It was a stormy day in the Land of Ooo. The weather had been quite vicious lately, with heavy gusts of wind combined with the rain, which just resulted in being near impossible to get outside. At one Treefort, a small green square Gameboy device rested on its side, out of boredom from the main owners of the home being gone. It felt a lot lonelier without them. Though, the door opened to a familiar fourteen year old boy who entered, wearing a light blue shirt and dark blue pants and a white bear like hat. His entire body from head to toe, however, was soaking wet, and he had weird green stuff on his hands as well.
"Hey, BMO," Finn greeted. He was well known throughout the land as the last human being alive. He sighed before closing the door, tired to his core. He just went over and plopped down on the couch. "Are you okay, Finn? Where is Jake?" BMO questioned while climbing onto the couch beside him, wondering where his older brother Jake was exactly. "He couldn't take the rain anymore while we were out, so he went to stay at Lady Rainicorn's. And yeah, I'm fine. Just hard to fight monsters in this weather…" the human reassured while wiping his hands off. The green goo was the blood of a form of monster. The young boy just wanted to take it easy. "Do you want to play?" BMO offered, showing a controller with two buttons on it and a joystick. Finn just smiled, happily taking the offer to enjoy some gaming after the hard day.
Finn and BMO had spent the past hour playing a small adventure game. It was a basic 2D sidescroller, and it was one of their more favorite games of the bunch. He played it often with his brother, though at one point, Finn kept letting his character die. After countless deaths that even Finn lost count, BMO had to finish the level for the two of them. The little electronic device cut off the game and looked to its housemate, who was lost in thought. A pixilated expression of worry showed on the screen. "Are you okay?" BMO requested to know, snapping him out of his thoughtful trance. "Huh? Oh yeah. I was just trying to think of everything I gotta do tomorrow. Bubblegum needs my help with some of her inventions lately," Finn explained, sounding tired, just thinking about it before hearing a loud thunderbolt strike outside.
BMO had to think on this for a second, having noticed something lately when it came to Finn. "You've been with her a lot since you and Flame Princess broke up. Do you think she might be taking advantage of you?" the electronic suggested. Finn was quiet. He didn't want to consider it, but lately his brother had been trying to teach him not to blindly trust everyone after recent incidents on adventures where their trust put them in danger.
"Nah. Peebs is a good friend. Besides, I don't really have much else to do…" Finn admitted. The most he had done for the past few days was walk from one kingdom to another and back to the Candy Kingdom, all to fill some requests for a friend. He didn't even have an idea what he was helping with half the time. Even BMO's words seemed to strike a nerve though. "I need to just take a day to relax…" the human boy spoke, putting the controllers away, having gotten bored of playing games right now.
"I'm sorry," BMO apologized, thinking it had ruined the fun of the afternoon the two were having. Finn just patted BMO's head. "Nah, don't worry about it. Besides, the last time I ran around this much, Marceline found a wolf gnawing on my leg," he laughed, reminiscing about the past like it was a fun memory. There was a pause between the two. "If you'd like… I want to test out this new program I got…" BMO claimed, making him raise an eyebrow. "New program? Is it a new game?" he questioned. "No… I… I wanted to know emotions more. So I downloaded this new program to help me feel more. …Can you help me test it tomorrow?" BMO explained. This just confused Finn. He wondered why and how he could help test a program like that.
"Sure. It sounds like fun. I'm going to go to bed now. See ya tomorrow, little guy," Finn bid BMO goodnight, but when he approached the ladder, BMO felt something telling it to correct the human for some reason. He heard BMO's voice chime out. "Uh… could you start calling me… little girl instead?" she requested the first thing that came to mind. It felt more fitting to be referred to as a girl. Finn just stared for a second with a hand and foot on the ladder. An awkward silence swirled in the room. "Y-yeah. Sure, BMO. Sorry…" he apologized, just continuing up to his room to get cleaned up, wanting to get out of the still wet clothes.
BMO was lost in thought for a brief moment, shaking herself out of it. "W-wow… maybe that was an error with the program?" she wondered to herself. She reached over and picked up the controller, wanting to try and forget about it and continue playing single player, feeling embarrassed.
