User blog comment:CROWMETA13/Can Lucifer beat darkness?/@comment-26855072-20160122220827

What if is there some other way to bind her, some blade or will be fight The Darkness vs God+Michael, Lucifer and maybe Gabriel.

What if will be revealed something about Gabriel. Maybe he tricked Lucifer as he tricked Sam and Dean. I think that Lucifer will stab and kill Amara and in next season Big bad will be Lucifer in Castiel's body and Gabriel will be replace Castiel.

Another theory:

In finale of  season 11 Castiel will beat Lucifer as Sam did and he will use his powers to beat Amara or will stab himself.

Theory #3

Gabriel is alive and will tell them every about Darkness in last eoisodes.

But there is another big question.

What will happen with Crowley. My theories:

1. Lucifer smite or kills kim

2. Winchesters summons him just in a moment.

3. Lucifer let him alive

4. Lucifer makes deal with him: Crowley must be on Lucifer's side
