Good. The more stressed she is, the better. She knows what she has to do. She knows what is next. She has always been one of Dulos' many weak links. When that dam opens, and it may have already, Dulos is going to see the likes of an information flood he could only imagine.
Getting cooperating a co-defendant to the point s/he becomes an effective prosecution witness is a process that requires great skill and it is one many people do not understand. It is not at all like it is portrayed, even in so-called true crime shows. A good investigator knows how to get inside a person's head. IMO Coangelo has been letting Troconis stew in her own half-truths. AW2 was his wake up call to her she better start telling the truth about what she did and what she knows.
I am not at all surprised that Troconis has not been honest, has tried to minimized her involvement, has had what I call a fuzzy memory. I don't think I have ever had a cooperator be 100% the first go round. IME it is because human beings never want to acknowledge their own bad behavior, although I have seen women truly "brainwashed" by their male partners (I do not think so here).
The psychology of it aside, though, she has only one path ahead of her, if she has any hope of protecting herself and righting some every serious wrongs she has participated in. I have no idea when her next debriefing is to be, but her next meeting with LE needs to take a clear path away from Mr. Dulos.
100% cooperation going forward. 100% truth, 100% assistance and 100% acceptance of responsibility.
