I originally posted this drabble on Tumblr yesterday, but I love it so much I wanted to post it here as well. I have edited and expanded it a little from my original post. This is what happened when I stayed up too late studying for my molecular biology exam. I hope you enjoy this! I was giggling like a little girl the entire time I was writing it.
Come to Baker Street immediately. – SH
Please. – SH.
It is important. – SH
Molly stared down at her phone and sighed. She had been looking forward to spending a quiet night with Toby in front of the television. Oh well, she thought. She could not deny that she was excited to see Sherlock. Although they had been together for almost two years, a high-profile kidnapping had kept them apart for the past week and a half. She missed him. Maybe he had finally solved the case.
She hung her lab coat by the door and walked out to the street, hailing a cab and directing the driver to 221 Baker Street. She would find out what he needed, and then perhaps she could convince him to take her out to dinner. Their anniversary was fast approaching, after all.
When they arrived at the flat, she quickly paid and stepped out. Mrs. Hudson quickly answered her knock and directed her upstairs. "Up you go, Molly. Mustn't keep him waiting!" the older woman declared, a giddy smile on her face.
Molly burrowed her brow in confusion as she hurried up the steps. The door was unlocked, and she hesitantly walked inside. "Sherlock?" she called out. The flat was dark, and she was reaching for the light when she noticed him. "Is the case finished? What is going on?"
The man in question stood by the window, bathed in moonlight. She was once again struck by his beauty, and briefly wondered how she was lucky enough to have won his heart.
He turned and gazed at her, adoration evident in his fathomless blue eyes. He slowly walked towards her before grabbing both of her hands in his larger ones and intertwining their fingers.
She had never seen him so exposed, except when he had asked for her help in faking his death. He appeared as though he needed to confess something but was lost for words. She smiled encouragingly up at him, squeezing his hands in reassurance.
Finally, he sighed and stared into her eyes. "Molly, as you very well know, DNA is a nucleic acid comprised of a sugar-phosphate backbone, as well as a combination of only four bases. The two strands are linked via hydrogen bonding. Adenine always pairs with thymine, and guanine always pairs with cytosine."
Well, that was not what she was expecting. At all. She shook her head in bewilderment. "Sherlock, I –."
"Please, Molly, let me finish," he interrupted. At her nod, he continued. "Because of this, every strand of DNA has a complement. There are over 3 billion base pairs in the human genome, but those two strands are perfectly suited for each other." She began to understand what he was trying to say and felt tears well up in her eyes.
"For too many years, I was content to live my life as a single strand of DNA, mocking others who had paired off. Emotional attachments were worthless, and my time was better spent investigating murders and performing experiments. But then, seven years ago, I marched into your morgue, demanding to see the body of George White. Do you remember?"
"Of course, I do, Sherlock," she answered quietly, afraid to ruin the moment. He gulped, taking a deep breath and continued.
"Although I did not realize it then, that moment changed my life. It did not occur to me until I left to destroy Moriarty's network that my feelings for you were more than platonic friendship. I found myself thinking about you more than I cared to admit, wondering if you were waiting for me to come back or if you had already moved on."
He stopped again, contemplating his next words. "I am so fortunate to have found you, Molly Hooper. You are my complementary DNA strand, designed just for me." He reached into his suit pocket and retrieved a small black box. "Will you do me the honor of becoming my wife?"
The tears were falling freely now, as she gaped at the man she loved. Only Sherlock could turn molecular biology into a marriage proposal. Without replying, she wrapped her arms around his neck and dragged him down to press her mouth to his. She kissed him furiously, tasting the salt of her tears on his lips. She felt him grip her waist, wanting to bring her as close as humanly possible.
She finally pulled away, barely a millimeter separating their faces, and looked at him. "I love you." She said it simply. It was the only possible answer. He beamed at her, his expression the happiest she had ever seen. He opened the box (she had forgotten about the ring in her excitement) and drew out an exquisite gold band, with a simple sapphire adorning it, flanked by two diamonds on either side.
"Do you like it? It was my mother's."
Her hands flew to her mouth as she gazed at her fiancé. "Sherlock! It's beautiful!" He slid it on her left ring finger, flinging the box over his shoulder before grinning and kissing her once more.
John Watson awoke to the sound of a small ping coming from the mobile phone on his bedside table. Mary watched as he read the message and laughed in amusement before tapping him on the shoulder. "What is it?"
"It worked. His ridiculous speech worked! I guess those two really are made for each other…." John shook his head in bewilderment and set his phone back on the table. "It looks like we have another wedding to plan." He kissed his wife's smiling mouth and curled back under the sheets.
I could just see John's reaction to Sherlock's proposal, so I had to add that last little scene at the end. On a side note, if I convince a guy to propose to me, I might be just a little disappointed if it doesn't happen like this. ;) Please leave a review and let me know what you thought!
