Dan Lewis

Daniel Lewis, Dan for short, was a Liverpudlian companion of the Thirteenth Doctor, becoming a member of "Team TARDIS" after Yasmin Khan, following the recent departure of Graham O'Brien and Ryan Sinclair.

Life in Liverpool
Following the 2021 Dalek civil war, that New Year's Day, Dan's friend read out Dan's horoscope, which foretold that: Dan, an Aries, would find surprises later that year, the colour blue and the letter D would be important, as well as thirteen being his lucky number, to be prepared for action, and to remember that, no matter what, it wouldn't be the end of the world. After his friend finished, Dan closed the rear doors of his Ford Transit, turned, and smiled. (TV: Welcome to the TARDIS...)

Travelling with Team TARDIS
On Halloween night later that year, Dan was kidnapped by Karvanista and found himself on Karvanista's ship. The Doctor and Yaz came to rescue him. (TV: The Halloween Apocalypse)

Both Dan and Yaz were studiously operating the TARDIS when the Thirteenth Doctor sent a distress call about the arrival of the Flux. Dan then called out to the Doctor, saying that he and Yaz needed her help. (WC: The Flux is Coming...)
