The third time Rick entered the 12th Precinct was after Beckett arrested him. She had lost her patience it seemed, and this visit to the precinct wasn't quite as fun as he'd expected. She ignored him the whole way, and sat him in a holding cell while his paperwork was processed. She'd continued to ignore him pointedly up until he left.
"So... no hard feelings?" Rick said to her as his daughter Alexis glared at him.
"Don't ever do that again," Beckett replied.
"We'll see," Rick answered.
"Come on, dad. Let's just go," Alexis said, grabbing her dad's hand and pulling. "Sorry, Detective," she said to Beckett. "He's a child. Don't mind him."
Rick turned to glare at Alexis, who stared at him plainly.
Beckett had cracked a slight smile at Alexis' description of Rick, and now she turned back to Rick. "I think, Mr Castle, you could learn some things from your daughter."
Rick looked down at Alexis, and then back at Beckett. "I'm sure I could, Detective. Well, as always, this was a pleasure."
"If you say so," Beckett replied, rolling her eyes. She turned her back on him and left. Rick watched her go with a little smile on his face.
