10 Most Shocking Moments In Game Of Thrones Season Finales

2. Cersei’s Madness (Season Six)

Any sympathy directed towards Cersei following the climax of season five disappeared soon into series six as she quickly reminded us of the evil tyrant she had always been.

Incensed by the Dornish murder of her daughter Myrcella, and King Tommen - her only living child - turning against her to side with the faith militant that shamed her, Cersei’s transformation into the Mad Queen was complete by episode ten - The Winds of Winter.

Cersei sent her conscience Jaime off to the Riverlands while she plotted with the dastardly Qyburn to destroy her enemies, even taking inspiration from the Mad King’s obsession with Wildfire.

The series six finale went off with a bang as she blew up the Sept of Baelor, and inside it the High Sparrow and his servants, as well as Marjory and Loras Tyrell. Tommen was spared the emerald explosion, but did commit suicide; merely collateral damage to his mother.
