A/N: THE FINAL CHAPTER

Six-year-old Mackenzie Hunt was in her room, admiring her pretty blue dress. Today was a special day as she, Momma and Daddy were going to Anna and Zach's graduation from high school. Anna and Zach were now 17 and were joint valedictorians of their graduating class. Zola and Sofia were also graduating, so it was going to be a huge gathering from Seattle Grace at the graduation.

If Anna and Zach were replicas of their parents, it was Mac who was the true hybrid. She had her mother's long dark curly hair and full, pink lips, combined with her father's blue eyes.

"Hey there, squirt," Zach said, as he looked into her room. "You looking at yourself?"

"Yes, Zach," she told her tall redheaded brother. "This dress is so pretty. When I got it for my birthday from Aunty Meredith, I knew that I was going to wear it to your graduation."

"I am so honored, Mac," Zach said. "In any case, Anna and I headed down to school, since we both have speeches and we have to do sound tests. I already told Momma, so I will see you there."

"Okay, Zach. Bye," Mac said as she continued to admire herself.

A couple of minutes later, her daddy came down to her room. "Mackenzie, I am here to brush your hair. What do you want to do today?"

"I think I am going with a white headband and have my curls loose down my back," she said. Owen was amazed how his daughters always knew exactly what they wanted. They probably got that from their mother, he thought.

As he brushed her hair, Owen marveled at the thought that his two oldest were graduating from high school, while his youngest would only be entering the first grade in the fall. In a move to appease their parents, Anna chose Harvard (like her dad) while Zach chose Stanford (like his mom). They were both going off to college and it would only be Cristina, Owen and Mac left at home.

"Mac, you do know when Zach and Anna go off to college, it will only be you on this floor," Owen said. "Is that okay with you?"

"Yup, I am not afraid. I will have it all to myself. They won't be around telling me not to touch their things. I will go in their rooms and touch anything I want," she said. "But they'll be back for all of the holidays, so that won't be so bad."

"Okay, then. But if you ever want to come up and see Momma and me, you can, if you want," he said.

"I know but I will be okay. Don't worry, Daddy," she assured him. "Also, Zach told me that I shouldn't bother you and Momma when you're wrestling. He says you don't like to be disturbed."

Owen wanted to laugh. "So Zach said that, did he?" That Zach was a wise young man, Owen thought.

"There we go, I am done. You look so pretty, Mac," he said, as he kissed her on the nose. "Let's just go find Momma and we will head out to the high school."

The crowd had already started taking their seats when Owen, Cristina and Mac arrived.

"Can you see them?" Cristina asked.

"Yes, there they are," Owen said, pointing out his twins for his petite wife.

"Oh, there's the gang. Let's join them," Cristina said, as she ran to hug Meredith.

The whole Seattle Grace contingent was sitting all together – Meredith, Derek and 13-year-old Damian; Arizona and Callie with 14-year-old Gabriela and 11-year-old Catalina; Mark and Addison with 14-year-old Morgan and 13-year-old Willow; Alex (the twins' godfather) and Izzie with six-year-old Lily Beth, their youngest. Lexie was there to see her niece Zola graduate but Jackson wasn't, as he volunteered to stay at home with Alex's four boys, in addition to his two kids.

Mac was excited to see Lily Beth and ran to talk to her friend. The two girls happily sat next to each other. They were both going to be in the first grade in the fall.

"I hope we get some good pictures of the kids," Cristina said.

"Of course, we're getting the best pictures. Our kids are the co-valedictorians," Owen said, as he took out his camcorder and handed the camera to Cristina.

After all of the awards had been given out and all of the officials and guest speaker had spoken, it was time for Anna and Zach's speech. They had written it together. Anna was going to deliver the first half and Zach was going to finish it.

After giving her salutary greetings, Anna started, "Today, my fellow graduates, marks the end of our time at West Seattle High School. It has been a great run for our class. Who can forget the spring fling, the junior prom, the senior prom, homecoming games and the bonfire nights? And for the geeks like myself, winning the math Olympiad, the science exposition and the regional chess championships were among the highlights. My brother would like me to mention that he was part of the team that won the lacrosse championship as well as he was named the top fencer in the state in his age division. Is that good, Zach? (Zach nodded, while everyone else laughed).

