It is common, when discussing the duality between Judith and Olga, to place Judith on the side of "light" and Olga on the side of "dark" (after all, Judith is committed to reconciliation whereas Olga seems to see no solution in this life). This simple opposition though is belied by Olga's first appearance in the film, which is prefaced by these mysterious lines (spoken, I believe, by Juan Goytosolo): "Light is the first visible animal of the invisible." Not only is Olga introduced in relation to light, but she also exudes pure radiant energy here. A being in motion. It is a beautiful image that has stayed with me for the past half dozen years since I first saw the film.
