One line from the report says:
Returning cast members include John Barrowman who will be making an appearance in the series finaleThat's it, an appearance? Hmm, which sounds like the first 11 episodes of the 2007 season will be Jack free. Of course it is expected that the Doctor would want Freema all to himself for a while, but I think JB fans were hoping for the Captain to be a companion for at least the last half of the series.
So, after Torchwood concludes this December, Captain Jack fans will just have to wait until July 2007 to see him again. But of course the BBC have never been misleading with any of their Doctor Who announcements in the past have they?
