Doctor Who showrunner Steven Moffat has said that he expects Nardole is “going to end up being in all of [the new season].”

12 new Doctor Who episodes have been filming in Cardiff since June 2016 and will begin airing on BBC One this April.

Here’s everything we know so far about Season 10.

Little Britain star Matt Lucas made his debut as Nardole, who met the Doctor on the human colony of Mendorax Dellora in the year 5343, in 2015’s Christmas special, ‘The Husbands of River Song’ and returned in last month’s ‘The Return of Doctor Mysterio’.

Moffat has now revealed: “He was contracted for certain episodes [of the 2017 series], and he’s crept into far more of them. I think he’s going to end up being in all of them, in fact, because we love him.”

He added: “In the first episodes of [Season 10], he’s slightly broader, but we more clearly establish in this Christmas one that he’s sly, and clever, and daft – but he’s not just rent-a-duffer, as he was in ‘The Husbands of River Song’, where he was a relatively small character, killed off early on, who happened to be played by Matt Lucas. This is a chance to slightly reconfigure him. He’s a wee bit cheeky to the Doctor, but he’s genuinely helpful and good at things.”

Update: Lucas has since tweeted to clarify that Nardole will appear in “not every episode” of Season 10.

Matt Lucas also teased: “Nardole is the first non-human companion in quite a long time… he knows things even the Doctor wouldn’t know!”

Lucas previously revealed that “Nardole is becoming more textured” in Season 10’s episodes.
