User blog comment:Tommy,Klaus&Kol2012+/Were the shedim confirmed or even hinted to appear in the final season at comic con?/@comment-4554525-20190723145945/@comment-4554525-20190724053015

they werent fully part of his backstory, they were a means to an end for him

and lucifer aint dead and gone, he is locked up and almost came close to coming back, if the writers were smart here, they'd use this to their advantage in a cool nostalgia way.

the whole point of bringing back old characters and fan favs is not just to say hi, im here, im back, its to do things with them, its also serious foreshadowing if lucifer gets released and goes bad or maybe the shedim come out and the boys try one more shot to get lucifer on their side and tell him to face his fears

i mean, how often do you hear of the devil, the actual devil being afraid of someone or something?, he isnt even afraid of god, he mocks god if anything, this is too good of a shot to pass up
