I just posted this in spoiler tags in a thread on the regular forum, but wanted to mention it here too.
The thread was about Cora’s powers, and whether or not Lancelot is really dead. I wondered if Cora can only shape shift into being someone she’s killed, or someone who’s heart she’s stolen. Then I remembered that Regina was apparently gonna be seeing Daniel’s ghost. Could that somehow be Cora appearing as Daniel in SB?
Edited to add another thought I had just now reading another thread. Maybe those ashes of the wardrobe that Cora collected wouldn’t have enough power to transport her, but would have enough power so she could astral project, in a sense. That could be how she’d appear briefly as Daniel’s ghost in SB, even if she’s not yet in town.
Edited again to add that maybe she doesn’t appear as Daniel’s ghost at all, maybe Regina actually sees Cora? I know that Barbara isn’t in the cast list in the first post of this thread, but perhaps it’s not a complete list yet?
Mmm, Jane Espenson just tweeted to fans that this, 
So now I’m wondering what’s going on. I agree though that I think it might have something to do with Cora. Of course, I’m hyped up on the impostor theory becoming true, so I would love if your scenario came true and we find out at the end Daniel’s ghost in Storybrooke was really Cora.
My second guess, even though he’s not listed in the credits either, is that maybe it has something to do with Michael Raymond-James at the end of the episode because next week is the “Tallahassee” episode. Although I don’t know that would make it the best ending ever because I’m expecting a really, super shocker ending even though she just says “best ending ever” because to me that would be one of the best endings ever.
