I might just squee for a bit, rather non-verbally, but basically once again I loved this. The grownups are back in charge. Gatwa and Gibson are a great pair. The alternate timeline gimmick has been done much worse and more didactically in Who,and elsewhere. Not totally wild about the goblins, but again we have had much worse. And I don’t think we’ve ever had the Doctor actually singing on TV? And what of Anita Dobson’s Mrs Flood – does she really not know the TARDIS at the start, or is she just making that up – have the events of the story changed her, or has she just changed her story?

Seriously though, I took an interest in the plotline about DNA testing, not least because I myself was once able to identify a foundling’s parents through DNA connections (mother then father). For any white person of British and/or Irish descent, there will be loads of connections in the various databases, perhaps not close ones, but they will be there. So we deduce that there’s something very odd about Ruby’s background. But then, the days of relatively normal backgrounds for Doctor Who companions have come and gone, I think.
