Season 10: How to train your demon
¨Sam has tunnel vision about this. He just wants to find his brother.¨
Robert Singer, season 10 sneak peek on Vimeo.
"We come into the story roughly four to six weeks after we left. Sam only knows that Dean somehow disappeared from the bunker … the last time Sam saw him, Dean was dead and he certainly doesn’t know that Dean was a demon.” (x)
