Echoes

The Winchesters somehow get always into problems. This time is not different. Dean is affected by a kind of spell, a de-aging spell that is not like the others, one spell that is going to give Sam a lesson about the feelings of his brother. Because -as Pink Floyd said- the echoes of distant times will come willowing across the sand. They have to find a way to meet in the sea and see, because the echoes of the past resonate in the present.
