It would seem a little redundant to do the Wallace thing again where someone tries to leave the life that could potentially kill them only to discover that their "need" for it is worth the risk. And it would be redundant to have Abby get burned twice by a prostitutes that she tried to save.

Certainly I think that's the last we see of her this season. They might be able to pull it off down the line, but doing it now would be lazy storytelling.
