Behind the Lens (слэш)

John's tumblr blog is becoming pretty popular when Sherlock stumbles across a "#johnlock" comment on his own rarely-frequented website.
He's not entirely impressed with John's explanation of "shipping," and he's definitely against the idea of his university flatmate starting a vlogging channel on YouTube.
But he grudgingly goes along with it, because the viewer count is rising quickly by the day, and because he's Sherlock, and he doesn't mind the attention.
It makes John happy too, but that kind of sentiment doesn't factor into Sherlock's actions whatsoever. Of course not.
