citrusjava | Messy Finale speculations (please no spoilers!)

So the way that makes most sense to kill Crowley is for Dean to do it - and that would work, because it wold put in motion both Rowena maybe working to remove the mark (the 'personally' thing sounded interesting) and the prediction of Dean killing everyone he loves.

My money's on them handwaving (heh heh) away the concept of the mark still influencing the person even if removed. I doubt my speculation about Metatron using the tablet to control Dean will happen at this point, though maybe. H emight become ruler of hell if he can't become ruler of heaven.
Would be kinda cool if Rowena wanted the mark, but that'd just give them another redhead demon bad gal.
I suspect she'll want something handwavy, and that we might still get some Olivette - maybe.

I doubt we'll get another serious "will Dean kill Cas". Also, I'm kinda uncomfortable with Cas being the Winchester killed for the finale - it's a territorial thing!

I have horrific ideas of Sam taking it on and killing himself/becoming king of hell
