Warning: Spoilers ahead forDoctor Whoseason 14, episode 7, “The Legend of Ruby Sunday.”

Summary

Doctor Whoseason 14, episode 7, “The Legend of Ruby Sunday,” introduces a new UNIT science advisor in place of Shirley Anne Bingham, but there’s a narrative reason for the personnel change.Doctor Who’s UNIT dates back to the show’s classic era, and the organization seems to have a bigger part to play than usual in Russell T Davies' second stint as showrunner. Since returning in theDoctor Who60th-anniversary specials,UNIT has been proven to consist of faces old and new. This is a trend that continues in the penultimate episode ofDoctor Whoseason 14.

Ruth Madely first played Shirley in “The Star Beast,“and last appeared in “The Giggle.” So, her appearances bookend David Tennant’s anniversary trilogy. “The Legend of Ruby Sunday” is the first meaningful return of UNIT since “The Giggle.” However, the fact she’s been replaced with a new science advisor isn’t explained during the episode. Thankfully, she will return at a later point inDoctor Who’s Disney era.

UNIT’s scientific advisor in “The Legend of Ruby Sunday” is Lenny Rush’s Morris Gibbons. The thirteen-year-old genius is incredibly intelligent, “Thanks to a passing asteroid.” While he is a more-than-capable replacement for Shirley,Russell T Davies has confirmed that Morris is only a stand-infor Madely’sDoctor Whocharacter. Speaking withDoctor Who Magazine(viaRadio Times), Davies explained that Morris is there, “While [Shirley’s] in Geneva.”

Doctor Who’s final 60th anniversary special, “The Giggle” feels like a backdoor pilot for a UNIT spinoff starring Bonnie Langford and Jemma Redgrave.

As a UNIT employee, the promise of more appearances from Shirley means the fictitious organization will continue to have a major role in the show’s future. In fact, with rumors swirling of a UNIT spinoff show,Shirley could be appearing in theDoctor Whouniverse far more often. If a UNIT spinoff does happen, then there could even be room for Lenny Rush’sDoctor Whocharacter to remain as a regular contributor.
