Lexie could hardly believe that today was the day. She and Mark were finally going to tie the knot and she would become a Sloan officially, joining Mark and their son with the same last name for the first time. They had been counting down the days since he had proposed the day their son was born almost twenty months ago, but Mark had been patient enough to allow her to get through residency and take her boards before the wedding.

Like everyone expected, Lexie passed her boards with flying colors and had accepted a fellowship with Seattle Grace-Mercy West under Derek in the Neuro department. She was proud the day she got her navy scrubs and was offered positions in Seattle, Boston, Houston, Los Angeles, and New York. But Seattle was home. It was where she fell in love and where her family was, though Mark told her time and again that they could move anywhere she wanted to begin her career. But she wanted to stay close to home, so Greyson could grow up with his cousins close by.

"You look absolutely perfect," April gushed, fussing over the last few details as Lexie came out of her thoughts. "Mark won't be able to take his eyes off of you today."

"Well Jackson can't keep his off of you," she retorted with a smile.

"I…we…it's complicated," her friend stuttered. "I don't know what we are and it's been that way for a while, since I took my boards the first time."

Lexie put her hand on April's. "Don't let things be complicated. If you love him and he loves you, then let it happen. Don't make the same stupid mistakes that I did with Mark because it just causes a lot of heartache when you try to pull away from the one you love."

Her friend nodded in understanding. "I just got scared. Jackson…he was my first and then I really fell in love with him."

"Then you're one of the lucky ones that find it with just one shot," she said delicately as she fixed her veil. "Jackson is a really great guy and someone that has been my friend through a lot."

April smiled and helped arrange the last of Lexie's curls into place before she was really ready. She had been so thankful for April's help during all the wedding planning and knew that she would return the favor one day when April got married too, if and when that happened. Her older sister handed her the flowers that were waiting before hugging her.

"You look gorgeous," Meredith smiled. "And I think it's time."

A deep breath gathered in Lexie's chest before she exhaled and nodded. Zola and Sofia looked so cute in their flower girl dresses while Greyson looked so handsome in his little suit, just like she knew Mark looked incredible in one too. The Sloan men were all so handsome and Lexie felt lucky to be their wife and mother. Everything was ready and so was she, except for one thing. Her mother wasn't here. And that hurt Lexie quite a bit when it hit her as her father came in.

"Dad…" she breathed, holding back her tears as he came over and kissed her cheek.

"You look beautiful kiddo," he told her, smiling as he hugged her.

Thatcher Grey was not a perfect man, by any means, but he was her father and he had done his best to get his life together in light of losing her mother. He had been sober well over three years now and was a great influence in her son's life, as he adored his grandson dearly. Greyson had taken a particular liking to his grandfather and loved how goofy he was from time to time.

"Thank you, Dad," she said genuinely, holding onto him for a moment and wishing that her mother could be here to witness this moment.

"I have something for you," he said, pulling back and reaching into his coat pocket to pull out a necklace Lexie was all too familiar with.

"Oh Dad…" she gasped. "That…that's the necklace you gave Mom on your wedding day."

Thatcher nodded and held it up. "She would have wanted you to have it on your special day and to keep for your future daughter, someday."

Moving her hair, she let her father put the necklace on and held back her tears again. "This is going to be my something old."

Her father gave her a genuine smile. "You look so much like your mother sometimes. And she would have been proud of you, for all your accomplishments and for the beautiful family you have."

His words brought tears to Lexie's eyes and she was thankful she had waterproof mascara and eyeliner today, since this probably wouldn't be the first time she had tears in her eyes from happiness or reminiscing about the things that were important to her and Mark's life. Lexie wished that her mother could have seen her go on and become a doctor, fall in love, have a child, and get married, but she knew undoubtedly that her mother would be here today in spirit, watching over them just as she was the day Greyson was born. And that was the important thing to remember as she fixed her veil one more time and held her flowers in her hand, taking a deep breath as everyone else filed out of the room. Derek and Jackson had come by to get Meredith and April to go down the aisle first, but soon enough, it was her turn.

