Sherlock stood shakily upright in the kitchen, a steadying hand on the table. His head was tipped backwards, and he dabbed at his bloody nose with a tissue.

Downstairs, the front door slammed loudly shut. He could practically hear John storming down the street away from 221B.

"I don't understand," Sherlock told Charlene thickly. "I apologised, isn't that what I was supposed to do?"

She shook her head at him, leaning against the sink. "You really don't know anything about human nature, do you?"

"Nature…no," he told her. "Human…no."

"Well, I'd better teach you then," she said lightly.

Sherlock squinted at her sideways. "You're not…angry at me?" he asked curiously. "Annoyed?"

She smiled sadly. "Well, for one, that'd be hypocritical." Her brother smiled faintly. "If I am angry at you, it's only because of what you put John through."

Sherlock lowered his head to look at her. He thought about it, then nodded. "Fair enough."

"I'll talk him round. Don't worry."

"I'm not worried."

"No, you're not." Charlene paused, then she grinned. "Hello, Sherlock. Nice to meet you at last."

He carefully returned her smile. "Hello, Charlene."
