You definitely get the impression that this person can't seem to grasp that they're now expected to settle down into an ordinary, dull existence. Their family looks exhausted and I could see them thinking that there was supposed to be an end point at which their lives would stop being just about this person and this issue and they thought they'd reached it, they've done all the things on the list, so why is there this drive to keep it going.
You know, there's something about this that I am noticing in my own (very parochial) life. We seem to now have a culture where it is perceived as normal for ordinary people to have storylines of ongoing drama, as though we all live in a soap opera.
I see it with family members, some parents at school, certain friends, some people I work with on civic projects: it's never-ending generated drama, often over pretty much nothing at all (or in the case of my SiL, another round of utter batshittery that makes no sense and is, in reality, legally impossible).
It has got to the point where I am absolutely fatigued with it, and now just refuse to engage (and to be blunt, I'm just too busy to give a fuck about dealing with their shit). But I do wonder why these behaviours have become so normalised in society.
I think there's now such a deep, internalised phenomenon of narcissism that quite a lot of people can no longer recognise that other people are actually real humans, and not just supportive NPCs in some grand biopic of their lives.
