Chapter 2,"A Pity Reunion"Edit
Thirty minutes later, The ice is all gone and land is back to earth, It's raining and it's has stopped snowing. Finn approaches Jake's dead body, "Oh! Jake shouted while the camera stares at jake's hand, dripping blood. "Jake.." Finn said as jake slowly opens his eyes, " I'm sorry I wasn't here to save you." Finn then brings his head up. Finn and Jake start crying. "It's ok bro, I'll always be with you in your heart, your dreams, and your socks. Ow! I have only a few seconds left, I want you to know, I love you brother." "I love you too, brother." Finn respond back while he and jake are holding hand and let go. "Finn, Marcy's dad did this." "No." Finn says. "What time is it?" Jake asks giving a faint smile and raises his fist. "Adventure Time" Finn said giving jake a fist bump. "See ya in the other side..." Jake says "...uh...ohhh" Jake then sturns his head while his eye closes. "Jake.....JAKE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! " Finn says. He hugs up Jakes head to his chest and starts crying. After two minutes, Finn steadily puts Jake's head on the ground, stands up and says in a whisper. "Hunsen, I'm coming for you." The screen slowley turns black and the sounds of the rain stop.
Chapter 3: "A terrible thing"Edit
Finn marched to Marceline's house mad. He was also upset. He was both. When he marched into the cave, he heard a girlish scream. And it wasn't just any scream. It was Marceline's. Finn ran to the front door. He opened it. Marceline was kneeling down in a pool of blood. A pitchfork was right beside her. She was holding something. She held the thing's head to her chest and was crying her eyes out. After five min., Marceline turned to see Finn. Finn saw that Marceline was holding a young girl about his age. She was bleeding like crazy. Marceline turned back to the body. "Marsha..." she said. "I'm sorry I wasn't here to save you." Marceline steadily puts the girl down, stands up and whispers, "I'm coming for you." She turns to see Finn. "What?"
"What just happened?" Finn asked. "It was a typical day," Marceline explained. "I went needs to check on something in the cave, Marsha stayed outside. Once I entered the house, the sky suddenly turns from sunny and warm to cloudy and cold. Then stars snowing and the floor instantly turns into a large ice sheet above an ocean. Marsha must've seen a monster swimming to him under the ice, because she grabs a pitchfork and tries to stab the creature as it crashes against the ice. I heard her cry out "MARCELINE!" twice. I'll never forget it." Marceline sheads a tear. Finn frowns in guilt.
