This is not a discussion of Greenberg's paper at all, but rather Bach's own interpretation of the film. Oedipal triangles are repeated several times among the

characters, in different generations and in the past, present, and future. Isak is terrified of death because of his narcissistic isolation; by reconciling himself to the union of his parents, symbolically expressed by his offer of help to his daughter-in-law, he changes his internal perception of death from oblivion to a primal reunion with his parents.
