### Summary
A new conspiracy unfolds, orchestrated by the despised High Priestess Debien and the Empress Dowager Medea. Their plan centers on the sacred title of "Arabella," a position they intend to use to unseal a dangerous, sealed power known as Ephialtes, a process widely believed to be fatal for the chosen individual. The plot takes a sharp turn when Leslie's sister, Ellie, makes a surprise appearance, her expression mirroring the High Priestess's manipulative demeanor. In a move perceived as a major red flag by observers, Ellie unexpectedly nominates Leslie for the dangerous role, confirming suspicions that Leslie is being set up as a sacrifice. This development has intensified reader frustration towards the smug, scheming villains and sparked theories that Ellie is knowingly complicit in the plot to have Leslie killed. Amidst the rising tension, a quiet, supportive moment between Leslie and Conrad is highlighted, with many noting he still cherishes a handkerchief she once gave him. Overall, the chapter leaves readers with heightened anxiety, hoping Leslie recognizes the blatant deception and communicates openly with her Salvator family to avoid the villains' trap.
