As I've been saying in all of my reviews of this season so far, it adheres to enough essential elements of Asimov's trilogy, and its sequels and prequels, to be immensely enjoyable, at least to me. And it's been doing this while deepening and broadening the original story, as it's been doing and did again in 3.7 to our understanding of Demerzel.
[Spoilers ahead ... ]
But 3.7 did something that Asimov never did. In his narrative, The Mule was a power-hungry mutant, who had the power to literally change people's minds. We readers were supposed to assume, I guess, that the Mule was just born that way. But episode 3.7 has finally given us a much narratively better explanation, by telling us The Mule's backstory.
The Foundation preyed upon The Mule's parents, by allowing them just one child. The Mule's parents had two, and the Foundation representative gave them until its next soon-to-come visit to divest themselves of one of their children. The father decided to save their baby and kill their son, I guess about 11 or 12 years old. As the father was attempting to drown him, the boy discovered that he had the power to mentally direct his parents to drown themselves.
The whole scene was revolting to see. (Seeing or reading a science fiction story in which children are hurt, or worse, is something I never want to do.*) But the whole scene did raise the profound ethical quandary: if you could travel back in time, and eliminate Hitler as a baby, would you do it?
And now, after all these years, we have an answer as to how The Mule arose. Had he not been nearly a victim of the worst kind of violence as a boy, perhaps his mental power would not have arisen. Or, if it had, perhaps he would have used it for good, not evil.
And one last spoiler: the brief conversation The Mule has with Hari in the last moments of the episode -- that's with live Hari not his hologram, since we saw last week that the hologram has no knowledge of The Mule. In a way, that's a happy ending. It's good to see Hari Seldon alive.
*I guess a partial exception is the movie adaptation of Ray Bradbury's "The Last Night of the World" in The Illustrated Man.
