Excellent episode, loved it. Funny & touching. I wouldn't have minded at all if they had made this the series finale episode and had Sam/Dean driving away into the night as the final scene.
Mourning the disappearing usage of the -ly suffix. Words being cut-off before they've had a chance to fully form, left incomplete, with their shoelaces untied and their zippers undone. If I quote your post (or post in your thread) without comment, please check your zipper.
