My family is so talented. My sister pointed out that instabilité really means instability. Duh. And while I do like the unraveling thing that is going on, I really am not unstable. Nor do I want to project this image. (Unless it might help my career? kidding.)
So, the new title is Denouement/Indéterminé. Impermanence of the indeterminable variety, not instability.
Merci professor Gilbert!
