You may want to see a doctor about that, Fya. XD
I dunno if I'm happy about another season. I kinda liked season 5's conclusion when it was going to be the series finale, and I thought the current storyline this season would be a great final season story as well. Don't get me wrong, I'm not wishing for the series to be cancelled or anything, I just would rather it reach an acceptable conclusion rather than overstaying it's welcome and getting canned mid-season. Or worse, having a lackluster series finale.
But since we are getting another season, I'm glad Cass will be there in a greater capacity. I'm curious if he'll be similar to the Cass of the alternate 2014 Dean saw once.
