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

Annabeth didn't believe in nurseries or nannies, for that matter. So, whenever her little ones needed to be look after and she was in some meeting, was Grandma Sally who looked after them. But, today wasn't one of those days. Today, she was having the house for herself and for Bianca, sort of speak, as the men of the house were all away and together.

Bianca was never like her siblings, though that could clearly change, Annabeth pondered, while watching her only daughter from her desk, in her office. She was sitting on the couch, reading one of the many books that was laying around the house about marine biology. Percy needs to be more organized... was her thought when she returned to her drawing. She could never imagine what would happen next.

Bianca read the book with fascination and more attention that any adult would. She was fascinated about how the corals and reefs were made and that, ignited an idea inside her head. Stubborn as both her parents, Bianca peaked through her book to see if her Mommy was looking at her direction. She wasn't. As silently as she could, she climbed down the couch and rushed to her room (shared with Charlie, but that was a temporal arrangement).

She quickly searched for a piece of paper and some crayons. Bianca knew she was good doing drawings and liked to be praised for them, so she decided to do her best effort. Carefully, she laid down on the carpeted floor, belly down and choose one color, coral, before starting to draw.

It's been a while since Annabeth looked up from her work. Percy always claimed that she absorbed herself on her projects and that, if she wasn't careful, she could go to extremes. Like that time that Percy came back from work and scolded her (a weird occurrence, if anyone asks) about not eating all day when she was pregnant of Luke.

When she finally looked up, the first thing she saw was the wall clock. 11:30am. Not the appropriate time for a snack, but the right time to prepare lunch for her and Bianca. She glanced to the couch and saw that Bianca was missing from that place. So was the book she was reading. Frowning, she got up from her chair and walked towards the twins' room, where she found Bianca surrounded by paper and crayons.

"Bi..." Annabeth sighed, a little releaved. She had never lost a kid before and wasn't starting now. Bianca looked up from the paper she was drawing and smiled at her Mommy "What are you doing?"

"I was reading about those coral reefs in that book that Daddy uses and then, I remember when he took us on vacations last summer..." Bianca began her explanation. Annabeth, while listening, started to clean a spot next to her daughter to sit down "I was thinking how cool would be to have a room that was made out of reef and then, I remember that Grandpa Poseidon told us about visiting... Do you think he'd be upset if I told him how I want my room?" she finished, fidgeting with her hands, a little worry about what her Mommy could say about it.

Annabeth, meanwhile, had picked some of the drawings that Bianca had tossed aside, unfinished. People always used to say it, but she understood it in that moment that Bianca was a combination of hers and Percy's best features. The details on the reef, along with the structural benefits made Annabeth amazed by her daughter's abilities.

"You know what, Bi?" she finally said, before looking at her still worry daughter "I think Granda Poseidon would love these"

The smile on her little girl was enough prize.

When Percy returned with the boys right before dinner, he found both girls sitting down on Annabeth's desk (well, more like Bianca was on Annabeth's knees), totally concentrated and discussing a few things between whispers. Percy smirked, before knocking softly on the door.

"Knock, knock, WiseGirl..." he called his wife, making her look up, a little startled.

"Percy! When did you arrived? What time is it?" she began asking, clearly confused at the time. Percy chuckled, before greeting the speeding bullet that his daughter became.

"Daddy, Daddy! You won't believe what Mommy and I were doing today!" she stated, totally excited. Obviously, whatever the girls were doing, had her all happy. And Percy wasn't gonna argue with whatever that was.

"Let me guess, OK?" he asked, while picking her up in his arms and carrying her to the kitchen "Oh, and before I forget!" he peaked his head inside Annabeth's office "I bought pizza, as the boys did a good job today..." Annabeth caught the double meaning and walked right behind her husband, who was listening to their daughter babble about her day, not waiting for her Daddy to guess.

"I designed my own room for Grandpa Poseidon's place!" she announced, all proud "Mommy helped me a little, but I did all the thinking!"

"So, you did? Very good! I'll see the drawing after dinner, OK?" he promised her, before putting her down on her chair.

"I also did drawings for Luke's and Charlie's!" Cue to her brothers to pay attention to whatever she was talking about.

"Ohh! You think you can have mine with hoops and stuff for dolphins?" Annabeth heard Charlie ask his twin, all excited. Apparently, Percy had made him swim with dolphins "And, and, what about the eels, Daddy? You think they want to work like light bulbs?"

"Sure, pay them with shells, they'll like that..." Luke rolled his eyes, sarcasm dripping from his words. But none of the twins realized about it.

"Mommy! We can add a transparent ceiling where the eels can swim freely and the can give us light!" Bianca's eyes opened at the possibilities, while Annabeth smiled at her in agreement.

Kids do have overactive imagination.
