10 Doctor Who Characters Who Rejected The Doctor

The Doctor meets a hell of a lot of people while travelling the universe, some good, some bad, and some... a bit of both.

Because of this, the Doctor has to be incredibly selective when choosing individuals to become full-time TARDIS crew members, and while the correct decision isn't always made (cough Adam Mitchell cough), the Doctor has, for the most part, been sharing the TARDIS with some absolute gems, from 1963 to the present day.

But due to the constant amount of danger involved, journeying through time and space isn't for everyone, and over the years, quite a few characters have rejected the Doctor after being offered the chance to board the TARDIS.

We're not saying that these characters told the Doctor to 'eff off or anything, but for their own individual reasons, they all turned the Time Lord down, reluctant to live the life of an intergalactic adventurer. Whether it's a companion who doesn't want to carry on any longer, or a side character who refuses to transition to a more permanent position, not everyone is eager to travel the stars.

If you had to compile a small list of NuWho side characters who would make excellent full-time companions, then Osgood would almost certainly make the cut.

A UNIT scientist with a deep admiration for the Doctor, her intelligence would definitely come in handy when battling Daleks and space insects and sentient shadows, and plus - unlike so many of the Doctor's other companions - she would know exactly the sort of peril to expect if she were to live the TARDIS lifestyle.

Also, she dresses like the Doctor. That's an automatic win right there.

Sadly, Osgood did not become a full-time companion, but she was asked, with the Twelfth Doctor inviting her to join him at the end of Series 9's The Zygon Inversion. However, Osgood declined, reasoning that it was better for her to remain as a protector of Earth. Definitely the right call, considering how many deadly aliens just seem to gravitate towards our planet.
