Alright people, it's a little late and I apologize. I'm trying to space this out on uploads so I don't finish so soon. Plus I am a procrastinator and typing is sooooo hard to start.
Well… Let's get started on THIS chapter. Here it is…

Marshall watched as Fionna jumped down the ladder and left to see Flame Prince. He was happy she said bye, but he wished she's just stay with him. His smile became a frown and a sigh left his body.
"So you do really like her, huh?"
Marshall jumped. He turned to see Cake, arms crossed, staring at him. She raised an eyebrow at him.
"I do, but like you said… We wouldn't work. I'd outlive her and I could never turn her. She means too much to me."
Cake smiled at him "I'm glad you understand Marshall, and I'm sorry I said that. I know it had to sting a little."
"It did, but the truth rarely ever makes someone truly happy." Marshall walked to the window and looked out. "Hey… Hot Head is here… he's out there talking to Fi."
Cake stretched over and stared down at the two teens talking.
"Wonder what they're saying." Cake opened the window and listened.
She could faintly hear what they were saying, but Marshall heard every word. From what he picked up Fionna was making him angrier and angrier.
Cake looked at Marshall. "You can hear them can't you? With your supa hearing."
Marshall shot a look at her. "Yes, now shhhhh." He closed his eyes again and focused in on them.
"What's going on, Marshall? Tell me!" Cake jumped on Marshall's head.
"Glob Cake! Fine. Fionna is told him I came over last night and… he is not happy." Marshall could hear his flames crackling more.
Cake put her hands on her mouth. "Oh… Girl is digging a hole she can't fill."
Marshall chuckled. "Fill her…"
Cake slapped him. "Shut yo face you perv!"
Marshall rubbed his face and laughed. "Deserved it... but worth it. Alright…" He closed his eyes and focused yet again. "Now she told him that I was… still here. Crap."
Cake sighed "That girl… she just can't lie."
Marshall heard Fionna telling Flame Price to go home then it happen.
"Don't turn your back on me!"
Marshall and Cake heard Fionna scream.
"Marshall! What happen?!" Cake jumped off of Marshall's head and looked out the window. She saw Fionna on the ground holding her arm.
"Cake… I need a favor, fast!" Marshall jumped on the window seal. "Get on the roof and block the sun just enough to cover the area around Fionna." Cake looked puzzled. "NOW CAKE! Trust me!"
Cake nodded and ran off to the roof, and Marshall listened to Fionna and Flame Prince's argument again.
"Don't Mock me you liar"
Marshall watched as Flame Prince took Fionna's punch. Marshall rubbed his face "I've been on the end of that once…"
Flame Prince stood back up and back Fionna back against the house. He pulled his fist back. Suddenly a shadow covered them. Marshall's cue to stop this had been signaled. He flew as fast as he could towards Flame Prince. Marshall saw Flame Prince's fist closing the gap between him and Fionna. Marshall stopped next to Flame Prince and put all his force into his hand. Time stood still as Marshall connected with his punch. Then it all rushed back to normal. Marshall exhaled and stared at Flame prince as he rolled a couple yards.
"Marhall…" Fionna said as she put her block down.
"Who else is this sexy?" He chuckled. "Seriously, Fionna, get inside and fix that-"
Flame Prince stood up and screamed at Marshall "YOU BLOOD SUCKING FREAK!" He rubbed his face. "How dare you punch me in the face!"
Marshall rubbed his burnt fist "How dare you get punched and burn my beautiful fist!" He looked over at a Scowling Fionna. "AND you were going to hurt Fionna! That's far worse! How dare you!"
Flame Prince started walking towards Marshall "Stay OUT of this! You caused enough trouble today!" He made a fireball in his hand. "You wouldn't want to get burned, would you?"
Marshall laughed "I'm so hot your fire would melt if it hit me. So… bring it… Prince." He put both arms out and waved him to 'come on'
Flame Prince began to bombard Fireballs at Marshall. Smoke covered the air around Marshall.
"MARSHALL!" Fionna screamed as smoke surrounded him.
