I do not own any of these characters besides PJ. In this chapter, PJ is 7 years of age.

Isabella was shaking in her seat at the kitchen table. Her husband, who was sitting next to her, put his hand on her shoulder to keep her still, but the excitement was too much. Both Phineas and Isabella were all too eager to tell their son the news as soon as he gets home.

"Phineas, I don't know how he will react."

Phineas turned to his wife and patted her hand in support. "Isabella, our son has been feeling lonely for a while. This new addition to the family will help him. He will love to hear this."

Just then, the door from the garage to the kitchen opened up. PJ entered after a long day at school.

He smiled at his parents. "Hey Mom, hey dad." He greeted, setting his backpack. He walked over to give his mother a hug and a kiss, before going over to his father for a high five and a hug.

"Hey, pal. How was school?"

PJ chuckled, "Winnie got into another fight."

Phineas scoffed. "What is up with her?"

"Maybe I should teach her a lesson if Ferb isn't going to do anything," Isabella remarked.

PJ laughed as he walked over to the fridge, taking out a juice pouch.

"Son, can you please take a seat?" Phineas asked, pointing towards the chair adjacent to him. PJ turned and raised an eyebrow, but smirked as he knew he wasn't in trouble. Perhaps what his parents had to say might be interesting.

"What's up," PJ asked, taking a seat next to his father.

Phineas sighed. He faced to his right at his wife, before turning to face his son, putting a hand on PJ's shoulder. "Son...you know your mother and I love you both love you dearly."

PJ smiled and blushed a little. "I know, dad, and I love you both, too."

Phineas nodded and spoke. "You see, with the three of us, it can get lonely here."

PJ looked around the kitchen. "You're actually right. This house is big for the three of us."

"Exactly. Which is why your mother and I have some news for you."

Phineas and Isabella both looked at each other with eager smiles before turning to PJ with eager smiles. "We're having another baby!" They spoke simultaneously.

PJ's jaw dropped at the news, trying to take in what his parents had just told him. He couldn't believe this. They...they are going to have another child.

What PJ recovered from his state of shock, he began to smile wide. He hopped from his seat and laughed as he embraced his father.

"You're happy?" Phineas inquired.

"Happy? I'm beyond that. I can't believe this!" PJ pulled from the hug, before going over to hug his mother.

Isabella hugged back. "I'm so happy you're okay with this, hon."

PJ pulled back. "Is it a boy or a girl?'

Isabella shrugged. "Guess you're gonna have to wait for a little."

PJ moaned but returned to his happy mood. He ran upstairs to get his phone to call all of his friends and cousins about the news. He was going to be a big brother.

9 months later...

"Dad, you're were over this 8 years ago."

"I know, son. But I'm still nervous."

PJ sat next to his father in the waiting room while his mother was in labor. He was reading a comic book when he looked over to his left and saw his father scratching his beard and shaking ecstatically. Phineas's breath was uneven and he was feeling sweaty.

"Dad...calm down."

"I can't son," Phineas exclaimed, "what if this child doesn't turn out right?"

"The child will be fine."

Phineas raised an eyebrow and his son. "Oh really?'

"Yeah. I mean, I'm alright, am I?"

Phineas shrugged. "I guess so."

PJ smirked and set his comic book aside. He leaned and snuggled with his father. "It's gonna be fine, dad. The baby will grow to love you the same way I did.

Phineas looked down and smiled at his son. "Thanks." He grabbed PJ's left hand and placed a kiss on it. "Y'know, I love you, son. Right?"

PJ wrapped his arms around his dad's waist. "I know, and I love you too."

As the duo was enjoying their moment, Phineas noticed from the corner of his eye a doctor walking over. Both Phineas and his son stood up.

"Sir, is my wife?"

The doctor smiled. "Your wife is fine, Mr. Flynn. As for your newborn daughter..."

Phineas' eyes grew wider. PJ's breath was taken away. A newborn...girl?

PJ moved forward and began pulling on Phineas' hand. "Let's go, dad. Let's go meet my new sister."

Phineas was still in a state of shock, but he nodded his head slowly. He followed the doctor and his son until they reached the room Isabella was in. When they walked in, Isabella was sitting upright in her bed, holding a small blue bundle.

Isabella looked up and smiled wide at her husband and son.

"PJ, come over here. There's someone I want you to meet."

PJ nodded nervously and walked over next to his mother to get a peek of the baby. His breath was taken away. His new sister was so peaceful looking. She was still a pink color, and her eyes were closed. She had the head shaped similar to Isabella, but the one thing that stood out was the red hair, which obviously came from Phineas.

Phineas stood behind PJ and took a glimpse of his daughter. "She's beautiful." He whispered, already overcome with emotion.

"She really is," PJ added. He looked at his mother. "Can I hold her?"

Isabella looked up at Phineas, who gave her an approving nod. Isabella then looked at her son and handed the bundle over to PJ. PJ very carefully picked the bundle up and held his baby sister. He smiled at her adorable face, but then gasp as she opened her eyes and looked up at him.

"Hi..." PJ whispered, "I'm Phineas. Phineas Junior. But you can just call me...PJ. I'm...I'm your new brother."

Isabella couldn't help but tear up at the sight of her son holding her newborn daughter. Phineas looked down and smiled at his son. He puter both hands-on PJ's shoulders.

"How is she?" Phineas asked.

"She's beautiful," PJ said. He looked up at his mother. "What's her name?"

Isabella pursed her lips, thinking for a bit before smiling at her son. "I'm gonna let you choose."

PJ thought for a moment, looking down at his baby sister. He held her closer and spoke softly. "Lilly. Lilly Flynn."

Isabella and Phineas were dumbstruck before thinking about it. Lilly...that name fits that baby girl so well.

"Lilly? I like it." Phineas spoke.

"Me too," Isabella added.

PJ smiled and handed the bundle over to his mother. The three cuddled together with the baby as the nurse stood at a fair distance to take a picture.

Welcome to the family...Lilly Vivian Flynn.

So was that a sweet chapter. Yay, a new character! I wonder what I can do with Lilly.
