I still want to know what Sam was doing when Dean was off getting his hickey.

Dean was mocking/teasing him about sitting at home in his Snuggie watching 50 Shades on Netflix and Sam just looked at him and said, "Yeah, no." and moved on to the case. WHERE WAS HE? WHAT WAS HE DOING? Was Jason Momoa involved? I need to know these things! For science. Purely for science.
