He was going to be smug about this for a long time. Kate should have stayed in the car, she knew that as soon as she had gotten out of it. The look on his face was enough. He did actually give nice hugs though, they were kind of comforting. She knew that he was a good dad, but in that moment she knew that he was one of the better ones. Despite all of that.. other stuff.
The moment he took a picture of them together, she gasped and reached out to either hit him or grab the camera. Probably both. "Hey! What the hell, Castle?!" A picture? Really?
"You couldn't have just asked or something? What are you going to do? Show it around to people? no one else is here for you to show it to." So ha! He didn't know that it was just her and now him and that was it. None of the other guys from the precinct where there.
