Castle has been waiting for a right time to tell Kate about this situation. Well, he knows that she's not gonna like this, but he has to try anyway.

"Honey, this breakfast was so good." Castle starts the conversation. "I'm sorry I didn't help you cooking, but I think you managed it pretty well."

"What's going on?" Kate asks him curiously.

"Huh?" Wow. That was fast, he thought. "What?"

"Tell me what is going on with you! You've been acting really weird since yesterday."

"Nothing."

"You do realize that I'm a detective, right?"

"Shoot. I can never ever lie to you, can't I?

"No, Mr. Castle. You, can not. So, what's up?"

"You're not gonna like this."

"Baby, you haven't even tell me what this is about."

"Right. Promise me you won't upset."

"Okay."

"So, um… you know, yesterday I had a meeting with my publisher. And there was Paula too, of course she was there. And she came up with this idea, that you may wanna come to the book signing par-."

"Castle, I always attend the party." Kate interrupts.

"Honey, Let me finish! She wanted you on the stage with me, answering questions from the press."

"Huh? that's new. Okay."

"WHAT? You're not mad? You don't even want to argue about this? " He really is surprised.

"Why would I be upset?"

"Huh? You really have changed since you're pregnant. I remember I asked you the same question couple years ago and you said, you didn't wanna come."

"No, babe, you didn't ask me the same question. You did ask me to be a Nikki Heat, and I couldn't do it. Actually I could, but you know, I think you know Nikki Heat better than I do. With your amazing mind and everything"

"Did you just say that I am amazing? For the love of God, I love you even more every single day. And have I told you, you look incredibly incredibly sexy this morning?"

"I am huge." She pouts

"Kate, honey, you look hot. I mean it. Seriously. Look at you! I am the luckiest guy on this planet. But for the record, you really okay with this? If you don't want to, just say it."

"Castle, I want to do it. Besides, I am off of duty from the precinct. It's only been 4 days, and I already am bored, because you've been out lately, doing meeting and doing book promos. And I've missed you."

"Honey… " Castle feels so bad for leaving her at home.

"So, I think it's okay if I do this thing with the press, as long as I am with you."

Castle rises from his seat and hugs her immediately.

"I am sorry. I am so sorry. I've missed you too. And I love you, you know that right?" He kisses her softly.

"I know. Damn, hormones. See? Right here? These are tears. I don't understand my body anymore."

He laughs. "You're so cute when you do that."

"Ha. Ha. I love you too, anyway."

"Always." Castle says, and he gives her a kiss on her temple.
