DOCTOR WHO
BBC America, 8:00 p.m. ET
In “Spyfall, Part 1,” the Doctor Who season opener presented last week, The Doctor’s dilemma was dire: the scheming antagonist was revealed to be a new incarnation of the arch-nemesis The Master, the climax had The Doctor (Jodie Whittaker) sucked into another universe – and beings from that universe were conspiring with The Master to destroy this one. Presumably, the good Doctor will prevail in tonight’s “Spyfall, Part 2” – but how, Who?
