One of the main Stark protagonists who has yet to be killed off on Game of Thrones is Jon Snow, the bastard son of the late Ned Stark. Kit Harington, who portrays Snow, recently dished on his thoughts on the character.
Regarding the differences between the Jon Snow of the A Song of Ice and Fire novels and the Jon Snow of the show, Kit told the Wall Street Journal, “He’s becoming a young man in the books. He’s fourteen or fifteen, and a lot about his story is going into adulthood and becoming a man. I think that can get tough at times because you’re like ‘Why is this twenty six year old man acting in this way? He should have learned this by now.’ Actually it’s because in the books, he’s a much younger person… That can be tough at times.”
(It’s worth noting that the show has aged a number of the ASOIAF's younger characters; Daenerys and Robb Stark are also in their mid-teens in the books.)
Speaking of the books, Kit is no stranger to them, having read the first four out of a planned seven (and currently published five) in the series. He revealed, “I really like the books. I enjoy reading them. I find it useful. Some of the actors they want to take what they’re doing purely off the show because they do differ. But I like merging the two, so I like reading the books.” We see no harm in Kit reading the books, especially because, other than the age difference, Jon’s plot on the show does mirror the books more closely than the plots of many other characters.
One of the biggest plot developments for Jon has been his introduction to, and seduction by, the wildling Ygritte, played by Rose Leslie. Of their love scene in the cave, Kit told the Los Angeles Times, “It’s strange being nude in front of a whole crew full of people and trying to be very intimate. It’s a very surreal experience. But it was such a beautiful scene. It was one of those very happy moments that you get in this series. You don’t get many moments of tenderness.” Yes, this much we know!
Finally, Kit revealed what he knows about where his character might go from here. He told The Washington Post, “I don’t know who [Jon Snow's] mother is, I don’t know what is going to happen to him, I don’t know if he’s going to be in the sixth book. Not a clue.” Looks like Ygritte was right: You know nothing, Jon Snow.
