Karen ran down the staircase, quickly trying to put her shoes on. It was Cailyn's birthday, and she was waiting for Will to bring her back to the manse after their sleepover at his apartment. She walked into the kitchen to find Rosario when Will let himself in.

"Karen?"

"I'm in the kitchen, hang on!" came a disembodied voice.

"Come on, Mommy! We're gonna be late to the zoo!"

Just then, Karen swung open the door, holding her arms out to Cailyn. "Hey birthday girl! Did you have fun last night?" She asked as Cailyn ran to her and gave her a big hug.

"Uh-huh. Daddy and I watched movies and made cookies and then Aunt Grace came over and ate them all!"

Karen raised her eyebrows. "Oh, no! Did she really?"

"Uh-huh. But it was okay, then Uncle Jack came over and took me out for ice cream."

"Sounds like you had a good time! Ready to go see Uncle Stan?"

Cailyn nodded her head vigorously. "Okay, say goodbye to Daddy. He'll be here when we get back." Will gave her a hug and a kiss and watched as the two of them left to go meet Stan.

"Happy Birthday, Cailyn!"

"Thanks, Uncle Stan! Can we get some popcorn?"

Stan looked at Karen who shook her head. "Come on, Kar, why not? It's her birthday!"

"Why not? How about because it's ten o'clock in the morning?"

"Fine." He leaned down and whispered in Cailyn's ear "I'll get you some when Mommy's not looking." She looked up at him and smiled, kissing him on the cheek.

"I heard that." Karen said, sidling up to Stan's side, as Cailyn ran ahead of them to the next cage.

"You heard nothing." Stan said with a smirk.

"Thanks for doing this, honey. She's been looking forward to this all week."

"My pleasure. I didn't get to do this sorta thing with Olivia and Mason, and it's actually kind of fun." Stan said. "I really look forward to seeing her, too."

Karen smiled. "I'm glad. I'm sorry that things couldn't be simpler, Stan. Really, I do."

Stan smiled back at her. "I know, Kare. But hey, once she gets a little older, maybe we can tell her and she'll understand, right?"

Karen nodded. "Cailyn! Do not climb on the fence! What did Mommy say about that?" Karen said in a loud voice as they neared their daughter.

"But Mommy, I can't see!"

"Come here." Stan said, lifting Cailyn up onto his shoulders so that she could see over the bars and into the monkey cage.

Karen smiled as she saw the look of pure delight on her daughter's face. She checked her watch. Eleven-thirty. "Hey, guess what? We've gotta get home! Everybody's waiting for us." She said as Stan set her back down.

"But I wanna stay here!"

"Okay. I'll just have to call Olivia and Mason and tell them that you don't want to have any birthday cake with them." Karen said, whipping out her cell phone and pretending to dial.

"Olivia and Mason are here?" Cailyn asked.

Karen nodded. "Yep, they came to see you for your birthday, but I'll just tell them you're too busy."

Cailyn took her mother's cell phone and closed it, putting it back into her purse. "I'm ready to go, now!"

Stan couldn't help but laugh. He could see that Karen's personality was beginning to shine through in Cailyn. They made their way back to the manse, Cailyn practically dragging them behind her.

"Happy Birthday!" Jack shouted as Cailyn walked into the penthouse.

"Thanks Uncle Jack! Hi Aunt Grace!" she said, hugging them both and walking into the living room.

Will was hanging up a 'Happy Birthday' sign over the fireplace when Cailyn walked in. "Daddy!" she yelled, running into the back of Will's legs. "Guess what? Olivia and Mason are coming!"

"I know, sweetie. And guess what?"

"What?" Cailyn asked with wide eyes.

"So is your cousin Elliot and Grandma Marilyn and Grandpa George!"

"Yay!" Cailyn screamed, running around the living room and jumping into Karen's arms. "Mommy, when is everybody getting here?" Just then, the doorbell rang.

"Now." Karen answered as Cailyn wiggled out of her arms and ran to the door.

Hugs and kisses were exchanged, and finally everyone sat down in the living room, relaxing and eating lunch. Cailyn sat next to Olivia and kept fidgeting while she waited for everyone else to finish their meal. Karen noticed and motioned for her to sit with her.

"I know you're anxious, but don't worry. They're not going anywhere, I promise." Cailyn nodded and kissed her mother's cheek.

Olivia finished her lunch and walked over to Karen, noticing an impatient Cailyn.

"Hey Cailyn, want to go play upstairs while everyone else finishes eating?"

Cailyn hopped off of Karen's lap and began to drag Olivia upstairs. Karen mouthed a thank you to Olivia and leaned back into the couch, listening to everyone chatting.

Several hours later, everyone had left. Karen had just finished getting Cailyn changed for bed. She was just about to tuck her in when Cailyn sat up, a confused look on her face.

"What's wrong, sweetie?"

"Mommy, why do Uncle Stan and I have the same last name?"
