Epilogue
The man in front of him was a soldier, he holds himself proud and ready, he withstands Mycroft without blinking with an eye. It took him a long second to understand what he was seeing. Mycroft was used to the blue numbers floating above the head of people. But this number he was used to, he saw it every day above Sherlock's head. The beautiful number that told him his brother had left enough time to grow old and now he know that he wouldn't be alone.
John Watson would stand by his side until the day they both would die at the same moment and if he had his mother's gift he would be able to tell that they were together. His brother wouldn't be alone.
