Yet when we asked Martin about his A Song of Ice and Fire saga, the author gave a very different answer. “Oh, you think he’s dead, do you?” Martin teased us in an interview in 2011. “My readers should know better than to take anything as gospel.”
And then just a few months ago when we re-asked about the topic, Martin told us: “If there’s one thing we know in A Song of Ice and Fire is that death is not necessarily permanent.”

"Jon fell to his knees. He found the dagger’s hilt and wrenched it free. In the cold night air the wound was smoking. 'Ghost,' he whispered. Pain washed over him. Stick them with the pointy end.

His long face floated before her, limned in tongues of red and orange, appearing and disappearing again, a shadow half- seen behind a fluttering curtain. Now he was a man, now a wolf, now a man again. But the skulls were here as well, the skulls were all around him.

Skulls. A thousand skulls, and the ####### boy again. Jon Snow...

Maybe Kit Harrington is done, but John Snow will live on in some form. Warging to Ghost, then back to a human form.

I know that many people who just watched the show are new to this argument and seem to think they know all the answers based off of one or two interviews, but this has been an on going debate going back to 2011 for many across the internet (and even further if we are talking strictly about him being the LoL). Do a little digging and you will see the stack of evidence.
