Admittedly this is only a guess, particularly because HBO’s version has already deviated from the first book by making a big reveal about The Magisterium and Mrs. Coulter and pulling in bits from the second book in the series, The Subtle Knife. However, the only way to know for sure when Lee Scoresby will arrive on set is to bribe someone at HBO, relentlessly tweet at Miranda, who has been commenting on the show on Twitter, or just wait and watch. HBO can’t keep Hamilton fans waiting that much longer, right?
