- Chapter 4 -

[ We are Family ]

Elizabeth Shepherd entered the big hospital with her boyfriend and her best friend. They were all excited because the soon-to-be-mom was about the take her first ultrasound. They would have seen a baby in an ultrasound monitor for the very first time in her lives.

"Daddy!" Elizabeth exclaimed as soon as she saw her father approaching them.

"Hi guys" Derek greeted the teenagers and smiled at his daughter "How are you feeling? Excited?"

"I'm so freaking excited!" Elizabeth replied, caressing her belly "Where's mom?"

"She's waiting for you" Derek reassured his daughter and caressed her cheek "Hey, Jason" he continued "You're gonna be a father too. Are you ready for that?" he asked and looked at the boy straight in the eyes.

"Well, Dr. Shepherd" Jason cleared his throat "I've always wanted to be a father. Of course, I didn't expect to become a father this soon but Elizabeth's pregnant now and I couldn't be any happier than this" the boy smiled, his eyes were shining "I'll do whatever it takes to be a good father for our baby"

"You're very mature for your age, Jason" Derek affirmed and hugged the boy "I'm sure you're the best for my little girl but if you hurt her, consider yourself dead" he whispered to Jason's ear.

"I'll never hurt her. I could never hurt her. I love her more than anything else in the world" Jason stated, his voice warm and rough at the same time.

"I know, Jason, I know" Derek chuckled and everybody started to laugh. Jason took his girlfriend by the hand and they all walked to the OB/GYN wing.

Rachelle opened the door of the studio, knowing that the OB/GYN was waiting for them.

"Good morning, Dr. Shepherd" both Jason and Rachelle greeted Addison, who lifted her eyes from the chart she was reading and smiled at them.

"Hey kids" she replied and walked to them. She first hugged Rachelle and then Jason. Those two kids were like the brother and the sister Elizabeth never had and Addison loved them as they were their own children "Elizabeth, are you ready? We're gonna see your baby in few minutes" she added, trying her best to be motherly and happy for her daughter.

"I can't wait!" Elizabeth replied and hugged her mother "Look, I know you're angry" she started "But let's try to be happy, okay? Just for today" the teenager looked at her mother in the eyes "Please".

"We should start" Addison coldly said, guiding her daughter to the ultrasound "Lay down here and lift your shirt" she continued, pointing at the comfortable hospital bed next to the ultrasound.

"Addison" Derek stated "It's our daughter you're talking to. Don't be so professional"

"It's our daughter, our teenage daughter, who is about to have baby. That's the person I'm talking to" the redhead hissed, rubbing a cold gel onto her daughter's belly.

Derek moved closer to Addison and pulled her in a hug. He was the person who knew her the most so he knew that his wife was angry and happy at the same time, he knew that she wanted the best for their daughter and that an unplanned baby wasn't what their daughter needed in that moment of her life.

Rachelle took some steps back and leaned her back against the wall, visibly uncomfortable. She started to feel out of place but she didn't want to leave the studio because she knew that her best friend needed her now more than ever.

Jason looked at Rachelle who gave him a desperate gaze, they both didn't know what to do. Elizabeth, on the other hand, bit her lower lip really hard. She was about to cry but she didn't want to breakdown during her first ultrasound.

"Mom? Dad?" Elizabeth gathered together all her strengths and looked at her still hugged parents "I know you are disappointed and that you're mad at me. But I'm happy. Jason's happy. I promise you we will take care of our little baby and that we won't leave school" she took a deep breath "I still want to be a surgeon, that has been my dream since I was six years old, you know that. I'm not giving up on my dream. It's just… It's just that I'm pregnant and I don't feel like aborting my baby" she wiped away the singe shiny tiny tear that was rolling on her left cheek "I'm a very lucky girl because my boyfriend wants the same things I want and I have the most amazing best friend in the whole world" she looked at Rachelle and Jason and gave them a bright smile "But I'm gonna need my mommy and my daddy. I can't make it on my own" she finally admitted and looked down at her naked belly.

