John took in everything that the two said, most of it getting only a cursory examination before being filed away for later. He was a bit surprised at Ianto's tone when he talked about Torchwood London, giving him a curious look as Jack explained the situation with Torchwood as an organization. "Don't worry," he said finally, "I doubt I'm going to have the time to investigate secret government organizations in Canary Wharf. And, so long as I don't mention it to Sherlock..."

He made a face, because he knew that he wouldn't have to say a damned thing to the other man. There'd be something in his posture or the way he blinked that gave him away, somehow. "Well, nobody will be doing any investigating what-so-ever. And I doubt I'll be going out to Cardiff any time soon." He paused, then said, "The... Cardiff from my world. This is a bit more difficult to talk about than I'd have thought."
