- 1995 - Writer Matthew Jacobs submitted his first full script for the 1996 TV movie, based on his 27 June planned storyline. At this point, the script resembled the final product very closely. Jack became Chang Lee, the Bruce Master's host body was named Bruce and Kelly Grace was renamed Grace Wilson. The Eye of Harmony was introduced into the plot, and was at this point used by the Master as a link to the dead. In the end, the four travel through the Eye to the dimension of the dead, and the Doctor saves Grace and Chang Lee by conjuring his dead mother's ghost. The Master is destroyed and the Doctor leaves in his TARDIS, alone. After receiving input, Jacobs submitted his next draft on 18 August.
