I would love it if we somehow end up with a situation where everyone can go back and forth from the EF to SB whenever they want. Like when winter is especially bad in SB, everyone spends a few months in the EF.
The cutest thing ever would be to see Emma and Hook helping each other figure out how to get used to each other’s “realm” – from the clothes they should wear and the food they eat, to dealing with electronics and the lack of indoor plumbing. Figuring out the popular music and entertainment, modes of transportation, slang and figures of speech. Both having to get used to the fact that Emma is royalty is the EF (would they live in the castle as well??); which I guess means that Hook becomes royalty if they do end up getting married on day.
They have so many amazing possibilities.
