Yes exactly, but I think it might also tell us something about how his mental health declined over the years. Something was causing him to go back and start fixating on things from the past like that event he attended. I am curious if he told anyone he thought he was poisoned after that night in the days/weeks after or did this not come up until recently when he started saying all the other things.
Edited to add: I see the post about his name change in 2023, so it seems maybe the key timeframe is somewhere in 2022-2023 and maybe he had some increasing or worsening issues that caused the name change and all the court cases.