"That was ea…" Flame Prince stopped when the smoke cleared enough to show nothing. He looked around. "Did… he… melt?"
"Hey… hot head. Look up."
Flame Prince slowly looked up just to see Marshall floating above him, non-chalantly. Not a single burn on him.
"Oh… I'm sorry. Did you expect to hit me with… that? I could fake it, but I don't want to be like all the women you ''Pleased''." Marshall laughed as he floated next to Flame Prince. "You know I was remembering the time I punched you in the stomach, good times."
"You never punched me in the-"Flame Prince abruptly stopped. His voice left him as Marshall's fist slammed against his stomach.
"OH! I didn't? Well guess I had to make that a memory." Marshall laughed. "You can't beat me, Hot head. Not today, Not ever."
Flame Prince clenched his fist "Stop… Mocking… ME!" He released a scream which raised his fire enough to slam Marshall into the side of the treehouse, near Fionna.
"Marshall… stop. This isn't yo-"Fionna looked to see a fireball come at her. She jumped back, but not enough to stop from getting hit in the leg. She screamed and fell holding her leg.
Marshall watched as Fionna laid there in pain.
"Don't help him!" Flame Prince's rage had taken control of him. He did not mean to hurt Fionna.
Marshall's eyes began to darken and hair began to change. "Flame… Prince…" Marshall stood up.
"What is it?! You want to die?!" Flame Prince pointed at Marshall and laughed "I can give you what you want!"
Marshall began to walk slowly at Flame Prince. His eyes were pitch black and his hair began to turn white. "Flame Prince…"
The look in Marshall's eyes made Flame Prince back up. He began to throw fireballs at Marshall, but they kept getting smacked into the dirt. The gap began to close between them. Suddenly Marshall was in front of Flame Prince. His hand wrapped out Flame Prince's throat. The smell of burning flesh filled the air, and the sound of a choking Flame Prince could be heard by Fionna. She had watched the whole thing. Marshall was not himself anymore. He had white hair and he had pure black eyes. She had never seen him like this in the four years she had known him. She watched as Flame Prince got raised off the ground by his throat, and while he struggle for air. Finally she stepped in.
"Marshall! Stop! You'll kill him!" She ran to him.
"Fi… I have to. He can't hurt you if he's dead!" Marshall clenched tighter.
"Marshall, seeing you do this is hurting me!" She wrapped her arms around him.
This made Marshall drop Flame Prince, who then collected his air and decided it was time to leave before Marshall changed his mind. Marshall looked at Fionna, she had tears running down her face.
"Fi… I'm hurting you… I'm so sorry." His eyes began to turn back to brown and his air darkened back to black. He dropped to his knees. "I'm so sorry."
For the first time ever Fionna saw Marshall do something that she thought she would never see, he began to cry. She looked at him in awe. He had severe burns on his hands, but yet he cried because he had hurt her, emotionally. She lowered herself and pulled Marshall into a hug.
"Mar-" She got pushed off.
"No! I'm a danger to you. I have to… go… hom… n…" Marshall tried to stand and walk. He got a few feet before everything went black and he was on the ground. He was unconscious and Fionna did not know what happen. She slid on her knees to him and shook him.
"MARSHAL! WAKE UP!"
He gave no response. So she lifted him up and carried him back into the house and to her bed. Within seconds Cake walked in. She saw the whole thing and was worried about Fionna.
"Baby… are you alright?" She rubbed Fionna's back.
"Yea, but Marshall passed out…" She sat down next to him.
Marshall sat in pitch black. He looked around. No one was around, no one could help, he was alone.
He called out, but only his echo returned. He stood up and walked around. Within seconds he found a door. He pulled it open and walked through. He was in a familiar room, but he did not know where he had seen it from before. He walked to the bed and sat on it. His foot hit something under it. He reached down and pulled out a small lockbox, except it had no lock on it. When he opened it his eyes could not believe it. Pictures of his family. His mom, his dad, and him. He knew where he was now. He was in his room, his room before the bombs, before it all. He was home.
A knock came from the door, and it creaked open. There stood a white hair, black eyed, man.
"Hello, Marshall. It's me… your Demon."
