oh fuck what if his little brainwashing trick worked on him, doubt but that would be so good from an angst perspective

only s1 was basically about that. sinners can hurt angels when correctly equipped.
carmilla is making something for vox, she makes the angelic steel weapons that won them the war i bet whatever she's making is how vox is gonna capture and use lucifer

and it has been established now that lucifer cannot harm sinners which i'm guessing it didn't even cross the minds of heavenly beings he might need self so i doubt there's a loophole for that bc a sinner harming an angel, even a fallen one, why that could never happen
