Okay, this one is too short to be a good chapter, but it's a build up. The next one is going to start the good writing. Sorry for this one though.

As Finn pretty much prepared to die, the growling became louder and whatever it was pounced onto him, knocking him over on his back. With his eyes closed tightly shut, he thought it was the end. "Go on, do it already!" Finn shouted at whatever it was on top of him. "Wow, you're weenie," a familiar voice said to him. "W-wuh?," Finn blinked open his eyes, only to see a horrific, demonic creature; "Aaaaaaaahhh!," Finn screamed in terror, trying his best to squirm away from out beneath the nightmarish being.
The thing on top of Finn started to laugh however, and this time Finn barely opened his eyes just enough to see what exactly it thing was.
"Ugh, Marceline! What the heck?!," Finn yelled angrily. Marceline, who was crying from how hard she was laughing moments ago, wiped away her tears, "oh man, you should have seen look on your face." She got off of Finn and helped him up. "Oh whatever, you would have done the same thing if you were as scared as I was," Finn said as he brushed himself off. "Uh, no; I don't get scared," Marceline retorted with a smirk on her face. "Whatever."
"So, what are you doing out here so late?,"asked Marceline, looking towards the night sky, "I thought I was the only vampire around here," Marceline smiled as she said this, showing off her fangs in the process. "Um, I was just taking a walk," Finn lied. "At eleven 'o clock at night?," Marceline asked, looking straight at Finn as if she knew he was lying. "Oh yeah, I always like to take walks this late, the night air is nice and cool, it's really relaxing," Finn was desperately trying to convince her that he was just out for a walk, but his body betrayed him.
"Oh my gosh, Finn, are you shivering?!," Marceline flew over to Finn and hugged him tightly, trying to make it so that he wouldn't freeze to death. But it didn't work, her undead body gave off no discernible heat and Finn began to go limp in her arms. "Finn, listen to me! Don't go to sleep, please," she began to fly towards the Candy Kingdom, which was the closest place she knew of that would have some warmth. As she approached the kingdom, she decided it would be best if she went straight to Princess Bubblegum. She flew right into Bubblegum's room through an open window. "Quick Bonnie, we've got to get Finn some help, stat!," Marceline said frantically.
Princess Bubblegum, however, barely noticed what Marceline had said. She had been laying in her bed, relaxing, after an extremely stressing meeting with the Lemongrabs. She had to wear her formal attire, so had thought it would be a good idea to take them off and just lay down. Now, she was standing up, desperately trying to wrap her blankets around her so that Marceline or Finn wouldn't see.
"What are you. . ." Marceline noticed Bubblegum and her fruitless efforts to try to cover herself up. "Oh, I'm sorry, I didn't know you were- Hey! you're wearing your underwear and stuff, stop freaking out and help me with Finn!" "What do you mean help you with F-" Bubblegum notices the slightly blue hero. "Oh my gosh, Finn! Guards, take him to the infirmary now!" as the bananas took Finn off to the infirmary, Marceline glanced at the princess, "You know, you really need to calm down. I thought you were in your birthday suit or something like that." "Marceline, I did not know that Finn was unconscious, if I had known he wasn't able to see me I probably wouldn't have freaked out the way I did," Bubblegum was putting on a gown that was only slightly more comfortable than the clothes she had on before, 'I need some new clothes' she thought. "Oh so what you're saying is that you wouldn't care if I saw you naked?," Marceline said jokingly. "Look, Marceline, you and I both know that he probably wouldn't be able to handle that, he might actually explode." "Yeah, well don't you think one of us should teach him about. . . things? It's not like Jake is going to anytime soon." " Don't you dare do anything without my say, I've been observing him and how he works, but I need more information. Normal humans are very rare, he IS the last one." "Yeah well I might not have been one for a long time, but I DID used to be a human. I think I might know more than you do," Marceline says with her hands on her hips. "The best information is collected firsthand." Marceline waves it off; "That's so stupid and you know it." "Whatever, Marceline. Let's just go see if Finn will be okay," Bubblegum says. "Alright, but this conversation isn't over." And with that, they both walked off to the infirmary.
