A great start for the last season.
First, the song choice of "The Famous Final Scene" by Bob Seger... excellent choice for THE ROAD SO FAR. And I loved how it still played in the teaser, all the way to the title card. I will confess... knowing how much Dean loves Seger and how the song was so perfect for the last season, I already shed a single man tear while it was playing. Very much the same way with season 6's "EXILE ON MAIN ST."... not only was it perfect for Dean's situation at that time, but it happens to be my favorite Seger song. And yes... I shed a single man tear when that originally premiered, as well.
Next, we got to see some VERY old defeated foes... the woman in white, Bloody Mary, and that damned clown. (This is precisely why I find clowns supremely creepy.) I think that other woman ghost, the one wearing black, was Margaret Fox from season 7's "THE MENTALISTS". Not sure who the guy was... I'm going to have to think hard on that one.
And interesting having that demon take over Jack's meatsuit. And I find his reasons for helping the boys strangely understandable. I guess even in hell, some people don't like change and just enjoy going to work and doing what they are good at. And I think the rock he was referring to is that really old one in England... Rudson Rock or something, which is like 10,000 years old. And given his knowledge of spells, I wonder if he knows even more than Rowena.
It seems clear that this season will sort of be the epilogue of the boys' journey... did they really make a difference? Was it worth it?
And I caught that look on Dean's face when Belphegor said even the Cage was opened. Even crippled, as Chuck said back in season 11, Michael is still an Archangel. And damned powerful. Actually... he's the only one left. I think Dean is scared he'll escape and find a way to make him say yes.
And it looks like we'll finally get to see Adam this year.
So much to do and tie up for a 20 episode season
