Fionna stood up and looked into the mirror.

"Really?" She asked excitedly, examining her teeth inside her reflection.

"Fionna this isn't funny! Look what that evil boy did to you!" Cake screamed. Fionna started to get extremely angry. Not only did she lose all fear of becoming a vampire, but she now was so mad that she wanted to go stay at Marshall's and get used to her new life, just out of resent towards Cake.

"I'm going to Marshall's. I'll be back when you learn to accept the fact that I make my own decisions now," Fionna sneered angrily. Without even looking back at Cake, she stormed downstairs and started out the door to Marshall's house. She wondered if she would be able to fly now, but decided that she'd let him teach her first, just in case. She arrived at his doorstep later on, knocking heavily against his door. "Marshall?" She yelled. After roughly a minute of knocking on his door, it finally opened up and revealed Marshall's figure to her. He was dressed only in his boxers and an undershirt; his eyes swollen and red, and teeth stained slightly with blood.

"Oh... Fionna, why are you here?" He asked, clearly sounding run-down and tired. Fionna could tell he was upset about what had just happened, but opened her mouth and showed her fangs to him.

"Look! Look, Marshall!" She shouted excitedly.

His lips parted into a small smile, and he pulled her into a warm hug, running his fingers through her hair gently.

"I'm so sorry, Fionna," He whispered. "This is all my fault,"

She shook her head looked up at him. "Not at all. I'm so happy! I want to be with you forever; I love you Marshall," She said, gazing into his eyes. His grip around her waist grew tighter, and he rested his head against her.

"I love you too, Fi," He smiled.

"Can you teach me how to fly?" She asked. Marshall nodded and shut the door behind him.

"Tomorrow though, it's getting late and you need your sleep," He murmured. Picking her up and floating over to his bed, he placed her down and covered her with blankets. He then pulled off his shirt and slipped into bed beside her, wrapping his arms around her gently. His lips met her forehead several times before reaching over to grab her hand, leaving not a centimeter of space between him and Fionna. She soon fell asleep, her face nuzzled into the crook of his neck; hand clasped in his. "I love you," He kept repeating to her dreaming body. Something about Fionna opened up a completely different side to Marshall. A soft, sweet and caring side; a side that makes him open to revealing his vulnerability to Fionna. The next morning, Marshall awoke to find himself alone in bed. "Fionna?" He called out into his empty home. He got out of bed and looked around his house for her, in every room possible. She was nowhere. Figuring that she probably went back to the treehouse, he got dressed and flew over to her place. After knocking on the door a couple times, Cake opened the door, and rolled her eyes.

"I don't know what you want, but she's not here," She scoffed before slamming the door in his face. Where was she? Marshall was beginning to worry. He began thinking of places that she could be, and came to the conclusion that Prince Gumball may have some sort of involvement in this. He quickly made his way to his castle, and slipped in through an open window. When he found Gumball, he pulled him up by the shirt and directed his red eyes toward PG.

"I know you have her, Gumwad," He taunted. Gumball just rolled his eyes.

"Yeah, I do. I needed to talk to her about this whole thing going on between you two. What is it? Are you guys together- or what?" He asked, "And I won't leave her alone until we solve this the right way," He added.

"Oh, and what is that?" Marshall laughed.

"A fight," PG replied. Marshall fell onto the floor and started laughing jokingly.

"Oh, okay Gumwad. If that's what you want," He giggled, "I'll try my best not to kill you,"

Fionna came and stood between the two.

"I don't want you guys fighting over me.." Fionna complained. "I get to choose who I like," She looked up at Marshall and put her hands on his chest. "Please, don't hurt him. Just let it be," she pleaded. Marshall smirked and nodded. He leaned in and kissed her gently on the lips.

Gumball was getting mad, though.

"So what are you two then!?" He asked. "And don't be making out in front of me, either,"

"Dude, just leave us alone!" Marshall hissed, pushing Gumball onto the ground. He grabbed Fionna and flew back to his house. "Glob, Fionna," He sighed. "I'm sick of all of this. I just want to be with you baby," He murmured, laying onto the bed and pulling her beside him.

"Marshalll!" She complained. "You took me here without even asking," she added, sighing.

"So? You'd rather be with that candy freak?" He asked. "Just stay here with me for a while, please," he mumbled, kissing her cheek. "Just let me hold you,"

Fionna nodded and made herself comfortable in his arms. "Won't your mom kill you?" She asked. "I mean, you're not as... evil as you used to be,"

"It's your fault," He laughed. "Whatever. I'm not going to let anything separate us," He added.

Fionna blushed and pulled the blankets over top of them. She snuggled close to him, and reached her hand down, unzipping his pants.

"Fionna what are you-"

She placed a finger on his lips, and pulled down his boxers, stroking him gently. He then pulled her skirt up and removed her panties, and entered inside of her. She looked back at him and smiled, holding his hand tightly. He continued moving in and out of her at a slow pace, kissing her neck and her shoulder repeatedly. She watched as he closed his eyes, making it look like he was in complete bliss. Pulling her face towards his, he gazed into her eyes lovingly and pulled out, releasing himself onto her lower back. "Fuck, Fionna, I love you..." He whispered.

"I love you too, Marshall. I'm so in love with you," She cooed.

He rolled over onto his back and stared at the ceiling.

"I'm going to a party tonight, wanna come?" He asked.

She nodded excitedly. "Of course! Just don't get so... drunk like you did last time," She laughed.

"I don't think I remember that time," He teased.

"Shut up," she giggled as she pushed him off the bed playfully.

"We should get you something sexy to wear," he smirked.

"Yeah sure, as long as you dress up too," She replied. "But can you teach me how to fly first?"

Marshall got excited when she reminded him. "Yes!" He smiled. A few minutes later, he was standing on the edge of a high cliff with her, trying to explain how to fly properly. "Okay, so it's mostly about keeping a steady and consistent balance..." He started. "You just have to jump off the ground slightly then focus on keeping steady the whole time... like this," He taught, as he flew high up off the ground, looking at her from above.

"Like this, Marshall?" She yelled up at him, as she jumped up. She managed to keep her balance for a couple seconds, but got sidetracked looking up at Marshall and became unsteady, slipping off the side of the cliff.

"FIONNA!" Marshall screamed; probably loud enough for all of Aaa to hear.
