Constance-Cosette relationship

The friendship between housewife Constance Bonacieux and Musketeer Cosette D'Artagnan is an extremely close sisterly one between the two women.

At first, the two of them do not get along and Constance think it is foolish that Cosette is pretending to be aboy to kill Athos. However, they begin a friendship after the ordeal is over. Cosette even allows Constance to call her "Cos," a nickname all her friends use. Constance even keeps her secret from Athos, Aramis and Porthos and helps Cosette sometimes embrace her feminine side.

However, their relationship is strained when Bonacieux, Constance's husband threatens to reveal Cosette's secret to the Cardinal if she doesn't break her friendship off with the young woman. Of course, Cosette is unaware of this and is actually heart-broken when Constance breaks the friendship with her.
