One way you could possible do this is by, when Rapunzel is remembering her child hood, so her parents. as in the movie she has a flashback but instead of a flashback you could turn it into a dream sequence. you could also make another dream sequence about flin rider. as you probably know, Rapunzel has a crush on him, most likely making her think more about him, or dreaming about him. this one you could also make it humors, since we all know flint is quite a charmer. 
hopefully this helps you!

The teacher walked into the classroom, it was first period, he started to stare at everyone with a stern look, he noticed that most of the students in the class were asleep, he started mumbling to himself, “can I really be that boring?” because clad didn’t even start yet, a student heard him and replied, “no you’re not boring, you forgot it’s Friday? we don’t do lessons on Friday we watch a movie about what we learned about” the teacher looked up with a confused smile on his face “oh yeah that’s right, I honestly been so busy grading I forgot” he then proceeded to sit at his desk and prepare the movie for the kids.
