One day, Dean is going to catch onto the fact that when he’s near Cas – close enough to touch and wanting to touch then suddenly feeling relief despite that nothing physically changed – he’s being caressed by a wing.

He’s being touched by a powerful wing that can move mountains, span the height of a skyscraper, and kill in a deadly swoop; but, Cas uses it to comfort.

Another day, Cas will realize that Dean feels it when it happens and welcomes it.
