Sherlock and Mycroft stood in the basement laboratory, the younger man explaining his advances in their work.

Mycroft however was watching his younger brother intently, his mind only half on what was being said.

"Don't." Sherlock said suddenly, staring at his brother through narrowed eyes.

Schooling his features to blank enquiry, Mycroft raised a shapely brow.

"You know exactly what I mean Mycroft! Don't deduce me, if you have a question then ask it."

"What's going on between you and the doctor? And please don't tell me nothing, I can see there is in the way that you look at him."

With a sigh Sherlock leaned against the workbench.

"He's my friend, Mycroft."

"Really? You'll forgive me if I find that hard to believe Sherlock, after all, you never even managed to make friends at school…"

"Nevertheless I have a friend now, one who would risk much to get me to safety when Barrymore would have killed me to bring you out of hiding." Suddenly all the fire seemed to have gone out of him as he added "And for all I knew, you didn't care."

"Sherlock!" Mycroft was horrified by his brother's words.

"I'm not a child now, I know my own mind." A slight smile graced his pale features. "For me, living with John has no limitations, no boundaries."
