The film's climax reveals that the Red Shoes are not a gift but a curse created by the Queen to steal youth. The twist in the curse of the seven dwarfs is that it wasn't just about finding a "beautiful" woman, but about redefining their understanding of beauty. In the final confrontation, Merlin sacrifices his life to save Snow White, proving his selflessness.
Snow White kisses the dying Merlin—a kiss of true love—which revives him. Crucially, Snow White does not stay in her thin form; she remains her natural, plus-sized self. Merlin returns to his human prince form, but the ending emphasizes that he loves her as she is. The curse didn't just break; the worldview that created the curse was shattered.
