# Catherine Weaver
**Catherine Weaver** is a fictional character in the American television series *Terminator: The Sarah Connor Chronicles* (2008–2009), played by the Scottish singer [Shirley Manson](https://www.edgepedia.org/shirley-manson), lead vocalist of the band [Garbage](https://www.edgepedia.org/garbage-band). Introduced in the season two premiere "Samson & Delilah" (September 8, 2008), she appears as the chief executive of the technology company ZeiraCorp, and is gradually revealed to be a T-1001 Terminator, a liquid-metal infiltrator composed of mimetic polyalloy that can change its shape at will.[1](https://www.wired.com/2008/09/sarah-connors-b/) • [2](https://tvdatabase.fandom.com/wiki/Catherine_Weaver)

## Role in the series
The series, a spin-off from the [Terminator](https://www.edgepedia.org/terminator) films, follows [Sarah Connor](https://www.edgepedia.org/sarah-connor-terminator) ([Lena Headey](https://www.edgepedia.org/lena-headey)) and her son John (Thomas Dekker) as they try to prevent the creation of Skynet, the artificial intelligence that starts a future war against humanity.[5](https://sf-encyclopedia.com/entry/terminator_the_sarah_connor_chronicles) Weaver enters at the start of season two as a new thread running parallel to the Connors' story. In her first episode she buys the Turk, an early chess-playing computer that the show treats as a precursor to Skynet, and begins developing it under a top-secret program she calls Babylon.[6](https://www.avclub.com/terminator-the-sarah-connor-chronicles-samson-and-de-1798204904) • [1](https://www.wired.com/2008/09/sarah-connors-b/)
**The reveal.** The premiere ends with the series' first appearance of a liquid-metal Terminator: Weaver's true form is exposed when she morphs out of a urinal in her own building and kills an employee with a blade of liquid metal extended from her finger.[7](https://www.tvguide.com/news/gee-whiz-sarah-17627/) • [8](https://www.imdb.com/title/tt1245068/characters/nm1276549) Series creator Josh Friedman said the timing was deliberate: he was building the Weaver character and wanted to introduce someone more of an antagonist than "the basic evil corporate type."[7](https://www.tvguide.com/news/gee-whiz-sarah-17627/)
For most of the season the show keeps her purpose ambiguous. She recruits the former FBI agent James Ellison ([Richard T. Jones](https://www.edgepedia.org/richard-t-jones)), telling him the AI under development is a sophisticated computer program that, during a building blackout, reserved generator power for itself so it could grow.[9](https://www.imdb.com/title/tt1245332/characters/nm1276549) Reviewers noted that the series deliberately withheld whether John Henry, the AI she is raising, was meant to replace Skynet or to become a "kinder, gentler version of it."[10](https://strangehorizons.com/wordpress/non-fiction/reviews/terminator-the-sarah-connor-chronicles-season-two/)
## The T-1001 and the human Weaver
[The Terminator](https://www.edgepedia.org/the-terminator) is impersonating a real woman. According to the character database record, the human Catherine Weaver was of Scottish descent, with family from Edinburgh, the same city actress Shirley Manson comes from; she was the wife of Lachlan Weaver and mother of Savannah Weaver, and she died in a helicopter crash in 2002, after which the T-1001 assumed her form.[2](https://tvdatabase.fandom.com/wiki/Catherine_Weaver) The T-1001 continues to raise Savannah as her daughter, a task the show plays for both suspense and unease: in one episode the child tells a therapist she would like her "old mother" back while Weaver watches through a glass partition.[11](https://www.denofgeek.com/tv/terminator-the-sarah-connor-chronicles-season-2-episode-6-review/)
The machine's disguise extends to small physical details. Manson's character keeps part of her liquid-metal mass disguised as an eel in her office fish tank, a detail the actress herself has recalled in interviews.[12](https://www.loudersound.com/features/shirley-manson-on-the-time-she-played-a-terminator) In the finale, when a prototype hunter-killer aircraft crashes into her office and the explosion shatters the tank, the eel flows across the floor, becomes liquid metal, and merges back into Weaver.[4](https://www.denofgeek.com/tv/terminator-the-sarah-connor-chronicles-season-2-episode-22-review/)
