Although she wasn't alone in having used Torchwood-acquired technology to her own advantage, she had been the most destructive.
Little is known about Costello's personal life or upbringing, save that she loathed her father and had an affair with Owen Harper. When she joined Torchwood Three she was on the run and had wiped her files clean. She placed triggers on Pilgrim member Max, using retcon that would lead to her resurrection with the resurrection gauntlet three months after her death. (TV: They Keep Killing Suzie)
She developed a nihilist worldview from aliens such as Weevils coming through the Cardiff Rift and found murder as acceptable a means as any for achieving her goals, particularly to unlock the secrets of the resurrection gauntlet. The gauntlet worked particularly well on the victims of violent deaths, (TV: Everything Changes) and more so on injuries inflicted by the life knife. (TV: They Keep Killing Suzie) In 2007, Costello committed a series of murders with the life knife to improve her use of it. She was discovered by PC Gwen Cooper. Her attempt to kill Jack Harkness in her escape was thwarted when Jack's immortality was revealed. Suzie took her own life. (TV: Everything Changes) This was another step in her plan to revive herself. Costello's body was placed in the Torchwood cryo-chambers and her worldly possessions collected and placed into storage as was common practice for deceased Torchwood operatives.
Three months after her death, Max committed murders, marking corpses in blood with the word "Torchwood" to draw Torchwood's attention. After discovering her involvement with Pilgrim, Torchwood decided to revive Costello, ironically with the very resurrection gauntlet that Costello had killed for earlier. Gwen wielded the glove this time, but rather than reviving Costello for only a few minutes as usual, the glove revived her apparently permanently. This left Torchwood in a quandary since they now had a dead person who had come back to life, yet among other things still had a severe head injury caused by the suicide bullet. Unknown to the team, Costello had foreseen this and through a mental link in the glove, Gwen was forced to transfer part of her essence, which Costello used to heal her injury, an action which slowly killed Gwen.
Seeing the effects on Gwen, Jack asked Costello to give up her restored life. She refused. Faced with Gwen's imminent death, Jack shot Costello down in cold blood. However the link via the gauntlet prevented Costello from dying. Only after Jack ordered Toshiko Sato to destroy the gauntlet did Costello die again, this time forever. Her body was returned to the cryo-chamber. (TV: They Keep Killing Suzie)
Following the destruction of the Hub, a piece of alien technology concealed within her body was activated, enabling Suzie to be resurrected for a third time. After murdering one young worker at the site, she fled the area, undertaking the alias Sue Costa. A series of brutal murders followed until Suzie was finally tracked down before then being enticed back to the hub. There she met DCI Tom Cutler with whom she had previously shared an intimate relationship. Tom attempted to negotiate with Suzie before the hub was destroyed a second time. Half an hour later the two were locked in each others arms before the explosion took both their lives.
Behind the scenes Edit
- In order to catch viewers unaware with the twist ending of Everything Changes, the first episode of Torchwood credited actress Indira Varma as a regular cast member. She was featured in pre-broadcast publicity for the series.
- In his book Doctor Who: The Writer's Tale, Russell T Davies reveals that he planned at one point to bring Suzie back for an episode of Series 2 of Torchwood.
