<P> This is obviously a big deal, the death of Jon Snow . This is something we've been thinking about for a long long time, and Alliser kills him, it's kind of like, it's a bad guy killing a good guy . But when it's Olly holding the knife...Olly's not a bad guy . Olly's a kid who's seen just way too much horror way too early, and he makes a decision that's a really hard decision for him but you understand where he's coming from...It's one of those great conflicts that makes us love the books and this saga, is that it's, ultimately it's not just about good vs evil, it's about people of good intentions who come into conflict with each other because they have very different views of the world, and unfortunately it did not work out well for Jon Snow in this case . </P> <P> Writing for The New York Times, Jeremy Egner called Jon's demise "the biggest death on the show" since Ned Stark's beheading in season 1 . Amid strong fan reaction over Jon's death on social media, immediately following the episode journalists began theorizing how the show could resurrect the character . Nate Jones of Vulture.com noted: </P> <P> It's easy to see what (other characters') deaths meant for the series' sprawling narrative: Ned's execution sent the Stark kids adrift in a universe where there was nobody looking out for them, while Robb's murder was the final death knell for the hopes that the saga would ever have a traditional' happy' ending . What would be accomplished, narratively, by getting rid of Jon permanently right now? </P> <P> A July 2015 sighting of Harington arriving in Belfast, a primary filming location for the series where other actors were arriving for season 6 script read - throughs, prompted further speculation about the character's return . However, a story in Vanity Fair pointed out that Charles Dance had been seen in Belfast the previous year after his character Tywin Lannister's death as well, and he only appeared in the first episode of the subsequent season as a corpse . Another photo that showed Harington on set in Belfast in a costume that varied from the Night's Watch outfit was published on September 25, 2015 . A season 6 Game of Thrones promotional poster released in November 2015 featured a bloodied Jon . </P>
