This adds a lot of context.
First: if she paid for that second shitty model in full, it only made sense to ask for the subathon money before doing stuff, if true it shows that she couldn't outjew the jew after all.
Second: I knew about the %, but that's still a tall amount, if management was irresponsive and used that to blacken her public image, it makes sense as that can be used as strong leverage during negotiations.
I don't think she's lying but she is definitely holding a bit of information, as she can just tell only the bad things that happened without complementing it (for example, she said she paid for the model but I'd expect Aviel to refund her later and she didn't mention it, she wouldn't stay for months without it).
