The Fairytale Grade - the small references and nods to the original fairytale by the Brothers Grimm that most people probably don't notice. 
 The Rampion. In the original fairytale, the plant Rapunzel's mother wants is referred to as both rapunzel and rampion. WHICH IS WHERE THE NAME OF THE SHIP COME FROM. +20 POINTS for Marissa Meyer's brilliance! 
 The desert. In the original, Rapunzel is banished by Dame Gothel to a desert, and that's where Thorne and Cress land. +10 points! 
 Blindness. The prince gets blinded in the original, and so does Thorne! +10 points! 
 Thorne. The prince isn't named in the original, but he gets his eyes poked out by thorns... Marissa Meyer... you're amazing. +10 points! 
 50 points for Cress!!! *applauds* Anything you think I missed?
