Nothing is mine.
Greg quietly watched Sherlock's transformation from being completely insufferable to being mildly insufferable. This was all due to John, the quietly unassuming, seemingly ordinary former army doctor, recently and honorably discharged.
John could easily transform himself as well. Greg knew damn well who shot Jeff Hope that first night. But he chose to look the other way. As time went on the more Greg Lestrade looked the other way.
It all came to a head with Sherlock's supposed suicide. He proved to them - all of them - just how far Sherlock would go to protect those he cared for.
Thank you for reading.
