I’ve also been very suspicious of Blue since 1×19 The Return. Something that I want to add is that Blue has been alive way longer than Rumple (maybe she was born when Fairy Tale Land was created because she is the original power) & it seems like fairies can’t really do anything else but work all the time! That land seems to depend on the fairies (mostly) to survive imo, & so the fairies couldn’t actually have a personal life of their own. They can’t fall in love or even visit FTL for leisure (only to work granting some human a wish). So wouldn’t she get angry & frustrated with such a LONG work-only type of life? I think that even if she wanted to quit & lose her wings in order to find her own happiness, her sense of responsibility & I’m sure everyone else would have oppose her to do it (maybe FTL would have been destroyed or something if she quit). Because of that, even escaping to our world would have been out of the question. BUT if not only her but the whole FTL & its people traveled to our world (the curse), then the whole blame falls on the ones that triggered it Regina (& Rumple) & now that she’s human in a world that doesn’t depend on her she can actually have a life & it’s not a work-slave anymore. 🙂 Honestly I would have done the same in a situation like that…
