Can we just appreciate how in sync John and Sherlock are? The other moment I like is at the beginning of Hounds when the doorbell rings and both of them shout “Client!” Together. So I admit that BBC’s Watson isn’t as perceptive as Elementary’s, but he is catching on to some key things. What’s nice about the distinction is that in the BBC version you have John accepting Sherlock pretty much wholeheartedly. He gets that Sherlock is a difficult man, but he doesn’t mind. In Elementary you get Joan who refuses to let Sherlock retreat into himself and repress his weaknesses. In either case the duo makes a lovely team. And no matter how you slice it, John and Joan are the heart while both Sherlocks are the brains. You can’t have one without the other.
