the headcanon that ruined me
the ninth doctor had a northern accent, presumably because he wanted to change everything about himself after the time war
before regenerating, the last person he saw was Rose, who had a London accent
the tenth doctor had a London accent
probably a casting coincidence. BUT the last person Ten saw was Rose (again)
Eleven had that same London accent
well, maybe they just prefer actors with a London accent. BUT the last person Eleven saw was Amy (yes he glanced back at Clara but it was very brief)
And guess what freaking accent Twelve has.
Amy Pond's full blown, sassy Scottish one.
