He’s not human, he explains; setting off the land mine wouldn’t simply kill him, it could wipe out half the planet. “I’m a fancy space-time occasion,” the Doctor tells Mundy, enamel gritted and bared, warning her of his terrifying potential. “I’ll shatter this foolish little battlefield of yours into mud.”
Over the many years, the Doctor’s human look has been the downfall of many an adversary. It’s a reasonably normal “Doctor Who” system: Aliens fail to understand that the Doctor is a two-hearted Time Lord and underestimate him till he outsmarts and destroys them. The present’s longstanding villains — the Daleks, the Cybermen — are so feared by the Doctor and cherished by followers as a result of they know what he’s able to, and how you can play the Doctor at his personal recreation.
On Kastarian 3, the drama continues. While making an attempt to deflect the ambulance, Ruby finally ends up getting shot herself, and the Doctor responds with the pained gasp of a wounded animal. But when the ambulance tries to call her subsequent of kin, it, too, falters. As within the final episode, snow falls, identical to on the evening that Ruby was deserted as a child — although this time, it hangs within the air on Kastarian 3.
The solely method to save all of them, the Doctor tells Mundy, is for her military to give up. For the primary time, we see the capability of Gatwa’s Doctor for rage. “There’s no one else right here. You declared struggle on an empty planet,” he rants, including that the military’s troopers didn’t discover they had been alone as a result of they had been placated by religion: “The magic phrase that retains you by no means having to suppose for your self,” the Doctor says.
But the land mine’s clock is ticking down, leaving little room for Mundy (or viewers at house) to seethe on the Doctor’s jab at faith. The Doctor breaks by the A.I. to the true John, however the system glitches and the mine glows inexperienced, solely this time with inexperienced Xs symbolizing a parting “kiss kiss” message between John and his daughter.
It’s a satisfying ending, and Moffat walks again a number of the episode’s critique of non secular warfare when the Doctor admits that simply because he doesn’t like religion, it “doesn’t imply I don’t want it.”
