Thomas Brewster's mother

The mother of Thomas Brewster committed suicide in 1851, jumping off Southwark Bridge into the River Thames. It was claimed at her funeral that she did this due to the burden and shame that giving birth to her son, 4 or 5 years earlier, had brought upon her.

After her death, a being from a potential future used her form to convince Thomas to do its bidding, in an attempt to make its potential future a reality. (AUDIO: The Haunting of Thomas Brewster)

Behind the scenes

 * In 2020, derision arose on Twitter about the fact that this very Wiki's infobox for Thomas Brewster rather tautologically contained "Thomas Brewster's mother" in the "mother" field. This caught the attention of Jonathan Morris himself, who declared that her name was in fact Janet Brewster. However, as it does not come from a valid narrative source, this name is not accepted as a valid part of the Doctor Who universe by this Wiki.
