When Edward's sister, Lady Mary, was captured by bandits, Henry led the knights that tried to rescue her. The First Doctor rescued her in his TARDIS, but the knights thought he had magical powers and were afraid of him. With Mary in the TARDIS, the knights chased the Doctor to a castle. They laid siege to the castle.
The Fifth Doctor, summoned by the First, tried to explain to the knights. Henry wanted to kill him, but the Doctor asked to make petition with Edward. Henry agreed, and after the Doctor met with Edward, accompanied the Doctor back to the TARDIS to retrieve Mary. Because Mary was safe, Henry let the Doctor go. (PROSE: Five Card Draw)