Holding onto her father's arm, Lexie made her way into the chapel and held her breath as the doors opened. The chapel itself was beautiful, with the flowers she had chosen for the wedding draped on the seats, and the arch at the front, waiting for her…right along with Mark. He was so handsome in his tuxedo and she couldn't keep her eyes off of him as she walked down the aisle with her father. When they made it down to the front, she could see how happy Mark was as Thatcher gave her away and placed their hands together.

"Welcome friends, families, and honored guests. We are here to celebrate love. Love organizes our large and sometimes unpredictable world. It is that which enshrines and ennobles our human experience. It is the basis for the peace of family, and the peace of the peoples of the earth. The greatest gift bestowed upon humans is the gift of love freely given between two persons," the officiant began, looking at Lexie and Mark. "We gather here today to witness the joining of two lives together. Mark Everett Sloan and Alexandra Caroline Grey have come together, freely of their own will, to be joined together in matrimony. And we all bear witness to this prestigious occasion for them."

While the officiant began their ceremony, Lexie kept her eyes on the man she was going to spend the rest of her life with. His hands were warm and comforting as he held hers and looked back in her eyes, smiling and mouthing 'I love you' to her. She was completely happy in this moment and knew that she had the best man possible to spend her life with.

"All of you are present today because you, in one way or another, have been part of Lexie's or Mark's life. On behalf of the bride and groom, a hearty welcome to all. Today we witness a marriage that began with a single look and one little intern telling off her boss. From there grew one of the most beautiful and complicated love stories, but it is their story. And one they want to share with all of their family and friends today. Lexie and Mark have also chosen to express their love in their own vows."

Mark looked at Lexie and smiled. "The first time I ever saw you, I had no idea how much you would change my life; Or how you would be the woman that I fell in love with completely and totally. Admittedly, Derek was the reason that I ever took interest because he forbid me to talk to you, but in defying his wishes, I met the most amazing and wonderful woman I've ever known," Mark said, holding her hands. "Lexie, you challenge me in so many ways and have given me the most remarkable life with our family. And you've forgiven my faults, still loving me despite the many times that I messed up and hurt you in the past. The life we have together isn't one I would trade for anything else in the world, so today I'm promising you the rest of my life. To be your husband, faithful and true to only you, for better or worse, richer or poorer, sickness or health, til death do us part. I love you, Lexie, and we were always meant to be."

When it was her turn, Lexie smiled and took a breath. "Moving to Seattle after medical school was the last thing I thought I'd ever do, but it turned out to be the best decision I ever made because it lead me to you. As surgeons, we say we don't believe in fate, but I think that somehow…fate brought me to you," she began, squeezing his hands with her own. "Most people would look at us and wonder how a couple that is so different could be together, but as I once said, most people don't know us. And we have always adapted to a hostile environment, right from the beginning. You are the love of my life and my soul mate, giving me the most beautiful life with you and our family, no matter how many ups and downs we've had in the past. So I'm promising you everything today…my life, faithfulness, heart, and soul until the day I day as your wife, soul mate, and life partner. I love you, Mark. Always have and always will."

When their vows were said, the officiant looked to Lexie. "Do you Lexie, accept this man, Mark, as your husband — joining with him today in matrimony — offering your friendship and loving care — honoring his growth and freedom as well as your own — cherishing and respecting him, loving and embracing him in times of adversity and times of joy? If so, answer now, 'I do.'"

Lexie smiled. "I do."

"Please repeat after me: With this ring, I thee wed. Take it as a sign of my everlasting and unconditional love with all that I am and all that I have from this day forward as your wife."

She repeated the words and took the ring from Meredith, sliding it on Mark's finger as she did.

The officiant turned to Mark next. "Do you Mark, accept this woman, Lexie, as your wife — joining with her today in matrimony — offering your friendship and loving care — honoring her growth and freedom as well as your own – cherishing and respecting her, loving and embracing her in times of adversity and times of joy? If so, answer now, 'I do.'"

"I do," Mark replied, keeping the smile on his face.

"Please repeat after me: With this ring, I thee wed. Take it as a sign of my everlasting and unconditional love with all that I am and all that I have from this day forward as your husband."

Mark also repeated the words as he took the ring from Derek and slid it onto her finger, looking up at her as he did.

