We had so much to say about this one that we couldn't fit it into a single episode! So here's what turned out to be the first part of our discussion of this frankly stunning episode. We talk about how this feels ambitious in a way even this era's best stories generally haven't. We look at how Flux is progressing Yaz and the Doctor's relationship at long last. We marvel at all the several great performances, and we talk about the big surprise guest star. (No, not Barbara Flynn. To Alasdair's great chagrin, we ran out of time to talk about her. But hey, part two incoming Saturday!)
