With the War of the World being nigh, I still think the Shedim will be released, but on purpose, to fight against the invaders. Likely the monsters from The Bad Place as well.
Jack might be able to restore the angels' wings as well, but I don't think he can make more. If he can, however, I presume they won't have broken wings like the others.
S14 will probably involve hunting down the Shedim and the monsters from The Bad Place.
I'm talking about the usual "Big Bad shows up for the first few episodes, goes off the grid even though it should be physically impossible for it to do so, shows up mid-season, disappears again, and returns during the last 2-3 episodes for a big finale". Jack could have been kept around in the bunker, training his powers. No need to make every episode about him, just give him something to do instead of having the Winchesters calling up hunters (again) that find nothing (again) even though Jack is an inexperienced Nephilim whose power is so great, a Prophet who'd met God thought he WAS God. He doesn't know how to suppress his power any more than he knows how to control it, and yet we're supposed to believe he can just hide?
I like this serie…
The Shedim will be released, but Sam and Dean will find a way to stop them. However, they don't sleep in the Empty like regular demons, due to their savagery, and begin waking up other demons in the Empty. The Cosmic Entity, wanting to sleep once more, unleashes a horde of demons upon the Earth that would dwarf (hypothetically) opening every Devil's Gate on Earth simultaneously. Amidst all this, Jack goes bad, but is redeemed. Then, I'm guessing, the Cosmic Entity becomes the new Big Bad, and Jack is the only hope they have of stopping it.
So, Michael says he took care of Lucifer "in a way most people could never understand". I think this refers to the time when Lucifer received the Mark and was corrupted, similarly to how Sam took care of Dean (or tried to, anyway), to keep him from falling under the Mark's influence.
Thoughts? Aside from the obvious "Mark of Cain/Amara hadn't been thought of at the time".
So, we all know God created the Leviathans, then locked them away. However, why did he even create them in the first place? Surely he knew that creating cannibal beasts wouldn't work out so well when they discovered humans were tastier. So, here's what I think:
"Bone of a righteous mortal as light and good as the Leviathans are hungry and dark."
"Come on, Daniel, you know the stories as well as I do. All-powerful. All-consuming."
"God was the Light. I am the Dark."
I think God created the Leviathans because he regretted imprisoning his sister and wanted something similar to her. Is it a coincidence that a Leviathan's true form is a pitck black substance, or that they consume everything in their path? Maybe. After all, season 11 hadn't been tho…
