"Finally." Dean sighed contentedly, staring at the food in front of him. "Do you know how long it's been since I've had one of these?"
"Well, you've been behaving yourself, so why not?" Sam smirked, glad his brother was showing signs of improvement. "Dig in!"
Without further ado, the eldest Winchester picked up a fry and tossed it in his mouth. Suddenly, he retched and spit the thing out, tongue smoking. "It burnt my tongue!" Dean yelped, looking at his reddened tongue.
"Salt..." Sam nodded knowingly. "Because it's a symbol of purity and you're a demon, a most impure thing, it only makes sense that it would-"
"I don't care why it happened, I care that it happened!"
"Try your burger, maybe it's not salted." He watched Dean intensely as the demon took a hesitant bite and then spit. "Nope, it's salted."
"Sorry dude. That's life. You should've ordered a salad, like me."
"That's rabbit food, Sam." Dean pouted, still rather upset he couldn't eat his favourite food.
