Question: In doctor who, rose gets trapped in a parallel universe couldn't the doctor go back in time and change that!?
Answers:
He could!. However, the law of the Time Lords expressly forbids time lords from doing that!. Yes, the Doctor has done it before, but he hasn't been comfortable doing it!.Www@Enter-QA@Com
The Doctor tries to avoid crossing his own timeline!. Doing so can cause major problems, like in the episode Father's Day, when Rose saved her father from being hit by a car!.Www@Enter-QA@Com
I don't know much about Dr Who, but if Rose is either Billie Piper or (worse) Catherine Tate - I'd leave them trappedWww@Enter-QA@Com
