User blog comment:Mlgrsd/What do you thin, will somebody die in S12?/@comment-28192538-20160825140032

Well, I think Lucifer will never die.

Michael will be probably freed, or remains forever down there in the cage, along with Adam.

Crowley will be probably die in S13.

Cas will never die, of course already, but Chuck will bring him back.

Dean and Sam could probably die, but they will banished in the Empty.

Gabriel returns, or remains forever dead.
