Episode 18 of Twin Peaks, "Masked Ball," originally aired on December 15, 1990, and was directed by Duwayne Dunham. Cross-dressing DEA agent Dennis Bryson (David Duchovny) arrives in Twin Peaks to interrogate Agent Cooper, who pleads no defense. Talking with Cooper and Truman, Deputy Hawk reveals important details about White Lodge, the Black Lodge, and what he calls "the Dweller on the Threshold." Meanwhile, James is offered hospitality by Evelyn Marsh (Annette McCarthy) in exchange for fixing her husband's Jaguar. At Twin Peaks High School, the super-powered Nadine takes a fancy to Bobby's friend, Mike Nelson (Gary Hershberger). At the Blue Pine Lodge, Josie reveals secrets to Truman about her past relation to Thomas Eckhardt. In a mysterious association with her brother, Andrew Packard (Dan O'Herlihy), Catherine hires Josie as her maid. Hank comes back from his scheme with Ernie and threatens an unshaven and disheveled Ben Horne with the news that One-Eyed Jacks has been taken over. Cooper gets a message from Windom Earle along with another chess move. That evening, the mayor of Twin Peaks, Duwayne Milford (John Boylan), objects at his brother's wedding.
