10 Doctor Who Mistakes Confirmed By The Creators

10. Clara Being Too Passive

Companions are meant to evolve during their time in the TARDIS. As the Thirteenth Doctor tells her fam in Arachnids in the UK, “You're not gonna come back as the same people that left here.”

Rarely has this been quite as true as it was for Clara.

The Clara of Series 7 is almost a completely different character to the Clara of Series 8 and 9. This radical reinvention was largely down to the Impossible Girl arc, which dominated her first run of adventures.

Making the companion the series arc was an interesting idea on paper, but in practice it created problems, as Steven Moffat has admitted:

“One of the difficulties with her ‘impossible girl’ story was that she wasn’t actually a participant in it, because she didn’t actually know about the mystery. It was always the Doctor fussing about it. She was completely oblivious until the very end, so it doesn’t change her hugely.”

Moffat adjusted in Series 8 and made Clara a much more active character going forward – though some would argue that he over-corrected!
