Truth and allegiance answer different questions
Conman’s snapshot description gives an in-play disguise and a hidden arrest reveal; it does not contain the “I lie” condition written on many other Underlings. The dated disguise rules allow truthful copies to execute the displayed function.
An announcement agreeing with independently known information can make that particular statement useful. It does not establish that the speaker is normally good. Conman is the reason to keep “statement appears reliable” separate from “resident cleared of evil alignment.”
The Blood Hound self-counting question remains specific
Players have asked what happens when an evil truthful Conman displays Blood Hound. The discussion points out uncertainty about whether that role excludes itself, but it supplies no developer answer or verified behavior used by this guide.
Do not turn that uncertain interaction into a rule such as “it always points at another evil” or “it must always bark.” The Blood Hound page explains the supported row-and-column, tie and no-target rules while leaving this self-counting case open.
