Unless they turn the next season into a self-contained spinoff like Wonderland (which was awesome), I’m not sure how they can make Once work without Emma.
But I wasn’t sure how they could make it work with other decisions they’ve made, either.
What I really want Season 7 to be is that dropped vignette episode, but spread across a short Season. Actually deal with the stories that were left unresolved for characters like Will, Anastasia, and Lily. I doubt that’s a concept that would necessarily sell Season 7 to mainstream audiences, but it’s what I’d personally want. It’s what would justify Season 7 existing for me.
