Dan Lewis

Daniel "Dan" Lewis was a companion of the Thirteenth Doctor. He joined Yasmin Khan in the Doctor's TARDIS as they faced the Flux, an unforeseen threat to the very structure of the cosmos.

Dan lived a simple life in Liverpool before being thrust into the Doctor's world. He remained open and inquisitive, and challenged Karvanista when he was taken away from home, to outer space. He was interested, most of all, in other people.

Life in Liverpool
Dan was born an Aries. (TV: Welcome to the TARDIS...) He lived in the Anfield district of Liverpool at 37 Granger Street and supported Liverpool F.C.. He volunteered at Jenning Street Food Bank, but refused to take home soup for himself when offered, though he had no food at home. (TV: The Halloween Apocalypse)

Following the 2021 Dalek civil war, Dan's friend read out Dan's horoscope, which foretold that he would find surprises later that year, that the colour blue and the letter D would be important and that thirteen would be his lucky number. He was told to be prepared for action and to remember that, no matter what, it would not 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...)

Dan regularly took groups round the Museum of Liverpool in an unofficial capacity, against the wishes of Museum management. Though Diane had a close, bordering on romantic, relationship with Dan, Alan threatened to ban him permanently. (TV: The Halloween Apocalypse)

Travelling with the Doctor
On Halloween night, 2021, Dan was in his home on Granger Street in Anfield, when three children came to his house, trick-or-treating. He gave them the last of his sweets, and they left. A few seconds later, a man came to Dan's home, asking for sweets; Dan turned him away, as he was not only too old, but also not even dressed up. Later that night, Dan was kidnapped by Karvanista, who intended to rescue him from the Flux. He found himself on Karvanista's ship. The Doctor and Yaz came to rescue him, and took Dan aboard the TARDIS. (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...)

Personality
Dan considered others' needs often before his own, volunteering at a food bank and giving out treats for Halloween while he did not have food for himself at home. According to his colleague, his continued refusal to take food home was a matter of pride. (TV: The Halloween Apocalypse)

Liverpool was central to Dan's identity. He knew much about the city, and felt strongly about its rivalry with Leeds. He even distrusted Yasmin Khan, at least in jest, for her association with Sheffield, which was "too close to Leeds". (TV: The Halloween Apocalypse)

When faced with the unknown, Dan tended towards quick, rational conclusions, and had no trouble asserting his reality. He reasoned that an adult trick-or-treater should not be given candy, that Karvanista was play-acting in costume, and should leave his home, and later, when faced with the reality of Karvanista's spaceship, that he must have captured him in particular for a reason. (TV: The Halloween Apocalypse)

Skills
As part of the crew, Dan played his part in operating the controls of the TARDIS control console. (WC: The Flux is Coming...)

Behind the scenes

 * As Dan Lewis is said to be an Aries, this would place the character's date of birth from 20 March to 21 April, if the Zodiac of the real world holds true in the Doctor Who universe.
 * Dan appeared in the invalid webcast A Message.
 * Dan Lewis' apparent dislike for Leeds, and nearby Sheffield, in The Halloween Apocalypse is most likely banter, stemming from the historic rivalry between Lancashire and Yorkshire. Dan is a born Liverpudlian, and the city of Liverpool was historically part of Lancashire before the reform of county boundaries in 1974; both Leeds and Sheffield are typical Yorkshire cities.
