'Torchwood,' which follows the adventures of a tight-knit team fighting alien threats, has gone through a lot of changes over the years, but two things have remained constant: Captain Jack Harkness and Gwen Cooper.
The new season of the compelling sci-fi drama, which arrives this summer on Starz, may be the biggest departure yet. Much of the show's fourth season is being shot in the United States, and the events of 'Torchwood: Miracle Day' will transpire in various locations worldwide.
Gwen and Captain Jack will both be back, but their lives will be different. Gwen, for one thing, is a "mum" now, as actress Eve Myles explains in the video below.
