"Dean, where are the burgers?" is a seemingly innocent question if looked at out of context, but a death sentence for the occasion, in Dean Winchester's mind. Let's say it's his one year anniversary of being in a relationship, where the they not only celebrates being together, but being alive in general. Also assume that this event was planned, very well planned because his significant other went through the trouble of researching it. He researched to the point that his boyfriend's brother's computer came down with multiple viruses. The plan was that Dean would bring the food, and Cas would bring everything else. Dean brought pie and beer.
"You just said food." Dean stated slightly irritated. Castiel huffed out a breath of annoyance and disappeared, leaving his lover of one year in a panic. Dean was worried to say the least, thinking things like, was Cas really so upset about burgers that he would leave? Would they break-up? Never speak again?
"You know, I don't like McDonalds as much as I like yours, Dean, but it will suffice." Cas said once again showing up quickly on the blanket he had laid out. He patted the spot next to him on the red checkered mat for Dean to sit down, which he did after swallowing down his doubts. He reached out for the burger, silently asking his partner for a bite to which his response was a slap on his hand.
"Don't get me wrong, Dean Winchester." The angel whispered darkly in his ear "You had one job and you failed, and for that, later you will be punished."
