My point did not have to be timeline specific. As I mentioned ^^^, seniors often communicate illness to sons/daughters. I know this from experience. The lunch purportedly involved a mediation of some kind, and Simon evidently was scheduled to be involved. Given those parameters, it seems likely that the 4 (or at least his parents) conveyed info about the lunch and/or the follow up illness to their son.
I considered EP might be innocent for all of 5 seconds into her Q and A with reporters outside her home. I reached that conclusion from my own observations without input from other sources (or here). As a profession, I am especially focused on how people use language. Before that, I was in the innocent camp.
