.I love Jim's take on CMJA. I've watched every Crime Time where he talks about her.
Who did she fool? Darrell, Matt...nearly everyone (including the Hughes).
Nurmi made a big deal that she left DB thereby squashing Dr D's theory, but she chose to leave all of them. The difference with Travis is that they never lived together. All the others she 'loved' and left she had been living with.
Yes and no. She did absolutely fool people but I think it's more whom she fooled than her prowess as a psychopath. I think it's likely that those she fooled would have a hard time believing
any petite, young, relatively attractive female capable of such deviance. It can be really difficult, and for some impossible, to come to terms with someone so inhuman.
Jodi used what she could to manipulate. She would have deliberately come across as sweet, innocent, humble, pious to the Hughes...and flip into the naughty girl routine, as needed, with potential love interests. She'd be the type to offer to do your grocery shopping for a year or drive you to church in another state - not because she wanted to - but because she could appear helpful. She needed to be needed and irreplaceable. That was her way of hooking people into her reality.
What she lacks though is sophistication. Any psychopath can maintain their facade for short amounts of time. Under scrutiny though, it all begins to fall apart. There's just no better example of this than her 18 days on the stand.
As far as Travis being different...you hit the nail on the head. I've said many times one only leaves a psychopath at their own peril. Normally, the relationship pattern of a psychopath follows 'Idealize. Devalue. Discard.'. You are never luckier than when they choose to discard you. When they don't, and you get tired of being their door mat and do leave, hell itself is unleashed.
What they can no longer control, they seek to destroy.
All JMO and FWIW
