Summary: The Doctor's habit of getting involved with local problems backfires.
“Perhaps I can be of assistance.”
That was how a lot of the Doctor’s adventures seemed to begin; he’d find himself on a planet, or a space station, sometimes a spaceship, there’d be a problem of some kind, and unable to resist meddling in other people’s business, he’d find himself offering to help. Well, what was the point of being able to travel through space and time if he didn’t lend a hand where it was needed?
Usually it worked out better than this though.
“Thrown in jail for interfering!” Martha was understandably upset.
