The Lodges' real estate scheme that ends with Archie in prison
Midway through Season 2, Hiram and Hermione Lodge reveal their secret plan to convert the land they've purchased in Riverdale and the Southside into a housing development for employees of a new prison, constructed in the building that used to be Southside High. Since the first season, Hiram has been quietly buying up properties, like the Twilight Drive-In and Pop's, to make way for his business venture, and plotting with rival gangs to take down the Southside Serpents. His "SoDale" project ignited a protest by the Serpents because it's being planned on Southside land -- sacred land that was stolen from the native Uktena tribe hundreds of years ago by a man who the citizens of Riverdale now celebrate with Pickens Day.
Later in Season 2, unable to break up Archie and Veronica's relationship, Hiram decides to bring Archie into the fold, testing his loyalty while Archie believes he's spying on the Lodges for the FBI. The agent, who keeps appearing to Archie at inconvenient moments and threatening him and his father, is revealed to be a plant by Hermione to test him.
In order to consolidate his hold over Riverdale and the Southside, Hiram attempts to purchase one last property: the Whyte Wyrm, the Serpents' local hangout. But his own daughter Veronica gets there first, saying she'll trade the Wyrm, plus her stake in the family business, for Pop's, because the diner is the last place she and her friends can call home. Hiram agrees to the terms, but at the very end of the finale, in order to break up Veronica and her friends, Hiram has Archie arrested right after he's elected student body president.
Will Archie make it out of prison? Will Veronica finally get one over on her tricky family? Will their town ever be a safe place again? One thing's for sure: Riverdale is a great show about how to be a terrible parent.
