"You're Sherlock Holmes?" the man asked grinning largely. When the boy nodded nine spun around shouting "Fantastic!" causing Rose to jump.

"Wait a minuet, who's Sherlock Holmes?" Rose asked looking between the Doctor and the dark haired kid.

Ignoring her, the Doctor turned suddenly back to Sherlock. "You look a lot different as a kid. Not nearly as tall as last time I saw you."

"I've never met you before." Sherlock said confidently.

"And you would know." Nine said seriously. He wasn't being sarcastic, it was the truth. Sherlock would definitely be a person to remember the Doctor.

"Hold on," Rose said before the Doctor started into a rant. "Who's Sherlock Holmes?"

"I am."

"He is." The Doctor and Sherlock spoke at once.

Before Rose got a chance to explain, the room shook lurching everyone to the floor.
