Not having read the series, TJT explained a lot of what I was going to say my assumptions were. Also, his "family" is obviously just every other angel, and God is father to all of them, so it isn't like a "family" in the way that it seemed Tarrant was saying it. I could have misread the intent though, so my apologies if that was obvious to you.
Having done a LOT of research into angels and their "mythology" because it fascinates me and I've always wanted to write a book with those elements, it should be as TJT said that Lucifer is second only to God, with only archangels like Michael and Gabriel being even remotely close (everyone else so far down the power curve as to be inconsequential) and anyone else should know that. Perhaps this mythology is slightly different, or the removal of his wings has weakened his powers, or maybe that black dude angel is just a dumbass and doesn't realize who he's fucking with, but I fully expect that at some point he pushes Lucifer too far and Lucifer shows a fraction of his true power and leaves him a sobbing mess. I hope, at least.
I also like the whole free will question being a main focus, because I greatly enjoy this Lucifer who isn't inherently evil, and actually cares about people like that singer chick, but also doesn't give a fuck about being polite. I actually quite look forward to the little girl (Trixie is a hooker's name) growing on him and him reluctantly caring about her back. A "human" Lucifer is far more entertaining than a purely evil omnipotent being.
Why does this have to be so fucking far away?? Fuck. This is probably my most anticipated new show right now.
