Spoiler alert if you haven't yet watched last night's "Game of Thrones" episode. The reveal comes after months of speculation as to whether Snow would survive or whether Harington would continue on the series.
"If you want to help him, leave him be", she tells Davos when he asks for her help to bring back Jon.
In an interview with the Entertainment Weekly, he apologized to fans for lying about Snow's fate.
"I'm glad that people were upset that he died", he said. "I think my biggest fear was that people were not going to care or just be fine Jon Snow's dead".
Meanwhile, Harington teased that avid viewers should look forward to Snow's role in season 6 of the HBO show. He had no choice, and "no comment" wasn't exactly an option when they put him on the Season 6 press tour.
"Game of Thrones" dropped a very large plot twist Sunday night that many fans have been impatiently waiting for since the last finale.
The fact that Jon Snow was brought make in only the second episode of the season seems suspicious.
In April, weeks before the season six premiere on 24 April, Kit maintained his story and told United Kingdom chat show host Jonathan Ross that he was no longer involved in the show.
Harrington's character is one of the most popular on the Emmy Award winning show.
Carice van Houten, who plays Melisandre, gave Harington a cheeky new nickname based on "LC" during the incantation scene where she washes the blood from his naked body.
"Game of Thrones" airs on Sundays at 9 PM ET on HBO. In the novels, all the Stark children can warg-even if they don't know it. And in the books, Jon Snow whispers, "Ghost", just before he is stabbed for the final time.
