She was sold off like Louis. Solid family, as solid as any that buys children off the street. Well-to-do, I'm guessing from her willingness to engage in conversation, polite, even if she doesn't want to, with a near stranger—one she knows is a cop. Feels isolated from you and yours, her "real family," like she doesn't deserve to belong, or even if she did, she could never fit. She gets defensive fast which speaks to insecurity. Thinks of herself as weak.
Did something she feels bad about and is blamed for by your family, [...] something centering around you. She tries to convince herself she deserves all the blame she gets. Maybe some days she believes it. But what it feels like is someone repeating a stock phrase about consequences to themselves. It's not genuine regret. She would do whatever it was again. Conflation of consequences with rejection/persecution.
This woman seems to have a martyr complex. She sees herself almost exclusively as a victim, of circumstance, of her own actions, I dunno. But she's [...] not got diminished capacity as far as I can tell. She's all there. The thing with "losing the thread" of the conversation looked like an evasion tactic or an attempt to make me feel for her. She doesn't want to answer things, so she feigns incapacity, because you can't blame a person for that. I dunno that it's that conscious, but it's there.
She talks with perfunctory attempts at conversation, but is more comfortable keeping the focus on herself [...] in a real roundabout way. Engage with sympathy and she takes it with only little hesitation. Comes out she wants validation for herself, but through your experience. I validate myself for doing this. You did it too, so therefore I validate you. It's twisted stuff.
