I do not own A.T
The vampire queen strummed her axe-bass while floating in the house. She was trying to think of a new song when her thoughts were interrupted by a knock on the door.
Marceline opened the door to find a handsome teenager in front of her. "Hey, Marceline!" shouted the teen in excitement.
"F-Finn…?" Marceline said in shock. The human boy looked different. She noticed his voice was deeper.
"That's my name! I came back from the Four-Year Tour of Adventure. It was awesome! Can you believe I'm already 18?" Finn said.
"You've…changed." Marceline exclaimed. Indeed the hero's appearance differed from when he was 14. He still had that goofy smile and blue eyes, but his hat was connected to his white T-shirt that had the picture of a sword on it striking through the word adventure so it worked as a hood.
He had black skinny jeans and blue Reeboks. His hair was still blonde but it was cut back to his head. There were some spiky strands and the end was combed to the back of his neck. He even grew to be at least two inches taller than Marceline.
"Yeah, Jake told me that since I was going through puberty I should change my appearance. But you haven't changed at all. Because you know, you're immortal." Finn said.
"How are you wearing skinny jeans?" Marceline asked. "I found them underground. Thanks to Marshall I learned what they were called and they even fit me!"
Marceline nodded, "So what do you wanna do?" Finn shrugged, "I don't know. What do you wanna do?" The vampire queen grinned deviously. "How about we celebrate with a party?"
Finn grinned. "Great! Let's have it at the fort! C'mon!" The human hero unbelievably began to float in the air.
Marceline was speechless. "I gained telekinesis during the tour. Cool, huh?" Finn asked. "Yeah…" Marceline said as she flew with the eighteen year old Finn to the tree fort.
