Returning from dead changes Jon Snow: Kit Harington

Actor Kit Harington has revealed that his part's resurrection in the beginning of the season six is going to change the character.
The fan favourite character was stabbed to death in the fifth season finale, only to be resurrected in the second episode of the latest season by Melisandre.
"There's a brilliant line when Melisandre asks: 'What did you see?' And he says: 'Nothing, there was nothing at all.' That cuts right to our deepest fear, that there's nothing after death. And that's the most important line in the whole season for me," Harington told the Entertainment Weekly.
"Jon's never been afraid of death, and that's made him a strong and honorable person. He realizes something about his life now: He has to live it, because that's all there is. He's been over the line and there's nothing there. And that changes him. It literally puts the fear of god into him.

"He's seen oblivion and that's got to change somebody in the most fundamental way there is. He doesn't want to die ever again. But if he does, he doesn't want to be brought back.
