What is Rory anyway? Still plastic? In which case... if he's still immortal then how the hell is he having all these problems all of a sudden? I don't know about you, but if I'd survived thousands (?) of years, plagues, the Blitz, etc. then I'd be perfectly comfortable with a black mark because, well, I won't die from some Siren after my blood, I'm immortal and made of plastic. And after that, I won't die from water in my lungs, I'm immortal and made of plastic. You may sense a theme about to go on here.
