You give her all sorts of human emotions she doesn't have!
Usually we see narcissists pair with empaths who are unaware, but here, we see two narcissists on the same stage. I don't think she's capable of love. She's capable to memememememe. FD held promise -- to serve her need. His money, her lifestyle. Till she learned he didn't have any money (which he no doubt framed differently -- blaming the divorce on his finances -- when the truth was he was overbroke, clawing for money he had no right to. Those two, clash of egos. Clashes can be noisy, sexy, intoxicating and indeed I think it was for these two cheats.
She was NEVER protecting FD. She was protecting herself. There is only one person in her universe -- everyone around her is IN or OUT based on her immediate need for them.
Her playback has one trick. Lie. Repeat the lie. She hasn't embellished, she hasn't spun a new story where FD is the villain and duped her, barfing up invented details to confirm it.
To me, that's the confession.
If she could extricate herself from the murder of JFd and hand FD and KM to LE she would have, in a heartbeat. She's faithful to no one. She can't build a story that implicated them while disimplicating herself, she's that deep in it. She ordered the code read.
She hasn't even turned on KW. Fd was a smart man -- cruel, terrible but smart -- in the sense that no one could turn on the other.
There's all this talk about her lies. Her misrememberings. None of it's even novel. If it's not on the timeline, it didn't happen. She's not a good liar, she's just a repetitive one.
She does have some natural charm but I think the word is beguiling. Not to be trusted.
