I am very fascinated by Jodi as well. I think one thing that makes Jodi such a good liar is not that she tells really good lies, it's that she is so sincere and real and believable and sugary sweet when she tells them that you take it for what it is. It isn't until you start dissecting the content and digging deeper that the cracks begin to show and the logic falls apart. Of course, she's ready with another lie all ready to go. But the more she talks and the more she adds on, no matter how good or even logical it sounds, the more you don't believe her to where you don't believe anything. Sure, the jury might have gotten a little bored of Jodi after her 8 days on direct examination, but they were maybe giving her the benefit of the doubt and at least considering what she was saying. I bet that it wasn't until cross examination that Jodi lost the jury for good, because her lies just fell apart, one by one.
Another thing she is very good at after telling you a lie and getting caught, she will twist everything around to make you think you are the one that heard wrong or misunderstood one small part or that she misspoke and just needs to clarify. She's so slippery and so cunning at this that it makes you question yourself. You can be sure you heard it, but after a while you wonder if you really did just get it wrong. She even did this to ALV and to RS. They either believed her when she said they'd heard wrong, they knew she was lying and they were just covering for her, or they have a feeling that hadn't gotten it wrong but aren't really sure or just want to cover for her anyway. She did this all throughout her testimony. No wonder Travis began going crazy with her. She would set him off with a lie or with crazy behavior then make him feel like the crazy one and feel guilty for ever thinking such horrible thoughts about someone who was little crazy, but otherwise sweet and harmless. Anyone would have gone crazy in his situation.
And lastly, the problem with JA and probably most sociopaths is that they don't think or feel they way non-disordered people do so they basically have to fake it or pretend or try and figure out what would sound good to us. Sometimes what ends up coming out of her mouth is weird or just downright crazy. She may think it sounds very logical and poetic and sincere and sweet when in reality it's just all wrong and even chilling. Like the whole, "smile and say cheese," thing. To her, it made perfect sense and she thought it would make perfect sense to us. No. Her calling Det. Flores to "help the investigation" just ended up solidifying her as suspect number one. Her sending the flowers to Travis' grandmother, Irises, because Travis wanted to name a girl Iris, just made her look heartless and cold and calculating and mocking even. Finally, her comment about Travis being in a better place and his family's pain only being temporary but "so very much right now" is shocking. Jodi doesn't understand that this kind of pain never goes away and will remain forever, no matter what she says, because she cannot feel empathy and wouldn't care if someone close to her died. She has no idea that the pain isn't temporary. People don't just get over it. She probably can't understand why Travis' family won't get over it or she can and it just pisses her off.
