I think she kind of sounds like an ASMR recording, something about the precise enunciations on t‘s and c’s. But that’s just me. I get irritated easily by sounds.
At one point when she is reading from a court document, she notices that she’s going to have to say one of the kids’ names and she hesitates, and they tell her she doesn’t have to say it. Then later, she says one of the kids‘ names, no problem.
Also, didn’t she say at the police station that she told the hitman joke to the TV repair person on the day of the murder? On direct, Georgia asks her if she ever told that joke to anyone, and she denies it. That would have been a good time to impeach her with a copy of the transcript from her police interview. For some reason she didn’t do that. Either she forgot, or she doesn’t want to bring it up in this trial for some reason. Georgia does get her to admit that she told it to LaCasse and other people.
