Holding cells (Torchwood Hub)

The holding cells referred to a room of prison cells within the Torchwood Hub. They were used to both contain and quarantine dangerous creatures and individuals. The cells could be opened and closed through use of a swipe card. (TV: Day One) While they were mostly used for short-term containment, there was one long-term resident: a Weevil which Jack Harkness named Janet. (TV: Day One, TV: Combat) Janet had been captured shortly before Gwen Cooper joined Torchwood Three. (TV: Everything Changes)

Carys Fletcher was briefly kept in a cell while she was possessed by the Sex Gas. She was able to escape by exerting her influence over Owen Harper, allowing her to take his swipe card. (TV: Day One)

Jack noted that, as they were mostly made of liquid, a captive Arcan would make a mess of the cells. It was partly for this reason that he felt it better to simply warn off the crew of an Arcan leisure crawler rather than attempt to apprehend them. (TV: Cyberwoman)

Ianto Jones pleaded with Jack to let his girlfriend, Lisa Hallett, stay in the cells; Lisa, having been partially converted into a Cyberman, had attacked the team. Jack refused and ultimately led the team in killing her. (TV: Cyberwoman)

Max Tresilian, a pawn of Suzie Costello, was taken to the cells by Torchwood. (TV: They Keep Killing Suzie)

When Torchwood was trying to find the Weevil Fight Club, they let Janet loose and used her telepathic senses to find other Weevils. Janet almost killed Owen before being recaptured. Following his ordeal, Owen stood outside the cells, where he successfully intimidated Janet and another captive Weevil. (TV: Combat)

After the Cardiff Space-Time Rift fractured, a temporally displaced Roman soldier was captured and taken to the cells along with multiple Weevils. By this point, the Hub was full in all vaults across all nine levels. Jack gave Ianto his approval to activate the vaults below, which Ianto noted had never been used since he joined Torchwood Cardiff. Outside the cells, Ianto encountered an apparition of his dead girlfriend, Lisa Hallett, who told him to open the rift.

Later, Gwen forcibly took her boyfriend, Rhys Williams into the cells for his own protection. However, Rhys' cell door spontaneously opened. Stepping out of his cell, Rhys met Bilis Manger, who stabbed him to death. Rhys' body was soon found by Jack and Gwen. When the Torchwood team opened the rift despite Jack's warning, both the Roman soldier and Rhys' corpse vanished while the Weevils went into a frenzy as Abaddon arrived. After Abaddon was killed, Rhys reappeared at his home, with no memory of being detained or killed. (TV: End of Days)

Beth Halloran, a sleeper agent of Cell 114 was briefly brought to the cells by Torchwood. Whilst there, Janet visibly cowered in her presence. (TV: Sleeper)
