I like to think we can get Michael back.

I do agree that Lucifer will get to possess Sam, and maybe Dean will say "yes" to Michael, but I don't think Castiel is strong enough to substitute Raphael. The power difference is just too great.

I like your opinions. I mean, they might lock Amara up again in some place where escape will truly be impossible.
