When Pearl Mackie joins the TARDIS for Doctor Who’s upcoming tenth season as the new companion, she’ll be accompanied by a familiar face in the space-time continuum. It’s confirmed that Matt Lucas — who delightfully played River Song’s assistant Nardole in last year’s Christmas Special — will be reprising his role in the season premiere, with executive producer and lead writer Steven Moffat noting “this time it’s not just for Christmas, he’s sticking around.†Will Nardole’s decapitated head still be in the Hydroflax’s body? And is Hydroflax still waiting tables at an upscale intergalactic restaurant? The details of his arc are unknown, with season ten expected to premiere in early 2017. If only we had a TARDIS key now, huh?
