Sister Mary Loquacious

Sister Mary Loquacious is one of the characters in Amazon's series Good Omens. She is part of a satanic order of nuns.

Personality
Sister Mary Loquacious was the inept nun of the Chattering Order of St. Beryl who managed to fumble the switch of the Antichrist with a human baby, placing the Antichrist with the Young family from Tadfield, instead of with the American Ambassador as had been demoniacally planned for millennia. The Antichrist himself grew up with no demonic or angelic interference, and was a bit too human for the apocalypse to deal with.

Eleven years later she has reinvented herself as Mary Hodges, running the old nunnery as Tadfield Mannor, hosting Corporate Training and team building events.
