So something I havent brought up yet but im sure will, but how do you think they will work around jack killing chuck? Cause we've been told chuck is needed to keep the universe around or it will unravel and die.
My best guess is it will be an unlinking spell as part 1 of killing him, to unlink chuck from his own creations but like wouldnt this mean he would have created a spell to do this unlink? Like that doesnt make alot of sense to me. Then again there were spells to kill beings who had never died, like the pagan gods had lore how to kill them despite only being one of their kind. Plus it was revealed there is a spell that can trap away chuck himself and amara but we've been implied chuck is the one who makes all the rules yet some greater force is saying he has weaknesses. So again we run into this problem of is he omnipotent or not. And he is watching them 24/7 so he knows jack plans on killing him.
Plus even if chuck died, something tells me with the multiverse of winchesters, there are other copies of chuck out there as backup copies, i could be wrong but maybe im not.
