Luke and the main character continue to investigate Oedipus by collecting information about his network of corrupt detectives. Luke gives the MC a key to his home, causing a small disagreement about which from a pair of matching keychains they should each take.
Sphynx calls and suggests the two pursue Nami Hidaka as a lead, due to Oedipus' emergence coinciding with the death of corrupt detective Jae Gim, who'd had dealings with Nami as a debtor to Beddo Lending. Sphynx theorizes that Jae, in his role as a shady information broker, may have discovered something about Oedipus that Oedipus is targeting Sphynx in order to silence, and that Nami may have discovered this information in Jae's last days.
