The role of the companion in Doctor Who is to serve as an audience-insert. It is the companions job to ask questions that the Doctor will then answer.

The companions of the First Doctor were an interesting lot, and you should really get to know them. Let's not forget, they're the ones who started it all. The show's formative years introduced viewers to, amongst others, school teachers, a space pilot, a space cop, a swinging 60s girl, a royal navy sailor and, of course, the Doctor's very own granddaughter.
