He came along with The Doctor and Rose to the present of Lifelines to help Otto.


Captain Jack Harkness is a fictional character played by John Barrowman in Doctor Who and its spin-off series, Torchwood. He first appeared in the 2005 Doctor Who episode "The Empty Child" and reappeared in the remaining episodes of the 2005 series as a companion of the ninth incarnation of the series' protagonist the Doctor. Jack became the central character in the adult-themed Torchwood, and returned in the 2007 series of Doctor Who, reuniting with the tenth incarnation of the Doctor, and again for the 2008 series and a 2010 special.

In the programme's narrative, Jack begins as a time traveller and former con man from the 51st century. In contrast to the Doctor, Jack is a man of action, more willing to apply a hands-on solution to a problem. As a consequence of his death and resurrection in the 2005 series finale of Doctor Who, the character becomes immortal. On Earth, Jack becomes a member of Torchwood, a British organisation dedicated to combating alien threats, becoming its leader over a century later. An ambiguous backstory is gradually revealed in the course of both series, adding another layer of complexity to the character.
