So, like I said this is based on the sneak peek where Martha and Castle are talking about how she saw Kate hiding in the closet.
I started this in geography and finished it while I was eating tea. I hope you like it :)
As he walked out of the lift and onto the homicide floor Castle thought about his earlier conversation with his mother. He couldn't believe she had seen Kate in his closet, he thought she'd been out of sight, and when his mother hadn't said anything at the time; that they'd gotten away with it.
He looked around and saw that Kate was sat talking to Ryan and Esposito. He was glad that the two seemed to have made up. Their partnership still wasn't completely healed but at least Esposito was talking to Ryan again, without being sarcastic or dismissive.
Kate must have heard the lift, or maybe she just knew he was there, because she looked up at him and gave him a quick smile before turning back to whatever she and the other two detectives were doing.
He walked over and sat in his chair. Kate looked at him and he passed her the second cup of coffee he was holding, their fingers brushing as he did so. Esposito looked at him and asked, "Weren't you going to spend the day with Alexis now that she's back from Europe?"
Castle nodded and shrugged, "We spent the morning together but she wanted to spend the afternoon with her friends before they all went their separate ways." Esposito nodded but didn't look convinced.
"So why are you here Castle? We don't have a case, just paper work," Kate said, before taking a gulp of coffee.
Castle shrugged again and tried to catch her eye. "I'm avoiding Gina, plus I needed to talk to you about something."
Ryan and Esposito both quirked their eyebrows while Kate looked hard at Castle. "About what?" she questioned.
"I need some help with something for Alexis."
Kate nodded, "Sure, what is it?"
He shook his head, "It's kind of delicate."
She looked him in the eye for a moment then looked around the bull pen. Once she saw that Gates was in her office and on her phone she looked at Ryan and Esposito, who were both watching her and Castle with interest. "I'll be in the observation room if I'm needed," she said as she stood.
The two nodded then watched as Kate led Castle towards the observation room. Once they were out of ear shot Esposito asked, "What do you think that was about?"
Ryan shrugged and turned his attention back to his paper work. "We'll properly never know, you know how secretive those two can be."
Esposito grunted and looked at the now shut door to the observation room for a few more moments before he too turned back to his paperwork.
Kate shut the door and turned on Castle. "What's up with Alexis?"
"My mother knows about us," he blurted out, "She saw you in the closet."
Kate just stood blinking for a couple of seconds before saying, "Well that was unexpected."
They stood in silence for a moment before Castle said, "Are you ok with that?"
Kate nodded, "Of course I am. I know we said we wanted to keep it to ourselves for the time being but people were going to find out eventually weren't they."
She shrugged and Castle pulled her into a hug. "She thinks I should tell Alexis."
Kate nodded against his chest then pulled back and stepped out of reach, "I'm at work Castle, you know the rules." When Castle nodded she said, "Yeah we should tell Alexis, she's your daughter and should be one of the first people to find out. We can tell her tonight if you want."
Castle beamed at her. He loved this woman, he really really did.
