In the morning, John came to pick Sherly up, instead of Mary. She had passed out on the couch, as it was finally quiet in the house. John figured that being ten minutes late to work would be okay. He knocked on the door before letting himself in.
"Mrs. Hudson? Sherlock?" he called before shutting the door. He climbed the steps and walked into the living room, where Sherlock was sleeping on the couch with Sherly in his chair. Slowly, she woke and smiled, seeing her dad. John picked her up and poked Sherlock awake. "Sherlock."
"What?" he whispered, jumping awake. He looked around the room, finding John next to him, a bit peeved. "Oh, hello, John."
"Wake up," he whispered as Sherly giggled.
"Mahde," she laughed, pointing at Sherlock, who smiled sleepily. John pursed his lips and looked out the window for a second.
"Sherlock, what did my baby girl say?" he whispered as Sherlock sat up, very pleased with himself. "Sherlock."
"Mahda," she exclaimed, throwing her arms in the air.
"You spent all night teaching my kid how to say murder?" John mumbled, beyond upset. Sherlock stood and straightened his shirt.
"Well, I am working a murder case, and she needed to learn the word some day," Sherlock reasoned as John put his hand on his brow.
"Mahda!" Sherly giggled loudly again.
"Sherlock," John whispered as he smiled. "Why?"
"You didn't ask me if I could look after her, so I didn't ask you what her first word would be," Sherlock explained as John took a deep breath.
"You can be so childish sometimes!" John hissed as Sherlock grinned.
"Well, then that makes three of us," he whispered as Sherly repeated her first word a few more times.
