Betty receives a call from the Black Hood, who wants her to publish a mugshot of her mother, who at the time was a teen on the Southside and threatens to kill Polly unless Betty fulfills his request. Hiram invites the St. Clair's, friends of the Lodges from New York. On the Southside, Jughead attempts to stop Sweet Pea and the Serpents from blowing up the Riverdale Register office and decides to join the gang to prevent unnecessary violence from happening. Betty's next call from the Black Hood tells her to cut ties with Veronica and Jughead and she complies. At the Lodge's house, Nick St. Clair drugs Cheryl and takes her back to his hotel room and attempts to rape her but is stopped by Archie and Veronica. Betty receives a call from the Black Hood telling her to go to an abandoned house, where she'll find who the Black Hood is. Jughead and Toni sit in his trailer, where he tells her his relationship with Betty is over. Back at Betty's house, the Black Hood tells her that by telling Archie, she has broken the rules and he will now kill Polly unless she gives him the name of a "sinner" to kill, to which Betty names Nick St. Clair.
