This is an article about the 10th series of Doctor Who. Having spent 24 years on Darillium with River Song, the Doctor is back to face one of his most dangerous adversaries yet. This series focuses on the Minister for War mentioned in the Series 9 two parter Under the Lake/Before the Flood. This series also introduces us to new companion Holly Taylor, a biologist who lost her father during the Battle of Canary Wharf, before also losing her brother during the events of the Dalek Invasion of Earth in 2009. She has a great hatred of the Daleks, and resents aliens as a whole before meeting the Doctor, who shows her that there is far more out in the Universe than beings who wish to conquer and destroy.
