History[]
Harold McFly teamed up with Jules and Verne, whose parents had also been kidnapped, to attempt a rescue, but the plan backfired and all three, along with Doc, were to be beheaded. Fortunately, Clara and Jennivere came to their rescue. Doc suggested that Harold and Jennivere move to Ireland together, instigating the eventual birth of Seamus and Martin McFly in the 19th century.
