When Elio and Oliver leave for Rome in such haste that they forget to say goodbye to anybody, Vimini is hurt. She tells Elio this when he returns, pointing out that he never told Marzia that he was leaving and suggesting that Marzia knows he doesn’t care about her. Later, when Vimini dies, Elio writes to Oliver, and his return letter suggests he’s quite moved by her death.
