BBC Sherlock

What if it had been different? The main question lies in the sense of, what if things had gone differently? What if Mycroft and Sherlock never grew appart but closer? If maybe they found their goldfish and things weren't quite as harsh. If they had more time to fix things. If Mycroft didn't have to worry about how mutch longer he had left with his little brother. "Sherlock, Sherlock get up. Are you comming for breakfast or not? I have places to be you know."
