Cyberwoman

Lore & Background

The episode was among the first pitched for the series, as creator Russell T Davies saw a potential to continue the story from the Doctor Who episodes "Army of Ghosts" and "Doomsday". Chibnall originally intended the episode to appear midway through the series, but it was brought forward to the fourth slot. It was filmed in the third production block and was among the cheapest episodes due to limited locations and cast. The episode was seen by almost 1.4 million viewers and received generally mixed reactions from critics, though the producers regard it as one of their favourites.

Reader's Guide

In the episode, Ianto Jones has secretly kept his partially converted girlfriend Lisa Hallett in the basement of the Torchwood Hub, hoping to reverse her Cyberman conversion. When her Cyberman influence takes over, she kills a cybernetics expert and attacks the team. Jack Harkness ultimately gives Ianto an ultimatum: kill Lisa or Jack will do it himself. The team opens fire and kills Lisa, leaving Ianto to mourn. The episode is the biggest nod to Doctor Who in the first series, deliberately sending confusing signals about the show's identity. Chibnall included a base description of a Cyberman for viewers unfamiliar with Doctor Who. The episode was the first to centre on Ianto, previously a background character. Chibnall later noted plot holes, including that Lisa's human behaviour was not clearly shown as part of her Cyberman plan, and Jack's cut lip despite his immortality.

Did You Know?

• Chibnall originally intended the episode to appear as the sixth or seventh in the series, but it was brought forward to the fourth slot because some other scripts were not yet completed.
• The scene where the team lines up to execute Lisa was the first scene Chibnall had in mind for the episode; in the first draft, Ianto killed her.
• The episode was filmed in the third production block, along with the eighth episode "They Keep Killing Suzie".

Origins & Production Context

The episode grew directly from the Cyberman storyline in Doctor Who's 'Army of Ghosts' and 'Doomsday,' in which Cybermen from a parallel universe were banished to the void between realities. Russell T Davies recognized an untold story lurking in that aftermath and tasked Chris Chibnall with writing about a cyber girl hidden in the Torchwood Hub's basement. It was among the very first pitches for the series. Chibnall originally planned the installment for the sixth or seventh slot but it was moved up to fourth when other scripts had not yet been completed. Filmed in the third production block, it became one of the cheapest episodes in the first series due to its confined setting and small cast. Before settling on the final title, Chibnall cycled through working names including 'The Trouble with Lisa' and 'The Long Night of Ianto,' ultimately choosing 'Cyberwoman' because, in his assessment, it simply 'says it all.' He also described it as one of his more difficult scripts to write.

Plot & Narrative Arc

Ianto Jones has secretly kept his girlfriend Lisa Hallett alive in the Torchwood Hub's basement, where a conversion unit sustains her half-converted Cyberman body. He brings in cybernetics expert Dr Tanizaki to reverse the process. Tanizaki succeeds in getting Lisa breathing independently, but when he returns to the basement, her Cyberman programming seizes control and she kills him by attempting to upgrade him. The crisis escalates as Lisa drains the Hub's power while Torchwood is pulled away dealing with a rogue UFO. Jack Harkness discovers the situation, stops Gwen from being converted, and attempts to shoot Lisa, but Ianto intervenes to protect her. Jack endures two electrocutions to buy the team time, then uses a special spray to summon the pet pterodactyl Myfanwy, creating a distraction that lets the group escape via the invisible lift. Lisa implants her brain into a pizza delivery girl. Jack gives Ianto an ultimatum: execute Lisa or face execution himself. Ianto returns to the basement, Lisa promises they can be upgraded together, and the team opens fire, killing her.

Character Focus & Thematic Depth

This episode marks the first time Ianto Jones is the narrative center, having been largely a background presence in the first three installments. John Barrowman described his earlier role as akin to Alfred Pennyworth in Batman. Chibnall deliberately framed the opening as a love story, ensuring viewers understood that the half-converted Lisa was still the woman Ianto loved and that she retained her humanity. The writer acknowledged that Ianto's belief in saving her was 'fundamentally wrong,' yet crafted the narrative so audiences would sympathize with his motives and desperation. The episode also serves as the most significant nod to Doctor Who in the entire first series, despite the show's deliberate strategy of sending 'confusing signals' about its relationship to the parent show. Chibnall included a base description of what a Cyberman is for viewers unfamiliar with the source material. The line where Ianto calls Jack 'the biggest monster of them all' was nearly cut from the script but retained for its emotional impact on the audience.

Reception & Production Legacy

Broadcast on BBC Three on 5 November 2006 and repeated on BBC Two on 8 November, the episode attracted nearly 1.4 million viewers. Critical response was generally mixed, yet the producers themselves consider it one of their personal favorites from the first series. Its low budget, stemming from the confined basement setting and small cast, meant it was among the cheapest productions in the run. The pterodactyl fight scene, involving the producers' pet named Myfanwy, was a moment that made the production team laugh and felt essential to include. Chibnall had initially envisioned an airport and hotel sequence for the opening but cut it for cost reasons. He also wanted the episode set weeks after 'Ghost Machine' to demonstrate Gwen's growth from rookie to someone who knew protocols and handled weapons confidently. The execution scene at the finale was actually the first image Chibnall had in mind when conceiving the episode.
