He is our favourite con man, chancer, charmer and flirt. Omnisexual, openly lascivious and a man who has men, women and aliens falling all over him. He has, quite literally, shagged his way around the universe and charmed his way out of trouble. He made us laugh in Doctor Who; he was a fine leader in Torchwood. I believe that nobody will ever forgive Russell T Davies for the events in Children Of Earth. I'm sure that I wasn't the only one who had their heart torn out, stomped all over, ripped to shreds and repaired just for it all to happen again. There have at least been references to Jack since Matt Smith took over as our beloved Time Lord. Not least the scene where Dorium Maldovar is selling River Song "A transportation device, fresh from the arm of a Time Agent". Well, we only know of one Time Agent, don't we? A former Time Agent perhaps, but he still refers to himself as such. We also know that you could chop his head off and it would grow back. Let me get one thing straight here: I love Jack; I would love to see the character in Doctor Who again. I would love for this to happen but I don't believe it will, and here are my five reasons why.
