Jack Harkness's mischievous fellow time agent Captain John Hart could, at some point, make a comeback. Buffy and Angel star James Marsters told MTV that, if asked, he'd like to make a return to the show. The actor who has played a number of cult characters in his time listed Torchwood along with Buffy and Smallville when asked which show's universes he'd like to make another appearance in. He was rumoured to be in the upcoming third series before it was later announced to be a week-long five parter. Marsters was at a recent event for his latest project Dragonball: Evolution when he made the comments. His character was last seen in the hub during the series two finale.
