Like I said, the real solution here is "Sign on with the Unseelie Accords", Marcone managed to get on those, and it's functionally a mutual Non Aggression Pact between signatories tied in with diplomatic credentials and channels, and Marcone showed that they are flexible, all you need is the balls to try, and the might to succeed, given how he got there based entirely on money and influence rather than any arcane power. Molly is--technically--the reigning Prince of a Hell, even if she can't access it yet, she has territory. It means the White Council can't just declare that Molly is a rogue Warlock who needs to be executed without triggering the mutual defense clause. It even satisfies the hardliners because the Unseelie Accords also limit how much bullshit Molly can do in turn, it's a compromise candidate, but it merely requires audacity, rather than getting anyone threatened with getting their head cut off.
