"He’s not a sociopath, nor is he high-functioning. He’d really like to be a sociopath. But he’s so fucking not. The wonderful drama of Sherlock Holmes is that he’s aspiring to this extraordinary standard. He is at root an absolutely ordinary man with a very, very big brain. He’s repressed his emotions, his passions, his desires, in order to make his brain work better — in itself, a very emotional decision, and it does suggest that he must be very emotional if he thinks emotions get in the way. I just think Sherlock Holmes must be bursting!"

Oh this is great
