Dwight’s cousin who kidnaps Angela during the finale of "The Office" is Mose. Mose Schrute is Dwight’s eccentric cousin and a recurring member of the Schrute family who lives and works at Dwight’s beet farm.
In the series finale, Dwight and Angela are preparing for their wedding. As part of a Schrute family tradition connected to the wedding celebrations, Mose abducts Angela and takes her to a bar owned by Kevin Malone. Dwight eventually tracks her down and brings the chaotic tradition to an end.
Mose is played by Michael Schur, who also co-created the American version of The Office and later created shows including Parks and Recreation and Brooklyn Nine-Nine. The character appears in several episodes, usually contributing bizarre ideas, awkward physical comedy, or unsettling Schrute family customs.
Viewers sometimes confuse Mose with other Dwight relatives mentioned in the series, but the finale specifically identifies Mose as the cousin responsible for Angela’s kidnapping. The episode aired on May 16, 2013, ending the show’s nine-season run.
