Dean had to pause his eating for a moment to listen to what Duma said. Did...he need guarding? Was it that bad? He could remember the angel who ended suffering by killing people, how the jerk wanted to kill Cas, and probably would have if Dean hadn't come around and snapped him out of it. The bite went down hard and felt like it sat in his throat. They weren't that bad, were they? "Me? I think I can handle myself. Cas, too, when he's not distracted."
Whatever dark hole his thoughts were climbing down into got pushed aside for a look of pure confusion, maybe a little bit of disgust, maybe even pity. The hell was Duma doing? Dean had seen his share of weird eating habits but none quite made his stomach clench in fear like that had. Angels were just weird. This meal was starting to get worse by the second. "I don't know." He shrugged, staring at his burger. It was good. No point in not eating it. "I barely know you?" He offered, having another bite and chewing thoughtfully.
