I just want to say, I would love a review or two just so I know people are actually reading this. If I don't I'll probably stop. Anyway, here's the installment I wanted to post. Hope you like it.

Enjoy!

Kate knocked on the door to Castle's loft. He had called her earlier and told her to come over and she had almost told him, "No." But, after hearing him complain and whine, she conceded.

"Beckett!" Castle exclaimed opening the door. She eyed him suspiciously before walking in the room and giving the writer her coat. She was about to ask why he had her come over, when she heard two girls screaming her name.

"Hi!" Kate said happily as she and the girls hugged. She looked up at Rick who smiled.

"Grandma and Grandpa went out for their anniversary!" Lanie said breaking the hug, "So Rick is babysitting us!" Kate smiled at the girl before looking at Cassie.

"Why are you covered in flour?" The detective asked.

"We're making pizza with Alexis!" Cassie told her as her sister took hold of Kate's hand and said, "Come see!" The girls led Kate to the kitchen to see Alexis covered in flour.

"Have a fight with the pizza?" Castle asked his daughter as he came in the kitchen behind the girls. She rolled her eyes at him as he went to help her.

"Make one with us!" Lanie and Cassie said as they went to finish their food. Kate smiled and helped the six year olds into their aprons before making a pizza of her own.

Fifteen minutes later, the pizzas were in the oven and the group was cleaning the kitchen.

"Where's your brother?" Kate asked the girls as they washed their hands in the sink.

"He's playing in his playpen." Lanie responded flicking water at her sister. Cassie glared at her before flicking water back.

"Hey, you two." Kate lightly scolded trying to gain control of the possible water war that could ensue.

A few minutes later, Kate and Alexis were entertaining the girls with television when Rick came out of the study with Corbin. Kate smiled when she saw them. The boy's eyes lit up at the sight of Kate as he reached out for her. The writer set the boy down so he could walk over to the detective. Happily, the woman picked the child up set him on her lap. Rick sat down with the group, but was surprised when Alexis got up. A minute later the teen came in with a camera and snapped a picture of the adults sitting with the kids on the couch. Kate looked over at the girl, fully aware a picture had just been taken of her.

"I want a copy." Kate told Alexis. The teen smiled and said, "Sure!"

The ding of the oven a few minutes later sent Rick to the kitchen to get the pizzas out.

"That's mine!" Lanie said pointing to her pizza.

"Your pizza little lady." Castle said putting Lanie's pizza on a plate to take to the table. The girl giggled before taking the plate from the writer. Once everyone had their respective pizza including Corbin, the group sat at the table.

"Wait!" Cassie said before everyone ate. Everyone looked at the girl before she said, "We need to take Corby's shirt off so he doesn't get it dirty." Nodding, Castle said, "You're right. I'll take it off him right now." The man took the toddler's shirt off him before setting it with his diaper bag. Once he came back to the table, everyone started eating.

"Guess who came to our school yesterday?" Lanie asked excitedly as they were half way through their meal.

"Who?" Castle questioned.

"Detectives!" Lanie replied. The adults and teen exchanged glances before Kate asked, "Why were they there?"

"They were teaching us to be safe from strangers." Cassie said wanting her turn to speak.

"What kinds of things did they teach you?" Castle questioned. The girls thought for a moment before launching into their explanation.

Once dinner was over, Castle took everyone's plates. He was about to walk into the kitchen when he saw Corbin covered in pizza sauce. Chuckling, the man said, "Did you make a mess buddy?" Corbin smiled and said, "No." The group laughed a little at the baby's antics before Kate said, "I'll clean him up. Do you want to help?" She directed to the girls. They nodded and went off to help bathe their brother. The child happily played in the water with a couple toys while Kate and the girls cleaned up his face and washed his hair. They had just taken him out of the water when they heard Castle open the door.

"Looks like your grandparents are back." Kate said. The girls sighed wishing they could stay longer. Smiling, Kate said, "Go grab your brother's clothes." Cassie and Lanie ran out of the room and came back a few minutes later with the clothing and a diaper.

A few minutes later, the quartet came out of Castle's room with an energetic toddler who was walking over to Castle. The grandparents smiled as they watched the man interact with their grandson.

"Were you good for Mr. Castle and Detective Beckett?" The girls' grandpa asked them taking the diaper bag from Beckett.

"They were great and very helpful." Kate answered. Smiling, the girls looked at their grandparents and asked, "Can we stay a little longer?"

"It's getting late and you have school in the morning." Their grandmother said to them. Sighing, the girls' nodded.

"Go get your stuff." The grandfather told his granddaughters. The girls went to get their things as Mrs. Sanchez took her grandson from Rick's arms and said, "Thank- you for watching them."

"No problem. They're good. Besides, Kate and Alexis kept them entertained more than I did." Castle responded before saying, "Did you two have a nice time?"

"It was wonderful. Estebàn took me to the place we met." The woman said smiling.

"Where is that?" Castle questioned. Kate glared at her partner silently telling him he should stop butting into people's personal lives. He was about to say something when the girls came back.

"You're not leaving anything?" Castle questioned. The girls shook their heads.

"What do you tell them?" Mrs. Sanchez asked.

"Thank- you!" The girls said simultaneously. Kate and Rick smiled as they gave the girls hugs. Shutting his door, Castle sighed.

"That was exhausting." He told her.

"Getting old Castle?" She teased.

"Not that old." He teased back. Rolling her eyes, Kate said, "I should go." Castle nodded handing the detective her coat.

"Thanks." She said as he helped her into the garment.

"Night Kate." He told her. She smiled as she opened the door.

"Night Caslte." She said before closing the door behind her and walking down the hall.
