Further complications [ edit source ]
Like with the
First and Second Doctor's timelines, tenuis issues are caused by the how the above dynamics are contradicted in secondary media.
For instance, several stories in prose and comics feature the Doctor, Sarah Jane, and
Harry Sullivan traveling together outside of their television adventures. However, excusing the many stories where the characters are trying to reach Scotland, there are no logical places in these stories where a gap could exist. One must presume, although it is speculatory, that Harry briefly rejoined the TARDIS team sometime after leaving.
Similarly, the comics featured in early issues of
feature the Doctor traveling alone with K9, and then later with Doctor Who Magazine Sharon Davies. Many presume that these take place before he met Romana, which is contradicted by references made to such things as the Black Guardian. Thus one has to presume that at some point, Romana II took a brief break from the TARDIS and rejoined the team later.
The Fourth Doctor has an advantage when dating his stories due to his costume. The Doctor started out with a short red blazer, a rainbow scarf, and tweed trousers. He soon switched to longer frock coats, in colors of grey, dark red, and dark brown. Eventually, his costume turned into the "red" version. This makes dating very simple when looking at how the Doctor is dressed.
