Yeah i would take exception to the fact that she did not immediately grasp the significance of the covid. Otoh, what made it real to me is when Mary's husband's previous fiancee passed so suddenly on Downton Abbey. Still, it tells me this t is still deep in her denial, and that does not seem like a good place for a t to be. I mean, we all keep some denial, but hers is a little too close to the surface for me.