"Love freely given has no giver and no receiver. You are each the giver and each the receiver. The wedding ring is a symbol, in visible form, of the unbroken circle of your love, so that wherever you go, you may always return to your shared life together. May these rings always call to mind the power of your love."

Her heart was beating faster as she felt the nearing of the words she had waited to hear all day long and every moment since she accepted Mark's proposal over a year and a half ago. Every single moment of their relationship had been leading up to this moment and Lexie knew that with the pronouncement of their marriage, they would begin a new step in their life as a family. But right in that moment, like all Greys and Sloans, their son decided to make the show about him.

"Mama hol' me!" he cried, moving away from where Meredith had been holding his hand to come over and raise his arms up.

Everyone seemed to think that was the cutest thing in the world as they murmured in the crowd. Lexie didn't hesitate to let go of Mark's hands for a moment to pick up their son to hold him on her hip. No one seemed to mind either since they all knew that she and Mark had a family. Greyson was perfectly content to lay his head on his mother's shoulder and look over at his Daddy, who was grinning at him and reached over to rub his cheek.

The officiant didn't miss a beat. "Lexie and Mark, in the presence of your family and friends who have joined you to share this moment of joy, you have declared your deep love and affection for each other. You have stated your wish to live together, always open to a deeper, richer friendship and partnership. You have formed your own union, based on respect and honor. Therefore, it is my joyful responsibility to officially acknowledge your union as "Husband and Wife." You may now seal your marriage with a kiss."

Without hesitation, Mark leaned over and kissed her. She moved her free hand to his cheek and kissed him back with all she had, their son right between the two of them as he had always been. The cheers and applause from the crowd made her blush a little as they broke the kiss and he took her hand into his own as Meredith helped move her dress behind her. When she offered to take Greyson, Lexie shook her head and smiled, knowing that he had been a part of them since the moment he was conceived.

"Ladies and Gentlemen, it is my privilege to present to you for the very first time, Mr. and Mrs. Mark and Lexie Sloan!"

They made their way back up the aisle together before they were given a few moments of privacy. Mark held her in his arms and kissed their son's head. For a few moments, they were just a little family and Lexie liked that. It was nice to have the privacy for a little while and Lexie enjoyed those moments where she could just kiss her husband and hold her son in her arms before the madness of photos ensued. Once the official photos were taken and everyone was ready, they all made their way to the reception, which was close by. Everyone was introduced and came in accordingly before she and Mark made their entrance and took their seats.

Dinner was served and almost everyone was having fun just talking, laughing, and mingling with one another. And even the little ones, who were all together at the bridal table since their parents were in the wedding, were having fun giggling and making each other laugh. Lexie would have never imagined having her own child at her wedding, but couldn't think of it any other way now that Greyson was in their lives. He was so precious and she knew she would treasure these memories with him.

When she and Mark were called to do their first dance, she took Mark's hand as he held it out to her and went out to the dance floor. Being held in his arms was a comforting feeling as she rested her forehead against his and danced around while pictures were being taken of their first dance.

"Today was perfect," she murmured to him, realizing how happy she was.

Kissing her head, he smiled. "I thought so too…you look absolutely gorgeous, Lex."

"I wanted everything to be perfect for us today, so when I saw this dress…I just knew," she replied, looking up at him before she kissed him.

"Well today was perfect. And I can't imagine spending my life with anyone else but you, Lexie…you've given me everything and so much more."

"I have one more surprise for you today," she said, looking up at her husband as they were dancing and everyone had joined them on the dance floor.

"A surprise?" he asked, looking down at her as he arched a brow.

Lexie nodded and leaned in close to whisper in his ear. "I'm pregnant."

Mark stopped, completely surprised as he looked at her with a grin before kissing her. She knew he was happy with the news and there were no words needed in that moment. They were happily married, had a son, and were now going to welcome a second little one into the world early next year. Lexie couldn't have imagined a better life for herself as she danced the night away with her husband, celebrating what they had built together and what was to come.

A/N: Like that little surprise at the end? I thought you guys might. Review and let me know! The next chapter will be the last for this story as I bring it to a close, so I wanted to thank you all for being on this journey with me.