"Yes, today marks an ending for all of us. But it is also a new beginning for all of us. We say goodbye to our childhood and hello to adulthood.

"All of us are going to colleges all over the country and for many of us, it marks the first time we will be separated from our families and friends. My twin brother, Zach and I will be separated on opposite sides of the country for the first time in our lives. We still don't know how we're going to survive it. We have been together forever, from the womb till now. That's a long time to share everything with another person.

"Being separated from our friends and families is going to be very hard. But we do know that it is going to allow us to stand on our own two feet, help us become independent and force us to make our own decisions, right or wrong.

"We're going to make a ton of mistakes but mistakes are how we learn. Those were the words of a wise man, namely my dad, Dr. Owen Hunt. Like the rest of you graduates, our parents have been the biggest influence of our lives. Indulge us a bit, as we talk about the two people who have made the greatest differences in our lives.

"My dad has over the years been a fount of wisdom and good advice for the two of us. He has been the steadying hand that has guided our family over the years. When the rest of us were flailing through our crises, big and small, my dad has been the rock to which we have clung. He has always been our family's hero. Thank you, Dad.

Anna stepped back and let her brother take the podium. Zach continued:

"But it is our mom, Dr. Cristina Yang, who has instilled in us the drive and ambition that we both have. My mother won the Harper Avery award three times, a feat that has yet to be matched by anyone. She always made us strive to be the best that we can be. I guess maybe that's why we both ended up being co-valedictorians today. She would accept nothing less than an A from either of us. After all, she was a straight A student for her entire life, so we had to be, too. Anna and I were competitive with each other from the start and throughout the years, we would always compete to see who could win the coveted trophy for the top student of each grade. God forbid that any other child could ever win that trophy, except for a Hunt. (The audience laughed).

"Thank you, Mom.

"Graduates, take a good look at your parents. These are the people, who have raised you, and show them the gratitude that they deserve. Without these people, we would not be who we are and where we are today.

"So, this is it, my fellow graduates. We're leaving West Seattle High today. Thank you to our teachers and Principal Hastings for all that you have done for us. Let us grab the opportunities that this fine education has allowed us to achieve, as we continue our academic careers at college in the fall. We will always have good memories of this place but let us make even better memories, as we look ahead to the future.

"We thank you all."

Cristina could not feel any prouder of her twins. Her eyes were misting over, even though she was taking as many pictures as she possibly could of her grown-up babies. She could see that Owen was crying, too, even as he filmed everything with his camcorder.

She looked at their friends, Meredith, Derek, Mark, Addison, Callie, Arizona, Alex, Izzie and Lexie. Each of them was shedding a tear, though the men were trying to hide it.

At the reception held for parents and graduates, Owen turned to Cristina, "We did good, baby. We raised two fine young people. "

"Yes, we did, Owen," Cristina said.

Zach came running to them. "Sofia's moms are throwing a bash for all the kids at their house. Can we go?"

"Yes, Zach. Just come home by midnight, " Owen said.

"Okay, Dad," Zach said, running back to tell Anna the good news.

"Well, it looks like it's just going to be us at home tonight," Owen said. "Zach and Anna are at Callie and Arizona's house, and Mackenzie is having a sleepover with Lily Beth at Alex and Izzie's place. And we have the place until midnight all to ourselves. Do you have any idea what we could do with all that time? Hmm. I wonder."

Cristina grinned. "Feeling a little frisky, old man?"

Owen retorted, "Who are you calling old? By the way, Zach told Mac that she shouldn't bother us when she sees us wrestling because we do not like to be disturbed."

"Ready, Dr. Hunt, for a little bit of wrestling?" she said.

"You mean a lot of wrestling," he grinned.

He took her hand into his, as they headed to their car.

"I love you, Dr. Hunt."

"I love you, too, Dr. Yang."

THE END

A/N: Thank you to all who have come on this journey with me. So the show didn't give us the happy ending we were looking for in terms of the baby. But we can always have our own happy endings in fan fiction.

Please leave your reviews. They mean so much to me.
