Kris and Susie's nightmares before entering the Dark World in the Holidays' house. Susie's starts out innocently enough with her meeting up with Noelle. It becomes progressively creepier as Susie starts talking about how hungry she is and how tasty Noelle looks, while slowly getting bigger and growing sharper and sharper teeth while Noelle seems completely oblivious to the danger. It finally ends with Susie eating Noelle alive. You can understand why Susie looks just a bit unnerved when she wakes up. Kris seemingly re-lives an event in their early childhood in which they were locked into a container, while two mysterious people on the outside talk about "connections". It doesn't help that right after Kris wakes up, they once again try to escape the SOUL but fail miserably.
The "confess your sins" trial in the church Dark World has two for the price of one:
Susie reveals she suffers from a Horror Hunger, and she lives in constant fear she's going to snap and try to eat one of the other people in town.
Kris reveals the existence of the SOUL controlling them, and it's textbook Existential Horror. As they explain, they have no idea what is controlling them, what it wants, or why, or even if they have any SOUL of their own outside of it. Worse, Kris is terrified that, eventually, the burden of being controlled by this alien force from outside of their perspective will cause them to snap and go on a killing spree to see if being alone will cause it to finally stop taking control of them.
Page 58 implies that Toriel and the other "old guard" monsters wiped out a whole town of humans. In self-defense, perhaps...except then they took over said town and claimed it was always theirs, erasing all memory of the humans.
Page 63 is a Wham Episode of the highest order. All the residents of the Card Kingdom have been recovered, all the fountains sealed...except that from Lairse's journal entry, it seems that Asriel was broken by the Awful Truth about the past, and left for college to get as far away from his hometown as he could. We don't know what said truth was, but it can't have been anything good.
Page 67 has the Knight offer some key revelations, chief among them the fact that their plans are proceeding as intended despite the Lightners closing the Fountains of Darkness. Oh, and they just happen to be a Lightner, themselves. The Spade King's reaction to this is rather terrifying, his face distorting as he howls his outrage at the Knight...who's barely fazed by this.
And it's implied that even if the Spade King weren't locked up, the Knight wouldn't be bothered by him anyway. Just what kind of power does the Knight have?
The ending. Darkness spills out and floods the town as Darkners begin to appear in the real world, all set to the Evil Gloating of the Knight, who is revealed to be a Driven to Madness, human Ax-Crazy Gaster. It truly looks like the Apocalypse came to Hometown.
