Thanks for your comments Danny.
It will be a shame if Jack doesn't return to Doctor Who at some stage. At least we can watch him in Torchwood series 2 whenever that arrives on screen. Early 2008 is what I last heard. It will be interesting to see how Martha is included with Torchwood and what her role will be? Will she take a holiday to Cardiff and just happen to bump into Jack?

That would be silly now wouldnt it.
