Blue Fairy – unlikely, especially that she’s also a nun so she probably wouldn’t be lured by Hook’s ‘sweet’ words…
True but in the words of Dr Whale “Are the nuns still nuns or can they,you know, date?”
Hook plays whatever angle works best. He tried the “poor me, I survived a massacre” angle when he first met Emma and when that didn’t work, he tried the honesty angle instead.
With Blue Fairy, I can see him appealing to her sense of the greater good. He won’t try and sweet talk her in the traditional sense but more along the lines of “Don’t you think the world would be a better place without the Dark one in it. Help me and I’ll make sure that ideal becomes a reality”
