Isn't it obvious that the answer is 'I got it wrong' - do people really need something so obvious discussing in any detail?
No, I don't think anyone needs that, nor did I see anyone saying so. I was just a little surprised about the seemingly-angry response to Christopher's question, that's all! No biggie.
Moriarty would indeed be an interesting followup. I'd love to see his reaction to his "incarceration."
