Next Week: The consequences of this simple action ensure that history follows its predicted path... Sometime: In the swirling maelstrom of the Time Vortex, The Council of Eight maps out every moment in history and take drastic measures to ensure it follows their predictions. But there is one elemental force that defies prediction, that fails to adhere to the laws of time and space... A rogue element that could destroy their plans merely by existing. Already events are mapped out and defined. Already the pieces of the trap are in place. The Council of Eight already knows when Sabbath will betray them. It knows when Fitz will survive the horrors in the Museum of Anthropology. It knows when Trix will come to his help. It knows when the Doctor will finally realize the truth. It knows that this will be: Never.
