User blog:Epakrios/Plot holes

I created this blog in order to collect all opinions about the show's plot holes from all seasons.

In my opinion the show must explain better the hierarchy of Heaven and Hell. About Heaven, they must determine if every known angel we have seen is a Fiery(Seraph in hebrew), Rit Zien(I call the Powers as this is their true name in the lore), Guardian(regular angels) or of the other 6 classes. About Hell I would like to known where Azazel, Alazstair, Crowley, Cain and the Knights of Hell stand in the hierarchy and Astaroth also(his name should have been said somehow in the show).

How Eve, dieties and fairies were created?

Why the angels true form looks like a grace? Does it look like that because of Metatron's spell?

Bartholomew and Malachi play an important role in season 9. Why they have appeared only in 1 episode each? If their actors cannot play them anymore, they must find at least another vessel for them and explain that change in  the story somehow.

Who are the 5 creatures in the universe that the Colt cannot kill. Did Lucifer mean 5 species or 5 individuals?

These are my thoughts for the time being and I would like to see more from all fans.
