Back in the Temple, the real Keltham is asking Ione, now, about what Project Lawful was - actually like. From the inside. What she knew before Nefreti's intervention, without spoilers, about what happened to Peranza, if that's something Ione can say.
If Ione had any idea herself, before Nefreti, about how much of the Carissa that Keltham loved, was real. If she would have actually cared about paying an INT 14 Osirian woman's tuition to the Temple of Nethys, or setting up factory-sanctuaries for women who want to earn their way out of the country.
