Remember that bit in The Iron Man where the Iron Man chucks himself off a cliff? Maybe he falls, actually – I haven't read it in a while. Anyway, the Iron Man topples off this cliff – because he's sad, because he's a metaphor for the Cold War, or because life is so lonely and pointless that toppling off cliffs is the only smart thing to do – and when he hits the ground he smashes into hundreds of pieces.
Who wants to live forever? Not wise-cracking demon hunter Bryce, that's for sure. After 500 years on this mortal coil, he's royally bored of Abba tributes and Only Fools and Horses repeats. And there's only so many times you can listen to people whining about The Phantom Menace before you want to rip off your own head.
