Author's Note: This story takes place through most of the series and partially before and after, assuming that Moriarty is still alive from the teaser at the end of season 3. There will be many flashback scenes. Also, I am currently writing multiple stories, so I am warning you now that I may not be able to update as often as I would like. Now, on with the story!

Lily Eileen Moriarty woke in the morning to a yet another dreadful stomachache. She thought that by her fourth month, she would've gotten used to the morning sickness, but she was sadly mistaken. Her husband James ("Jamie" as she called him) looked at her sympathetically.

"I can't wait to get out of London," she said, "As much as I love it, I think I need to be away from the city air."

"Don't you worry, love, we're going to find the best home for you, and the baby," he said.

"Won't it be nice to finally settle down, and just focus on raising our family?"

"Yes. I think that will be all the distraction I'll need," he smiled and kissed her on the cheek.

The couple enjoyed their relaxing Sunday morning by looking at houses for sail in the countryside. Jamie took on the difficult task of fixing breakfast for Lily. Yesterday, she had been craving eggs all day, scrambled to just the right texture. The morning before that, she had wanted to nothing but fruit juice since her stomach was acting up. Not long after she had woken up today, she said she was craving sausages, but when they had begun to cook, the smell of them made her sick. Now she said she wanted toast with strawberry jam. Jamie simply nodded every time she changed her mind and asked for different food. He had no problem doing anything to make her more comfortable.

"Just think, only five more months of putting up with me, and then we both get to stay up all night with a crying baby," she joked.

"Like I said, 'All the distraction I'll need.'" He wrapped his arms around her and played with her short, blond hair.

Later in the day, Lily said, "We're expecting company."

"Oh?" Jamie sipped the tea his wife had made.

"Let's just say I have a little surprise."

At exactly twelve o'clock, the front door opened with their visitor coming inside. He found his way to the sitting room, where Jamie nearly dropped his teacup when he saw the visitor's face.

"Well let's get started already. I'm taking time out of a serial killer case, so this had better be worthwhile," said Sherlock, taking off his scarf and coat.

"Sherlock! What the Hell are you doing here?" asked Jamie furiously.

"Calm down, darling. I invited him," said Lily.

"You what?" asked Jamie in astonishment.

"Oh don't make the woman repeat herself. Now shut up, so we can start talking so I can leave sooner." Sherlock turned to Lily, "You said it was just going to be you and me."

"It will be, in just a moment," she said. "I'm sorry," she told Jamie.

"Sorry for..." he began to say. Then he blinked a couple of times and he realized. He looked at Sherlock, then at his tea, then back at Lily. "Oh Lily," he said before falling into her lap.

"Drugging the tea, clever," said Sherlock. He pulled up a chair and sat. "Now let's not waste any time, any of my time, that is."

"I want to tell you a story, my story and my husband's story. I need your help."

"Go on."

"I'm having a baby."

"I know."

"Of course you do. No need to explain how. Jamie and I are settling down to have a family. With our pasts, our child's chances of having a normal life are slim to none, but that doesn't mean the baby will have an unhappy life. To make sure our child will be safe, Jamie and I need to be there for him, or her. We don't know yet."

"And how is that my responsibility?"

"Well, just listen and find out."
