Re: We've been here before...
I'd have to watch it again but my impression was that it was the peace *negotiations* that had failed 15 times ? I.e. 15 times previously either Kate or Bonnie had pressed one or other of the buttons. Nothing happened (because the Osgood boxes are empty) but the Doctor had had to reset the scenario because the negotiations had failed, he hadn't managed to change their minds towards believing in/desiring peace.
