okay, here's a crackpot theory I came up with today: in Changelings, Belle (possibly accidentally) stabs Rumple with the Dagger and becomes the new Dark One - and the one who kills Emma. Robert sticks around as the voice in her head like he did in Season 5A. This would explain the "sacrifice" mentioned in the press release.

Probably not, but I'd love to see a Dark Belle storyline. It would give her a better understanding of Rumple, and give Emilie the chance to stretch her acting skills to the limit after sitting around doing nothing for six years :P
