John and Sherlock have been through a lot together, even by the halfway point of Series 2. And though John vehemently denies that the pair of them are gay, they're no strangers to fighting like a married couple. One of the most marriage-like rows that the pair endure happens when Sherlock's frightened of the hound and questioning everything he believes to be true. John offers a hand to calm him down, but Sherlock refuses his help. "Now why would you listen to me. I'm just your friend," John snorts. "I don't have friends!" Sherlock says, haughtily. It's a totally avoidable argument, and one where that Sherlock's clearly in the wrong; taking a step back for a second to remember all the danger John gets himself into, just for his mate, would certainly cool proceedings down. They later make up when Sherlock tells him that he just has the one friend: good save. Still, there was no need be such an ass to John, was there? Sherlock would go on to lock him in the lab that episode; it was a tempestuous time for their friendship.
