10 Doctor Who Characters Who Should Have Been Companions

10. Madame De Pompadour

It's very hard to choose what Steven Moffat's masterpiece is in the Doctor Who universe. Blink is a horror classic and his two-part stories from the Tennant era are brilliant. But an underrated gem is The Girl in The Fireplace. A fabulous time travel story that introduces audience to Madame De Pompadour, otherwise known as Reinette.

Reinette began the story as a scared child, fearful of the monsters under her bed. However, throughout the episode we see her grow and become a strong character who can hold her own without The Doctor's assistance. Sadly, Reinette meets a tragic end as The Doctor misses their final goodbye, and that ending leaves us wanting more of that relationship.

It is in this episode that we see a little bit more of The Doctor's past and it is actually Reinette who asks about his history. During a psychic link, she sees into his past and that leaves the door open for this to explored. The chemistry between David Tennant and Sophia Myles is phenomenal and would have made for a great duo post-Rose Tyler.
