Dean yelped obligingly and glared at Sammy, telling him that this all his fault and that he’d get his revenge. “Just you wait! It’ll come when you’re so not expecting it and it’ll be brutal. Bank on that.”
He took the painkillers he was offered then raised an eyebrow at Sam. “Hey? You think you can get gangrene in your head? That’d be something. Maybe the zombies wouldn’t wanna eat you if you had that.” He glanced back the TV where a particularly speedy zombie had caught someone and was busy hauling his innards out. Dean cheered and grinned happily. “Don’t ya just love these movies? I can’t understand why you don’t like zombies.” Even without the demon blood thing, Dean always thought that Sammy was a different species.
