WARNING: Contains SPOILERS for Doctor Who - "The Giggle."

Summary

• Doctor Who's final 60th anniversary special sets up a potential spinoff show featuring UNIT on Disney+.
• The new UNIT team in "The Giggle" showcases a strong camaraderie and dynamic, laying the groundwork for future appearances and a possible spinoff.
• The introduction of the Vlinx, a new robot working for UNIT, hints at potential backstory and teases a potential UNIT show on Disney+.

Doctor Who's final 60th anniversary special, "The Giggle" has set up the rumored UNIT spinoff show on Disney+ in multiple ways. Now installed in a flashy new skyscraper in central London, UNIT recall the Fourteenth Doctor (David Tennant) to help them stop the world from going mad. Although the main draw of "The Giggle" is the battle between the Doctor and the Toymaker (Neil Patrick Harris), there's a sense that it's setting up a future UNIT spinoff. Doctor Who spinoffs on Disney+ have been heavily rumored since the co-production deal was announced. The new Whoniverse title also implies that Doctor Who will have its own expansive fictional universe.

Doctor Who's rumored UNIT spinoff would be led by Jemma Redgrave's Kate Stewart, the daughter of Brigadier Alistair Gordon Lethbridge-Stewart (Nicholas Courtney). Following on from the reveal in "The Power of the Doctor" that UNIT hires former Doctor Who companions as freelancers, it's expected that some classic series actors will reprise their roles. "The Giggle" outlines the structure of the new UNIT, which gives the sense of Doctor Who's final 60th anniversary special being a backdoor pilot for a new spinoff.

8 UNIT's Brand New Headquarters

It looks a lot like the Avengers Tower.

Doctor Who's UNIT have never had the best of luck with their HQs in the modern series. Their New York HQ and the Valiant were devastated by the Daleks in "The Stolen Earth", their presidential plane was blown up by Zygons in "The Zygon Invasion", and their brand-new building was blown up by Tegan Jovanka (Jane Fielding) in "The Power of the Doctor." The biggest surprise of "The Giggle" is that the UNIT skyscraper largely remains standing after their confrontation with the Toymaker. Giving UNIT a permanent base of operations does feel like a way to establish the Doctor Who spinoff show's primary location.

7 The Dynamic Between The New UNIT Team

Doctor Who's new UNIT work brilliantly together.

In the 1970s, Doctor Who had the UNIT family, so-called because of the warm relationships between the Third Doctor (Jon Pertwee), his companions and the UNIT team. There's a sense of this camaraderie in "The Giggle", with Shirley Anne Bingham (Ruth Madeley) quickly forgiving Kate for her ableist abuse while under the influence of the Toymaker. This is clearly a team that trusts each other implicitly, much like the UNIT team of old. A strong central team structure is a strong foundation for their future appearances in Doctor Who, but it also guarantees good grounding for a spinoff show.

6 The Vlinx

What's going on with UNIT's new robot?

The Vlinx (Nicholas Briggs) feels like the most obvious bit of set up for Doctor Who's UNIT spinoff. There must be many stories to tell about how the Vlinx came to Earth and began working for UNIT. They appear to be a robotic version of James Bond's Q, providing UNIT with gadgets and technology to meet alien threats. The Vlinx invented the Zeedex that shielded UNIT from the effects of "The Giggle", and would presumably fulfill a similar purpose in future appearances. Doctor Who's new robot also draws comparisons with Mr. Smith (Alexander Armstrong) from Russell T Davies' previous spinoff show, The Sarah Jane Adventures, further teasing a potential UNIT show.

5 The Galvanic Beam

UNIT is sufficiently tooled up to fight alien threats.

The galvanic beam that triggered Doctor Who's first bi-generation is more evidence of the substantial tools that UNIT have at their disposal. Way back in David Tennant's first-ever episode, "The Christmas Invasion", the Torchwood Institute had a similarly powerful weapon trained on the Sycorax spaceship. The reveals about Torchwood recurred throughout David Tennant's first Doctor Who season, culminating in their introduction in the season 2 finale and the eventual John Barrowman-led spinoff. It's possible that the galvanic beam is a subtle callback, with future UNIT episodes in Ncuti Gatwa's era eventually paving the way for a full series order for a UNIT spinoff on Disney+.

4 UNIT Offers Donna A Job

Could Catherine Tate come back in a spinoff show?

Donna brilliantly figures out that the brain signal resembles a tune, eventually inspiring the Doctor to recognize that it's the giggle of Stooky Bill stored in broadcast signals. The super temp from Chiswick impresses Kate Stewart so much that she offers Donna a job with a generous pay package and benefits. Donna doesn't explicitly accept the job on-screen, but the money will give her cash-strapped family the chance to relax more. Interestingly, Yasmin Finney is said to return for Ncuti Gatwa's first season of Doctor Who, perhaps interning for UNIT. If Donna's daughter is still in the new era of Doctor Who, then it's easy enough for her to pop up in a UNIT spinoff in a special guest role.

3 Doctor Who's Mel Now Works For UNIT

The 1980s companion will be back next season, too.

Kate Stewart fulfilled her promise to the Doctor Who companion group by hiring Mel as a computer expert for UNIT. If Russell T Davies is repeating some of his past glories, he could do a lot worse than put Bonnie Langford front and center in her own show. That's what he did with Elisabeth Sladen and The Sarah Jane Adventures in 2006, so it would make a lot of sense to do the same with Langford. While Mel was a divisive Doctor Who companion, Bonnie Langford is an excellent actress with a big public profile thanks to her West End and Broadway experience. There could be nobody better to lead the UNIT spinoff alongside Jemma Redgrave.

2 UNIT Are Hiring Former Doctor Who Companions

It's not just Donna and Mel.

While executive producing The Sarah Jane Adventures, Russell T Davies brought back both the Brigadier and Jo Grant (Katy Manning). He also planned to bring back Sophie Aldred as Ace, had Elisabeth Sladen not sadly ed away before filming on season 5 completed. RTD clearly doesn't want to crowd the new show with old faces, and that's the right decision as Ncuti Gatwa's Doctor Who is being billed as a fresh start. However, with Mel, Tegan, Ace, and potentially Donna Noble on the payroll, there's a real possibility that other classic Doctor Who companions will be brought into a UNIT spinoff show to provide their own unique expertise.

1 UNIT Has An Earthbound Doctor Again

David Tennant's 14th Doctor remains on Earth.

50 years after the Third Doctor's exile to Earth ended, the Fourteenth Doctor's is just beginning. While this is a self-imposed exile designed to give the Doctor time to rest, reflect, and enjoy a normal life, UNIT will be reassured to know they've got him on speed dial. Russell T Davies making the decision to keep around David Tennant after Doctor Who feels like a calculated move to bring back the Fourteenth Doctor when the story demands it. Having the retired Fourteenth Doctor occasionally feature as an advisory figure in the new UNIT spinoff could provide an interesting new spin on Doctor Who tropes that wouldn't undermine his heartwarming happy ending.

Doctor Who returns to BBC One and Disney+ on Christmas Day. All three 60th anniversary specials are available to stream now.
