no but the night after naomi is killed
dean taking cas back to the bunker
asking him to stay a while
cas sitting in the chair, watching over dean while he sleeps
until dean turns over and says “you can come lay down, if you want.”
and cas does
and after a while dean puts an arm around him and whispers “I’m glad you’re back”
and cas would stay like that all night, watching dean curled around him
and its the best night of his exsistence
