Like I said before, I do think Emma is starting to trust him. She trusts that he can look after Henry and Henry doesn’t mind Hook’s company. The thing Emma still doesn’t trust, is her heart because like what Sarah said, she’s still scared of what would happen if she opens up to Hook and he breaks her heart.
Actually, one of my first thoughts about ‘A Curious Thing’ is that, maybe this refers to ‘love being a curious thing’ which is the actual title of a song.
I do think, Emma will be moved by Hook’s actions and what he went through in the year without her. I can’t imagine why she wouldn’t.
