This week’s episode, “Regarding Dean,” was written by Meredith Glynn. The episode’s teaser focuses on the Winchester’s history with witches and it begins with Dean chasing a guy through the forest, an injured guy who is on the phone with someone. The guy tells the person on the phone to go. When Dean catches up to him, the guy is leaning against a tree. A sigil lights up the tree and the guy knocks Dean back.
Dean wakes up the next morning with a bunny nibbling next to him.
