so this specter was actually present during Rattlejack's brawl with the Shade yesterday-- she's who he was talking to throughout the fight. nobody can see hear or even detect her presence except for Rattleback and God himself. Like Rattlejack she was a sinner in life but unlike him she didnt get to leave in a physical form- her real body remains in hell and is not punished bc she does God's dirty work with Rattleback
