Unless you know something I don't, I don't ever really get the vibe that she intentionally plays a victim, I feel like sometimes she barely processes things (due to chronic malnutrition, maybe? I don't really know how these things work) and is probably easily manipulated by people, which makes her claims of not knowing bad shit was going on seem a lot more genuine than if it was anyone else talking about it.
There have been times in the past few years that Eugenia genuinely seems to be in the dark (via not really processing information, or people in her life keeping certain information away from her) about a lot of shit. I feel really bad for her, as I'm sure most of us do.