Addison let go of Derek and got down in order to hug her daughter. She hugged Elizabeth so tight that the girl had trouble breathing. The last few days had been awkward and sad. Addison had barely talked to her daughter while Derek had only talked to her when it was really necessary. Furthermore, Elizabeth had heard her parents fighting during the night.

"I love you, Elizabeth" Addison whispered to her daughter "You're my daughter and I'll always be on your side, I'll always support you. You know that" she let go of the teenager and looked at her with a motherly smile on her pretty face "But you can't ask me to be happy about this. I need time, okay? I know you and Jason will be awesome parents and that Rachelle will be there every step of the way but… I've never wanted this for you. This baby will change your life forever and once your child in the world, you'll have to be responsible for this creature. I hope you know that" the woman turned on the ultrasound and rubbed some more cold gel onto her daughter's belly.

"A child is not a Nintendo game" Derek started to speak, his voice warmer than Addison's one "Your mother and I will love this baby the way we love you but if you leave School or do bullshit, well in that case you'll have to make it on your own" Derek and Addison shared a knowing look and he placed a soft kiss on his wife's temple.

"I promise you we won't screw things up" Jason moved closer to the Shepherds and tried to be as convincing as possible.

"I think you two have screwed things up quite enough already" Addison snorted.

"Just give us a chance" the boy continued "We'll prove you we have what it takes to be good, great parents"

"I hope so, Jason. I do hope so" Addison sighed and started to run the ultrasound.

Few minutes later the baby appeared on the monitor and everybody stopped arguing. They heard the first heartbeat of the future Montgomery Thompson baby. They were all staring at it in such an awe. Both Rachelle and Elizabeth had tears in their eyes and Jason squeezed his girlfriend's hand as to let her know that he loved her and their future baby.

"You're already eleven weeks pregnant" Addison let her daughter know.

"Oh, mom. It's so beautiful" Elizabeth's cheeks were full of tears. She couldn't believe that she would have been a mom in six months and she also couldn't believe that she was about to give birth to another person.

"Congratulations, honey" Derek kissed his daughter on the forehead and dried her wet cheeks. It took him all the strength he had not to cry. Angry or not, he was about to become a grandfather.

"Yes, congratulations!" Rachelle exclaimed and hugged every person in the room. She was a very effusive person.

"I love you, Elizabeth" Jason said and kissed his girlfriend on the lips. Then he proudly looked at the monitor. He already loved his baby.

"I love you too, Jason. I love you so much" she squeezed his hand and joined him in looking at the monitor.

"We can't see the sex of the baby yet but if you want we can take a sample of your blood and that way you'll know if you're having a boy or a girl" Addison announced. The heartbeat of her future grandchild still echoing in her head.

"Did you want to know the sex of your baby, mom?" Elizabeth asked her mother.

"What?" Addison chuckled.

"Answer the question" Elizabeth looked at her mother "Please"

"Okay, okay" the redhead laughed "I did want to know the sex of my baby. I've always been a curious person and well, I was dying to know if you were a boy or a girl" she admitted.

"Then I want to know too" the teenager confessed and looked at her boyfriend who nodded at her "We want to know" Elizabeth completed.

"Perfect" Addison affirmed "I'll send a nurse down here and she'll get everything down. Considering it's you we're talking about, we'll know the result in half an hour"

"Thanks mom"

"You're welcome"

Elizabeth stood up and Addison printed the scans of the baby. It was tiny and beautiful. Arms, legs, feet and hands were already there. The eyelids were joint, the iris were forming and all its systems were functioning.

"You're gonna be a great mom" Addison finally said "Not as good as me, though" she completed and everybody burst into laughter. Even if she didn't want her daughter to have a child, she had to accept it, she had to be with her daughter, she had to be the mother Elizabeth expected her to be.

The Shepherds, Jason and Rachelle waited for Elizabeth to have her blood analysis taken and then they all waited together for the results. Half an hour later, they came to know that Elizabeth Juliet Montgomery Shepherd was having a girl.
