You were laying your eggs near the pond five cyglets hatched with one hatchling being a duckling the duck's siblings and you actively shamed him for how he looked and being different until one day the duck disappeared mysteriously one night and your kids became adults and you told them to find places of their own now as the swans reminisce about the past it gets dark and a shadow figure appears in the background and snatches Simon (one of your ducklings) and then goes after Sylvie (also one of your ducklings) you then went to the barn to see if your ducklings have gotten kids yet when you entered the barn you saw dead corpses of your ducklings and then a shadowy figure is revealed to be your son he was covered in your siblings feathers and has human like teeth in his beak

Ugly duckling: everyday I woke up everyday I was reminded that I am inadequate, You're a freak, An Ugly freak, Your feathers, Your beak, Good luck trying to keep your perfect family it will be hard to continue your pure bloodline if everyone is dead You want to know what I've done? I think you know I have become beautiful no one come looking for me when I disappeared... and now no one will come looking for you
