A/N: Sorry, guys! I pulled a fast one on you. I uploaded both chapter 4 and 5 at the same time. Also I re-uploaded chapter 5 as it was unfinished.

Fionna clutched her sword as she tried to fall asleep and felt the roots of the walls and floor of the room come to life around her. With added concentration she could feel a dresser, other unidentifiable furniture, and a lump on the floor. A heartbeat radiated from the form, and Fionna squeezed the sword as she realized she was feeling his heartbeat through the floor. Holding on tightly to the Banisher of Evil, with the pitter patter against her palm, Fionna slowly fell asleep.

The heartbeat quivered in her palm, and something like an electric shock struck her hand. It thrust her awake.

"Ah!" She gasped, releasing the hilt. The sword vibrated strangely on her side, and Fionna saw for the first time since yesterday, the hint of light. A flash of light immitted from the sword, and it connected straight to the shaking form of Nemo on the floor.

"What the glob?" She gasped, pushing against the headboard. Another flash of light, and his form rose from the prone position of sleep. Another flash, and he was revealed to her. The familiar, friendly face that she knew so well was twisted in some sort of unrest.

It was Marshall Lee. But his eyes were bright red, and… wrong. Something was wrong. The sword shivered at her hip, as if seeking to bury itself in his chest.

"No!" She told it, and grabbed the hilt despite the shock of electrocution she felt race through her body. His red eyes snapped towards her, and his form grew grotesque in the dark, rising in inches and guttural growls. Holding on tightly to the sword she held it defensively across her body.

"Snap out of it, Marshall!" She screamed at him. It felt strange to use his name. This wasn't the Marshall she knew. He had never been… so terrifying. The beast might as well have not heard her and it bounded towards her. Red eyes approaching hers in a thunderous speed, but stopped just before her. The sword shook and shocked the creature, every move closer emitting a flash of light that beheld the mutilated form of her friend. His teeth were needle sharp daggers, dripping, and hungry. His face was barely recognizable. If Fionna had not witnessed his bat form she would never have been able to associate the two.

"M-Marshall?!" She called to him, watching him fight against the barrier the sword provided her, chomping, snarling, towards her. What had he become, and why?

"S-stop it!" She screamed, pushing the sword towards him. The blade grazed him, just a slice, and he was struck with a bolt so powerful that Marshall was thrown to the other side of the room.

Then everything was quiet, save for the desperate breathings coming from the other side of the room. The sword was quiet now, as well and she shakily put it back in her makeshift sheath.

"M-Marshall?" She called again, now scrambling off of the bed towards the place where he had fallen. She felt his form, and it was humanoid again, but hot to the touch. Fionna shook him, and he did not respond.

"Hey! Wake up!" She screamed at him, but still he didn't stir. Her hand found his neck, and his pulse raced beside it. She didn't even know that vampires had a pulse. Fionna didn't know what to do, so she felt for his chest and began thrusting pumps into him. Every hero knew their CPR… but did he eve have a heart to resuscitate? Feeling his face with her hands she pinched his nose and held his chin up.

A stupid thought passed through her mind.

She was about to kiss Marshall Lee. She groaned at her inner thought and pressed her face to his, pushing a big breath down his tubes. The moment her face touched his, a residual shock from the sword, or possibly static from the air, jolted him awake.

He gasped against her face, and she fell backwards, immediately embarrassed.

"Wh-what are you doing?" He asked, his eyes silver and shining once more. "Did you just kiss me?"

"No… not really." Fionna responded, feeling the adrenaline of the altercation start to diffuse. Geez, what was up with him? Didn't he remember turning into that… thing? Maybe this was what he had warned her about before.

"What happened?" He asked.

"I think… you know what happened…" she said through slanted eyes. He sighed and held a prolonged silenced watching her cautiously in the dark.

"I turned…?" He inquired. She nodded slowly. Marshall buried his palms into his eyes. What was he doing, letting her stay here?

"Did you… are you okay?" He said, voice quivering. "I told you I was a monster." He whispered through a knot in his throat. Fionna felt for him in the dark, and pulled him towards her in a heartfelt embrace.

"You're not a monster…" She said to him. He held her firmly in his arms, and Fionna could feel his head bury itself in her shoulder. "Is this what you were afraid of yesterday? I held my own, see? I didn't lose my sword…"

"You should leave…" He suggested.

"No." Fionna responded.

A huge part of him screamed to push her away for her own sake, but he couldn't deny her company for his own. And if she wanted to stay… after seeing him like this, how could he deny her? He couldn't. He hadn't the strength.

"…Okay." He said.

Fionna let out a huge yawn. Now that the danger was over, her previously sleepiness began to overwhelm her again.

"Do you mind if we go back to bed?" She asked, her eyes shrinking closed.

"Sure" He said half-heartedly, but did not release her from their embrace. Marshall was horrified at imagining what she had experienced. What had he done… what had instigated it? Lately he was scared of himself, and felt foolishly irresponsibly for bringing Fionna into this. He didn't even dare to think of what would happen should she find out who he was, what betrayal she would feel… and what of their strange almost kiss earlier? This could only end badly.

Fionna's body went slack against his, and Marshall heard little snores in his ears. She had fallen asleep sitting up! He was a bit gloating as he realized she had fallen in his arms. She couldn't truly be afraid of him if she conked out on him… What idiot falls asleep on a monster like this?

Feeling a bit sore from his midnight ordeal, Marshall carried Fionna back to bed, and tucked her in. He chuckled, thinking she would have hated knowing she had been tucked.

He laid next to her and stared at the ceiling, falling back into his old habit of feeling sorry for himself and wishing he did not exist, but the snoring girl next to him kept distracting him from those thoughts. Marshall closed his eyes and remembered the way her face had felt against his. That was a moment which would probably never repeat itself. He could die happy now, he thought as he fell back asleep.
