Season 1 Throwback Tidbit
Something I remembered from Season 1 - part of the original Dark Curse - and correct me if my memory is faulty.
Emma cannot die. That's the pickle Regina was in S1 - she had to take care of Emma without killing her (hence why she turned to the poisoned apple with Jefferson.) The Dark Curse hinges on her remaining alive.
So, we'll see how this plays into Emma's visions.
