I'm sorry, if you were thinking that you would get a minute or two to decompress from last week's "Battle of the Bastards," you were very mistaken. On Sunday, Cersei used the wildfire on Game of Thrones that we all knew has been chillin' out under King's Landing. She decided that she would not be attending her trial and instead, she sent a message to the High Sparrow and Queen Margaery, and that message said, "Boom." In one of the biggest casualty moments in Game of Thrones, the Sept of the High Sparrow went up in green flames while Cersei watched safely from her window in the Red Keep.
See, Cersei allowed everyone to gather in the Sept for her trial.They went ahead and let Loras off with merely a seven-pointed star carved into his forehead and after those shenanigans, it was supposed to be Cersei's turn. Well, our Queen decided to send Zombie Mountain to stop Tommen from going to the Sept and set Qyburn's little birds on a mission to light the cache of wildfire off under the place where so many gathered, including The High Sparrow, Loras, Margaery and Mace Tyrell. Yup. When the wildfire went boom, they all went right along with it. Say goodbye to a handful of characters, friends. As sad as I am to see Margaery go (she had so much potential), the real tragedy was back in the Red Keep. Tommen watched the Sept explode from his own window and once he found out that his beloved queen had perished in the explosion, he took a leap from the tower to his death.
Cersei got what she wanted by she allowed Maggie The Frog's prophecy too come true in the process. All of her children died in golden shrouds. As badass as this was, things can't be good from here on out for her.
