Disclaimer: The only part of Castle that I own is the TV on which I watch the show.

Dad was driving and Mom turned around to look at me in my car seat. "Eliot, you be a good boy. Scrapple, you too. I know you love Perlmutter so I'm sure that you will be. Dad and I have to go to a wedding today. I'm sorry it's just for grown-ups, but I bet that you'll have more fun than we do."

Dad made a face. I could see him in the mirror. "You can say that again."

"I bet Scrapple and I have more fun than you do!" That was my joke on Dad because I said what Mom said again.

Mom turned her head back around so fast that her hair almost hit the ceiling. "Castle!"

"What? Tell me that you're looking forward to a wedding in an enormous yurt in a parking lot, and a vegan reception? With a band that plays lutes and mandolins and autoharps?"

"It's not in a parking lot."

"My mistake. A dirt-and-gravel area that abuts a parking lot. Where did they find a yurt in Yaphank, Long Island, anyway?"

"At Hertz Rental Yurts."

Dad snorted when Mom said that, I don't know why. She put her hand on the back of his neck and scratched his hair.

"And Castle?" She sounded kind of gooey.

"Yes?"

"I have a sixteen-ounce bag of peanut m&m's in my purse."

"Every day, yet another reason to adore you."

And right that minute we were at Docky's building and he was standing in front waiting for us. Dad got the stroller and a bag out of the trunk and Mom got Scrapple and me out of the car.

"Thank you so much, Sidney. I can tell that Eliot is excited to be here since he has already latched on to your knee. Not to mention the shrieking the instant he saw you from the window." Mom looked down at me. "Could you let go of Doctor Perlmutter, please, so Dad can put you in the stroller?"

"Hi, Eliot. If you sit in there, you and Scrapple and I can go upstairs to my apartment and then we're going to do something new, okay? All three of us."

"What are we going to do?"

"You're sure you're all right with this, Kate? Castle? We won't go fast and it's very safe, but I just want to make sure that you have no concerns."

"You're a doctor," Dad said. "I'm confident that they're in good hands. Don't forget to take pictures."

So Mom and Dad left and we went up to Docky's. Right there next to his front door was his bicycle with the trailer attached to it, the one he told me about on my birthday. Docky held up the bag that Dad had given him. "Your helmet and Scrapple's helmet are in here, so we'll put your stroller inside, and we'll all get our helmets on and be off to the park."

Docke buckled Scrapple and me into the bicycle trailer which is blue like my helmet, and pushed us along until we got out onto the street.

"Are you boys ready?"

"Yes! This is my first bicycle ride!"

"Yeah! Same here."

And we zoomed along past the buildings and trees and trucks and cars and fire hydrants and trash cans and pigeons and people and dogs walking and bingo! (that's what Dad likes to say) we were in the park. It was fun to go so much faster than in the stroller, and to get to have Scrapple next to me. His ears went out sideways in the wind and he looked like an airplane. After a while Docky pulled over to the side near a big rock with a statue on top of it and stopped so he could talk to us.

"That's a dog!"

"Doesn't look like me, though."

"You're right, it's a statue of Balto. He was a wonderful and very brave Siberian husky who led a lot of other sled dogs through the snow to bring medicine to people in a place called Alaska. He saved their lives and this statue helps remind us of what an important thing he did."

"Could Scrapple pull a sled?"

"My legs are too short. I'd get stuck in the snow."

"Why is Balto's nose so shiny?"

Docky laughed. "That's because so many people have rubbed it."

"Why do they do that?"

"Probably because they like him. Maybe it's their way of saying hello and thanking him for what he did. Maybe some people do because they think it's good luck. Scrapple, why don't you and Eliot stand in front of Balto and I'll take your photo. I'll take off your helmets first, though."

He did, and then he showed us our picture. "You boys look very heroic. Intrepid."

"I thought intrepid was an aircraft carrier. Eliot and I don't look like an aircraft carrier."

"You're very wise, Scrapple. The Intrepid is indeed an aircraft carrier that's now a museum right here in the city, on the river, but the word intrepid means adventurous."

"We're adventurous. We're on an adventure today."

"That's right, we are, so let's get back on the bike and see more of the park."

We rode all over the place and then we stopped for a while and got to kick some leaves around and Scrapple peed. And then we all sat on a bench to have a snack.

