I think Lilith and Catherine look the same cause Lilith made Catherine on her own. But they're different people
Nope , it's not that , it is because of her answer, she said I m Lilith but for you it's Catherine something...the she answered make it like said I m "you"
oh I think maybe it's that they become "Lilith" when they take over the power? Cause Catherine is human...ish rn. But if she was to maintain the void she'd have the power of Lilith and become "Lilith" instead of normal Catherine
Like a title instead of a person
It's herself??
