Fionna was asleep when she felt the bed shake and a voice. She rolled over to see Marshall turning his head left and right violently. He was kicking the sheets and talking, but she could not make out exactly what he was saying. She leaned up and put her hand on him, she could feel the sweat coming off him. She did not even know he could sweat. Finally he said something she understood.
"Fionna…. Run…" He began to kick again. Fionna knew she needed to wake him up, so she began to shake him.
"Marshall. Marshall! Wake up, come on! Wake up!" She shook him harder. Finally his eyes opened and he sprang up. He gasped for air and stared straight ahead of him. Fionna sat behind him contemplating if she should say something. She slowly extended her hand and touched his back. His body jumped in shock and he turned to her. His eyes had something new in them, it looked like fear and anger. She decided to try to talk to him.
"Marshall. It's me. Fionna." She held up her hand at him. "Calm down. Whatever happen, was just a dream. Calm down. Please."
Marshall stared at her. "A… dream. Yeah… it was just a dream." He laid back down and exhaled. "Just… a… dream."
Fionna rubbed his hair. "You going to be okay? Need some… red or something?"
"Yeah… anything. Thank you, Fionna."
Fionna stood up and walked out the room. Marshall rubbed her forehead.
"What was that? That was no normal dream. That was too vivid." He rubbed his hand. "I felt… all of it."
He rose up and floated to the bathroom. As he passed the mirror he looked in it. Nothing was there. He ran some water and leaned down to splash it in his face. When he rose back up, there he stood in the mirror. Marshall backed against the wall.
"Just a dream! JUST! A DREAM!" Marshall fell onto the floor holding his head.
Fionna walked back into the room and saw Marshall was gone. She looked around and saw the bathroom door was open. Inside she saw Marshall holding his head and rocking on the floor.
"Just a dream. Just a dream. Just a dream." Was all he kept saying.
Fionna stared at him. She had no idea what to do. Then she remembered something Gumball had told her once, about Marshall.
-Flashback-
"So you're hanging out with Marshall Lee more now, I see." Gumball said as he flatten dough. "He has… some problems."
"Well we all do, Gumball. I mean you bake, Cake has a cat-nip addiction, and I have a might over-adventure." Fionna sat on the table and looked out the window. "Adventure…"
"No, Fionna, Marshall has real problems. I have been…. Around Marshall for a while and seen them."
"Whatchu talkin bout there Gumball?" Fionna crossed her arms and laughed.
"Marshall has been alive, or dead, for a long time. Unlike me though he has seen a lot of the world. He survived the mushroom war, Fionna. Marshall has what was once called PTSD. Post-Traumatic Stress Disorder." Fionna looked at him blankly. "It's a disorder where you can relive moments that were terrible and can go into a… let's say a kind of scared state. That and his serious Anxiety can lead to him going over the edge once in a while. I once saw him rocking in the bathroom saying 'Simone come back.' Over and over. It was terrifying. You don't really believe he's like that, until you see it."
"What did you do?" Fionna stared at Gumball with a scared look.
"Well I reassured him she will and that it will be okay. Then I just sat and talked to him, as if nothing had happen."
"Was it really that easy?" Fionna just stared at Gumball.
"No. Not for me. I was terrified and I hope you never experience it."
"Me too…"
-Flashback End-
Fionna walked over to Marshall and sat next to him.
"Just a dream. Just a dream." Marshall kept repeating with his eyes closed.
"Hey, Marshy, It was just a dream. It's okay now. It's over now." She ran her finger through his hair. "Just relax. Deep breathes."
Marshall stopped repeating himself and began to take deep breathes. Then he quit rocking and stayed still.
"It's okay. Come here." Fionna gently pulled Marshall to her lap. She rubbed her fingers through his hair. Marshall would never admit that he loved this. "You're awake now, and I'm here with you. It'll be okay."
Marshall began to breathe normally and suddenly it was all over. He sat up and wiped his face.
"That was a nasty one." He exhaled and sat against the wall. "Sorry about that. Normally I can control them, but then sometimes I get ones like that where I just… just…" He looked down and sighed.
"Hey… It's okay." She scooted closer to him. "I'm here to help. You're okay now and that's all that matters." She grabbed his hand and smiled.
Marshall stared into her eyes as she said this and felt, for once, that he was going to be okay.
"Fionna…" Marshall clenched her hand back. "You make me feel so… at peace with who, or what, I am. You stand by me through things like this, and yet you act like nothing bad happen. Like… it's not bothering."
"Cause It's not. Never will be. Because you're my best friend."
"I don't want to be just your best friend, Fionna." Marshall closed his eyes and sighed. "Have you ever seen the night sky without the moon and thought how empty it was?"
"Yes…"
"Before you came into my life, my heart was the moon-less night sky. Now… I couldn't imagine a night without you brightening my heart up, and for that I can only say one thing…" Marshall leaned forward and kissed her. Before she could kiss back, he pulled back. "I love you, Fionna… I truly… Love you."
Fionna sat in a daze. She stared at him for what felt like forever.
"I'm sorry… it's too soon… I mean... we're not even together. So… I'll just go…" He began to rise and walk out. When he reached the door a hand pulled him to turn around.
"Marshall… I love you too." Fionna pulled Marshall back into a kiss. The two held the embrace as long as they could, before Fionna had to break it for air.
"I… Don't know what to say…" Marshall held her close to him.
"Maybe you should say something like… 'oh Fionna, you're the best and I want you to be my girlfriend.' That would be something to say, right now." Fionna laughed.
Marshall cleared his throat. "Oh Fionna, you're the best and I want you to be my girlfriend."
"Well… Since you put it that way. I guess… I can try to be." She smiled and kissed him again.
"Well… better than nothing I guess." Marshall picked her up and swung her around. "Now… what do you want to do? Such a wide array of options…"
"Want to… go tell Cake?" Fionna smiled and held her thumbs up, waiting for a yes.
"I… don't WANT to, but…" Marshall stared at Fionna. "Fine… let's get my murder over with."
"YAY! She's going to be so happy. You know she likes you, right?" Fionna said running out the room.
"Wait! Really!?" Marshall yelled floating after her. He stopped at the ladder and smiled. "This is going to be a good day."

Here it is… they're together now. This is where it gets "fun."
Get ready people!
Vampiric King… Signing off.
