So in that Sneak Peek, Emma called Hook out on being selfish, then he tried complimenting her on her magic and she said she’s not embracing it because she WANTS to rather because she HAS to, which shows how he doesn’t really understand her, then she says she’s gonna take Henry back to NYC, which pretty clearly indicates that she has no plans to start dating a pirate in SB. So that was a pretty great Sneak Peek IMO.
Sad part about it though, I’ll bet part of the reason she wants to take Henry away is because she knows how much it would hurt him to remember his dad, now that he’s gone.
