Zeke is Dwight Schrute's cousin and Mose's brother. His appearances in the show are limited, only being shown during the later seasons.
Season 9
He first appears in Junior Salesman, saying he heard about the open job position from Dwight in the shower.
He drives a motorcycle with a sidecar and is a proficient guitar player. In the episode "The Farm" he describes growing up with Dwight and Mose as not being easy as Dwight was the cool one, Mose was the visionary, and that left him to be the comedian.
He is also seen in the Finale at the bachelor party and is obviously jealous that Jim was chosen to be Dwight's "Bestest Mensch" instead of him.
