 Teasing John 's role in " Exit Wounds " Marsters stated that he 's someone " who 's in way over his head and doesn 't even know it yet " and that " things do change " in regards to his character . Chibnall , Marsters and producer Richard Stokes discuss the role of " Exit Wounds " in developing John 's character and placing him on a redemptive path . Marsters felt the character to be on a " journey " whilst Chibnall deliberately played upon the question of " can you trust him , or can 't you ? " Stokes commented that the character isn 't the " selfish and anarchic " character seen in " Kiss Kiss Bang Bang " and that his " affection and love for Captain Jack are enough to make him try and do the noble thing " . Stephen James Walker , a writer of reference works on Doctor Who and its spin @-@ offs , notes that because of the reluctance of Hart 's collaboration with Gray and his remorse for his actions the episode leaves the audience " a little more favourably disposed " towards the character . In April 2008 Marsters indicated that he expected to return to Torchwood in the near future . He later expressed a desire to be part of Torchwood 's fourth series after it was revealed the show would be largely produced in Los Angeles .
