Dan Lewis

Daniel Lewis, or Dan for short, 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.
