Mlle. Renée de Saint-Méran
As with Mercédès, there's not much to Renée de Saint-Méran. She's kind and caring; she's feminine; she appeals to Villefort's good side. After she dies, she represents the good and caring wife – and perhaps the good and righteous life – that Villefort could have enjoyed if he'd walked the straight and narrow path to goodness.
