After the Doctor's origins (as well as the series canon in general) were blown apart at the end of the last series, nobody quite knows where Doctor Who is headed next. One thing is for sure though - ending on such a divisive note means the next episode ideally needs to follow up with something familiar. And that's exactly what showrunner Chris Chibnall did for the 2020/2021 New Years Special, as the Doctor's greatest foes returned once more in Revolution of the Daleks. Written by Chibnall and directed by Lee Haven Jones, this episode sees the exit of companions Graham O'Brien (Bradley Walsh) and Ryan Sinclair (Tosin Cole), as well as the proper return of Captain Jack Harkness (John Barrowman) - something that was teased all the way back in Fugitive of the Judoon.
