Archon took the identity of Lux (Pussy) to avoid a fatal situation in NYC. Only Asmodeus knows of the switcheroo.
Geoffrey “Little Pussy” Moltisanti started out as a cat burglar and was affectionately known as Pussy because of this earlier career (“Pussy” in reference to a “pussy cat”). He is called “Little Pussy” to avoid confusion with Silvio “Big Pussy” Altieri.
Little Pussy runs an auto body shop in Brooklyn.
