Before I go to bed I just wanted to discuss this moment:
Emma is near pleading Hook to just give up his revenge/selfishness and just join them, be a hero. This in itself shows the fact that Emma does now consider herself a part of a family and that she does believe she belongs somewhere.
But I want to talk about Snow and Charming. In this brief moment, specifically. Neither of them never quite knew what it was to be abandoned, to honestly have no one want them. Snow always made friends where ever she went (let’s be real: Red, dwarves, peasants, hell even Regina had twisted sympathy for her at times) and Charming was always loved by his mother, even when he was forced to leave her.
I felt like they almost didn’t understand why Emma had always been so hell-bent on protecting Hook (I’m referring to the hospital scene). Or specifically, what she sees in him that is worth her passion. You can see it in the way Snow cocks her head to the side, typically a sign of confusion. But it’s Charming, who gives this tiny little nod at the end of Emma’s speech. He saw Hook being a hero, even if he doesn’t like Hook, Charming can’t deny that Emma might actually be pleading a good case.
I think this was the moment where both of them must have noted that Emma was the only one who could talk Hook down. Why didn’t she just appeal to his general sense of decency like with anyone else? Instead, Emma appealed to his loneliness and need to be loved which neither Snow nor Charming could ever quite understand or have done. I think that is where Snow’s true confusion lies: why would this pirate care so much about belonging?
