I know this is supposed to be a Zelena/Dorothy centric episode, but anyone think/hope it could have something to do with Snow and Charming sharing a heart? The writers always said they will address the repercussions of that at some point, and since that is exactly what Emma wants to do with Hook, perhaps this story line comes back full swing. Maybe Snow and Charming can only last so long with one heart. Although, I do like the idea of them needing to get out in a certain time frame otherwise they will decay, die, and be trapped in the UW.
Good point. Seeing the bts photo of Snow crying, it must be about a consequence. If they stay in the underworld with a shared heart something terrible will happen to them. This will complicate things for Emma, she would never want to lose them. She will have to get them safely out of the underworld fast before it is too late.
