@inthehands @dimsumthinking My impression from the interview is that she was always a person of perky character who liked making weird vocal noises. So I think the arrow of time doesn’t allow for your theory.
I did notice when I was finding the link that it was only the first of two episodes. The shownotes for the second suggest there may be more about her actual work. For you – *just* for you – I’ll listen and report back.
