His Majesty, Supreme Lord of the Bathroom

By: TheExecutor25

Sunday, The Jackson-Blofis apartment

Percy Jackson had many titles, Hero of Olympus, son of Poseidon, and others. Although, the Supreme Lord of the Bathroom was not a common one.

It all started when Annabeth decided to visit once…

They had decided to study at Percy's place on Sunday afternoon. After having cookies from Sally Jackson, they had taken Percy's room to hang in.

"Hey 'Beth, I don't understand this equation can you—"

"Well…" She scooted over to him "…That's simple, you just…" and she wrote the whole process on a different piece of paper beside him so that he could use it as a reference.

"Ohhh" Was all responded with as he went to fill in the rest of the Algebraic expression.

This how most(Keyword: Most) of their afternoon went by, Percy being confused, Annabeth to the rescue.

That was the cycle until Percy decided to use the bathroom.

"Hey Wise Girl, I need to use the bathroom, I'll be quick," He said.

"Huh, oh right, sure thing" And he left for the toilet.

While he was there, Annabeth began thinking of random details that she noticed about him. First was the fact that his room was fairly neat, unlike his cabin at camp. Second, was that he seemed to have gotten slightly taller since they last met, though that may have been her. Lastly, their definition of quick was different.

She had just realized that he had been in the bathroom for what was nearly an hour. She became worried and decided to check on him.

"Seaweed Brain, you alright?" She called from the other side.

No response.

"Seaweed Brain?" She asked again, her concern growing.

Still no response.

"Percy, whatever you're doing there I don't care, I'm coming in!" So she pushed open the door but hadn't expected it to be open, she nearly fell and hit the floor if it wasn't for…water.

She was quite surprised when she fell into it, even more so when it filled the whole bathroom and didn't spill out.

"Hi Wise Girl" Came his voice when Annabeth stood back up, she saw him sitting on his toilet making it seem like a throne.

"Uh Percy, I dare to ask but…what did you do?" Surveying the room, from ceiling to floor was filled with water.

"Well…I decided to make this my domain" He said, giving her his classic lopsided grin.

"So you used your powers to make this I guess?" She inquired, one of her eyebrows raised, her arms crossed.

"Yup and besides, all the stuff is dry, you, me, the light and of that"

"Well at least you thought out about that now, are you going to come out of there?"

"Hm…I think I'll stay here actually"

"Er, what?" She was quite surprised when he said that, they still had a lot to finish in terms of school work.

"You can just bring me the papers and something I can use as a table…also a plate of cookies" He smiled bashfully at her and beckoned her out.

She shook her head and sighed, after that she walked out to get the items he had requested. She gathered his papers and textbooks, then a small lap table. After that, she ventured into the kitchen where she encountered Sally.

"Hey Annabeth, what do you need?" She asked as she continued stirring a bowl of soup bowl for dinner.

"Just a platter of cookies for Percy, he requested it for his 'domain'"

"Domain?" Sally asked, now confused at what she meant.

"Oh ya, he filed the bathroom with water—"

"He WHAT?!" Now she was shocked and confused.

"I think you should see it for yourself…also best to bring the cookies," Annabeth said and showed her to his bathroom. Upon entering, Percy was still on the toilet seat, drumming his fingers on his lap absentmindedly.

"Hello, loyal subjects! I see you have bought what I needed—" He greeted, lighting up as they entered the small room.

"PERSEUS JACKSON WHAT HAVE YOU DONE?!" His mother practically screamed at him whilst Annabeth began = quietly chuckling to herself.

"It's fine mom, nothing's broken anyway" He waved off her comment, eyeing the cookies that she had brought.

"I'll just have those now—" He said as he was about to reach for the cookies but his mother's arm contracted.

"You will not have these until you fix that and get out of there, no buts" Sally Jackson commanded, cutting him off.

"Fine, fine, give me a sec, I'll just clear this out," He said and concentrated the water to his will. Soon enough all the water had exited and the bathroom didn't even look like it was wet, just very clean.

"There, you happy?" He huffed as he turned off the light and stepped back out.

"Good, you can have these now, and better go back to studying young man!" His mother said, kissed his cheek, and left his room, leaving him and a chuckling Annabeth.

"So that was short-lived—" She said, still chuckling due to the event.

"Let's just go back to studying…" He mumbled, a cookie in his mouth.

They shared the plate of cookies between each other and resumed the study work they had to finish. They came out later that night just in time for dinner, which Annabeth joined in. He escorted her back to her apartment after they ate.

"See you tomorrow?" He asked as they stood outside her apartment door.

"Yeah, bye," She said and they exchanged a quick kiss.

.

That was only the first time, he had managed to do it not only his bathroom but in other locations that were: Enclosed with a source of water(Preferably in private).

Another significant instance was when Piper invited him and a few others for just a small get-together.

"Hey Piper, I'll just need the bathroom," He said.

"Huh, oh sure" She responded with.

And with that, he stayed in there for…Thirty minutes. It was only when Jason needed the bathroom did he realize that someone was still inside.

He knocked once, "Hey I need to use the bathroom", he knocked twice, "I need to Piss!" and the person finally made his presence known.

"Oh hey Jason, you can go," Percy said.

"Thanks, Perce—WHAT HAVE YOU DONE" He yelled attracting everyone's attention.

"Oh calm down Jason, nothing's broken or—"

"PERCY! WHY IS MY BATHROOM FILED WITH WATER!?" Piper shrieked as she saw what the son of Poseidon had converted her bathroom into.

"It's fine I can just remove it, hold on—" Percy said but was cut off by Leo

"HOW'D YOU DO THAT?" He frantically asked as he looked around.

"Oh, yeah and you can't get wet either—" He was cut off once again.

"That's so cool!" Leo said as if he were a child and entered.

"I can still use my powers here and I'm not yet wet!" He said as he demonstrated by setting his hands aflame.

Everyone excluding Annabeth and Percy stared in disbelief as Leo managed to heat himself further.

"Hey Seaweed Brain you want to—" Annabeth whispered into Percy's ear.

"Already on it…" He told her, "Hey Leo could you get out of there now?" He asked.

"Sure thing" And when he just about exited the bathroom, a gush of water drenched him completely, soaking him from head to toe.

"Percy!" He yelled as the demigod in question began to laugh, followed by everyone else.

"Relax Leo, you can just warm yourself because fire powers and Percy, the water," Said Piper, as she handed Leo a towel.

"Fine I guess," Percy said and slowly the water began receding into exit points.

"There, are ya happy?"

"Yup, now let's go have lunch" Piper answered and so they did, with Leo standing since he was still damp from getting doused.

Percy would go on to fill up more restrooms and bathrooms in whosever apartment he would happen to be in. This would earn him distrust from some of his friends so they made sure he stayed in there for no less than five minutes.

But he still would be the Supreme Lord of the Bathroom.
