Episode Rewrite

Maybe it's an episode Rewrite. In which case which episode gets the Free Use Treatment in the Once Upon a Time universe?

How did Emma really become Sheriff?

Does Emma think of a more fun way to pay off her debt to Gold?

How do Snow and Charming get to know their grown up Daughter?

Do Emma and Gold join the Mile High Club when on their way to find Baelfire?

Or something else?

Suggestions welcome.
