Sherlock had been looking through the house several weeks after they had moved in. He had noticed several empty bedrooms, and was confused. The house was quiet. Lily and Callum were at school, Calvin had gone home (and most likely to school) and Jonah was at school. Sherlock went into one of the many empty rooms, and looked out the window. Sherlock was surprised to find that his brother had called in favors to people, and they were now mowing the lawn, gardening, cleaning the pool, and Mrs. Hudson, who was also to move in with them, was downstairs, reading. Molly came in behind Sherlock. He turned to look at her, noting that she hid something behind her back.
"I don't understand why we have so many empty bedrooms." Sherlock said. "What would we use this room for?" Molly bit her lip, hiding her obvious excitement.
"What about, I don't know, a nursery?" Sherlock looked at her in surprise.
"A nursery? What for?" She handed him a long white stick.
"I'm pregnant." That was certainly faster than they had anticipated. Sherlock looked up from the little plus sign, to back at Molly, his blue eyes huge. Molly giggled, her hand over her mouth, trying not to cry. His face split, from being in shock, to a huge grin.
"Molly, are you serious?" She nodded, a few tears running down her face. He held her arms out, and she ran into them. Molly cried while they hugged.
"Molly, that's brilliant." Sherlock said. "We have to find a clever way to tell Jonah."
"All right." She said. "Mrs. Hudson knows. She was helping me figure out whether or not we were right." They held onto each other, laughing. Finally, Sherlock leaned in, and crushed his mouth to hers. They kissed, until a confused voice said, "Dad?" Sherlock broke the kiss, and looked at Jonah.
"I'm just really excited!" Molly said, "Tell him." Jonah looked surprised.
"Daddy, tell me what?" He looked up into Sherlock's eyes.
"Molly adopted you, for starters." His whole face lit up.
"You did?" He shouted, running to her, and hugging her. "Thank you!"
"Of course, honey." Molly said. He was grinning. "But I have news too...I'm having a baby." Jonah's eyes went wide.
"Really?" He asked. Sherlock was struck by how much like Lestrade Jonah resembled when he did that. He smirked.
"Yes, son, and you must keep it a secret. We have to go to the doctors to be completely certain." Sherlock said. Jonah ran, and hugged Sherlock.
"You mean I could have a brother or sister?" Sherlock nodded. He held on tight. Sherlock scooped the small eight-year-old up, and stood to full height, reaching out to Molly, who joined their hug.
Several hours later, Mrs. Hudson, who came to announce dinner, finally found them in one big embrace, laughing, Molly crying, and Jonah hyper as can be.
She left them be
The next morning, Sherlock and Molly went into the clinic, where Molly had an appointment. Fortunately, it was Sherlock's day off, and Molly's day to work later. They were called in immediately, being the first ones in. Sherlock and Molly went into the room, and Molly's weight and height were all checked. She sat on the table, and held Sherlock's hand. The doctor ran all of the necessary tests, and, while the results printed, the doctor sat down with a pen, her file, and a clip board, ready for some questioning. After that, the doctor went to get the results. Sherlock and Molly were alone.
"Well, what do you think?" Sherlock asked. She was nervous, and only shrugged. "I'm almost certain." His deduction techniques were the same, if not stronger, but he hadn't noticed Molly's pregnancy. He wasn't sure if he was just not seeing the changes in his wife, or if they were too subtle for even his eyes. The doctor came in then.
"Congratulations, Detective Inspector and Doctor Holmes." He said, smiling. "You're a month pregnant."
