After Jules’ grand, Shakesperean speech, it should surprise no one that Jules decides to stay on the train and run away like planned in the season finale. Having Jules leave in such a manner, especially when it looked like Rue might go with her, is a perfect final rejection of the MPDG trope. The MPDG exists to improve the life of the lost protagonist, teach them how to truly live it, and if the MPDG does leave it is only after helping the brooding hero obtain a better life and outlook of their own. This is definitely not the case with Jules. She continues to break rank with the trope by showing that she’s not always very thoughtful when it comes to Rue’s needs by dismissing Rue’s warnings that she forgot her meds and needs them. After Jules leaves her, Rue is heartbroken and seemingly relapses, giving us a tragic end to their romance (for now) and throwing the MPDG trope in the trash where it belongs.
