It had been four hours since they wrapped up the case, and she had finally finished the paper work. When she was leaving she grabbed fries and a shake, headed straight home, and went straight to bed. It had been a long day; it was only her and Esp solving the case. Ryan was home sick, and Castle was on a book tour. For the next couple of weeks, it was just her and Javi.

It had been four hours since the book tour wrapped up. Everything had finished earlier than expected, so now he was on his way home to surprise his wife. He was sitting in the back of the car when his phone pinged. It was text from Beckett. "I think I might be pregnant?" His eyes got wide, and just as he was about to respond, his phone died. He had no way of answering her until he got home.

Not sure if Beckett was asleep, he slipped his keys into the lock and tried to enter as quietly as possible.

What he didn't know, though, was that their Golden Retriever, Royal, had woken Kate up. "Royal, it's not play time." Royal jumped off the bed and rushed to the door, whimpering and pawing at it. Not sure why he was acting so strangely, Kate grabbed her gun and opened the door just a crack. To her surprise, she saw someone standing in the kitchen. She ran over to him, tackling him to the ground.

"Ow! Why did you do that?" He asked, his hands pinned above his head.

"Castle?" She said, sounding puzzled. Royal barked behind them, still keeping watch.

"Do you have any other husbands?" He widened his eyes, sarcasm in his voice.

"Sorry." She unpinned him, standing up and turning on the lights.

He rubbed his neck, sitting at the island. "Ow, that really hurt."

"Well, Castle, what did you expect?"

"A better welcome home than being tackled would have been nice!"

"Sorry, babe, Royal thought you were breaking in." She walked over to stand by him.

"Should you even be tackling anyone while you're pregnant?"

She widened her eyes. "How did you know I was pregnant?"

"You sent me a text earlier. Seriously, through a text?" He held up his phone which was now charging, displaying her message.

"Oh my God!" Beckett said, gasping and covering her mouth with her hands. "That text was for Lanie!"

"Lanie? Why Lanie? I thought you would tell me first!" He gave her a look.

"I was going to surprise you! Ugh!" She buried herself in his shoulder, and he wrapped his arms around her.

He kissed her temple, "We're going to have a baby!"
