Pathologic: The Marble Nest
Shortly after being woken up, Bachelor is informed by Sticky that Blacky's stepfather has become sick. Upon examination, Bachelor determines that Blacky's father has died of a stroke, not Sand Plague.

When Bachelor turns away from declaring Blacky's stepfather dead, he discovers that Blacky has disappeared, replaced by a manifestation of the Plague masquerading as an Executor. Out on the street, a commoner accuses Bachelor of heartlessness for failing to take Blacky under his care.
