Story arc and appearances

Bill’s first complete story is the series ten premiere, "The Pilot," in which she meets the Doctor and begins traveling in the TARDIS. Her arc across the series explores themes of identity, mortality, and compassion. The character undergoes dramatic events in later instalments, including a two-part sequence that changes her fate and leads to various narrative consequences for the Doctor and the show.

Although her regular run concludes during the tenth series, Bill also appears in the 2017 Christmas special "Twice Upon a Time," which features an ensemble including the Doctor’s previous incarnations and companions portrayed by actors such as Peter Capaldi, David Bradley, Jenna Coleman and Matt Lucas. That special also involves the character Nardole and other brief returns by familiar figures.

Reception and significance

Critics and viewers praised Bill for bringing emotional honesty and contemporary attitudes to the series. The casting of Pearl Mackie and the portrayal of Bill’s relationship to the Doctor were discussed positively for diversifying the companion role and for offering fresh dynamics with the Doctor’s established personality.
