She visits him the night before he receives the letter, and his vague recollections but ultimate inability to place her in his past wakes her to the realisation that he is not the man she had thought he was, had hoped for and had projected onto her imaginings and . The letter brings into his mind a series of images and experiences that had been lost, that he had forgotten. But it is too late: she is lost to him. Lisa dies twice in the film.
