Season 1 of the TV show Mayfair Witches concluded with the main character, Rowan, giving birth to Lasher, a powerful demon, after being manipulated by several men. The finale, titled "What Rough Beast," referenced Yeats' poem, mirroring the show's themes of gender, sex, and consent. Key plot points included the revelation of a conspiracy between the Talamasca and Cortland Mayfair, and Rowan's ultimate rejection of both men to escape with her baby. Season 2 will adapt the second book, Lasher, with Rowan fleeing to Europe while dealing with her rapidly aging demon son and the ongoing threat from the Mayfairs and the Talamasca.
