Diane (The Halloween Apocalypse)

Diane worked at the Museum of Liverpool in 2021. She was a friend of Dan Lewis, who often referred to her simply as "Di".

On Halloween 2021, she chastised Dan for impersonating a guide at the museum before arranging to meet him for drinks later that night. Dan agreed, but was abducted by Karvanista before he could attend.

While waiting for Dan as agreed on the corner of Lark Lane, Diane was pulled into an empty building by Azure, who told her: "We're going to have fun with you". (TV: The Halloween Apocalypse) They placed Diane within Passenger, in order to use her as a hostage. (TV: Once, Upon Time)

Dan attempted to phone Diane when he returned to Granger Street at 20:10 on 2 November, but he was unable to get through to her. (TV: War of the Sontarans) Later, in the Temple of Atropos, Swarm taunted Dan by revealing her to him. Dan was unwilling to leave the Temple, singularly focused on rescuing Diane, but the Thirteenth Doctor explained that she had left with the Ravagers. (TV: Once, Upon Time)
