Rowena annoys me. She will take over Hell or some crap. Her being around to mutter things and manipulate Crowley makes him seem like an idiot. Bleh, just bleh.
Oh. Oh, hey. Now THAT would be sweet. Especially since the musical ep casually mentioned that the brothers sort of left Adam in the cage, whoops...maybe they decide to let Lucifer and Adam out. Lucifer still needs a mortal agent, and of course Sammy would volunteer because He Can Control Lucifer Really and that way they could remove the Mark.Girl, dreaming.
As I watched this episode, I thought to myself, "Haven't we done the whole 'Sam tries to save Dean even though Dean is doomed' storyline in season 3?"
The only thing I can think of is that they're planning on using Cole for something important. (Please don't let it be a spinoff.) Because why the heck would they bring him back for such a crappy episode? Just to give his character a chance to say, "OMG, guys, I totes get you now?"
Now that we've set this all up, though, the next episode had better make some progress toward whatever move Sam is going to make.
Coworker and I have the season-ending ep all worked out: Dean kills Sam because of the Cain and Abel curse. Dean kills himself out of remorse. Cas heads to Hell to save them but finally gets fed up with their codependent angst. Instead, Cas finds Meg, rescues her from Hell, and they finally have that pizza.
For the last 2 mins before the credits, Lucifer returns, ganks Crowley and Rowena. Chuck casts Metatron into Hell and sits back with a glass of single malt, feet on desk, watching a rerun of season 1, episode 1.
