They also said Emma and Hook's arrival in EF2 ties into the events of Hyperion Heights. Uhm... I believe it's about the 7x02 and other flashbacks. I think Adult Henry sends for help while he, Jace, and Tiana face whatever trouble is in EF2. I don't think it's directly related to the curse as Lucy wasn't born yet.

So, I think the reason his family goes there is to stop a problem, they think it's done, they leave and outta nowhere the villain returns, curses people and such. I doubt the villain selects a couple of residents who are in Storybrooke for his curse, those who are still in EF2 get cursed IMO. And even if Emma wasn't part of the curse (which she probably is, somehow), she'd surely come to help them in Seattle, she's not the type to stay behind.
