So Are You To Me

A/N: Is my heart going to break the same way when Bones ends? Anyway I thought it was a decent ending, most of the shows I like haven´t been given that

Introducing Kyan Lucas Castle. My timeline is a bit mixed up but it has to be this way in order for the story to work. There will be more background on him as the story goes on, I already tried a story with him which didn't work but I thought it'd be interesting to see his dynamic with Beckett

I own nothing except for Kyan . Remember this is AU.

Part I

Kate was the first one to wake up . The house was quiet. Too quiet for her taste. Still, she turned around to eye Rick sleeping next to her. His breathing, even and calm.

Today was a good day. In fact, it is a great one, one that is 14 years in the making.

Today was Kyan's last day in junior high.

It is also a bittersweet one, specially for Castle she knows. It haunts him. The idea of him growing up. The idea of him not being that trouble maker little boy of him.

That boy Kate met when he was just 6 years old. Alexis's little brother.

Her little brother who's now a teenager, a young man, who struggles to make sense of the world like the rest would, and yet he makes sense of it his way and he certainly makes sense in their world. Specially for Kate.

She allowed her husband sleep a bit longer and slipped away from bed quietly. She stopped just a moment to pick up Lily who seemed to have woken up. Her baby girl was 3 now. And it was just crazy how much time has passed since the shooting. Almost four years to the day. "Come on sweetie. Let's see what your brother is up to"

Kyan was not a morning person, odd enough for a systematic little guy. Alexis had explained to her when she first met him. Her brother needed schedules or else they'd have a mess in their hands.

And oddly enough for Kate, she and Kyan had been like to peas in a pod. Not like Alexis who had seemed to resent her a bit or... Maybe not, but for Kate it was a chance to see herself as a mother.

"Good morning Kyan." Kate said softy. His soft blue eyes looking up at her.

"I made coffee." He said proudly. "Thought you needed cause you came home late. At 2:03 am to be exact."

"Did grandma help you?" Kate asked. He knows he can't be around things that burn, not without supervision. "Thank you, just what I need."

"Alexis." He said simply. Oh yes his sister, that was allowed too.

"Well thank you bud."

"Dad?"

"He's not awake yet" Kate said, placing Lily on her chair as Kyan moved up to the kitchen island, dragging his feet.

"I'm hungry." Kate has to smile because even in his way, He is her little boy. He and Castle are experts on getting their way around with her. Something that is starting to rub on Lily.

Lord help her. "I'm going to wake him."

"Kyan" She hurried to say and yet she was amused. So she didn't try to stop him.

"You always say, nobody eats unless everyone is here."

That everyone also included Martha and Alexis but somehow it only applied to her and Castle. She was sure Alexis and Martha had somehow managed to get away from Kyan's clockwise breakfast.

True to his word. Father and son came stumbling into the kitchen a moment later, earning a cute scream from Lily whom Rick quickly scooped up. "Breakfast huh?"

"He wanted your chocolate chip pancakes to start the day."

"Nothing better than chocolate early in the morning."

"Well maybe there's one thing that's better." Kate whispered huskily.

"There is?"

huh- huh" she leans to kiss him softly on the lips.

Ring.

What on earth? This early in the morning?

"Did my mother lost her keys again?" Castle moved to open the door.

"Rick!" Oh boy

"Meredith."

He knew she was coming. Truth be told he was a bit surprised she actually showed up. Meredith's relationship with Kyan wasn't the same as it was with Alexis. Truth be told, she struggled with the fact that her son was a special needs child.

"What are you..."

"Don't worry, I can't stay long, I have to check into my hotel." She said her hellos to Kate and Kyan who struggled to make eye contact with her. "But I would like to have dinner with you two, maybe tomorrow, I have something to discuss." Kate looked at Rick.

And just like that she was gone. Before either of them could react.

"Suspicious." Rick said as he proceed to make his famous chocolate chip pancakes.

"The spoon is mine, right dad?" Kyan said proudly.

"Manners buddy, manners." Rick smiled as he finished.

"Can I have the spoon, please?" He made such a Castle look, Beckett had to laugh.

"Yes you may"

And just like that they sat to breakfast, with Alexis and Martha joining them soon after. "Was that mom I heard?"

"Yes, said she had to run, check into her hotel." Castle told his daughter when she asked why she hadn't even said hello to her.

"What was it that she wanted?" Martha asked Rick and Beckett about Meredith's surprised show up. She hadn't even said hello to Alexis.

"Weird, right?" Kate pointed out.

"Very. I'm guessing she has some plan. Maybe she wants to move back into town." Castle said as he helped Lily pour some syrup on her pancakes.

"Well that wouldn't be so bad, at least she'd see her children more." Martha put in.

Was that it? After almost ten years or so of having not really being there?

"What's wrong babe?" Kate asked Castle as they got ready to go in their bedroom.

"Meredith."

"Right. I'm sure it's just like you said. Maybe she wants to move back and spend more time with the kids."

"Yes but why now? She hasn't been interested before."

"Mom?" Came Kyan's voice from the door. The kid was almost as tall as Rick and if Alexis took after Meredith, he was all Castle. More so wearing a suit which he'd be soon complaining about.

The mom thing had happened fairly quick for Kate and Kyan. They both needed each other more than they imagined.,

"Good job buddy, I like that look, it suits you." Rick said with a smile.

"How long do I have to wear it?" He quickly asked. Castle and Beckett shared a look.

"Just until the ceremony is over. I'm getting you a change of clothes, okay?" She said with a smile, much to her child's peace of mind.

Kyan and fancy clothes? Yeah that didn't work

"Here let me help you with the tie." Rick moved to help with the finishing touches.

In addition to being born with autism , he struggled with some motor skills, which were more prominent when he walked long distances or tried to tie his shoes. Or in this case, a tie.

"Let me see you." Kate smiled. "Very handsome."

"He has to be. With me as his dad, right buddy?"

"We're going to be late if we don't hurry." Kyan said in a matter of facty. Kate and Rick smiled.

"What do you say Kyan?" Castle said before the boy left the room.

"Thank you mom."

"Yes, thank you mom. Good, now go and make sure your grandma and Alexis are ready to go"

Showtime.

First Part! What did you think?
