So finally the Doctor ends up in a room with Hitler. The year is 1938. The Doctor or one his companions could kill Hitler. Imagine. You may think you’d never kill anyone, but would you kill Hitler in 1938?
Imagine Poland never invaded. America never liberating Paris. London never going through the Blitz. And millions of people living the whole of their lives.
What would the world be like today? How would Churchill be remembered? What would’ve happened in Russia? Would the Japanese have bombed Pearl Harbor?
How do you imagine the world would be different and where is this parallel universe?
And I want to add…um, Stephen Moffat? He’s writing (as in writing and/or in charge of) two, TWO, shows with iconic British characters. The Doctor and Sherlock Holmes. Imagine being responsible not just for your characters, but famous and indelible and amazing and loved characters. He’s right when he says it is insane. What am I complaining about?
