Mercédès tries to persuade the Count to come with her to the garden and eat some of the fruit there, but the Count refuses.
Mercédès gets annoyed, "are you my friend or what?"
The Count assures her he is her friend, and then they talk about their past in a vague way. They still don't acknowledge that they were once madly in love with one another, or that they know who the Count really is.
Then, Mr. Villefort shows up looking for Mrs. Villefort and Valentine.
Villefort's former wife's (the one who died really young) father-in-law, the Marquis de Saint-Méran, has just died.
