It’s hard to explain, but there are people out there who believe reality is way more flexible (and personal) than the general population’s understanding of reality. Psychopaths are one of these categories (not murderers, I mean just plain psychopaths who you probably know), so are narcissists. Their version of “reality” is what they believe, and what they’ve managed to get those around them to reflect back at them.
One of the societal problems with these people is there really isn’t a “come back to reality” state for them, it’s just what’s in their head (the most preferential conditions for them personally) and brute force or charm or manipulation to get others around them to buy in. They don’t ever accept that common reality is non-preferential to them, so they relentlessly fight against it until a much stronger force restrains them. And even then they will continue to fight against that force, because they really CAN’T integrate a reality where things aren’t to their specifications.
A spooky thing about this personality trait is that it often works, because the person’s conviction in their rightness is so strong it makes neurotypical people start second-guessing themselves, since THEY would only be so certain with a strong bedrock of fact - so they assume there’s a factual basis they’re missing, when actually it’s just a personal determination to “set things right”.
Do I know if Alice is diagnosable? Nope, and I wouldn’t even try. But a lot of the traits she’s showing (the narcissism, the parental alienation, the storytelling, the documentable own-goals on the DVRO) are so divorced from fact and common understanding and even a grasp of repercussions that it seems like her take on reality is less our shared reality and more her belief of “how it should be”. But I don’t actually think in her mind there IS any other reality than that should-be universe, and that explains her actions, her disbelief that repercussions are landing on her, and her confidence to keep fighting until the “right” outcome prevails.
That’s really the only way I can explain her letting these things come to trial and go into a public court record.
