As far as the brother's plotline I loved it. At first I was sooo pissed at Dean. I wanted Sam to punch Dean in the face. He was being such a dick. But I Loved what Sam said when he stood up for himself. How he told Dean 'Hey you're the one who asked me to come back." I was also extremly happy that Dean finally admited to his part in starting the apocalypse. So I was definitely pleased with the ending.
But honestly the episode on a whole was meh. Maybe a 5/10.
Does anyone know how long the show is going to go on hiatus?
