ya see I'm of the opinion that we'll never know whether utopia is real or not, and persoanlly I'm quite happy like that...... and I reckon the master can't know *for sure* seeing as he's the first time lord to come forward this far......
anyway after wathching the episode I figured that the doctor was doing something to the tardis with the screwdriver which would make it return to him, it was only after someone else pointed out the capt'n jack watch thing that I was converted to that idea - BUT the watch can only travel through time and they ain't on earth anymore...... (watch as this is forgotten about)

re: the masters plan. I'd assumed that the master hadn't had a choise in his prediement, that someone/thing had humanised him and hidden him at the end of time (boe maybe) which would be why he has no tardis of his own and stuff - if boe did this (he could have humanised him and send him forward in time expecting to live that long until gridlock happened), it would explain boe's "you are not alone" equalling yana as a name

I'm guessing that a time lord dying as a human would mean death, otherwise the family of blood would just have killed john smith in order to get they're hands on a time lord

as for jack - to me is seemed like he wanted adventue and to live the life of the doctor's companion - this is why he said he used to want to die and now he wasn't so sure - being on an adventure with the doctor had brought him back to heath.....

my understanding of the second series of torchwood is that while jack will make appearances, he won't be in all of it - personally I hope he stays as a companion - he makes a much better supporting light-hearted character than serious leader
