Since its beginning a few years ago, 'Game of Thrones' has established itself as a TV drama where no one was safe. It was the sudden and unexpected death of Eddard (Ned) Stark that went on fueling the idea of insecurity over all characters. When it comes to Jon Snow and his evolution throughout the seasons, he turned from an apparently outcasted character into a central pillar of the entire narrative.

As seasons went by one after another, the spectrum of death improved partially only to get a serious blow at the end of Season 5 when Jon Snow's death sent shockwaves through the entire audience.

It came in a moment when theoretically the Stark's bastard seemed out of reach as the Black Castle's Lord Commander. The plot that cost Jon his own life was an ingenious way to seal the deal regarding the fifth season.

Ressurection and meeting with the White Walkers

By the hand of the Red Priest Melisandre's witchcraft and obscure rituals, Jon Snow was given a second chance (life) when the Season 6 emerged. Since then, he has been at the center of some of the highlights of the entire TV drama to date. He made an improbable alliance with people from behind the Wall; he went on fighting against the White Walkers in the Battle of Hardhome.

Moreover, he emerged as the real leader of Winterfell and by extension the entire territory of Westeros' North side.

Trying to acquire a strong united army to fight against the death army, Snow makes the first steps in what may end up being a strong alliance between the North and the rightful heir to the Iron Throne. Daenerys Targaryen and Jon Snow would make it to the top of the list of most pleasant alliances ever. Some see their relationship developing into a new phase as they may even get married to one another.

Jon Snow may owe a debt to Lord of the Light

Melisandre brought Jn SNow to life by appealing to the almighty Lord of the Light, the higher power she believes in. As the ritual turned out to be successful, Jon Snow came back from the dead in the early stages of Season 6. Since then, he has only accumulated power and influence.

But, there might a trick into the whole story of his resurrection.

The Lord of the Light may want something in return at some point, Jon Snow's own life or anything else. There are a lot of possibilities marching on this theory. So, Jon SNow, perhaps the most beloved character from 'Game of Thrones', could end up being an exchange coin in a dark, celestial trade off.
