Ooh, yeah, I’ve seen a few mentions of it but not much speculation. Crowdsourcing might be best, aside from your teen Netflix show expertise, I know nothing about this either.
I will say, though, that when that was brought up in an interview with Simon Barry, and I think it was the VIFF one, he didn’t seem to really indicate they were building up to something significant with the name. He was just like, oh, we took the name from the comic character and her origin story there was that she was half-demon already, which is what we’re seeing our Lilith kind of become, gaining these powers and even the silver hair. He already seemed to be looking ahead and at a different story. So I don’t know if it’ll go back deeper than that, it might just be religious names scattered throughout. But who knows, maybe he was just disassembling, or maybe that person asking the question is what now made him think about how to use that. I don’t even know who Lilith really was, how she could be referenced, so maybe there’s something I haven’t even thought of.
