked Marceline but she easily dodged it.
"You killed, Finn!" Marceline screamed.
She uprooted a tree and swung it at Marshall, the Vampire King.
"Woah, easy Marcy... You know who'll win at the end... And it's ME!" Marshall said punching Marceline.
Marshall made Marceline go numb with his powers.
"Any last words, Marceline?!"
"Yeah... It's a song... for Finn,
From the fi-rst hi,
To the fi-rst bye,
I al-ready fell in love wi-th you,
From the first light
To the first night,
I already fell in love with you,
Oh you, yes you.
From the first wait,
To the first 'You're late!'
I already fell in love with you,
From the first week,
To the first year,
I already fell in love with you.
So please don't leave me baby...
And you might think I'm crazy...
Yes I'm in love with you,
And I'm not afraid to let it show.
Yeah I'm in love with you
And I'm gonna let this love grow,
Yes I'm in love with you,
And I'm not gonna let you go...
Now go kill me..." Marceline sang.
The eyes reverted back to normal. Not red anymore... Finn was Finn again.
"Marceline... I'm sorry... I... I didn't know." Finn said.
His hair slowly reverted back to normal. Marceline's numbness disappeared. She hugged Finn.
"Marceline do me a favour will ya?"
"Ok..." Marceline agreed, still scared.
"Lock me up in a cage I can't escape until you can find a cure for my vampirism,"
"You sure? It'll be lonely, and I don't want my bat to be lonely."
"My bat, that's new... anyways just do what I say, quick. Before he comes back..."
