A/N: This is my first story and a one-shot. Sorry if it is lacking in any way, but I was bored and I wanted to give writing a shot. :D
Disclaimer: I do not own any of the Percy Jackson characters and this is all just for fun.
Scenario: This takes place about 15 to 25 years in the future and the setting is in a hospital. Percy and Annabeth are married with their first child on the way.
"It's been nine months hasn't it?" Percy asked. Annabeth just rubbed her bloated stomach and rolled her eyes at him, "Yeah, nine months filled with mood swings and intense cravings for fatty foods, oh the joy!" Percy just laughed, "I'm sorry, I'm not a girl, so I wouldn't know." She glared at him, but gave Percy a playful punch on the shoulder nonetheless. "Don't worry, daddy will take care of you," he said while rapidly moving his eyebrows up and down. Annabeth just bursted out laughing, "Daddy will, will he? Well let's see how our baby will handle daddy."
She gave her belly a light tap, "Do you think he can take car-" Suddenly, she cringed in pain and the first thing she saw when she opened her eyes was Percy's concerned look. Annabeth patted his cheek, "Don't you think it's time to call in the doctor?" That jerked him out of his paralysis, but it seemed that the doctor had already arrived. "Mr. Jackson, could you please step outside for a moment? It is a pretty grueling process."
The doctor was about 30 and somehow managed to get a uniform that allowed his muscles to bulge through. Percy disliked him immediately. He stared at his wife and asked, "Can we get a female doctor in here?" She just laughed and made shooing motions with her hands. Percy just sighed, but exited the room reluctantly. Just as he exited, he saw Dr. Muscles flip him off and lock the door while he was outside. "Why that little..." he thought to himself, but took a seat next to the door.
It seemed like hours before the door finally opened again, but when it did, Percy could clearly hear the sounds of a crying baby from inside the room. It was wrapped in a white towel and looked as fragile as a feather. The doctor gave him a thumbs up. Percy responded with a different finger. As the doctor left, Percy looked at his baby one more time and at that moment it opened its eyes, but something was wrong. The baby didn't have two eyes, it only had one.
Percy stared at Annabeth. She avoided his gaze and said, "Percy... I can explain." He was bewildered beyond belief, but calmly replied with, "So this isn't my baby huh?" Annabeth shook her head, "You know Tyson has a way with voices, don't you honey? When he talked like Stephen Hawking I just couldn't resist..." "WHAT THE FUUU!" Percy yelled out as he ran out of the room and through the hospital hallways. It was just as he was reaching the exit when he bumped into Tyson. "Congratulations brother!" he said, but Percy just yelled into his face, "It's yours!" He shoved Tyson out of the way and started running toward his car to travel as far away from the hospital as he could.
Tyson sullenly made his way to Annabeth's room and gave her a sad frown. Then, after a slight pause, they both started to grin and laugh hysterically. "Do you think we should tell Percy that we used the Mist to make the baby look like a Cyclops?" Annabeth managed to get out while gasping from lack of air. "Brother is so easy to fool!" Tyson croaked while laughing on the floor. After a while, everything went back into silence. It was Annabeth who broke it, "You know, we have to be more careful or this might actually happen one day." She glanced at Tyson to see if he was listening and he slowly picked himself off of the ground. "I know baby," he said in a Stephen Hawking voice.
