This was the most moving part of the entire episode if you ask me. I think this is where Sherlock realizes how strongly John believes in him. Remember when he was surprised that John didn’t suggest he was the murderer when he had the pink suitcase? He probably took it as naivety. Then he tried to convince him that he’s not someone to look up to as a hero in TGG. And even in Reichenbach he didn’t understand why John didn’t believe the theory that he may be a fraud. He said he just didn’t want to admit that he was misled. But here, look at him here.. He seems so touched. He’s so happy he breaks character. Sherlock. The master of disguise, in a situation where it’s so important to convince John that he’s telling the truth.
Just imagine spending your whole life alone and misunderstood, hated and envied by everyone around you, and then someone turns up who shows this kind of admiration and respect for you.
no. No. NO.
may I add that the use of words ” you could ” makes it all even worse? Past tense. John knew what was going to happen next and with “you could” he’s trying to bring the dead man back to life. Show him that there were people who believed in him, John believed in him. Stop him from taking that step. Or perhaps just reassuring him before the other man has taken his deathly step. Or perhaps saying that he loved Sherlock. He was the only one who could.
