[Note: This is a Romanian language interview, but can be translated with Google or other services.]
La Garde de Nuit at Worldcon, and sat down for an interview with them. But they managed to have a contingent at the London Waterstones event, and arranged a brief sit down with George afterward. Not only is their event report the most detailed they've seen, they also had some fun moments with George afterwards.]
I was at the talk, and the whole question was that the interviewer asked him which dragon he would ride and which sword he would want to wield. He actually paused for quite a while before answering the question (probably the longest of any of the questions he was asked). For the dragon answer, his tone was kinda jokey and he went with Balerion the Black Dread, saying if he could ride a dragon he'd go with the biggest one who remembered Valyria. For the sword question, he definitely used a more serious tone, and at the "who knows what magical properties a falling star has" point, it definitely sounded like he was dropping a hint.
