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)
