I feel like her dementia isn't nearly as bad as they've claimed. I know she supposedly plays it up for the camera but when she's in front of a judge, I expect that she'll sober up quick. She's always kind of protected Chris, although when it's her ass versus Chris', it'll be interesting to see what path that takes for sure, if she's the "sober" party here, having consentual sex with your autistic child is a bad look for sure.
I expect the trial to goes as follows:
Chris vs Sober, Consenting Barb: Barb serves time and Chris getting help or put into a mental institution as Chris would be the one being taken advantage of in this situation.
Chris vs Dementia'd, Consenting Barb: Both of them end up being placed in a mental facility as both are clearly unwell. Chris might possibly still serve time.
Chris vs Nonconsenting Barb: Regardless of if Barb is dementia'd or not, Chris would get jail time for either of these scenarios and Barb would be placed into a home.
I believe Chris has at least a 50/50 chance of jail time vs being placed in an institution when all scenarios are considered, if not higher. There is almost a 100% chance Chris is not going to walk out of this unscathed. Depending on Barb's defense and position, even if she was consenting, if she chooses to throw Chris under the bus to avoid any charges herself there is enough evidence with the texts & voice call to back up that she was raped or at the very least, coerced.
