LVD is a narcissist with a complete self focus - no question whatsoever. In general, I see no benefit to ever cater to her whims. And I think the judge is very aware that LVD - in general, and in her similarity to how prisoners can be - could be faking or just lazy and not wanting to participate.
However --- people do get sick. And when you're sick, with things like ongoing nausea and what comes with it, you feel like total crap and can't really navigate life until you get well.
The judge didn't take her word for it, and hauled her into court to check it out. But to be fair, he shouldn't act like he wasn't told, or that LVD getting sick isn't possible. Oddly, she's human - very much so in every way, even if she at times tells herself otherwise.
To be honest, if I was nauseous and weak, I have to admit I would be saying and doing almost the exact same things that LVD is saying and doing. I wouldn't want to be dragged somewhere to prove I'm sick (making me feel even worse). I wouldn't want to engage with others. I would be aware I didn't choose to be sick and just want to be allowed to recuperate. There is NOTHING in what she's asking that's any different than anyone else.
In general, I don't want to side with LVD because of her life choices, but when someone is truly sick (which is very possible here, who knows) then we need to treat them as we would want to be treated. It may be inconvenient to the court for a defendant to get sick, but it's not something they can choose, and if it happens, be fair and considerate, and circle back to the trial when the sickness has passed.
Just my 2c.
