@drizzellla What do you bet, that if Lacey really does have a new boyfriend, he's a feeder. She wants someone to wait on her and enable her.
While I thought Lacey's ex-fiancee's sister was unnecessarily cruel to Lacey, she could see what was happening to her brother, who has medical issues and clearly some cognitive challenges.
She mentioned she has power of attorney for the brother's care. She seems to love her brother and is taking her role seriously for his protection. But, we can't rule out that there are secondary gains for her, too, that could become problematic with him marrying.
However, I can see why she wouldn't want to take on the care and responsibilities of another person, particularly one who was a user, and not investing in their own care.
All said, it was hard to watch this group of dysfunctional individuals, each struggling with their own complicated issues. It was a train wreck.
I hope that they have a follow-up with Lacey at some point. It was left leaving viewers far too uncomfortable.
