Time Agent

Time Agent was the designation of individuals who worked for the Time Agency. One of the Doctor's friends, and sometimes companion, Jack Harkness was once a Time Agent.

Captain John Hart was a former partner of Jack Harkness during their time in the Time Agency, both professionally, and sexually. During their time in the Agency, Hart was trapped in a two-week time loop with Jack for a period of five years. While briefly arguing over who the "wife" was in the relationship, Hart agreed that he had been "a good wife, too". (TV: Kiss Kiss, Bang Bang)
