The younger of the Sauveterre sisters, Arlette sometimes gets annoyed with her mother Astride‘s go-with-the-flow attitude. Arlette is very much a free-thinking, eschewing marriage to be on her own instead. She often visits Kilian and Onésime and gossips happily with the younger generation (though not maliciously). She disapproves of her sister Armelle’s marriage and the way her niece Brigitte and nephew Aubert are being raised, and offers to babysit them very often. She has also encouraged their friendships with Nolwenn, Calixt, Dorian and Haydée.
