The monsters kept pounding on the metal. The thunderous smashes don't stop. Marceline in the corner screeches inhuman encouragements at her companions outside. Fiona searches the room quickly, running about frantically.
"Welp, we're doomed." Jake says, sitting on a desk, resting his head on his fist glumly. Fiona shoves a bookshelf out of the way, it tumbles to the ground, crashing loudly. She smiles in relief at what she finds. On the wall, a few feet from the ceiling, is an air vent, just barley big enough to squeeze through.
Finn pulls a desk over to her, helping her set it on the fallen bookshelf. Fiona stands on the desk, while Finn holds it steady for her. She expects the air vent slightly before she turns to her friend, "Cake, give me a bobby pin."
The other girl steps forward, threading the hair utensil out of her dirty blonde curls, and handing it to Fiona. The tomboy is quick at work, unscrewing the nails with the pin. Once the metal plate is free, she hops off the desk and sets the plate down.
"Finny," she points to her brother, "you first. Keep an eye out for any baddies. Then Bubba. Then Jake. Cake and I will go last."
Gumball glances over at the zombie in the corner, which is suddenly silent and watching the group with suspicious eyes. "What about Marcy?"
Fiona's eyes flick from him to her. "She's already dead. It'll be fine." She helps her brother up, as she does, she whispers at him, "Keep Gummy alive. No matter what cost. Understand?"
He simply nods and climbs into the air vent. Fiona then helps Bubba and Jake into the vent. Slowly she turns to face Cake. Her friend keeps glancing at the zombie in the corner.
"She's too quiet. She knows something."
"It's dead. It doesn't know anything, Cake."
"You underestimate them. They're brainless idiots, but they can get what they want." Cake turns back to her friend, only to find the tomboy glaring at her. "What?"
Fiona takes a step forward, twirling her knife in her hands slowly. The zombies pound relentlessly. Cake thinks she hears something crack. Marceline snaps out of her observing trance and starts to thrash about wildly.
The younger girls starts to shake in fear, not sure which she hates more, the zombie threatening to escape, or the friend suddenly looking as vicious as the undead.
"Cake." Fiona clicks her tounge, her eyes slowly looking down to meet her friend's, "You have ten seconds to figure out why I'm about to do what I gonna to do."
"What?" The cat-lover stares in horror, her eyes finding the sharp blade in Fi's hand. "You're going to kill me? Why?"
"Ten." Fiona says simply.
"I- I don't understand. Why- why would you-"
"Nine."
"Are you mad at me?"
"Eight."
"You're mad at me. I can get that. What'd I do? I'll stop. I'll apologize. I'm sorry!" She was blabbering now. No closer to the answer than before.
Fiona swings the blade at her friend, just barely scraping off a hair on top of her head. "Seven. C'mon, Cake. Where's your weapons?"
"They- they all broke."
"Caught defenseless, how pathetic. I thought you'd put up more of a fight." Fiona jabs her knife forward, again just missing the other. She's teasing the other. They both know it. "Six."
"Y-you're joking right? You don't have my name. You couldn't." Cake says, lowering her hands, chuckling nervously, "You got me. Haha, that was funny. Now let's catch up with the others."
"Five."
"Stop it. That's not funny anymore. Let's just go." She says angrily, her hands balling in fists.
"Four. You have something I want. And I have something you won't like." Fiona's hand slips in her pocket and pulls out a small piece slightly crumpled of paper.
Her eyes widen in horror as she stares at the paper. Written on it, in messy writing is a word written on it.
Cake
Fiona drops the paper by their feet, "Three."
"You want my paper?" Cake asks in sudden realization, "Why? I don't have Finn or anything. It's okay. I won't hurt you or your brother."
"I know. You won't be able to harm either of us. You don't have a weapon. Two, by the way." Fiona smiles sadly, "I really don't want to do this. But I need the name you have. I'm sorry."
Cake was crying now, tears rolling down her face. Suddenly there were no zombies outside. There wasn't a monster in the corner of the room. It was just her and Fiona. "Fi, please, please don't do this. Please let me go! We can work this out. We can- we can wait til this is all over."
"It won't be over until I do this. Cake, don't you see?" Her voice grows to a whine. "I have to. I'm sorry."
Cake closes her eyes, sobbing quietly, "O-okay." Her voice wobbles as her body tenses, waiting for the pain.
Fiona can't see her friend anymore, her vision is too blurred by her tears. She quickly forces her knife into her friend's heart. She feels the blade rip through her muscles, tearing them apart in a mess of blood. The red liquid spills down her wound, splattering on the floor. Fiona yanks the dagger out of Cake, backing up slightly.
Cake cries out in agony, her knees shaking, she falls to the floor. Her hand clutches her chest, only causing her wound to rip more. She slumps even more, now laying on the floor completely, gasping for air in short breaths.
Her eyes slowly trail up to the paper resting just left of her head. Laying on the floor, her paper. Slowly letters begin to form on the crumpled, bloody mess. The last thing she sees is the paper. Her paper. Her name. Her vision fades, and finally Cake's heart stops.
Cake
Deceased
Fiona watches the entire ordeal, choking back sobs as her best friend dies before her. She quickly finds her new paper in Cake's pocket. She looks back at the cat-loving girl below her. Slowly, she presses a kiss against her friend's forehead.
The tomboy jumps on top of the desk. Marceline screeches, catching Fiona's attention. The two stare at each other for a moment, unmoving. Both only see a monster before them. Fiona growls at the zombie, "Don't you judge me! You're dead! You- you! Shut up!"
The girl then climbs through the air vent. Searching to find her friends. The only sound was the echoing of her hands and knees as she crawls and the sound of her own heart breaking.
