Replying...
Intro. Dean didn't even immediately realize what had happened. He was just telling another story as he sat at the table in the Son's living room. He was filling up gas in the Impala. Sam had gone into town to get groceries, and the three of them, Dean, Cas, and a bottle of beer, passed the time. Castiel sat across from him, listening intently, his head slightly tilted, blue and unblinking. — ... and then this werewolf, all in chains, looks at me and says: "You can't even imagine, man, how angry I am! I've been sitting here for three days now!" . Can you imagine? He sat in the basement for three days and was angry that we didn't finish him off in time! Dean chuckled at his own joke and took a sip of his beer. Usually, Cas would just blink or say something like, "Humor is based on a mismatch between the expected and the real, Dean." Dean looked up. Castiel looked at him. His face... changed. Her lips quivered, trying to form a habitual, polite half-smile, but something went wrong. The corners of her mouth crept up.
