Rapunzel was never saved by Flynn Rider. He did take her to see the lights, but in the end, he only cared about money. The princess was forced to return to her tower and live a miserable life, believing she would never escape her "Mother's" grasp or learn about her true identity.
However, everything changed one day when she had an unexpected visitor, Jack Frost. Jack was drawn to her voice and couldn't bear to leave her in her poor state, so he freed her, and they flew away together into the night. He taught her about the world and herself.
Over the years, they fell in love, married, and went on to have two daughters, Elsa and Anna. Elsa was born with powers that were stronger than her father's, while Anna was born without powers. They believed Anna would be just as powerful as her sister once her powers surfaced. They were a picture-perfect superhuman family, but what could possibly go wrong?
I want to clarify that I don't own any of these characters. Disney and Dreamworks do. I came up with this story after seeing a Jackunzel illustration where Elsa and Anna were their children. I ship both Jackunzel and New Dream (Rapunzel x Eugene), so don't worry, you'll see some Raps x Eugene moments in later chapters. I may also add some other Disney/Dreamworks characters down the line.
