Heartbreaking Series 3 Storyline revealed in recent photo :’-(
Here we see Sherlock visiting John in the day room of the hospital where the good doctor has been recovering for the past month.
Unable to deal with Sherlock’s absence any longer, John Watson has gouged out his own eyes.
“I saw everything through Sherlock’s eyes,” he tells the unknown visitor. Once you’ve seen the world that way, ordinary sight will never be enough. There was no point in seeing anything anymore.“
Full of remorse, Sherlock confesses his identity (using his real voice), and vows to make it all up to John, if only John will let him.
"We can go back to Baker Street. We can go back to the way it was, John.”
“No, Sherlock. I would be no use to you. I’m broken. Damaged. I can’t see, for Christ’s sake!”
“You were broken and damaged when we first met. And you couldn’t see how important you were to the world. To my world. Come back with me, John. I will be your eyes, just as before.”
“And what will I be, Sherlock?”
“You will be my heart. As always.”
Sources speculate that later in the series, Mycroft will use his influence to enroll John in a top-secret, cutting-edge sight-restoration program sponsored by U.N.I.T. and led by the reclusive genius Doctor John Smith.
