John Hallam shows up as one of Doctor Who‘s immortal super-being characters in this story’s final episode. I don’t know that Light is in the same league as the White and Black Guardians or the Eternals. He’s kind of stupid. Tens of thousands of years ago, he came to Earth and catalogued all life on the planet and then went to sleep. Light’s never encountered life that evolves before now, and when he wakes up in 1883, he becomes furious and the Doctor talks him into one of those “does not compute… self-destruct!” moments that we saw, with eyes rolled, on television in the sixties and seventies, or at the end of “The Daemons.”
At least Light’s goal made sense to our son. I gave him a recap over supper, and we talked about the show afterward, and he understood that Light wanted to catalog everything without it evolving. He also understood that Control, who has evolved into a female humanoid with good dress sense, wanted to be free. He didn’t understand anything else at all, which makes him a member of a very large club. Maybe after nineteen more viewings and twenty thousand online reviews and blog posts, he’ll figure it out.
