walk away, for the Doctor, everybody lives (if he can make it happen).  Even this one man. That's the point when The End of Time finishes.  Or at least when the Doctor heads off in the TARDIS with his regeneration expectation.  After that we're into an epilogue, the deliberate epilogue.  Like I said, functionally it's not doing much more than the close of Journey's End , it's an indulgence.  But why the hell not?  If The Lord of the Rings films can have a dozen endings after nine-twelve hours of screen time (depending on which version you're watching), the Russell T Davies years probably deserve an extra twenty minutes, the Doctor holding back his regeneration, if only to explain why Mickey and Martha didn't join Torchwood after all. Oh there they are in their own gun-toting spin-off, married, the Mr & Mrs Smith-Jones of the Whoniverse chasing aliens in an industrial power plant straight out of the Pertwee years.  I can't be alone in thinking at some stage this would have looked like a more palatable spin-off than Torchwood though I can't help feeling sorry for Thomas Milligan who she's clearly turfed over in favour of the more exciting life.  Was it like Brief Encounter but with Mickey's uzi and bug hunts rather than shopping and trips to the movie and a Weevil instead of Dolly Messiter?  Noel Coward wouldn't have stood for it. A wink towards The Sarah-Jane Adventures .  Something else entirely towards Torchwood .  In his diary
