This panel discussion
revolves mainly around the Game of Thrones
HBO series, and it was recorded around the time of the most recent Emmy awards. However, there's a very nice exchange with the two show runners, David Benioff and D.B. Weiss regarding their first meeting with author George R.R. Martin and the possible adaptation of his series of novels. It was reportedly a very LONG meeting, and one of the questions that Martin posed to the two prospective show runners?
"Who is Jon Snow's mother?"
Without a doubt this is one of the more significant mysteries of both the novels and the show. But I suspect we may have to wait until The Winds of Winter
is finally released to see if this mystery gets resolved.
Be that as it may, apparently Martin was impressed with Benioff and Weiss, because they guessed correctly.
