I'm back! Here's the next the chapter. Enjoy!

Disclaimer: I wished I owned Sherlock, but I don't.

Warning: It gets a bit deep.

Sherlock spent the rest of the day going through the tow-inch stack of papers. He would read something, then either go on the Internet, or disappear to another part of the flat. Once he ripped the sheet he had been reading in half. Kailey was impressed at his work ethic.

John had explained what might happen now that Sherlock was on a case, and even gave her permission to use Sherlock's room if he disturbed her sleep.

That night, John brought home pizza for dinner to "celebrate Kailey's first night" with them. He cleaved the kitchen table of Sherlock's chemistry set, sterilized the surface, and set the table. After finding something safe to drink, he managed to get Sherlock to come sit with them, since he said he wasn't hungry.

"So," John said, cutting his slice with a fork and knife. "You're not from here, are you?"

"No."

Kailey looked at Sherlock when he answered with her.

"She's from America," Sherlock observed. "California, from her accent."

Kailey rolled her eyes. "Yes, I'm from Cali. Anything else?"

"Wait," said John. "If you're from California, what were you doing in a foster home?"

Sherlock opened his mouth, but shut it when Kailey gave him a glowering look. This was something she had to do herself.

"My family was murdered in May of last year. The police tried to find the killer, but it turned cold due to "a lack of evidence." A few weeks later, the house was blown up; the police thought it was caused by a gas leak, but I think it was rigged.

"I was sent here to live with my cousin, who had some addiction problems. After she was arrested, Child Welfare Services put me into foster care. I've been there ever since."

There was a slight pause at the table.

"Sorry." John said.

Kailey shrugged. "It's cool. I've come to terms with it. Being away I think helped."

"What did your dad do?"

"He was an agent. For movie stars? He was pretty good at his job."

"Mmm." John swallowed his food. "Sherlock, take a piece. It's really good."

"No."

"But don't you need energy from food?" Kailey asked, looking quizzically between the pizza and the detective.

Sherlock paused. "Touché."

He didn't touch the pizza slice.

Kailey grabbed it and bit, the cheese being reduced to greasy strings. She dropped it on her plate.

"I'm just glad they haven't found our place in Rio."

"What?" John asked.

"My family has a house in Rio. We keep the deed in our gardener's name, since his last name is pretty common."

"Rio." Sherlock breathed.

"Pardon?"

"Nothing." Sherlock cleared his throat. "You go to school?"

Kailey nodded. "Churchill Academy. I usually take the subway, but I need to renew my pass."

"Tube."

Kailey looked at him. "What is it with you and random words?"

"By subway, you mean tube."

"You know what I mean."

Sherlock allowed himself a taut smile at her reaction. "No, I don't."

"Shut up!" Kailey said, smacking him twice on the forearm. "You know exactly what I mean!"

"Alright, alright!" John said. "If you two are going to fight, I'm going to have to switch the sleeping arrangements around."

"We're not fighting. We are having a physical discussion."

John smirked. "Whatever you call it, make it stop."

Kailey finished her drink. "I'm done anyway." She collected her dishes. "Thanks for the pizza."

"You're welcome."

Kailey placed her stuff in the sink and headed into the living room.

"See? It's working out fine." John said quietly to Sherlock.

He said nothing. Instead, he got up and left the room.
