It's interesting. Someone posted an article here yesterday that was written by a diagnosed sociopath. He/she talked about this incident as a child where her appendix burst and she was sent to school. She said she was so focused on containing any signs of her pain that she forgot to act normal so to speak and the mask slipped. I think this is what we saw with Jodi whenever she had to face Martinez. She was so focused on keeping her lies straight and containing the intense rage that was building up in her for him that the mask slipped. She couldn't contain her sociopathic and narcissistic need to have complete control and power. Even when she was supposed to be breaking down she still had the presense of mind and stillness to get in her little zingers and trade barbs. On the last day of cross the hatred she felt for him had reached its height. It was palpable. When Juan busted her on the gas cans she was able to somehow act very normal and calmly explain away that she'd returned it, but she could barely contain her rage in that moment either. Her eyes just totally gave her away, especially during sidebars. It's as if she's thinking "Well played you ###hole." She knows she's busted but she doubles down anyway.
She also cannot see that you cannot pretend to have a sobbing breakdown one second and then two minutes later be fine and have people think that's normal. It's like she'd remember that she was supposed to cry and look distraught for a second but then the moment would pass and she would forget or just not care. Like on the day where Juan pulled out the pic of Travis and the courtroom freaked out. She didn't really have a reaction until she realized everyone else was crying and looking away that she realized she should do the same. You are so right that when she has no one to emulate she doesn't know what to do.
She cannot even contain her narcissism in her explanations for why she killed Travis and then lied. Her whole thing is I was scared what people would think of me and my reputation. Only a completely empty shell of a person would think this way, but if she explains in an emotional and sympathetic way, then surely people will get it. She doesn't get normal people don't react to situations the way she thinks we do. She cannot even admit that she was jealous of Travis dating other women. She doesn't understand that jealousy really is a normal emotion to have when someone we love does us wrong and moves on without us. That she can't admit to even an inkling of jealousy is suspect. She protests too much, for sure.
And her motion that she doesn't intend to show remorse because she feels none because the killing was justified is crazy. If I genuinely killed in self defense and in a fog, I would be absolutely distraught and horrified at my own actions I wouldn't be able to even live with myself. Most people would be beside themselves with remorse and apologize and throw themselves at the mercy of the family and friends and the courts. Not Jodi. She think remorse is weakness and it's admitting guilt or that she did something wrong. And Travis had it coming, doncha know, so why should I feel remorse? Cold.
