Once Upon a Time Season 5 Video: Can Hook Summon Dark Emma to Return?

Storybrooke, we have a problem.

As seen in this sneak peek at the opening minute of Once Upon a Time Season 5 — and as Ginnifer Goodwin and Josh Dallas told TVLine at Comic-Con — getting Emma back after she merged with the Darkness and thus became the Dark One isn’t as simple as commanding her via the dagger.

Press play above to get the heroes’ assorted reactions to Emma’s tragic vanishing (including Regina’s distinct “Now Emma’s a problem” POV) and find out why the dagger isn’t able to bring back the fallen Savior.
