Dinios Kol reports the severed head and note to Ana, who is less shocked by the brutality than by the killer’s audacity in leaving a written message. Ana immediately argues that this is not the work of an ordinary thief or smuggler, because smugglers do not stage symbolic scenes or leave political quotations behind. When Kol asks about the note, Ana identifies part of it as a line from Emperor Ataska Daavir, which makes the message feel deliberate and politically charged in a city where imperial authority is already unstable.

Ana then considers the note’s other phrase, about “sipping from the marrow,” and connects it to Yarrowdale’s blood economy and the Shroud, where titan blood is harvested. She recalls an old Apoth proposal to extract leviathan marrow and move it inland so it could continue producing blood, which suggests the phrase may point toward forbidden biological research rather than random rhetoric. Although she cannot prove the reference’s meaning, the possibility convinces her that the killer may be signaling knowledge of secret, dangerous work tied to the Apoths.

From the head’s placement in Ghrelin’s safe, Ana draws a new conclusion: the killer is likely an Apoth, and specifically someone who once had authorized access to that exact safe. The preserved head and its banded tooth were clues an Apoth would recognize, and Ana reasons that an Apoth’s expertise with flesh could also explain the impostor’s disguise. She further suspects that the missing item was not the healing grafts the Apoths claimed were stolen, because Ghrelin seemed too eager to open the safe and too distressed by what had truly been taken, implying that the Apoths are hiding some far more valuable and dangerous secret.

Ana lays out her investigative plan. First, she wants records of everyone who has ever had access to Ghrelin’s safe; second, she wants a complete list of all reagent, graft, and precursor thefts in Yarrowdale over the past two years, because this crime may be part of a longer pattern. When Kol recreates Ghrelin’s nervous tapping from memory, Ana realizes the rhythm resembles the same compulsive tapping witnesses described in the false Sujedo, suggesting a possible link between Ghrelin and the impostor, though not yet proof. She decides that their third step will be to interview Ghrelin in person with Apoth superiors present if necessary, and her fourth conclusion is grim: the killer has opened a line of communication and is likely preparing another move, possibly another murder.
