Percy and Annabeth are 38, turning 39, each. Luke is 15. Bianca and Charlie are 5 each.

"Daddy, what do you do?" Percy looked up from his meal and looked at his youngest son, Charlie, who was playing with his food, instead of eating it, like his twin sister Bianca. He shared a look with Annabeth, who shrugged her shoulders at him.

"What do you mean, Charlie? I'm eating my meal..." he said to him, not understanding his son's question.

"Not now, Daddy... When you leave all day, Mommy said you go to work, but what do you do?" Charlie specified, trying to explain himself. He smiled at his Mom, who smiled at him because of the correct formation of the sentence.

"Oh, that! Well, Charlie, you're in luck, cause I can take you with me tomorrow... You wanna come?" Percy offered his son, who smiled and nodded, happy.

"Really?" Percy nodded, smirking, before looking at his daughter, who wasn't interested into the topic. In that moment, the door opened with a loudly slam, making the whole family to meet the eldest Jackson children, Luke.

"Lucas Ethan Jackson, explain in this instant why are you arriving at this hour?!" Charlie realized that it was the moment to focus on his meal. Annabeth Jackson was not a happy Mom at that moment.

"I'm finally here, Mom..." Luke explained, trying to avoid the fury of his mother. But she wasn't taking that answer.

"You won't give me attitude, young man" she raised an eyebrow. Charlie saw his Dad giving him a little smirk "You've been doing this for a week and I won't tolerate it. Right now, you're grounded from your convention tomorrow-"

"What?! Mom, you can't!" Luke complained, upset.

"-and you'll go with your father and Charlie tomorrow. And, don't you dare to argue with me!" she continued when she saw him opening his mouth.

"Luke, please, wash your hands and sit to have dinner" Percy ordered, in a gentler tone. Inside, Charlie was in deep thought.

Tomorrow was gonna be a great day!

"So, here's where you work, Daddy?" Charlie asked Percy, while walking through the doors of the newest and rebuilt New York Aquarium. Luke was walking a few steps behind, huffing and dragging his feet.

"Yep, I work here..." Percy said, proudly, holding Charlie's hand, before looking back "Luke, hurry up or you'll end up cleaning up the croc's enclosure!" he warned him. Apparently, it worked, because Luke speeded up and caught them before walking inside the aquarium "Hello, Greg... How's the wife?" Percy wondered to the guard, showing him his work card.

"Better, Dr. Jackson. Thanks for asking... Are these your kids?" Charlie waved at the guard, while he was talking to his Dad. Percy smirked and ruffled Charlie's hair.

"These are Charlie and Luke... They'll be with me today..." he explained, letting the kids walk in before him. Charlie was greeted with a vision full of tanks and water and several animals swimming around inside those tanks. Percy had to drag Charlie from his stop on the hallway towards his office, because his eyes were soon going to pop out his face.

"This place looks awesome, Daddy!" Charlie was quick into voicing his opinion of the place, while Percy put on a white lab coat. Both, father and son faced each other with a smile before turning to Luke, who was bored out of his mind.

"Yeah, super awesome..." he added, sarcastically. Percy sighed and was about to sit down when someone knocked on the door.

"Dr. Jackson, thank God you arrived early..." Charlie assumed that the man that walked through his Dad's office was some colleague or something "The dolphins had been acting weird since last night and we have a suddenly shy shark, not to mention that the eels seemed to make a boycott and electrified the entire pool..." It was obvious the poor man needed help to deal with all these problems "Oh, sorry, I didn't see you had company..."

"It's OK" Percy stopped the man, who gestured to leave "These are Charlie and Luke, my sons. Charlie, Luke, meet Dr. Silverman..." Again, Charlie waved, while Luke nodded in acknowledgement "We'll start with the eels right away" Dr. Silverman relaxed and left the office "Alright, kids! Time for our first task!"

"I thought we were going to stay in the office all day!" Luke protested. Percy looked at him, as if he was crazy.

"One, you're lucky to come on a busy day. Two... You think I'd leave you alone after the stunt you pulled last night?" Charlie knew his Dad was upset with Luke, because it wasn't common that he sounds this angry. Luke knew it too, which is why he kept quiet "You'll help me and, if you do a good job, I'll put out a good word with your mother, alright?" Luke nodded, resigned. The three Jacksons left the office towards the eels' tank, that was releasing lightnings "Now, Charlie, Luke... I want you to go to the front and talk to the eels, anything..."

"Daddy, what are you going to do?" Charlie looked at his father as if he was some kind of hero.

"I'm gonna try to slip into the water unnoticed by the people here-"

"They can hurt you!" Charlie cried, worry about what Percy was gonna do. Percy kneeled in front of him and Charlie hugged him right. Luke walked to his brother and wrapped an arm around him, slowly pulling him away.

"C'mon, we have to make sure they don't hurt him, OK?" Charlie wiped his face and nodded, unsure, but Percy gave him a smirk.

"Can you help me, Charlie? Keeping the eels away? I promise that we can swim with dolphins later..." Percy tempted him, earning a smile.

"OK!" he agreed, grabbing Luke's hand and walking towards the other side of the tank. Once there, the kids started to get the attention of the eels "Excuse me? Could you tell me why are you electrocuting the water?" he questioned the eels, serious "My Daddy wants in"

"Itssss our nature, son of the sea..." an eel started, focusing on the pair "We ssspark the water warm..."

"That's it? You wanted warm water?" Luke repeated, not believing his ears "Next time, just ask..."

"Daddy, Daddy! They want warmer water!" Charlie shouted through the aquarium, making Luke chuckle.

Today is going to end up being a great day...
