In Katherine's World, Ben stops repossession of Katherine's home by smuggling in a valuable heritage artefact.

The Curse of The Incredibly Bad News

Veronica reveals that Betti is her twin sister, and that the Welkin and Krellicks are part of Betti's army, sent to destroy the remaining Guardians to prevent them interfering with her plans to blandish the Parallax. She also tells Ben that Stefan, not Jeremy, is his real father. An angry and disillusioned Ben refuses to follow her to the refuge in Forest World.

Cheats Never Prosper

Betti finally gets her meeting with Katherine and proudly shows her intended 'partner' around ""Garden World"" as an example of how people live happily and prosper in a blandished world.
