Game of Thrones script reveals Drogon's motivation for burning Iron Throne

The script for the last ever Game of Thrones episode reveals why Daenerys' dragon burnt down the Iron Throne.

Drogon melted the chair after discovering his mother Daenerys dead, stabbed by her lover/nephew Jon Snow.

Fans of the show suggested two theories for why he attacked the throne - either he was super-smart and understood the symbolism of the throne in his mother's mental breakdown, or he saw the stab wound and decided to hurt the chair made of swords.

Turns out it's neither. According to the Emmy-nominated script, released in the run-up to the awards, Drogon simply wanted to watch the world burn.

"Drogon wants to burn the world but he will not kill Jon," the script says.

"He breathes fire on the back wall, blasting down what remains of the great red blocks of stone.

"We look over Jon's shoulder as the fire sweeps toward the throne - not the target of Drogon's wrath, just a dumb bystander caught up in the conflagration." 

Game of Thrones scored 137 Emmy nominations, including outstanding drama series, outstanding writing for a drama series and outstanding directing for a drama series.

But many fans of the show weren't happy with the final season and have started a petition for the show to be remade "with competent writers".

Season eight cost $90 million to make, the most expensive of any of the show's seasons, so it's unlikely to be redone, although there are prequels in the works.
