s4 is going to be dark = sherlock is blind speculation
remember when they told us it was going to be dark?
remember when one of our speculations was that “dark” meant blindness as in sherlock going blind because of culverton
we may have been wrong but damn it that headcanon still haunts me to this very day
and i still NEED to see it at least fic’d!! oh all the angst can you imagine when sherlock was hospitalized after john beat him up and culverton went into his room, what if culverton had put something into his iv drip that ended up blinding sherlock
can you imagine when sherlock eventually wakes up and he discovers he cant see and he panics, he can feel someone’s presence there and assumed its john and he pleads and pleads “john what’s happening to me? why cant i see? john–!” and tears rolled down as panic and defeat overwhelms him. His arms searching for john but when he finally touched the other person, only then did he realize it wasnt john. The arm was too thick, too hairy. Not john then who? and culverton finally cracks up. “Oh you’re not so brilliant when you cant observe anything are you? no more deductions, no more tricks, no more plans. Can’t get yourself out of this mess this time…”
and what if, even after john comes in to save him from culverton, sherlock pleads to him “John please, get me something, i suspect he must’ve given me something to make me blind. I-I can’t see! Please just, undo what he did, you’re a doctor, get me something that will undo this thing”
but it turns out that there was nothing john could do, nothing anyone could do. the damage was permanent, and sherlock had to live the rest of his life unable to see john smile at him anymore. His final vision of john was John staring at him with disdain. His last vision of the man he loves most was the look of utter fury and disgust. And now he can never see john again. He’ll never see how Rosie will look as she grows up. He’ll never be able to observe and deduce like he used to. He can’t learn a music sheet and play it like he used to.
