As any other significant TV show, 'Game of Thrones' has its villains and its own heroes. By far one of the most intriguing characters of the series, Jon Snow (Kit Harington) had a steady rise throughout the past seven seasons. Starting as a background persona with no solid projection for the future, the one who went as Ned Stark's spoils of war for quite some time, he has become the central point of the entire story. Given the way Season 7 ended, it appears that his role would be even bigger during Season 8. Some Targaryen roots place him at the core of the Iron Throne's claim and the only capable to lead Westeros in its battle for survival.
Jon Snow amassed so much power in his hands
It's been a journey since Jon Snow was just a seemingly unknown character in Winterfell. Now, he goes by as the King in the North and the freshly forget alliance with Daenerys Targaryen has just added some extra points on his side of the balance. Moreover, Season 7 ended with Bran discussing with Tarly about the delicate situation of Jon Snow. A Targaryen himself, he might hamper Daenerys' claim to the Iron Throne. The current arrangement between Jon and Daenerys might have serious future implications. As we all saw, Daenerys has a dangerous sense of entitlement when it comes to holding power in her hands.
Basically, even without knowing it, Jon and Daenerys are both entitled to claim the Iron Throne.
In the meantime, the Army of the dead is marching down from the North threatening to bring total destruction in the Realm.
Jon Snow and his special connection with death
Jon Snow has an intriguing relationship with death. That became obvious especially after Season 5 ended. As a result of a plot of some Night's Watch members, Snow, who was the lord commandant at the time, was murdered.
That outcome came as a shock for everyone, but he got a second a chance with help from the Red Priest Melisandre.
The Season 7 final had Jon Snow in the middle of another near-death experience. Either hypothermia or the Army of the dead was about to kill him off for a second time. An unexpected rescuer emerged as Benjen Stark sacrificed himself to save the King in the North.
Season 8 will write down the last 'Game of Thrones' chapter and given his history, Jon Snow might not be alive when the dust will settle down. He is the most valuable target for both Cersei Lannister and the Night King. Let's not forget that the brave character has a tendency to throw himself where the greatest danger resides.
