How to bring him back: Remember how Jack Bauer was originally piloting the plane before George Mason emerged from hiding at the back of the cockpit? Well, how on earth did Mason manage to suppress all the frequent wheezing and coughing that had blighted his existence since the plutonium exposure? The answer lies in the fact that his twin brother Jason, who has a bad skin condition, did a covert swap with George prior to boarding the plane. Brotherly love and all that. George has since found a miracle cure and has been living it large in Hawaii.
How to bring her back: Erm, bulletproof vest and more cunning use of blood capsules than an English rugby player? So what if her eyes were gawping wide open and staring straight ahead - didn't anybody see Robbie Williams on The X Factor recently? Nina was so good at deceiving everyone, so playing dead would be a doddle to her.
How to bring him back: It transpires that Bauer was in cahoots with his former colleague Saunders all along, with Chappelle only grazed with the bullet in a similar way to Renee Walker's fake death in Day Seven.
How to bring him back: Remember the film JFK? There was the whole 'magic bullet' theory about how the cartridge that killed Kennedy ricocheted around his head - hence the strange entry and exit points. Well, lightening can strike twice. So the bullet that entered David Palmer's neck bounced around inside him like some entrail-strewn pinball machine and missed every vital organ and artery. His death was then faked, using a secret emergency protocol known by his close family and colleagues, in order to keep him from any further assassination attempts. He currently spends his time playing online Scrabble with his brother Wayne.
How to bring him back: We only heard the explosion. Brave Benton might have hacked off his leg ('it's just a flesh wound!') and managed to keep enough pressure on the landmine's trigger mechanism by weighting his detached limb down with a few nearby rocks. Using a bit of string from his pocket, he ties it onto the fleshy stump and hops off to a bush to hide. When Juma's men come nearby, he yanks on the string and pulls the leg off the landmine to explode it. Oh yes, then miraculously a Red Cross van turns up with plenty of blood supplies!
How to bring her back: Give Kiefer Sutherland a bit of Botox to knock off a few years and have Jack Bauer stepping out of the shower and into the arms of his beloved Teri. You see, everything was just a dream. Come on, they did it on Dallas!
