On the count of...three?

An AU Series . What if Castle and Beckett had triplets? What would their lives be like?

Chapter one: 1,2,3

"Three?" Kate Beckett heard herself repeat the doctor's words. She couldn't even look at Castle. Oh no. She wouldn't dare to look at him or she would have to kill him.

And then she would end up a single mother of four.

How in the world had she managed to have four children in four years?

Castle.

"Are you sure?" Rick asked. There was this tone in his voice. So much like Castle and yet he sounded so... Ashamed? Oh god she'd made him feel ashamed for giving her beautiful children? What kind of a person was she?

"Almost certain." The doctor said. "We could do an ultrasound right now if you like, just to be on the safe side." She smiled warmly.

"Yeah, let's do that." Castle put in. Kate smiled at him, for the first time. "You okay?"

"Perfect. I mean... We can handle anything right?"

"Right" He smiled.

Ever since the shooting, conceiving had not come easy. She knew what the doctors had said about Lily when she found out she was pregnant while she and Rick were still recovering.

Lily had been their miracle baby.

And they didn't mind just having the one kid. They also had Alexis. But she knew deep down Castle wanted another baby. Another little girl he'd say, because he wasn't a make boys kind of guy, experience had given him that much. Even if she knew deep down how much he wanted a boy, honestly so did she.

And so Kate complied. And she had this feeling in her gut that Castle would finally get his boy.

"Here we go." She was pulled back to the room where Castle held her hand.

She heard one... Two... She wasn't sure if the last sound she heard could count as a heartbeat but it sure seemed like one.

"There's one baby." The doctor explained. She felt Rick squeeze her hand harder. "And the other not too far behind."

"And there was... I swear I heard..." Kate said. She was afraid to ask.

"It seems there's a third heartbeat." The doctor smiled softly. "Let's see if we can find it again." Kate bit her lip. She was starting to get worried.

And there it was again. It was a bit weaker than the others but it was there.

"It's quite normal for multiples to have stronger babies."

"So something is wrong?" Castle asked.

"Not necessarily." She said calmly. "But I would in fact like to keep an eye on the third baby. Just in case."

"Thank you doctor."

"Any chance of knowing what we're having yet?" Kate asked. Oh it would be crazy if Rick would end up empowered by being the only man in the land full of women his home already was.

"Not yet, it's a bit too early." Dr. Mars said. "I would wait two weeks or so, I'll make an appointment for you then."

Two weeks had been torture. Real torture.

"Three babies?" Alexis had said. "Are you sure?"

"That's what the doctor said." Kate told her. "I was wondering if you wanted to tag along. "Your dad and I have this bet, it would be nice to have a referee when things go south for him."

"What kind of bet?" Alexis was already amused. She knew her dad and Kate too well. Everything or well most of things in their lives had to be a competition.

"I told you Beckett." Rick came from the kitchen. "I don't make boys... I am destined to be surrounded by beautiful women. Beckett heard her toddler laugh. "And Ryan and Espo."

"Dad!" Alexis shivered. "That's too much information."

"Mark my words dear." Castle mused. "None of those babies is a boy."

Then it hit Beckett. If infact her children were all girls then where would that put Lily? She was her and Rick's first. A daddy's girl for sure, full of love and princess tea parties with Castle. How would she feel if she had to share her daddy with not one but three more girls?

"Babe?"" She had said one day while they were in bed. "What if you are right?"

"Right about..." Rick said, his eyes focused on Beckett's as he brushed her growing bump. "About work?"

Kate limited herself to do paperwork mostly nowadays. On Castle insistence. In fact, she had made it a rule of minimum field work unless she had to. It was a promise she'd made Lily.

She'd always come home.

Always.

"No, about these babies being girls." Her tone was serious as she looked up and then to the side at Rick.

"Ah, so you are finally admitting defeat." Rick smirked.

"No Castle, I'm serious, how is Lily going to feel if we come home one day with three little girls, all at once?"

Lily was still a bit too young to understand what babies meant, but she was so smart, she was sure she'd figure everything out in no time.

"Kate. What are you talking about? She's going to love her little sisters"

"No she won't. Not when they are taking her daddy away from princess tea parties." Kate huffed.

The day of the ultrasound finally arrived. How much change could two weeks cause? Kate was sure she'd be having more than 3 babies. This wasn't normal. She was barely four months along and she had blew up like a balloon.

"Kate, how have you been feeling?" Dr. Mars asked as Kate moved up to the examination. "Alexis, it's nice to see you again."

"I've come as a peacemaker. I'm like Belgium. Neutral." Alexis said with a smile.

"Have things been a little tense?" The doctor asked Kate. "You're not overdoing yourself, are you Kate?"

"She has been..." Castle began. Kate shot him a look."What? I just said you should take it easy."

"Dr. Mars... you think we could..." Alexis said softly. "Do the ultrasound?"

"Of course." She smiled. A few moments later as Kate felt the cold gel hit her tummy. The first heartbeat was heard. The image of what appeared to be a little person was a bit more noticeable this time around. "And there's your first. You still want to know the sex, right?"

"Yes!" Castle and Beckett said in unison.

"Well, it looks like you've got your first...boy"

Jackpot

"A...boy? Are you sure?" Rick asked. He sounded really surprised. Kate hit him softly on the side.

"Castle!"

"What? I'm..."

"I'm pretty sure Rick." the doctor said. "Congratulations, even though... well you sound a bit disappointed."

"He's just upset because he lost a little bet." Kate mused.

"I see" Dr. Mars. "I now understand why Alexis is here." She proceeded on with the examination. "Here's another baby...boy."

"Gee Castle I thought you said you only made girls?" Kate smiled tenderly at her husband. "Two out of three"

"Three out of three actually," Dr. Mars explained. "Looks like you are having 3 boys."

"Hear that Rick?" We're having 3 boys."

"I hear it Beckett... and I love you."

"I love you too." Kate kissed him softly.

"Looks like Lily's staying a daddy's girl huh?"

"Yes she is."
