Warning! I do not own Adventure Time or any of its characters. Before we begin I would like to thank Teller14-djb for his review, for those of you who haven't yet checked out his story Into the Wormhole, you won't regret it. Now without further delay, on with the show!

"Hello?" Finn said as he stepped into the cell. The stone walls were covered with a thick layer of frost that someone had scratched various notes and drawings in. A boy who looked to be only a few years older Finn was laying on the bed absent- mindedly strumming a guitar that seemed to be made completely of frost. His skin was as white as snow and his pale blue eyes gleamed with defiance and madness. His hair was a dull grey that seemed out off place with his white cloak.

"Who are you?" The boy said staring at Finn with a look of confusion.

"My name is Finn," Finn said pointing his sword at the boy. "Now who are you, and what did you do to get locked up?"

"Who am I?!" The prisoner said looking down at his guitar. He stared at his reflection for a few moments before asking softly. "Who am I?"

"Hey Finn, did you find out who the prisoner is yet?" Jake said as he walked into the cell leaving the door open a crack.

"No, I don't even think he knows." Finn said astonished.

"It looks like he has poo brain man." Jake said looking at the boy still staring at his reflection. "Come on; let's go beat up Ice King or something."

Suddenly the prisoner threw his guitar at Jake's head. Jake ducked out-of-the-way in time and the guitar shattered against the wall.

"What was that for?" Jake said as the prisoner shot to his feet. His eyes were now a blood-red color.

"I shall encase this world in an endless winter, and nothing shall stand in my way! Kneel before the Prince of Frost!" the Frost Prince said in a voice laced with insanity.

"You'll have to get past me first!" Finn said as he charged at the Frost Prince with his grass sword. The Frost Prince used his powers to form two short swords made completely of frost. Finn swung his sword at the Frost Prince's head but he blocked the blow by catching Finn's sword with his blades.

"What the Glob!" Finn exclaimed as frost began forming on his grass sword.

"My powers far exceed your swordsmanship, surrender now and perhaps I'll spare your lives!" Frost Prince said as he backed Finn against the wall.

"A little help here Jake!" Finn said as he pulled his sword free.

Jake swung a giant fist at the Frost Prince but he jumped to the side at the last-minute. Frost Prince's eyes then began to glow white as he shot bolts of frost out of is swords and encased Jake in a ice.

"Jake!" Finn shouted looking at his best friend. The Frost Prince took advantage of this distraction and knocked Finn to the ground.

"Prepare to meet your fate, hero!" Frost Prince said as his eyes started glowing again. Suddenly the cell door burst open.

"Stop, Roy!" Princess Bubblegum shouted from the doorway.

"Bonnie?" Frost Prince/ Roy said as his eyes began to shift back to blue. However the change lasted only a few seconds before they shifted back to red. With a roar Frost Prince ran for the door and threw Princess Bubblegum aside. By the time PB got back on her feet Frost Prince had already escaped. Princess Bubblegum then turned back to Finn who was in the process of freeing Jake.

"I told you not to enter the dungeon, Finn!" Princess Bubblegum said.

"How did you know we were down here?" Finn asked curious about PB's sudden appearance.

"I had a motion sensor installed to alert me if the prisoner ever tried to escape." Princess Bubblegum answered showing Finn a hand-held device.

"So who was that guy and why did you call him Roy?" Finn asked

"His name is Roy Albert Bubblegum." Princess Bubblegum said unable to look Finn in the eye. "He's my brother."

Who is Roy Albert Bubblegum? Why does he now call himself Frost Prince? Why are his powers similar to Ice King's? When will I stop asking questions? Tune in next week for the answers.
