Flash back to show Rapunzel in the forest imagining what the prince was doing without her. A dream sequence could be the mother imagining what Rapunzel would taste like, or how the King imagines what Rapunzel looks like.
<u>Explanation:</u>
You could use the flash back to show Rapunzel in the forest imagining what the prince was doing without her. Such as, "Rapunzel sat in the dark forest. Though she had two children, she was completely alone. She began knitting a new pair of socks for her children, and humming an old familiar tune. She though back to how it all began." and then switch back and forth between the beginning and her waiting. A dream sequence could be the mother imagining what the Rapunzel would taste like, or how the King imagines what Rapunzel looks like.
Flash forward would be the opposite of a flash back. In stead of thinking about what happened, you think about what will happen. Like from the witch's perspective. She knows what is going to happen before it happens. You cold have the first meeting between the father and the witch, and when the father takes the Rapunzel back to his wife, you flash forward to the witch telling Rapunzel to let her hair down.
I guess a better example would be to show the witch convincing the father to give Rapunzel to him. You could flash forward (the witch showing the father) what would happen if the mother didn't eat the Rapunzel. "The witch then pulled an old mirror from her satchel and told the father to look in to it. He saw himself crying while his wife and unborn child died because he was unable to bring the Rapunzel to her" This would be making the Rapunzel magical, though.
