Cheryl revisits the history of her ancestors and gets a visit from her good friend Sabrina Spellman.
Tropes:
- And Now You Must Marry Me: Fen at first tries to manipulate Abigail into marrying him by forging a letter from her deceased brother James urging her to marry Fen. When Abigail discovers evidence of this forgery, along with Fen being a murderous warlock whose victims include James, Fen switches tactics and instead forces Abigail to marry him by threatening to kill Thomasina.
- Artistic License – Law: Poppy is in a jail cell for nine months straight and never gets any lawyer or a trial. All of these are in violation of her rights, regardless of what she’s done.
- Audience Surrogate: Britta joins in during the second act and her reactions mirror the audience, such as concern for Bitsy or confusion at the ritual.
- Bittersweet Ending: Or as Sabrina puts it, Happy-Sad Ending. Nana Rose dies but not before her soul gets transferred into Cheryl’s body and vice versa. Because Cheryl and Poppy were actually Abigail who was cursed with immortality and now gets to join her great love Thomasina in the Afterlife.
- Collateral Angst: In contrast to Bitsy, who it white and gets her own narrative, Thomasina's experience has little to no space in the plot and she is killed off for Abigail's white pain to last a century.
- Deliberate Values Dissonance: All over the place in both Abigail and Poppy’s stories.
- Domestic Abuse: Jack Smith is implied to be abusive towards Bitsy.
- Exact Words: Poppy is promised that if she helps Bitsy she'll "never go back to your cell." It's only after she does that she learns that doesn't mean she'll go free, as she's placed on house arrest for the rest of her life. Although since she is the immortal Abigail, it's really for the rest of her captors' lives.
- "Freaky Friday" Flip: A voluntary one for Nana Rose and Cheryl, who swap bodies as Rose is dying. Cheryl, who is actually Abigail, finally gets move on to the afterlife while Nana Rose gets to be a young woman again.
- Noodle Incident: Sabrina mentioning that she died and came back; while her death wasn’t a Noodle Incident, it’s still a mystery how she came back.
- No Woman's Land: Rivervale was a rather sexist place in the 1950s.
- Perfect Poison: Bitsy eventually stirs the poison Poppy gave her all those years ago into Jack’s drink, killing him and leaving absolutely no trace. It’s supposed that being an herb-based poison made it harder to detect, though Poppy being a witch probably has more to do with it.
- Straw Misogynist: All of the husbands in Poppy’s story treat their wives badly, especially Jack Smith. And when they fight back, Poppy is blamed.
- Fen calls Abigail and Thomasina "women" rather than their names and forces the former to marry him.
