"Game of Thrones" cast invaded San Diego Convention Center's Hall H on Friday, day two of Comic-Con 2015.

Season 5 finale Director David Nutter sat as panel, together with Maisie Williams (Arya Stark), Natalie Dormer (Margaery Tyrell), Gwendoline Christie (Brienne of Tarth), Sophie Turner (Sansa Stark), Alfie Allen (Theon Greyjoy) and Carice van Houten (Melisandre), to answer the inquiries of curious fans, according to a report by Ace Showbiz.

One of the topics was the death of Kit Harington's character, Jon Snow. In the season 5 finale, Snow's character was betrayed and murdered by his fellowmen from Night's Watch.

Many theories have since surfaced that he could've survived the attack. Some of the speculations stated that he may be dead now, but he won't remain dead forever.

Amidst the theories, Nutter insisted that he is dead. He had a quick recollection of his meeting with President Obama, who was asking for confirmation on the same concern.

"Mr. President, Jon Snow is deader than dead," he told the head of state.

"We couldn't wait for him to be gone, to be honest," Williams playfully said. "That hair, that face... so annoying."

Van Houten, who's playing the shadowbinder Melisandre, was asked if there is any magic that can bring Snow back from the dead. She said that she is in the dark, too.

It was an epic fail for those who are hoping that "Game of Thrones" Season 6 spoilers will be revealed during the Comic-Con 2015. Everyone in the panel seemed to be more reticent, according to Variety.

Executive producer Carolyn Strauss said it is getting harder with every season, adding that the production team really strives to maintain this element of surprise for the viewers.

People invest not just their time, but also emotions as they take part in each of the character's journey. Because of this, the writers put together the best and the most realistic storylines, Toronto Sun has learned.
