Susan Triad was a tech billionaire and philanthropist. She had founded S Triad Technology. Unbeknownst to her, this attracted the attention of UNIT due to the company being an anagram of TARDIS. She was placed under close surveillance with Melanie Bush being one of her employees.

Mel introduced the Fifteenth Doctor to her who questioned her about the dreams she was having. She was shocked that he knew of them, such as being a Villengard Automated Ambulance Unit or Penny Pepper-Bean. She was taken away from the Doctor to start the speech. She became a bit disorientated during the speech thinking about her dreams. She was used by Sutekh as his servant, causing her to zombify.
