26. The Ultimate Enemy
Premiere: April 30, 2005
To get some idea of the sheer horror and revulsion demonstrated by the Ninth Doctor (Chris Eccleston) in "Dalek," imagine that not only are you the last survivor of your race, but that you sacrificed your own people to destroy an enemy – and now a living representative of that enemy is displayed in chains before you. The enormity of the Doctor's guilt over his undisclosed actions in the universe-shredding Time War is telegraphed completely in his rage – a point not missed by his captive.
