Castiel's mouth presses into a thin line as he watches Dean's face, pliant for the moment as he is undressed.

He knows Dean does not believe in that future and he understands why but it does not change what he feels. He simply has faith in the strongest sense that it will happen. Dean will go grey and Castiel will fall and catch up with him and they will grow old.

"I don't know what's wrong with a rocking chair," he wonders aloud as he reaches out to tug Dean's jeans off his hips. "We could get a porch swing, instead. We could get over-sized, durable lawn furniture and have sex in it, as well."
