By then, Nucky will be furious and put out a hit on her
While I think the scenario where she reports to Van Alden is plausible, although she strikes me as a 'slit my wrists or threaten the children' kind of crazy drama queen more than a clever snitch, I do not, under any circumstances, see Nucky 'putting a hit' on a woman. If one thing has been driven home again and again, it's that he AND Eli have a serious issue with people who abuse women. I don't see him as that kind of coward. I think Lucy will devise her own downfall. If Nucky were ever to hurt her, I think it would be in a panic over something where she forced his hand, not just assassinate her for threatening his business.
I seriously doubt he has ever confided in her about anything, either. Anything Lucy would know would be via witnessing, and she wouldn't fully understand it or have the info to dot the i's and cross the t's.
My bet is for her to go fully psycho on everyone and completely self-destruct. The difference between Lucy and Margaret is that Margaret is smart with her manipulation. She's intellectual, which is why she would go to the feds. Lucy is a wild creature, pure instinct and adrenaline.
