Story Note: This is a canon-divergence AU story. Neither Harry OR Percy will be OP, and neither of them will be ‘hybrids’ or ‘Mary Sues’ or anything similar. THEY WILL NOT BE INVOLVED WITH EACH OTHER’S STORY (I had to add that in after a guest gave me a lengthy review about what I could do next). Dumbledore has his canon, slightly manipulative but well-meaning personality, Sally is the best and Poseidon is slightly more involved in Percy’s life later on and Harry is way more smarter than in canon, because why not?

Chapter 3

Harry woke up first thing in the morning, more excited than he had ever felt in his entire life. It was the 24th of July. Which, of course, meant that it was the day that his Hogwarts letter would arrive. Harry knew all about it, of course, thanks to his Aunt Sally telling him everything she knew, down to the little details of his mom’s excited expression when told Aunt Sally about receiving her letter.

“Morning, Harry!” Percy said brightly with a huge grin when he saw Harry in the kitchen. “Mom told you to set the dishes– She gave me permission to make blue pancakes!”

“Well,” Harry quipped, “I hope you’re careful with the butter— we don’t want a repeat of the last time you made pancakes, do we?”

Harry remembered the last time well— Percy tried to make pancakes, and accidentally dropped a whole stick of butter into the fire. In less than a minute, it bursted into flames, and the stove was effectively broken. The blutter exploded everywhere, and it was only thanks to Harry that an invisible bauble of air formed around them and solidified, causing the butter to simply slide down.

Percy pouted, “Mom brought a non-stick pan. Didn’t let me use butter at all!”

Harry laughed. Butter was, in Percy’s opinion, the most vital ingredient to making a pancake taste good— after the endless amount of sugar that he’d put in, of course. “C’mon. I’ll help you with your pancakes.”

Percy shook his head. “Nuh uh. Mom told you to set the table. And I wanna make the pancakes by myself.”

Harry rolled his eyes, but took out the plain white plastic plates, and placed it on the table. He pulled out the forks and the knives, discarding it all inside a ceramic mug. “Fine. But if you’re burning it, it’s all your fault.”

Percy gave a pause at that, but he had already poured the batter in, the pan sizzling hot and making a slight fizzing sound the moment the batter came into contact with the pan. “Yeah, but isn’t it also your fault for not checking on me, right?”

Harry was tempted to strangle Percy. As much as he loved his little cousin, he was more than frustrated at times with him. His ADHD acted out in the most inopportunate times, sometimes in the middle of cooking, others when getting to bed, and the worse and most frustrating for Percy, in class. It wasn’t just that however, his cousin was particularly snippy and snarky, which of course, got on Harry’s nerves at times.

“Shut up, you buffoon,” Harry muttered. He went over to take out another pan, placing it next to Percy’s pan and turning up the heat. “By the way, where’s Aunt Sally?”

“Mom went to the grocery store,” Percy said with an unmistakable excitement to his voice. “She said she’s going to buy the ingredients for… well, you know… your cake.”

Ahh… yes. The cake. For his acceptance to Hogwarts. Which, now that he thought about it, should be arriving soon enough. He hoped Aunt Sally would be back before it arrived, so they could open it, and celebrate it together.

Suddenly, the doorbell rang, and Harry quickly killed the fire, disappointed he wasn’t even able to pour the batter. “I’ll get it,” he said, making way for the door. As expected, it was Aunt Sally, with two large grocery bags in her arms and a large smile on her face.

“Harry!” Aunt Sally exclaimed the moment she saw him. She pulled him into a tight hug, which caused the rather heavy grocery bags to hit his back. “Good to see you up and awake! Did you get the letter yet?”

Harry shook his head. “Not yet. It’s fine anyways, since I was hoping we’d get it together.”

Aunt Sally ruffled his head. “Well we better go in before Percy makes a mess out of the pancakes.”
