Rupesh Patanjali

Rupesh Patanjali was a doctor, originally from the Midlands, who worked at the A&E department at St Helen's Hospital in Cardiff. Jack and Ianto encountered him while they removed an alien Hitchhiker from within a patient. His interest in Torchwood piqued, Rupesh tracked them down to the Bay and Gwen talked with him at length.

However he turned out to be working with the government and shot Jack Harkness so he could be restrained and a bomb planted inside of him. He was later shot by Agent Johnson in the back while trying to escape. His original plan was as to be planted as an MI5 infiltrator, to be hired and to get information on Torchwood from the inside. (TW: Day One) His body was then taking to an MI5 compound. When Gwen Cooper and Rhys Williams went to rescue Jack Harkness from the same compound, they found his body. (TW: Day Two)

Behind the Scenes
BBC promotional materials and early in the episode itself it looked as if he was going to join the team as a replacement doctor role since the death of Owen Harper in a similar way to Suzie Costello.
