Locked Tomb AU where Cytherea rolls up to Canaan House fully ready to engage in a whole bunch of murder up to and ideally including deicide only to take one look at Gideon’s face, do the math of “A. L.’s eyes + Commander Wake’s face + Ninth House teenager = John is a lying liar who lies”, and decide to flip the plan from “If they all die that’ll show him!” to “If they all live that’ll show him!”
John sends somebody to pick up the survivors or whatever the original plan was and well over half the cast is wandering around with the wrong eyeballs. Opinions range from “genuinely thought this was how the original lyctors did it” (the Fourth) to “knows full well that somebody tampered with the notes to make it look like there was always an extra step that you have to figure out on your own, but this is better than what they originally did so whatever” (the Sixth) to “honestly disappointed they were stopped from going with the murder option” (Ianthe)
No one in the First is happy about this but too late now!
