The Doctor: The Fourth Great and Bountiful Human Empire. And there it is: planet Earth at its height. Covered with megacities, five moons, population 96 billion. The hub of a galactic domain, stretching across a million planets, a million species. With mankind right in the middle. [Adam faints] The Doctor: [leans towards Rose, still looking out over the Earth] He's your boyfriend.
