"Game of Thrones" season 5 episode 10, which will air this Sunday, is expected to be much bigger than the previous episodes, and speculation on who will bite the dust has been gaining momentum with each passing day.

One of the characters whose fate is in jeopardy is Kit Harington's Jon Snow, who gets stabbed by his comrades in the Night's Watch in George R R Martin's "A Dance with Dragons." And if Harington is to be believed, then no one is safe in the finale, including Jon.

However, there are a number of fan theories that hint that Jon could be one of the few people to survive. One theory states that although Jon will be shown as dead in the finale, season 6 could be the story of his resurrection. Speculations based on the events in "A Dance with Dragons" state that either the Red Priestess could play a part in bringing Jon back to life, or Jon would warg into his direwolf Ghost before his body stops functioning.

But one theory that has been gaining popularity is about Jon joining the White Walkers and ultimately leading them in a battle against Daenerys. According to what fans believe, Jon and Daenerys, both Targaryens as per L+R=J theory, will be on the opposite sides in the end, and their confrontation will mirror the Blackfyre Rebellion.

It remains to be seen if any of these theories turn out to be true, but one thing Harington can promise is that "Game of Thrones" season 5 finale will be huge.

According to the actor, Sunday's episode "The Dance of Dragons" and the season finale "Mother's Mercy," are going to make "Hardhome" seem like "Dr. Quinn, Medicine Woman" in comparison.

"It's going to be big," Harington told MTV News last week. "Those are two big episodes. If you thought last week's was fun, I believe — I haven't seen it; it doesn't include my story so much — that this week's is equally big. And then the last one is huge as well."

"I think this latest season has differed quite radically from the books in many ways," he said. "It's got up to a point in the books where I didn't read the fifth book, so I can't really speak about the differences between the two. I just know what I read at the start of the season, and this season was thrilling for many reasons, both what you've seen and coming up. It's incredible."

"Game of Thrones" season 5 finale will air on 14 June.
