Didn't Vriska say something about how angels were evil and John replied don't you mean demons, and she said something akin to "same thing'?

English IS referred as the Angel of Double Death too, and both Jack and PM are powered up exactly the same but do evoke a Demonic vs Angelic duality. I can’t quite recall about Vriska saying that, but like, there may be something fun to look into there.

When it’s not 4 AM at least.
