So I'm thinking, what if the Fae Queens from ToG are actually the human queens from ACOTAR after being in the cauldron? Because Mab and Maeve sound like the light and dark queens from ACOTAR.
Oooh that’s a good theory! I could definitely see that happening, although I think Sarah commented that she wouldn’t cross the two series’ over though :(
I actually have my own theory about what will happen when the mortal queens go into the cauldron. I think the cauldron takes a human’s character traits and emotions and amplifies them. The cauldron amplified Elain’s beauty, which was perhaps her most defining trait (as you can tell I don’t have a very high opinion of Feyre’s sisters). When Nesta was made, the first thing Feyre notices is the“ Rage. Power. Cunning.” in her new being, all major traits from her fiery human self that were amplified by the cauldron.
I think that since the Queens’ dominant character traits (greed, spite, betrayal etc.) are all negative and horrible, they’ll end up as monsters after going into the cauldron. The cauldron will amplify their ugly characters, and hopefully we end up with some new horrible evil creatures for Feyre to squash :)
