Mark Gatiss said recently that both Sherlock and Mycroft are capable of emotion, but Sherlock is more tempted to give in to the temptation of it than Mycroft is. I was a little surpised by that at first, because if anyone is an honest-to-god “high functioning sociopath” it’s Mycroft. Generally I prefer not to take a lead from creators and writers when they’re talking outside the text itself (given that we’re in a fandom that where the creators/writers lie like the most beautiful lying liars). I’d rather take the text alone as evidence and go from there. I love the idea of Sherlock being an ordinary man pretending to be otherwise, but Mycroft? An ordinary man? I wasn’t sure at first, but I’ve come around to Gatiss’ idea. Now I dig it.
