I agree with most of your points, except I don't think that Andre could have detained her. He should have at least tried. But I'm not sure if he would have been able to, in her current mental state. Abby likely would have been what my husband refers to as "crazy strong."
When he was a cop, one of the calls he got fairly regularly was to a house where the wife had suffered a traumatic brain injury and had became very temperamental and violent. The husband stayed because he knew the brain injury was the reason she was that way, and he took his vows seriously.
Anyway, my husband would get to the house and she'd usually attack him. It was all he could do to restrain her. He's a big guy, 6'2", at the time he was about 250 lbs., in good physical shape. She's a tiny thing, 5' and about 110 lbs. But she'd worked herself into a rage and was crazy strong.
He tells of one time, she was trying to burn him with a cigarette. He's got her half pinned across the kitchen counter, pushing down, and she kept raising her hand to burn him, and he'd slam it back against the edge of the counter - over and over again - until the husband got the cigarette out of her hand.
Here he is, over a foot taller than her and more than twice her weight, and he was becoming concerned about his ability to keep her from hurting him. - and it was a heck of a struggle to get her under control enough to cuff her and put her in the patrol car!
When folks are in a state like that, adrenaline is running high, they are incredibly strong, and really don't feel pain. Instead of rage, Abby's would be a fear response, but her mental condition would ramp up the response intensity, making her nearly impossible to detain.
