That’s why I’m suggesting that the people leaving be swept in a curse that takes them back to the EF and then next season is about the ones that stay find their way back to reunite the whole family.
If it was one person leaving then sure maybe a death but this is more than half the cast. The story reason has to make sense. Not seeing 5 deaths happening.
I don’t see them killing off Emma. It would be probably the worst mistake this show has ever made, and I doubt they want to prove the point of Jafar the villain that saviors don’t live happily ever after.
It’s better to write Emma and Hook off that way. Together than the other way cause that is just very depressing. And it also doesn’t mean Emma’s abandoning him. She’s going off on her honeymoon. That doesn’t mean forever and Henry can always bring her up in dialogue should she stay. It could still be referenced that he sees and lives with her at times.
