In the Season 6 finale, the explosives that Cersei Lannister has been talking about for years finally go off -- in spectacular fashion. She doesn't show up for her trial in the Great Sept of Baelor, because she's blowing it up. She kills two of her main enemies -- the High Sparrow and Margery Tyrell -- and positions herself to become the queen. Of course, she indirectly kills her son Tommen, who defenestrates himself rather than deal with the mess his mother has caused. You win some, you lose some. Shock rating: 5 hells!
