For every bad grandpa, there's an even worse grandma. At Litchfield, that person is Frieda Berlin. One of the prison's "golden girls," Frieda has loads of expertise in the art of Lorena Bobbitting (she cut off her husband's penis with a dull knife), body disposal, and good old-fashioned murder. Between casually mentioning that she's killed at least four people and helping Alex bury a would-be assassin's body, Frieda keeps her prison life stimulating by always being on hand for all the lethal tasks. We would say we want to see more of her backstory next season, but quite frankly, we're scared.
