This detail isn’t actually as fanciful as it sounds: depending on the species, swans
can live for 20 years or more. More remarkable than the bird’s longevity, however, is the endurance of the couple’s love affair. Despite their distance and the damsel’s marriage, they remain in love and apparently undetected. This is another case where Marie’s sympathy is clearly with the adulterous couple rather than with the unwanted, unloved spouse. Meanwhile, Milun’s son comes back into the picture, apparently taking after his father despite never having known him.
