The balcony scene, written from Rapunzel's POV. My take on what could have transpired between the time they got there and when Rapunzel's parents entered.
Two mothers. One daughter. One lullaby. The story of how two different women interacted with Rapunzel in very different manners, but both loved her in the end, as she loved them. Based on the Robert Munsch story of the same name. Oneshot.
This continues from the end of the film and further develops the relationship between Flynn and Rapunzel. The T rating accounts for the later chapters.