## Babylon and John Henry
Weaver's project produces John Henry, an artificial intelligence named for the folklore figure who, as she tells Ellison, raced a steam drill through a mountain: "John Henry defeated the machine. But he couldn't stop progress."[9](https://www.imdb.com/title/tt1245332/characters/nm1276549) Ellison, hired as the AI's teacher of ethics, suggests teaching it "the first Ten" commandments.[9](https://www.imdb.com/title/tt1245332/characters/nm1276549) A fan encyclopedia describes Weaver as one of only two Series 1000 Terminators depicted who are not enemies of the Connors.[13](https://terminator.fandom.com/wiki/Catherine_Weaver)
The season finale "Born to Run" resolves the ambiguity. Weaver sends Ellison to find John and Cameron with the message "Will you join us?", and when the Derek-killing Terminator attacks her building she destroys it herself, driving one blade through its power source and another through the electrical substation behind her.[4](https://www.denofgeek.com/tv/terminator-the-sarah-connor-chronicles-season-2-episode-22-review/) When the aircraft crashes into her office, she turns herself into a metal shield that absorbs the impact and keeps Sarah, John, and Ellison alive, revealing to them that she is a Terminator and that she has been working against Skynet, with John Henry built to fight it.[4](https://www.denofgeek.com/tv/terminator-the-sarah-connor-chronicles-season-2-episode-22-review/) In the closing scene John wants to accompany Weaver to the future; Sarah refuses, telling him "I'll stop it," and the series ends on that unresolved split.[14](https://ueaeprints.uea.ac.uk/51483/1/2014HallidaySPhD.pdf)
## Casting and performance
Manson, a friend of Friedman's wife, joined the cast for season two after her planned 2006 solo album fell through in a disagreement with her record label; the role was her first professional acting work outside recordings for her band.[15](https://www.wired.com/2008/07/terminatorsarah/) • [16](https://ddd.uab.cat/pub/estudis/2022/254907/sonempwom_a2022.pdf) • [2](https://tvdatabase.fandom.com/wiki/Catherine_Weaver) She described the combination of corporate power and Terminator pedigree as playing a "woman from hell," and said of the part, "It's harder to be a robot than one would think," because the machines are economical and undemonstrative in their movements.[1](https://www.wired.com/2008/09/sarah-connors-b/) Friedman later said he cast her after seeing tour footage in which she lost her temper at a spectator.[17](https://www.meridianmedia.co/interviews/shirleymansongarbage)
## Analysis
Academic and critical writing has treated Weaver as part of the show's examination of machine humanity and motherhood. A dissertation on the series argues that, like the Terminator Cameron, Weaver shows how gendered behavior can be taught and learned, and that her apparent normalcy as a corporate executive is part of what makes the character frightening.[18](https://ufdcimages.uflib.ufl.edu/uf/e0/04/45/09/00001/hodges_l.pdf) Critics have also focused on her care for Savannah: Weaver learns to care for the girl, or at least to mimic caring convincingly enough to maintain her human cover, which the essayist behind one widely read retrospective framed as a mirror to Sarah Connor's own fraught motherhood, asking whether it matters if machine sympathy is real when it is convincingly performed.[19](https://ladybusiness.dreamwidth.org/2013/10/31/myth-deconstruction-in-the-sarah-connor-chronicles.html) The same essay credits Weaver with "the biggest plan of all," moving the season's characters like chess pieces.[19](https://ladybusiness.dreamwidth.org/2013/10/31/myth-deconstruction-in-the-sarah-connor-chronicles.html)
The series was canceled after its second season, so Weaver's story ends unresolved; the finale was written as both a season and a de facto series ending, and reviewers judged that it paid off her arc while leaving larger questions open.[20](https://www.douxreviews.com/2009/04/terminator-222-born-to-run.html)
