Game Of Thrones Season 6 Finale: 12 Last Minute Rumours You Need To Know
10. Cersei Burns King's Landing

When it became clear that Cersei was facing a traditional trial before seven judges, she was surprisingly calm, thanks - no doubt - to the information Qyburn had confirmed for her. That secret rumour relates to the stash of Wildfire under King's Landing, which the "Mad Queen" will use against her own subjects to free her son from the tyranny of the Faith.
Cue massive carnage.
Evidence?
First off, Bran's vision showed off images of King's Landing burning in Wildfire, while the last episode saw a reminder from Tyrion that the material was stashed throughout the city, including under the Sept. And then there was Jaime's warning to Edmure Tully that she would "burn cities to Ash" for her children.
Even if she doesn't burn the whole city, it seems inevitable that she'll use the magical fire against the Sparrows.
