I think that John is like an airbag(in cars) between Sherlock and the world. He protects Sherlock from colliding with the entire human beings and cushions the impact when the crash happens. I’m sadly wondering how well Sherlock will be able to manage his life now - when he doesn’t have John with him. My heart aches for Sherlock.
You may think that I made this because his profile was too beautiful to resist. Hahaha, of course he’s beautiful but no, I made this because of the way his thumb moves. Quite sensual, isn’t it? …..Why are you looking at me like that?
