Being undead, Marshal Lee couldn't get sick. It was impossible, the only time he ever remembered being sick, was before he was even turned. Yes that would be weird to see a young baby with two vampire parents but it was the rules of the Vampire Kingdom to be turned when one was entering adulthood. It ensured that no one would die since their body was practically already fully developed. So if there ever was a time that Marshal was sick, it was when he was still young.

If there was one thing he hated about ever being sick, it had to be the symptoms. The vomiting, the sniffling, the stuffy nose, and all the other cursed things you got. The thought of being sick just made him shudder, made him thankful he was already dead so he wouldn't get sick. So one could predict his reaction when his adventuress woke up sniffling.

Marshal opened his eyes groggily, still feeling sleepy due to the fact that it was day. Ever since he fell asleep with Fionna, his internal clock was out of wack, sleeping at night when he should have been sleeping in the morning. He didn't mind it though, whenever he was at home alone, he slept during the day. He sat up and stretched, attempting to somehow force himself awake. As he got up to splash some water on his face, he heard Fionna sniffling.

Turning around, he immediately became defensive, ready to comfort her and possibly destroy whatever caused her to cry. He climbed back in bed, fully awake now, and wrapped an arm around her waist.

"Fi, what's wrong?", he nuzzled into her neck.

When she turned over, Marshal had to withhold a cry of surprise. Fionna was extremely pale and sweaty, her nose was slightly red, and she had a cough.

"'M sick Marsh, I dun like bein' sick", she wheezed. Her throat might also be affected by the sudden sickness, he wasn't sure, he couldn't think straight since he was panicking.

"Marsh, hold me closer? 'M cold". She nuzzled into his chest and began to shiver. Marshal managed to hold her tighly against him despite his urge to get away.

He knew he couldn't get sick, but it still didn't make him cautious. He didn't want to be holding her when she began to spew chunks, if she did that is. The only reason Marshal didn't just up and leave though, was because he knew she needed him to be by her side, to help her get better, and that's exactly what Marshal was going to do.

He made sure the fur covers were over them and held he as close as he could. He kissed her forehead and was glad to see her look up and smile.

She moved up to kiss his lips and Marshal hesitated for a split second before meeting her lips. With that done, they both found themselves engulfed by sleep.

Marshal's arm reached over to pull Fionna closer when he felt something, well it's what he didn't feel, and that was Fionna. He bolted up and rubbed his eyes, then checked again and sure enough, Fionna wasn't there.

It was then he heard the toilet flush and he froze in place. He tried not to think about whether or not Fionna was throwing up at that moment, but he couldn't help it. Minutes passed before he regained his composure, and soon he was floating over to the restroom. When he got there though, Fionna was nowhere to be found. He figured that she must have left while he was busy trying not to lose his nerves.

Marshal floated over to the living room and spotted a note on the couch. He picked it up and read,

Dear Marshal,

Went out to get some tea leaves and other junk for Fionna. Be back soon.

-Cake

He smiled and was thankful that Cake could at least go out and get the things Fionna needed. That however, still didn't explain where the blondie was. Marshal began to get concerned when a sudden crash in the kitchen startled him.

He slowly walked in to find Fionna mumbling to herself. She appeared to be in a daze and it took a second for Marshal to process the scene.

She was in her bra, just her bra and her black shorts. It appeared that she had dropped a jar of some sort, and she just looked so lost with her eyes half closed. Marshal couldn't help but hitch a breath as her bare feet almost stepped on the broken glass, but, by some miracle, she stepped over it. That meant that she was at least aware of her surroundings, or at least somewhat aware.

He moved closer and turned her around gently and carefully, not wanting to upset her stomach in any way.

"Fi, can you hear me?". He waited until he got a very faint 'mmhmm' from her before he led her to one of the chairs and made her sit. "Puff, whatarya doin'? You're sick you shouldn't be up right now". He pressed his hand against her forehead and stared at her in a wide-eyed surprise. She was burning up to a violent degree, he felt like she would end up passing out at any moment.

The vampire moved to the sink and ran a towel under cool water. When he returned, he placed it on her forehead in an attempt to cool her down. It was something his parents always did to him when he had a fever.

"Whatara doin' here babe?". He had to wait for her to process his words, and finally got a mumbled answer, "Well..'m hungry...and..'m hungry...and 'm hot". He half grinned at how delirious she was, he knew the fever was getting to her. "Come on, let's go back up". He helped her up and guided her back to the room where he made sure she lied down. When he knew that she was tucked in, he left to bring a bucket of water and more towels. He couldn't help but smile at the fact that he could actually use this against her. Of course, Marshal wasn't that mean...right?

Thanks to the tea that Cake had made though, and the fact that Marshal stayed over until she was completely cured, Fionna was feeling better in a couple of days. That however, didn't stop Marshal from keeping her in bed.

"Marshal, let's go adventuring", she pouted, as Marshal kept his leg thrown over hers. He let out a growl and placed his hand on her forehead. "Nah, we can't you still have a fever".

"No I don't, you're just saying that cuz you're feeling lazy"
"No, you actually still have a fever"
"Marshal Lee, if you don't let me go this instant, so help me I'll-"
"Quiet puff, you're interrupting cuddles"

And with that, Marshal Lee silenced Fionna. Well, almost silenced, he couldn't stop the fit of giggles Fionna had due to his words.
