Hey sorry I didn't update soon. My computer broke. Well now it's updated.

Disclaimer (cause I almost never do these): I don't own Adventure Time. Or the characters here.

(Finn POV)

"My new name... Fionna." She explained. "Now. Time for my revenge, Finn the Human." She said. She started walking closer to me. I was already backed against the wall and because of all the debris I had nowhere to go. I looked around for help. Jake was beside me but I'm sure Fionna meant to kill us both. Marceline flew towards Fionna and prepared to strike. But before Marceline could swing, she was knocked unconscious by Fionna quickly turning around and punching her. Jake tried to use his stretchy powers to tie her up but she found a pressure point on his arm somewhere and paralyzed him. My sword was in the living room and I had nowhere to go.

"Oh dear glob." I said as Fionna made her way towards me. She stopped right in front of me.

"Hm..." She said. I suspected she was trying to think of the most painful way to kill me. She didn't do anything for a while but when I tried to inch away she slammed her hand against the wall to block me from going further. Then she looked at me seductively.

"Uh oh." I said as she inched closer.

(Marceline POV)

I woke up in a pile of debris and was glad to see the sun hadn't killed me. My hat landed on all of my exposed areas. I sat up, put my hat on, and then held my head.

"Ugh." I said to myself. I also saw Jake wake up from some sort of trance or something.

"Agh!" He said as he fell. "That girl really knows her pressure points!" Jake said.

"She has some damn quick reflexes too." I said, while rubbing my head.

"Oh Glob, Where's Finn?" Jake yelled suddenly. He frantically looked around.

"Can't you sniff him out?" I said calmly. Jake looked at me with an 'oh yeah!' face on.

(Finn POV)

I woke up in the basement of the tree house. My arms and legs were in chains and my hat was gone.

"Ugh... what happened?" I said dizzily. Fionna walked in from the shadows.

"Don't you remember?" She said. Memories of horrible things rushed into my head as she walked to me. Then she forcefully kissed me. The force sent my head against the wall, knocking me unconscious. Again. Yes, again.

(Jake POV)

"Finn's in here!" I said, pointing to the door of the basement. I tried to open it but it was locked from the inside. Key hand wouldn't work. "Wha? But the door I NEVER locked!" I said.

"I guess we'll have to try another way." Marceline said. "Hm... Jake, try to shrink down small enough to fit through the crack in the door on the bottom and then open it from the inside."

"That's brilliant!" I said as I shrunk down. I slid under the door and stood up and grew. I used key hand to open the door and let Marceline in.

"Let's go." She said, wielding her axe bass. We walked down the stairs, expecting to see the worst. But luckily we walked in on Finn hanging from chains, unconscious but alive.

"Oh thank glob!" I said running to Finn. But right as I was about to reach him a voice came from behind me.

"Stop. Right. There." She said.

"Fionna." I said coldly. I turned around and sure enough, Fionna stood right behind me. Before I could react, Fionna quickly grabbed a sword and had it at my neck.

"Ahhh!" I screamed. I struggled to escape but to no avail. Marceline stood there, horrified.

"Alright vampire queen. Don't move or the dog loses his head." She said.

"AHHHH! I LIKE MY HEAD! MARCY DON'T MOOOOVE!" I yelled helplessly. I stared at her with pleading eyes. Marcy didn't move a muscle. Then she opened her mouth.

"Pft. You have us at your mercy and the best threat line thing you can come up with is 'or the dog loses his head? You could have said something better." She said. I felt Fionna tense up. She pressed the sword ever closer to my neck.

"Marcy! Stop you're gonna kill me!" I yelled, horrified. Marcy winked at me but didn't really hint anything.

"Well," She said. And before I knew it, I was on the floor and looking at Fionna hold Marcy with the sword against her throat. "I don't care." She said as she slit Marcy's neck open. I gasped. Thing was... nothing happened. Marcy smiled. Then she bit Fionna's hand, making her let go. Fionna screamed in pain and fell to her knees, clutching her hand. Marceline rushed over to me. She picked me up and rushed over to Finn.

"Use key hand NOW!" She said. I quickly obliged and unlocked all of Finn's chains, catching him as soon as the last one was off. We were about to run out when Fionna stepped in front of the door way. She was laughing.

"Well Well Marceline." She said as she smiled, exposing new fangs. I gasped. "You're plan has backfired hasn't it? You've miserably failed because your bite has made me twice as strong as you. I'm now a vampire and YOU LOST!" She asked menacingly. Marcy smiled right back.

"Nope." She said. Without warning, Marcy grabbed her bass and slammed it into the wooden wall, breaking it into woodchips. Sunlight burst into the room. Marceline was protected by her sunhat and gloves. But Fionna was exposed. She screamed in pain as she shriveled up into dust. A few butterflies and a bunny regenerated from the dust.

"Quick! Before SHE regenerates or something!" I yelled.

"Jake, she can't." Marcy said simply.

"Oh." I said, feeling stupid now. Then Finn started to move.

"Ugh... My head..." He said from my shoulder. I had him slung over my shoulder. "W-where am I?" He asked.

"Finn! It's ok buddy! Fionna's gone now! This time for sure!

"Awesome..." Finn mumbled before slipping back out of consciousness.
