A small one- shot based on what I think could happen if Alexis heard about how Javi and Ryan call Kate and Castle "Mom and Dad".

Disclaimer: I don't own Castle. Andrew Marlowe and ABC do.

Alexis made her way up from autopsy. She walked intot he bull pen to find her dad and Kate walking out. Not wanting to intrude, the girl stood out of eye sight.

"Nice to see Mom and Dad back together again." Javier Esposito told his partner. Ryan nodded before saying, "What do you think they talked about in there?" Javi shrugged.

"Who knows." He said, "It beats the fight they had earlier though." Ryan agreed before saying, "I wonder how often they fight like that."

"According to Lanie, a lot. If you ask me, they're secretly married and we don't know it." Esposito told the other man. The other detective laughed before someone caught his eye. Alexis stood in her hiding spot trying to fathom Kate and her dad being married.

"Hey Little Castle." Javier Esposito said looking toward where his friend was looking.

"Hey," she said brought out of her thoughts, "Have you seen my dad?" She asked not wanting them to know she had heard their conversation.

"They just left. Probably headed to Remmy's." Esposito responded. Alexis nodded.

"Did you need him to take you home?" Ryan asked.

"No, Dr. Parish said she'd drop me off." Alexis responded. She stood in the room not sure how she should leave. Deciding she wanted to know what the men were talking about she said, "What did you mean when you said Mom and Dad earlier?" The detectives looked at each other.

"You heard that?" Javi asked. Alexis nodded.

"It's just what we call them. Beckett keeps us in line and Castle helps her." Ryan explained.

"Okay." Alexis responded knowing there was more to what the men told her. Shifting a little she said, "I gotta go. Lanie's waiting for me." The detectives nodded.

"Alright, see you later." Ryan said as Javi called, "Bye Little Castle." Alexis entered the elevator not sure how she much she should intrude in her dad's life. There were too many things she had not fully understood about how her dad and Kate operated. Now that she was working with them, she was not sure she wanted to know.
