Jean Santeuil
2.4.2 Mme S*
[proto-Albertine]
(a) Makes him jealous. NB: it's clearly already important for Proust to have not one but two love plots, one more credulous, one more disabused. "Elle ne lui représentait ni plus d’intelligence ni plus de bonté (il... n’essayait plus de se le prouver, comme quand... il croyait à l’absolu de l’amour). (Dire dans l’histoire Kossichef qu’il voulait se persuader que Marie était intelligente, sans guère y croire.)" (806)
Is he borrowing from Flaubert? (“Pendant qu’il rêve à Charlotte... Françoise répond... Mais la brièveté de son premier amour (Education sentimentale) ne le décourageait pas des autres” (812).)
(b)
Is bisexual, admits to having had sex with another woman (JS 790ff.). (In this scene the two female characters are called Françoise and Charlotte.)
[Compare "Avant la nuit" (1893), in which a narrator, also called Françoise, is confessing to her lover that she has had sex with women during their time together.]
(c) There's a period of overlap here, during which Jean is with Françoise, but thinking of Charlotte Clissette (816-20). ("Certes il dirait très franchement à Françoise sa sympathie pour Charlotte et n’irait pas avec celle-ci... au-delà de l’amitié." (819)) Compare perhaps the interlude with Mlle de Stermaria?
* also known as Mme Griffon (788ff.), Françoise (e.g. 812).
