Douglas Adams (in-universe)

Douglas was a friend of the Sixth Doctor, who once answered what was wrong with being drunk with "ask a glass of water". (AUDIO: The Wormery)

Professor Chronotis seemingly once replaced The Worshipful and Ancient Law of Gallifrey in the Panopticon Archives with a book whose title began with The Hitch-, written by one of the "greatest writers" in Earth's history. (PROSE: Shada)

Behind the scenes

 * "Douglas" is a reference to Douglas Adams, who wrote the line about the glass of water in The Hitchhiker's Guide to the Galaxy. Adams also was script editor for Season 17 of Doctor Who, and wrote several scripts for the show himself.
 * This in-universe counterpart to Adams was further detailed in Tom Baker stars in John Lloyd's lost Doctor Who adventure, The Doomsday Contract, as the writer of Hitchhiker's, script editor for Doctor Who, and friend of/coworker with John Lloyd. However, due to being a promotional video, the webcast is not considered a valid source by this wiki.
 * What If? depicts a part in-universe part meta-fictional world revolving around the Richard Griffiths Eighth Doctor.
