In The West Wing, Josh and Donna's complete relationship timeline has many ups and downs. For nearly seven seasons, the duo did the "will they, won't they" dance, deepening their friendship and professional relationship, all while side-stepping romance. Part of that slow-burn is related to a moral quandary: a White House workplace romance can prove challenging, even if there aren't uneven power dynamics involved. Despite the perpetual back-and-forth, Josh Lyman (Bradley Whitford) and Donna Moss (Janel Moloney) became one of The West Wing's fan-favorite pairings.
