Jenny and her Silurian partner, Madame Vastra, proved to be popular characters when aiding the Doctor in A Good Man Goes To War. Since then, fans have talked about their return and maybe even a potential Doctor Who spin-off. It even inspired some excellent fan work like you can see pictured to the right (credit Bill Mudron).

But it turns out it wasn’t just fan fiction, Steven Moffat himself said he thought about a spin-off for the pair.

“I instantly pitched it to Ben Stephenson [Controller, Drama Commissioning],” Moffat told SFX. “He just said ‘…Yes!’. And then I said ‘I obviously don’t have time to do this…’ [laughs].”

But all hope is not lost, because it sounds like we could be seeing more of them in future.

“I think I might revisit them,” reveals Moffat. “They were great fun to write. Obviously the first person to think about a spin-off was me, when I was writing ‘A Good Man Goes To War’… A Victorian Silurian? Her lesbian maid? Come on!

“I was pleased by the reaction to them, but not surprised. They really cut through as characters, given how little screentime they had. I certainly wouldn’t be averse to them returning. It’s just a thing that worked, isn’t it? I love that Victorian setting, and having kicked it out of Sherlock Holmes I can always kick it in somewhere else!”
