Well, all I can say is wow. I almost always read the prog in order, from front to back, but this time I had to start with the last episode of Kingdom. And then I had to stop, and put the prog down, and have a little lie down.*
I definitely did not see that coming. I won't say what it is here, even behind spoiler tags. I'll just say this: do not skip to the end or any nonsense like that, do yourself a favour and read the episode from its first page as the author intended. Then come back here and argue about whether it's the best moment in 2018.
I'll review the rest of the prog when I've read it, in half an hour or so.
*A figure of speech: I was already lying down, I'm still in bed.
