Some other prince who heard of the story of Rapunzel. The old witch did not imprison Ruby, but simply raised Ruby in her tower. The witch used magic to blind the prince to make sure that he loved Ruby not simply because of her appearance, and then Ruby left the tower with her boyfriend by their own, without any interference from Ruby’s godmother. When they passed the witch’s tests, she broke her spell and Ruby cried for happiness. This is truth, rather than Ruby was a witch and used tears to heal eyes of the prince.
