Evil star Mike Colter has teased more of the mysterious Vatican organization known as the “Entity” in season 4. First introduced in Evil season 2, the “Entity” was revealed to be the Catholic Church’s own Secret Service organization represented primarily by the enigmatic Victor LeConte (Brian d'Arcy James). Following the ordination of Colter’s Father David Acosta at the end of season 2, he was later recruited to work for the “Entity” in season 3 by LeConte but has increasingly struggled with the secretive demands it has placed upon him.
