warning, possible spoilers
after the episode where the Dr. "dies" and after he says he's going to play things quieter (not introducing himself as "the doctor" anymore) my question is why would he care? he's a time traveller. you know "wibbly wobbly, timey whimy" sure he "died" but from everyone else's perspective he's pretty much everywhere anyways and they can't be sure if his "present self" is from before or after his death as no one but him can really track his regenerations for a reliable time line either. the only thing people know is that he was killed and they really can't do anything much anyways.
