If this curse really did put an end to all other curses, perhaps Rumple thought that would make it impossible for EQ and others like her to destroy people again; it would also make him a human again; and it would mean people would have to turn to each other instead of magic to solve problems. All around, it seems to be a good deal for everyone if magic is replaced by free will and love.
Darcyfarrow, you’re right that the “curse” made Rumple “human” again. This makes me think now of how his son was scared of him when he turned into the dark one…so now, he’s found a way to reverse his own curse? Was that his intent? But, why would he want the curse to be broken and want to know Emma’s name in the first place? Questions leading to questions, which is why I love this series 😆