"Thanks for the biscuit, Docky."

"You're welcome, Scrapple."

"Is that bicycle trailer big enough for two children and a dog?"

"Yes, it is. Do you think we should invite a friend of Eliot's to come with us next time?"

"No, I was just thinking that after Eliot's brother or sister is born, the baby could come, too."

"Scrapple! That was a secret! We weren't supposed to tell."

"Oops, sorry. I thought it would be okay to tell Docky since he's our friend and besides he's a doctor."

"Oh, my. Look, I promise I won't tell anyone. Your secret's safe with me. But that's great news, isn't it?"

"You know what, Docky? I can talk to the baby and it talks back to me. I want to call it a name, not just Baby. Maybe you can help."

"I'll try. Have you been thinking of some names?"

"Yeah, but I need to find out something. The baby is going to be born at Easter, and I like rabbits, so I thought I could call it after the Easter Bunny."

"You want to call the baby 'Easter Bunny'?"

"No, that would be silly. I want to call it the first letters of Easter Bunny, like our friend Matthew John is called MJ. Could you tell me the Easter Bunny's first letters?"

"Sure. First letters are called initials, and the Easter Bunny's initials are EB. That's a good nickname, EB. And it's one of your initials, too, E, E for Eliot, so the baby can share part of your name."

"What's my initial?"

"S. Scrapple begins with S, like my name, Sidney. So you and I share, too."

"Since you can talk to Scrapple and me, do you think you could talk to EB? Not now, but after Mom and Dad tell everyone? I think that''s going to be pretty soon because this morning Mom said, 'I can't keep this a secret much longer, Castle. I'm popping out of everything.' I don't know exactly what that means, the only pop thing I know is popcorn, but she said secret, so I think it's the baby, don't you?"

Docky coughed a lot and took out his handkerchief and blew his nose.

"Are you okay? Do you have a cold?"

"No, I'm fine, thank you. I must have swallowed that bite of apple wrong. Well, to answer your question, maybe you should be the only one to talk to EB for a while. Once the baby is born, though, I will be very happy to talk with him or her. I'm sure we'll understand each other perfectly, just like you, Scrapple and I do. And then we can be the three musketeers plus one."

"Plus One! That's funny! That was my name when I was inside Mom. Because she had her vest that said POLICE + 1."

"Oh, I remember that vest. Well, let's ride a little more before we head back to my apartment?"

We did, and even though it was exciting, near the end I fell asleep and so did Scrapple. We woke up when we were in Docky's elevator. And then it started to rain so it's a good thing we were indoors, where we had lunch and a nap and played and read a book called Pretzel which is about a dachshund. And then Mom and Dad rang the doorbell, and it was time to go home.

When we got there Mom said the wedding had worn her out and she was going to lie down on the sofa for a while. I wanted to talk to the baby, so I got up with Mom.

"Hi, Baby, how was the wedding?"

"Boring. I didn't have anyone to talk to."

"Did you get cake?"

"Yes, but it was horrible."

"How can cake be horrible?"

"All the food was horrible. Dad told Mom he had to spit it in his napkin. And then he had to find another napkin to spit more food into."

"I bet Mom will eat something you like later, like ice cream. But wait 'til you're out of there and they make you eat oatmeal. It's super horrible. But you know what?"

"What?"

"I have a name for you now so I won't have to call you baby. You're EB, okay? Short for Easter Bunny, who is a magic rabbit who brings candy at Easter, which is when you're going to be born. Do you like your name?"

"Yeah!"

"I'm going to go get my favorite toy to show you. It's Peter Rabbit, who is a bunny, too, but in a book. Dad gave him to me the day I was born. I know you can't see in there, but maybe you can feel him on Mom's belly. I'm going to get him, he's right over there on the rug."

So I got down all by myself and picked up Peter Rabbit and brought him back and put him on Mom's belly. But you know what? She and EB were asleep so I left Peter Rabbit there. I hope EB can feel how soft he is.

When I went to bed later Mom and Dad tucked me in and just when I was falling asleep I heard her say, "Eliot left Peter Rabbit on my stomach. He never leaves him behind. What do you think that was about?"

I have to remember to tell her.

A/N EB joins Eliot in thanking you for reading their story.
