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.. (TV: The Halloween Apocalypse)

Circa the mid 2000s, Dan was engaged and due to be married. However, two days before the wedding, his fiancée changed her mind. She informed him that she "couldn't bear spending the rest of her life with [him]" and "thought she could do better". Dan had truly loved her. (TV: Once, Upon Time)

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 volunteered at Jenning Street Food Bank, but refused to take home soup for himself when offered, even though he had no food at home. (TV: The Halloween Apocalypse)

Dan surprised his friend Diane with a skinny latte as she was leaving work. The pair went on a walk around Liverpool. When she asked him why he wasn't married, he told her about what had happened with his fiancee. (TV: Once, Upon Time)

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

Meeting 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, both because he was an adult, and because he was 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.

Meanwhile, the Thirteenth Doctor and Yasmin Khan followed Karvanista's trail to Dan's house, which was miniaturised when they triggered technology he had planted there.

The Doctor and Yaz came to rescue him, confronted Karvanista, and took Dan aboard the Doctor's TARDIS. (TV: The Halloween Apocalypse)

Travels in the TARDIS
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...)

Dan and Karvanista later teamed up together to destroy the Sontaran fleet of timeships that were posed to invade all of Earth's history. The two managed to escape using a waste chute. When the Doctor returned, Dan accepted her offer to join her as she departed for the planet Time. On Time, Swarm was waiting for them in the Temple of Atropos. He had put Yaz and Vinder in the places of two Mouri, and prepared to expose them to the full force of time. (TV: War of the Sontarans)

The Doctor shoved Dan onto a Mouri pedestal, while she leapt onto another and used her sonic screwdriver, trapping Dan, Yaz, Vinder and herself in a time storm.

Protected in his time stream by the Doctor, Dan relived a day he went on a walk with Diane, and discussed his past relationships. However, Dan noticed some inconsistencies, such as time passing in the blink of an eye. Fidgeting out of his time stream, Dan found himself somewhere else. He ran into Joseph Williamson while running away, though he wasn't quite sure from what he was running.

While Dan was safe, trapped in a memory, the Doctor replaced the missing Mouri and safely returned Dan to the temple. Swarm showed Dan a glimpse of Diane, who he had kidnapped and imprisoned in a Passenger. Vinder and later the Doctor promised to help Dan save her. (TV: Once, Upon Time)

Personality
Dan considered others' needs often before his own, volunteering at his local food bank and giving out treats for Halloween while he did not have food for himself at home. According to Wilma, whom he volunteered with, 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 must have been 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 Dan in particular for a reason. (TV: The Halloween Apocalypse)

Nonetheless, he remained open to new possibilities, and adapted quickly, even joking that he had a friend with a TARDIS which was even "bigger", moments into first encountering dimensional transcendentalism. (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.
 * An art card of Dan Lewis was included in DWM 570.
 * 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.
 * After The Halloween Apocalypse first aired, "Evil Dan", an internet meme humorously depicting Dan as a nihilistic, gluttonous villain in fan-edited videos, rapidly became popular on YouTube and Twitter. In the week following the broadcast of War of the Sontarans, Bishop retweeted one of the videos and said that he loved it.
