User blog comment:Tommy,Klaus&Kol2012+/what to expect in season 9/@comment-108.16.120.27-20130523041406

1. I doubt there is a way to close the gates of hell without the soul of the person being used, Naomi even said after gleaning into Metatron's mind that it was God's intention for it to be the ultimate sacrifice. The destruction of the person's soul, personality and body all together would close the gates only God would be able to close them without dying as the effect would probably happen to angels as well.

2. Crowley will probably go into hiding even though he might still hold his demonic powers, he doesn't have the will to use them against other people. There is also a possibility that he might become the power behind the Winchesters now since Castiel is now completely powerless due to his grace being stolen. As for Abaddon. . . there might be a mass cleaning in Hell by the time she is done with it.

3. As seen in the last episode of season 8, the drill is meant to dig into the minds of angels to either "reprogram" them or glean information from their minds to learn their secrets. Now you have something like that can pierce into an angel's mind imagine if it was suddenly lodged into their brain and still active? What would such a thing do for a mortal being? Its an instant kill, Metatron destroyed her brain and without it she could not live its as effective kill as the angel blade just in an unsual way. Also take into account that this is an angelic tool and it would stand to reason that not only an Angel Blade would work on them.

4. I don't think its about sealing up the angels and demons any longer considering that the angels are now on earth, powerless and human while the demons would be running around trying to slay them maybe. It would be hell on earth literally. The main focus would probably be trying to reverse what Metatron had done and return the angels to heaven, there is probably a section on the tablet that will tell how to do that since the spell weren't trials and there might be a way of undoing it.
