Episode 57: “Knock Knock”

This week, we offer our takes on “Knock Knock,” which we generally agree is a pretty good episode with a wonky genre shift and amazing work from Pearl Mackie, Peter Capaldi and David Suchet. All in all, another good one! But first, we respond to Steven Moffat’s new quote from Doctor Who Magazine on the mystery of the vault, run down all the possibilities (it’s a Master, surely it’s got to be), and then branch into a largeAr discussion about the various season-spanning mysteries.
